Description

Technical Field

[0001] The present application relates to the field of computers, and in particular to a message transmission method, device and system. Background Art

[0002] As the system business becomes increasingly complex, the business traffic of the system is also increasing exponentially; in order to ensure the load balancing of the back-end servers (i.e., the receiving devices of the messages) of the system, the sending device needs to send the message to the load balancer, and the load balancer will divert the business traffic (or business message) of the system to different back-end servers. However, the way that the sending device sends the message directly to the load balancer will expose the source address of the message (i.e., the intranet address of the message), which poses a security problem; to solve the security problem, a common processing method is to use a proxy server to convert the source addresses of the messages sent by different sending devices into the same public address, and then the proxy server sends the converted message to the load balancer.

[0003] However, since the source addresses of the messages received by the load balancer from the proxy server are all the public addresses, when the load balancer performs load balancing based on the source addresses of the received messages, the load balancer will divert all messages to the same backend server, resulting in a load imbalance problem. Therefore, in the presence of a proxy server, how to perform message transmission based on a load balancer has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0004] The present application provides a message transmission method, device and system, which can realize message transmission based on a load balancer in the presence of a proxy server.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, an embodiment of the present application provides a message transmission method, which is applied to a message transmission system, the system comprising: multiple sending devices, a proxy server, a load balancer and multiple receiving devices; wherein, the multiple sending devices have a communication link with the load balancer through the proxy server, and the load balancer has a communication link with the multiple receiving devices; the method comprises: a first sending device sends a first message to the proxy server; the multiple sending devices comprise: a first sending device, the first message is a message to be sent to the receiving device; the source address of the first message is used to indicate the first sending device; the proxy server receives the first message and converts the first message into a second message; the second message comprises a message body of the first message, a source address of the second message and a source address of the first message; the source address of the second message is used to indicate a public address of the proxy server; the load balancer receives the second message sent by the proxy server, and determines the first receiving device from the multiple receiving devices based on the source address of the first message included in the second message; and sends the second message to the first receiving device.

[0007] The embodiment of the present application provides a message transmission method, which converts a first message sent by a first sending device received by a proxy server into a second message including a message body of the first message, a source address of the second message and the source address of the first message, so that the load balancer determines the first receiving device from multiple receiving devices based on the source address of the first message included in the second message, and sends the second message to the first receiving device. Although the source address of the second message is used to indicate the public address of the proxy server, the source address of the first message included in the second message is used to point to the first sending device; since the source addresses of the first messages sent by different sending devices are different, the load balancer determines the first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0008] In addition, since the source addresses of the first messages sent by different sending devices are different, the load balancer will not divert the messages sent by different sending devices to the same receiving device when performing load diversion based on the source address of the first message, thereby improving the load balancing of the receiving device.

[0009] In one possible implementation, the source address of the first message is carried in a source address field in the first message, and the first message is converted into a second message, including: the proxy server replaces the source address of the first message in the source address field with a public address, and adds the source address of the first message to the target field in the first message to obtain the second message.

[0010] In a possible implementation manner, the target field is a reserved field or a newly added field in the first message.

[0011] In an embodiment of the present application, a proxy server is used to replace the source address of the first message in the source address field of the first message with a public address, and the source address of the first message is added to the target field in the first message to obtain a second message; since the source addresses of the first messages sent by different sending devices are different, the subsequent load balancer determines the above-mentioned first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0012] In one possible implementation, the source address of the first message is carried in a source address field in the first message. Before the first sending device sends the first message to the proxy server, the method includes: the first sending device adds the source address of the first message in a reserved field or a newly added field in the first message; the above-mentioned conversion of the first message into the second message includes: the proxy server replaces the source address of the first message in the above-mentioned source address field with a public address to obtain a second message.

[0013] In an embodiment of the present application, a first sending device adds the source address of a first message to a reserved field or a newly added field in the first message, and replaces the source address of the first message in the source address field of the first message with a public address based on a proxy server to obtain a second message. Since the source address of the first message exists in the reserved field or the newly added field in the second message, and the source addresses of the first messages sent by different sending devices are different, the subsequent load balancer determines the above-mentioned first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0014] In one possible implementation, the above-mentioned determining the first receiving device from multiple receiving devices based on the source address of the first message included in the second message includes: the load balancer obtains the source address of the first message from the second message; the above-mentioned load balancer determines the first receiving device from multiple receiving devices based on the hash value of the source address of the first message.

[0015] The load balancer in the embodiment of the present application performs a modulo operation based on the hash value of the source address of the first message and the number of multiple receiving devices to obtain a modulo result; and determines the receiving device whose device identifier corresponds to the modulo result among the multiple receiving devices as the first receiving device. Since the hash value of the source address of each sending device is fixed, the modulo result obtained by performing a modulo operation based on the hash value and the number of multiple receiving devices is also fixed; then, each message sent by each sending device is diverted to the same receiving device each time; thereby solving the problem that when the message sent by the same sending device is diverted to different receiving devices, the authentication information of the sending device does not exist in other receiving devices among the multiple receiving devices except the receiving device that processes the authentication message of the sending device, which causes other receiving devices to be unable to process the message sent by the sending device, thereby improving the stability of the message transmission system.

[0016] In one possible implementation, the load balancer determines the first receiving device from multiple receiving devices based on the hash value of the source address of the first message, including: the load balancer performs a modulo operation on the hash value and the number of multiple receiving devices to obtain a modulo result; the load balancer determines the receiving device whose device identifier among the multiple receiving devices corresponds to the modulo result as the first receiving device.

[0017] In one possible implementation, the multiple receiving devices include receiving devices in different receiving groups, each receiving group including at least one receiving device; before determining the first receiving device from the multiple receiving devices based on the hash value of the source address of the first message, the method also includes: the load balancer determines the target receiving group corresponding to the bandwidth level of the second message from the multiple receiving groups; wherein different receiving groups correspond to different bandwidth levels; the determining the first receiving device from the multiple receiving devices based on the hash value of the source address of the first message includes: the load balancer determines the first receiving device from the receiving devices included in the target receiving group based on the hash value of the source address of the first message.

[0018] The embodiment of the present application divides multiple receiving devices into different receiving groups according to the bandwidth size (i.e., bandwidth level) of the messages they process; then, after the load balancer receives the second message, it determines the target receiving group corresponding to the bandwidth level of the second message from the different receiving groups; then, based on the hash value of the source address of the first message, it determines the first receiving device from the target receiving group. This avoids the problem of downtime of the receiving device caused by diverting messages with a higher bandwidth level to a receiving device with fewer resources, thereby improving the stability of the receiving device.

[0019] In addition, since the bandwidth levels corresponding to the multiple receiving groups are different, the target receiving groups determined by the messages of different bandwidth levels (such as the second message) are different. After determining the target receiving group, the load balancer determines the first receiving device from the receiving devices included in the target receiving group based on the source address of the sending device indicating the sending of the message (such as the source address of the first message), and sends the message to the first receiving device; thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0020] In one possible implementation, the above-mentioned second message also includes a bandwidth level of the second message, and the bandwidth level of the second message is used to indicate the bandwidth size of the first message. Before the load balancer determines the target receiving group corresponding to the bandwidth level of the second message from multiple receiving groups, the method also includes: the load balancer obtains the bandwidth level of the second message from the second message.

[0021] In a possible implementation, when the multiple receiving groups include: a first receiving group, a second receiving group, and a third receiving group, the load balancer determines, from the multiple receiving groups, a target receiving group corresponding to the bandwidth level of the second message, including: when the bandwidth level of the second message is lower than a first preset level, the load balancer determines the first receiving group as the target receiving group; when the bandwidth level of the second message is higher than the first preset level and the bandwidth level of the second message is lower than the second preset level, the load balancer determines the first receiving group and the second receiving group as the target receiving groups; when the bandwidth level of the second message is higher than the second preset level, the load balancer determines the first receiving group, the second receiving group, and the third receiving group as the target receiving groups.

[0022] In the embodiment of the present application, the above-mentioned multiple receiving groups include the first receiving group to the third receiving group. When the bandwidth level of the second message is lower than the first preset level, the first receiving group is determined as the target receiving group; when the bandwidth level of the second message is higher than the first preset level and the bandwidth level of the second message is lower than the second preset level, the first receiving group and the second receiving group are determined as the target receiving groups; when the bandwidth level of the second message is higher than the second preset level, the first receiving group, the second receiving group and the third receiving group are determined as the target receiving groups. It can be seen that the higher the bandwidth level of the second message, the more receiving devices are included in the target receiving group determined by the load balancer; that is, the higher the bandwidth level of the second message, the more options are determined for determining the first receiving device; thereby avoiding the problem that the receiving device processing the high-bandwidth message cannot use other receiving devices to process the high-bandwidth message when the available resources are insufficient, thereby improving the load balancing of the receiving device.

[0023] In a second aspect, an embodiment of the present application provides a message transmission method, which is applied to a first sending device in a message transmission system, and the method includes: adding the source address of the first message in the target field of the first message to be sent; the first message is a message to be sent to a receiving device; sending the first message to a proxy server; the proxy server is used to convert the source address of the first message carried by the source address field in the first message into a public address to obtain a second message; the public address is used to indicate the proxy server.

[0024] In a possible implementation manner, the target field is a reserved field or a newly added field in the first message.

[0025] In an embodiment of the present application, a first sending device adds the source address of a first message to a reserved field or a newly added field in the first message, and replaces the source address of the first message in the source address field of the first message with a public address based on a proxy server to obtain a second message. Since the source address of the first message exists in the reserved field or the newly added field in the second message, and the source addresses of the first messages sent by different sending devices are different, the subsequent load balancer determines the above-mentioned first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0026] In a third aspect, an embodiment of the present application provides a message transmission method, which is applied to a proxy server in a message transmission system, and the method includes: receiving a first message sent by a first sending device among multiple sending devices; the first message is a message to be sent to a receiving device; converting the first message into a second message; the second message includes a message body of the first message, a source address of the second message and a source address of the first message; the source address of the second message is used to indicate a public address of the proxy server; sending a second message to a load balancer; the load balancer is used to determine a first receiving device from multiple receiving devices based on the source address of the first message included in the second message, and send the second message to the first receiving device.

[0027] In one possible implementation, the source address of the first message is carried in a source address field in the first message, and the first message is converted into a second message, including: replacing the source address of the first message in the source address field with a public address, and adding the source address of the first message to a reserved field or a newly added field in the first message to obtain a second message.

[0028] In an embodiment of the present application, a proxy server is used to replace the source address of the first message in the source address field of the first message with a public address, and the source address of the first message is added to the target field in the first message to obtain a second message; since the source addresses of the first messages sent by different sending devices are different, the subsequent load balancer determines the above-mentioned first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0029] In a fourth aspect, an embodiment of the present application provides a message transmission method, which is applied to a load balancer in a message transmission system, and the method includes: receiving a second message sent by a proxy server, the second message including a message body of the first message, a source address of the second message and a source address of the first message; the source address of the second message is used to indicate a public address of the proxy server; determining a target receiving group corresponding to a bandwidth level of the second message from a plurality of receiving groups; wherein different receiving groups correspond to different bandwidth levels, and each of the plurality of receiving groups includes at least one receiving device; based on a hash value of the source address of the first message, determining a first receiving device from the receiving devices included in the target receiving group, and sending the second message to the first receiving device.

[0030] The embodiment of the present application divides multiple receiving devices into different receiving groups according to the bandwidth size (i.e., bandwidth level) of the messages they process; then, after the load balancer receives the second message, it determines the target receiving group corresponding to the bandwidth level of the second message from the different receiving groups; then, based on the hash value of the source address of the first message, it determines the first receiving device from the target receiving group. This avoids the problem of downtime of the receiving device caused by diverting messages with a higher bandwidth level to a receiving device with fewer resources, thereby improving the stability of the receiving device.

[0031] In addition, since the bandwidth levels corresponding to the multiple receiving groups are different, the target receiving groups determined by the messages of different bandwidth levels (such as the second message) are different. After determining the target receiving group, the load balancer determines the first receiving device from the receiving devices included in the target receiving group based on the source address of the sending device indicating the sending of the message (such as the source address of the first message), and sends the message to the first receiving device; thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0032] In one possible implementation, the above-mentioned second message also includes a bandwidth level of the second message, and the bandwidth level of the second message is used to indicate the bandwidth size of the first message. Before determining the target receiving group corresponding to the bandwidth level of the second message from multiple receiving groups, the method also includes: the load balancer obtains the bandwidth level of the second message from the second message.

[0033] In a possible implementation, when the above-mentioned multiple receiving groups include: a first receiving group, a second receiving group and a third receiving group, a target receiving group corresponding to the bandwidth level of the second message is determined from the multiple receiving groups, including: when the bandwidth level of the second message is lower than a first preset level, the first receiving group is determined as the target receiving group; when the bandwidth level of the second message is higher than the first preset level and the bandwidth level of the second message is lower than the second preset level, the first receiving group and the second receiving group are determined as the target receiving groups; when the bandwidth level of the second message is higher than the second preset level, the first receiving group, the second receiving group and the third receiving group are determined as the target receiving groups.

[0034] In the embodiment of the present application, the above-mentioned multiple receiving groups include the first receiving group to the third receiving group. When the bandwidth level of the second message is lower than the first preset level, the first receiving group is determined as the target receiving group; when the bandwidth level of the second message is higher than the first preset level and the bandwidth level of the second message is lower than the second preset level, the first receiving group and the second receiving group are determined as the target receiving groups; when the bandwidth level of the second message is higher than the second preset level, the first receiving group, the second receiving group and the third receiving group are determined as the target receiving groups. It can be seen that the higher the bandwidth level of the second message, the more receiving devices are included in the target receiving group determined by the load balancer; that is, the higher the bandwidth level of the second message, the more options are determined for determining the first receiving device; thereby avoiding the problem that the receiving device processing the high-bandwidth message cannot use other receiving devices to process the high-bandwidth message when the available resources are insufficient, thereby improving the load balancing of the receiving device.

[0035] In a possible implementation, the above-mentioned hash value based on the source address of the first message determines the first receiving device from the receiving devices included in the target receiving group, including: performing a modulo operation on the hash value and the number of multiple receiving devices included in the target receiving group to obtain a modulo result; and determining the receiving device whose device identifier among the multiple receiving devices corresponds to the modulo result as the first receiving device.

[0055] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0056] The terms "first message" and "second message" in the description and claims of the embodiments of the present application are used to distinguish different messages, rather than to describe a specific order of messages. For example, a first receiving device and a second receiving device are used to distinguish different receiving devices, rather than to describe a specific order of receiving devices.

[0057] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0058] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple sending devices refers to two or more sending devices.

[0059] Based on the technical problem of how to perform message transmission based on a load balancer in the presence of a proxy server raised in the background technology, an embodiment of the present application provides a message transmission method, which converts a first message sent by a first sending device received by a proxy server into a second message including a message body of the first message, a source address of the second message and the source address of the first message, so that the load balancer determines the first receiving device from multiple receiving devices based on the source address of the first message included in the second message, and sends the second message to the first receiving device. Although the source address of the second message is used to indicate the public address of the proxy server, the source address of the first message included in the second message is used to point to the first sending device; since the source addresses of the first messages sent by different sending devices are different, the load balancer determines the first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of performing message transmission based on a load balancer in the presence of a proxy server.

[0060] In addition, since the source addresses of the first messages sent by different sending devices are different, the load balancer will not divert the messages sent by different sending devices to the same receiving device when performing load diversion based on the source address of the first message, thereby improving the load balancing of the receiving device.

[0061] A message transmission method provided in an embodiment of the present application is applied to Figure 1 The message transmission system shown in the figure includes: multiple sending devices (such as sending device 1 to sending device X), a proxy server, a load balancer, and multiple receiving devices (such as receiving device 1 to receiving device N). In the present application, multiple sending devices in the message transmission system have communication links with the load balancer through the proxy server, and there are communication links between the load balancer and multiple receiving devices.

[0062] Any sending device among the multiple sending devices (eg, the first sending device) can be used to send a message to the load balancer through the proxy server; wherein the source address of the message is used to indicate the sending device that sends the message.

[0063] The proxy server is used to receive a message (hereinafter referred to as the first message) sent by a sending device, and convert the first message into a second message including: a message body of the first message, a source address of the second message, and the source address of the first message; wherein the source address of the second message is a public address used to indicate the proxy server, and the source address of the first message is used to indicate the sending device that sent the first message. The proxy server is also used to send the second message to the load balancer.

[0064] The load balancer is used to obtain the source address of the first message included in the second message by parsing the second message, and based on the source address of the first message, determine the first receiving device that receives the second message from multiple receiving devices. The load balancer is also used to send the second message to the first receiving device.

[0065] In this application, Figure 1 The multiple sending devices and the proxy server in the message transmission system shown can be integrated in the same computing device, or they can be independent computing devices; accordingly, the proxy server and the load balancer can be integrated in the same computing device, or they can be independent computing devices; similarly, the load balancer and the multiple receiving devices can be integrated in the same computing device, or they can be independent computing devices; the specific embodiments of the present application are not Figure 1 The representation of multiple sending devices, proxy servers, load balancers, and multiple receiving devices is limited.

[0069] In a possible implementation, the memory 202 may exist independently of the processor 201. The memory 202 may be connected to the processor 201 via a bus 204 and used to store data, instructions, or program codes. When the processor 201 calls and executes the instructions or program codes stored in the memory 202, the relevant steps in the message transmission method provided in the embodiment of the present application can be implemented.

For ease of representation, Figure 2 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0074] It should be understood that Figure 2 The computing device in the example is only one example of a computing device, which may have Figure 2 More or fewer components shown in the figure may be combined with two or more components, or may have different component configurations.

[0075] It should be noted that the system architecture and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0076] The present invention provides a method for transmitting a message. Figure 1 The message transmission system shown in FIG. Figure 3 As shown, the method includes: S110-S130.

[0077] S110. A first sending device sends a first message to a proxy server.

[0078] In this application, the first sending device is Figure 1 Any sending device among the multiple sending devices in the message transmission system shown.

[0079] In the present application, the first message is a message generated by a first sending device and to be sent to a receiving device.

[0080] Among them, the first message may include a message header and a message body, the message header may include five-tuple information, the five-tuple information may include the protocol version number, source address, destination address, port number of the source address and port number of the destination address; the message body includes the data or information to be sent by the first message.

[0081] The source address of the first message is the source address in the five-tuple information of the first message; wherein the source address of the first message is used to indicate the first sending device that sends the first message.

[0082] Specifically, the source address of the first message can be an Internet Protocol address (IP address) of the first sending device, or it can be a combination of the IP address of the first sending device and the port number of the port in the first sending device that sends the first message. The specific embodiment of the present application does not limit the specific form of the source address of the above-mentioned first message.

[0083] In the present application, the first message can be a notification message that sends a notification to the receiving device, or it can be a request message that triggers the receiving device to perform business processing. In the case where the first message is a notification message, the message body carries a notification message / notification information, and the notification message / notification information can be used to notify the receiving device to perform business processing, but the receiving device does not return the execution result to the sending device. In the case where the first message is a request message, the message body carries a request message / request information, and the request message / request information can be used to request the receiving device to perform business processing; after the receiving device performs the business processing, the execution result needs to be sent to the sending device. The embodiment of the present application does not specifically limit the type of the first message.

[0084] In the present application, the implementation method of S110 includes: the first sending device sends the first message to the proxy server through the communication link between the first sending device and the proxy server.

[0085] S120: The proxy server receives the first message, and converts the first message into a second message.

[0086] In the present application, the format of the second message is the same as that of the first message. The second message may also include a message header, a message body and the source address of the first message. The message header of the second message may include a five-tuple of information. The five-tuple information of the second message includes: the source address of the second message, the destination address, the protocol version number, the port number of the source address of the second message and the port number of the destination address; the message body of the second message includes: the message body of the first message is the same; wherein, the message body of the second message or the message header of the second message also includes the source address of the first message; thus, the second message includes: the message body of the first message, the source address of the second message and the source address of the first message.

[0087] In the present application, the source address of the second message is used to indicate the public address of the proxy server, and the source addresses of the messages sent by different sending devices obtained after conversion by the proxy server are all the public address.

[0088] Specifically, the source address of the second message, i.e., the shared address, can be the IP address of the proxy server, or a combination of the IP address of the proxy server and the port number of the target port in the proxy server. The target port is the port through which the proxy server subsequently sends the second message to the load balancer; the specific embodiment of the present application does not limit the specific form of the above-mentioned public address.

[0089] The source address of the first message in the second message is carried in the target field in the second message, and the target field is a reserved field (such as a "reserve" field) or a newly added field in the second message. The source address of the first message may be added to the second message by the proxy server, or may be the source address of the first message backed up in the first message by the first sending device before sending the first message. Specifically, the embodiment of the present application does not limit the source of the source address of the first message in the second message.

[0090] In the case where the source address of the first message in the second message is added to the second message by the proxy server, the specific implementation of S120 refers to S120A in the following embodiment, which will not be described again here.

[0091] When the source address of the first message in the second message is the source address of the first message that the first sending device backed up in the first message before sending the first message, the specific implementation method of S120 refers to S230 in the following embodiment and is not repeated here.

[0092] S130. The load balancer receives a second message sent by the proxy server, and based on the source address of the first message included in the second message, determines a first receiving device from multiple receiving devices; and sends the second message to the first receiving device.

[0093] In one implementation, S130 is implemented as follows: Figure 4 As shown, including: S130A-S130D.

[0094] S130A: The load balancer receives a second message sent by the proxy server.

[0095] In the present application, the implementation method of S130A includes: the load balancer receives the second message sent by the proxy server through the communication link (referred to as: the first communication link) between the load balancer and the proxy server; accordingly, after the above S120, the proxy server sends the second message to the load balancer through the first communication link.

[0096] S130B. The load balancer obtains the source address of the first message from the second message.

[0097] The implementation method of S130B in the present application includes: the load balancer obtains the source address of the first message from the target field in the second message by parsing the second message.

[0098] S130C: The load balancer determines a first receiving device from multiple receiving devices based on a hash value of the source address of the first message.

[0099] The implementation method of S130C of the present application includes: the load balancer determines the hash value of the source address of the first message; then, based on the hash value and the number of multiple receiving devices, a modulo operation is performed to obtain a modulo result; finally, the receiving device whose device identifier among the multiple receiving devices corresponds to the modulo result is determined as the first receiving device.

[0100] The receiving device whose device identifier corresponds to the modulo result among the multiple receiving devices in the present application can be a receiving device whose device identifier is equal to the modulo result, or it can be the interval where the modulo result to which the device identifier belongs is located. The specific embodiment of the present application does not limit the correspondence between the device identifier and the modulo result.

[0101] For example, assuming that the hash value of the source address of the first message is 610529590177173682324, Figure 1 In the case where the message transmission system shown includes 7 receiving devices, then, based on 610529590177173682324 modulo 7, the modulo result obtained is 2. Then, the load balancer determines the receiving device whose device identifier (or device number) is equal to the modulo result 2 among the 7 receiving devices as the first receiving device.

[0102] Optionally, when the device identifier in the present application is a string or non-data, S130 also includes converting the device identifier into a device number based on a preset algorithm. The preset algorithm can be a remainder algorithm or a modulus algorithm, and the present embodiment does not specifically limit the preset algorithm.

[0103] S130D: The load balancer sends the second message to the first receiving device.

[0104] In the present application, the implementation method of S130D includes: the load balancer sends a second message to the first receiving device based on the communication link between the load balancer and the first receiving device (referred to as: second communication link); accordingly, the first receiving device receives the second message sent by the load balancer through the second communication link.

[0105] The load balancer in the embodiment of the present application performs a modulo operation based on the hash value of the source address of the first message and the number of multiple receiving devices to obtain a modulo result; and determines the receiving device whose device identifier corresponds to the modulo result among the multiple receiving devices as the first receiving device. Since the hash value of the source address of each sending device is fixed, the modulo result obtained by performing a modulo operation based on the hash value and the number of multiple receiving devices is also fixed; then, each message sent by each sending device is diverted to the same receiving device each time; thereby solving the problem that when the message sent by the same sending device is diverted to different receiving devices, the authentication information of the sending device does not exist in other receiving devices among the multiple receiving devices except the receiving device that processes the authentication message of the sending device, which causes other receiving devices to be unable to process the message sent by the sending device, thereby improving the stability of the message transmission system.

[0106] In another implementation, when there are a large number of receiving devices, in order to improve the efficiency of determining the first receiving device, the multiple receiving devices can be divided into different receiving groups, that is, the multiple receiving devices include receiving devices in different receiving groups, and the multiple receiving devices are devices in different receiving groups, and each receiving group includes at least one receiving device. In this scenario, the implementation method of S130 of the present application includes: based on the bandwidth level of the second message, determining the target receiving group corresponding to the bandwidth level of the second message from different receiving groups; then, based on the source address of the first message, determining the first receiving device from the receiving devices included in the target receiving group; for the specific implementation, refer to S310-S360 below, which will not be repeated here.

[0107] The embodiment of the present application provides a message transmission method, which converts a first message sent by a first sending device received by a proxy server into a second message including a message body of the first message, a source address of the second message and the source address of the first message, so that the load balancer determines the first receiving device from multiple receiving devices based on the source address of the first message included in the second message, and sends the second message to the first receiving device. Although the source address of the second message is used to indicate the public address of the proxy server, the source address of the first message included in the second message is used to point to the first sending device; since the source addresses of the first messages sent by different sending devices are different, the load balancer determines the first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0108] In addition, since the source addresses of the first messages sent by different sending devices are different, the load balancer will not divert the messages sent by different sending devices to the same receiving device when performing load diversion based on the source address of the first message, thereby improving the load balancing of the receiving device.

[0109] In the case where the proxy server adds the source address of the first message to the second message, based on Figure 3 or Figure 4 ,like Figure 5 The implementation method of S120 in the present application includes: S120A.

[0110] S120A: The proxy server replaces the source address of the first message in the source address field of the first message with the public address, and adds the source address of the first message to the target field in the first message to obtain a second message.

[0111] In the present application, the source address field of a message is a field used to carry the source address in the five-tuple information of the message; that is, the source address of the first message is carried in the source address field in the first message.

[0112] In the present application, the target field is a reserved field or a newly added field in the first message; wherein, the target field can be located in the message body of the first message or in the message header of the first message; the specific embodiment of the present application does not limit the position of the target field in the first message.

[0113] The second message obtained by S120A has the same format as the first message. The second message may also include a message header, a message body and the source address of the first message. The message header of the second message may include five-tuple information. The five-tuple information of the second message includes: the source address of the second message, the destination address, the protocol version number, the port number of the source address of the second message and the port number of the destination address.

[0114] The message body of the second message includes: the message body of the first message is the same; the source address of the second message is the public address carried in the source address field of the first message; the destination address, protocol version number, port number of the source address of the second message and the port number of the destination address in the five-tuple information of the second message are the same as the destination address, protocol version number, port number of the source address and the port number of the destination address in the five-tuple information of the first message.

[0115] The location of the target field in the second message that carries the source address of the first message may be in the message header of the second message or in the second message body; the specific embodiment of the present application does not limit the location of the target field.

[0116] Exemplarily, assume that the source address field is the "IP" field, and the target field is the "reserve" field; and assume that the source address of the first message is address A; and the public address is address B. Then, the proxy server replaces the field value of the "IP" field in the first message from address A to address B; and sets the field value of the "reserve" field in the first message to address A, thereby obtaining the updated first message, i.e., the second message in the present application.

[0117] In an embodiment of the present application, a proxy server is used to replace the source address of the first message in the source address field of the first message with a public address, and the source address of the first message is added to the target field in the first message to obtain a second message; since the source addresses of the first messages sent by different sending devices are different, the subsequent load balancer determines the above-mentioned first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0118] based on Figure 3 or Figure 4 , the present application embodiment provides a specific implementation method, such as Figure 6 The method shown includes: S210-S260.

[0119] S210. The first sending device adds a source address of the first message in a reserved field or a newly added field in the first message.

[0120] It should be understood that before the first sending device executes S210, the source address field in the first message carries the source address of the first message; so after the first sending device adds the source address of the first message in the reserved field or the newly added field (i.e., the target field) in the first message, the source address field and the target field in the added first message both carry the source address of the first message.

[0121] The target field may be a field in the message body of the first message, or a field in the message header of the first message; specifically, the embodiment of the present application does not limit the position of the target field in the first message.

[0122] The implementation method of the above S210 is similar to the implementation method of adding the source address of the first message to the target field in the first message in S120A. For the specific description of S210, please refer to the above related description of S120A, which will not be repeated here.

[0123] S220. The first sending device sends a first message to the proxy server.

[0124] The implementation method of the above S220 is consistent with the implementation method of S110. For the specific description of S220, please refer to the above related description of S110, which will not be repeated here.

[0125] S230. The proxy server replaces the source address of the first message in the source address field of the first message with the public address to obtain a second message.

[0126] It should be understood that the source address field and the target field in the first message received by the proxy server both carry the source address of the first message; so after the proxy server replaces the source address of the first message in the source address field in the first message with the public address, the target field in the updated first message (i.e., the second message) also carries the source address of the first message; then, the second message includes the source address of the first message.

[0127] The implementation method of the above S230 is consistent with the implementation method in which the proxy server in S120A replaces the source address of the first message in the source address field of the first message with a public address. For the specific description of S230, please refer to the above description of S120A, which will not be repeated here.

[0128] S240: The load balancer receives a second message sent by the proxy server.

[0129] S250. The load balancer determines a first receiving device from a plurality of receiving devices based on the source address of the first message included in the second message.

[0130] S260. The load balancer sends the second message to the first receiving device.

[0131] The implementation method of the above S240 is consistent with the implementation method of S130. For the specific description of S240, please refer to the above related description of S130, which will not be repeated here.

[0132] In an embodiment of the present application, a first sending device adds the source address of a first message to a reserved field or a newly added field in the first message, and replaces the source address of the first message in the source address field of the first message with a public address based on a proxy server to obtain a second message. Since the source address of the first message exists in the reserved field or the newly added field in the second message, and the source addresses of the first messages sent by different sending devices are different, the subsequent load balancer determines the above-mentioned first receiving device based on the source address of the first message, and sends the second message to the first receiving device, thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0133] exist Figure 1The multiple receiving devices in the message transmission system shown are receiving devices in different receiving groups (ie, the multiple receiving devices are receiving devices in different receiving groups), and each receiving group includes at least one receiving device. Figure 3 , Figure 5 to Figure 6 The implementation method of S130 of the present application is as follows Figure 7 As shown, it also includes: S310-S360.

[0134] S310. The load balancer receives a second message sent by the proxy server.

[0135] S320. The load balancer obtains the source address of the first message from the second message.

[0136] The implementation method of the above S310-S320 is consistent with the implementation method of S130A-S130B. For the specific description of S310-S320, please refer to the above related description of S130A-S130B, which will not be repeated here.

[0137] S330: The load balancer obtains the bandwidth level of the second message.

[0138] In the present application, the bandwidth level of a message is used to indicate the bandwidth size of the message. For example, the bandwidth level of a second message is used to indicate the bandwidth size of the second message.

[0139] Specifically, the bandwidth level of the message can be directly the bandwidth size of the message, or it can be a processing result obtained after processing the bandwidth size of the message based on a preset algorithm. The embodiment of the present application does not specifically limit the relationship between the bandwidth level and the bandwidth size.

[0140] It should be understood that in the present application, the second message is obtained by replacing the source address of the first message in the source address field of the first message with a public address (ie, converting), so the bandwidth level of the second message is the same as the bandwidth level of the first message.

[0141] In the present application, the bandwidth level of the message may be preset or determined based on the bandwidth size of the message. The specific embodiment of the present application does not limit the method for determining the bandwidth level of the message.

[0142] In the case where the bandwidth level of the second message is preset, the implementation method of S330 includes: the load balancer obtains the bandwidth level of the second message from the second message; wherein the bandwidth level of the second message may be the preset bandwidth level of the first message added by the first sending device in a designated field (such as the "bw" field) in the first message before the first sending device sends the first message; or may be the preset bandwidth level of the first message added by the proxy server in a designated field in the first message during the execution of S120.

[0143] It should be understood that in the implementation of S330 above, the user needs to pre-configure the bandwidth level for each service message or each message sent by the sending device, so that the sending device or the proxy server adds the pre-configured bandwidth level for the message in the message.

[0144] In the case of determining the bandwidth level of the second message based on the bandwidth size of the second message, the implementation method of S330 includes: the load balancer obtains the bandwidth size of the second message, and determines the bandwidth level corresponding to the bandwidth size of the second message in the correspondence between the bandwidth size and the bandwidth level as the bandwidth level of the second message.

[0145] S340. The load balancer determines a target receiving group corresponding to the bandwidth level of the second message from multiple receiving groups.

[0146] In the present application, different receiving groups correspond to different bandwidth levels; for example, when the above-mentioned multiple receiving groups include: a first receiving group and a second receiving group, the bandwidth level corresponding to the first receiving group is different from the bandwidth level corresponding to the second receiving group.

[0147] In the present application, each of the multiple receiving groups may correspond to a bandwidth level interval including multiple bandwidth levels (i.e., the receiving group corresponds to the bandwidth level interval), or each receiving group may correspond to one bandwidth level (i.e., the receiving group corresponds to the bandwidth level); the specific embodiments of the present application do not limit the correspondence between the receiving group and the bandwidth level.

[0148] When each receiving group corresponds to a bandwidth level interval, the implementation method of S340 includes: determining the receiving group corresponding to the bandwidth level interval to which the bandwidth level of the second message belongs as the target receiving group; the specific implementation method is shown in the following S341-S345 and will not be repeated here.

[0149] In the case that each receiving group corresponds to a bandwidth level, the implementation method of S340 includes: determining a receiving group among the multiple receiving groups whose corresponding bandwidth level is the same as the bandwidth level of the second message as a target receiving group.

[0150] Exemplarily, assume that the multiple receiving groups include: a first receiving group, a second receiving group and a third receiving group, wherein the bandwidth level corresponding to the first receiving group is bandwidth level one, the bandwidth level corresponding to the second receiving group is bandwidth level two, and the bandwidth level corresponding to the third receiving group is bandwidth level three; then, when the bandwidth level of the second message is bandwidth level one, the first receiving group is determined as the target receiving group; when the bandwidth level of the second message is bandwidth level two, the second receiving group is determined as the target receiving group; when the bandwidth level of the second message is bandwidth level three, the third receiving group is determined as the target receiving group.

[0151] The above-mentioned load balancer may execute S320 first and then execute S330-S340; or it may execute S330-S340 first and then execute S320. Specifically, the embodiment of the present application does not limit the execution order of S320 and S330-S340.

[0152] S350. The load balancer determines a first receiving device from receiving devices included in the target receiving group based on a hash value of the source address of the first message.

[0153] The implementation method of the above S350 is similar to the implementation method of S130C. For the specific description of S350, please refer to the above related description of S130C, which will not be repeated here.

[0154] S360. The load balancer sends the second message to the first receiving device.

[0155] The implementation method of the above S360 is consistent with the implementation method of S130D. For the specific description of S360, please refer to the above related description of S130D, which will not be repeated here.

[0156] The embodiment of the present application divides multiple receiving devices into different receiving groups according to the bandwidth size (i.e., bandwidth level) of the messages they process; then, after the load balancer receives the second message, it determines the target receiving group corresponding to the bandwidth level of the second message from the different receiving groups; then, based on the hash value of the source address of the first message, it determines the first receiving device from the target receiving group. This avoids the problem of downtime of the receiving device caused by diverting messages with a higher bandwidth level to a receiving device with fewer resources, thereby improving the stability of the receiving device.

[0157] In addition, since the bandwidth levels corresponding to the multiple receiving groups are different, the target receiving groups determined by the messages of different bandwidth levels (such as the second message) are different. After determining the target receiving group, the load balancer determines the first receiving device from the receiving devices included in the target receiving group based on the source address of the sending device indicating the sending of the message (such as the source address of the first message), and sends the message to the first receiving device; thereby realizing the function of message transmission based on the load balancer in the presence of a proxy server.

[0158] For ease of description, the embodiment of the present application is described by taking a case where multiple receiving groups include: a first receiving group, a second receiving group, and a third receiving group as an example, and no further details will be given later.

[0159] In the case where each receiving group corresponds to a bandwidth level interval, combined with Figure 7 , the implementation of S340 is as follows Figure 8 Shown include: S341-S345.

[0160] S341. The load balancer determines whether the bandwidth level of the second message is lower than the first preset level.

[0161] Exemplarily, assuming that the first preset level is bandwidth level three; then, when the bandwidth level of the second message is bandwidth level two or bandwidth level one, the bandwidth level of the second message is lower than the first preset level; when the bandwidth level of the second message is bandwidth level four, the bandwidth level of the second message is higher than the first preset level.

[0162] When the bandwidth level of the second message is lower than the first preset level, the load balancer executes the following S342.

[0163] When the bandwidth level of the second message is higher than the first preset level, the load balancer executes the following S343.

[0164] When the bandwidth level of the second message is equal to the first preset level, the load balancer can execute the following S342 or the following S343. Specifically, the embodiment of the present application does not limit the action performed by the load balancer when the bandwidth level of the second message is equal to the first preset level.

[0165] S342. The load balancer determines the first receiving group as the target receiving group.

[0166] Exemplarily, based on the example in S341, assume that the first receiving group includes: receiving device 1, receiving device 2, and receiving device 3; then, when the bandwidth level of the second message is bandwidth level 2 or bandwidth level 1, the load balancer determines the first receiving group as the target receiving group, which includes: receiving device 1, receiving device 2, and receiving device 3.

[0167] S343: The load balancer determines whether the bandwidth level of the second message is lower than a second preset level.

[0168] Exemplarily, assume that the second preset level is bandwidth level six; then, when the bandwidth level of the second message is bandwidth level five, the bandwidth level of the second message is lower than the second preset level; when the bandwidth level of the second message is bandwidth level eight, the bandwidth level of the second message is higher than the second preset level.

[0169] When the bandwidth level of the second message is lower than the second preset level, the load balancer executes the following S344.

[0170] When the bandwidth level of the second message is higher than the second preset level, the load balancer executes the following S345.

[0171] When the bandwidth level of the second message is equal to the second preset level, the load balancer can execute the following S344 or the following S345. Specifically, the embodiment of the present application does not limit the action performed by the load balancer when the bandwidth level of the second message is equal to the second preset level.

[0172] S344. The load balancer determines the first receiving group and the second receiving group as target receiving groups.

[0173] Exemplarily, based on the example in S343, assume that the first receiving group includes: receiving device 1, receiving device 2 and receiving device 3; the second receiving group includes: receiving device 4, receiving device 5 and receiving device 6; then, when the bandwidth level of the second message is bandwidth level five, the load balancer determines the first receiving group and the second receiving group as target receiving groups; wherein, the target receiving group includes: receiving device 1 to receiving device 6.

[0174] S345. The load balancer determines the first receiving group, the second receiving group, and the third receiving group as target receiving groups.

[0175] Exemplarily, based on the example in S343, assume that the first receiving group includes: receiving device 1 to receiving device 3, the second receiving group includes: receiving device 4 to receiving device 6, and the third receiving group includes: receiving device 7 to receiving device 9; then, when the bandwidth level of the second message is bandwidth level eight, the load balancer determines the first receiving group, the second receiving group and the third receiving group as target receiving groups; wherein, the target receiving group includes: receiving device 1 to receiving device 9.

[0176] In the embodiment of the present application, the above-mentioned multiple receiving groups include the first receiving group to the third receiving group. When the bandwidth level of the second message is lower than the first preset level, the first receiving group is determined as the target receiving group; when the bandwidth level of the second message is higher than the first preset level and the bandwidth level of the second message is lower than the second preset level, the first receiving group and the second receiving group are determined as the target receiving groups; when the bandwidth level of the second message is higher than the second preset level, the first receiving group, the second receiving group and the third receiving group are determined as the target receiving groups. It can be seen that the higher the bandwidth level of the second message, the more receiving devices are included in the target receiving group determined by the load balancer; that is, the higher the bandwidth level of the second message, the more options are determined for determining the first receiving device; thereby avoiding the problem that the receiving device processing the high-bandwidth message cannot use other receiving devices to process the high-bandwidth message when the available resources are insufficient, thereby improving the load balancing of the receiving device.

[0177] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method.
