[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0048] In the prior art: As shown in Figure 1(a), ClusterIP is only accessible to workloads within the k8s cluster. By deploying a forwarding program on the computing node, the requests sent by the workload on the computing node are forwarded to the workloads on other nodes. As shown in Figure 2(a): ClusterIP is only accessible within the cluster.

[0049] As shown in Figure 1(b): The NodePort method also deploys a forwarding program on the computing node. The workload (request end) outside the k8s cluster can access the computing node IP and the assigned port where the workload is located, and the forwarding program on the computing node forwards the access request to the workload in the cluster. As shown in Figure 2(b): With the NodePort method, both request and response data need to pass through the computing node. For requests that require a large amount of data transmission, it will affect the bandwidth of the computing node and consume the computing performance of the computing point. At the same time, it is necessary to introduce additional high-availability mechanisms, such as switching DNS using the service active health check detection mechanism, etc. The horizontal expansion capability is not good, and TCP ports need to be allocated from the computing node. Due to the number of ports, the number of services supported is limited.

[0050] As shown in Figure 1(c): Load balancer (LB) refers to relying on traditional load balancing equipment to assign a service IP and port to the service in the k8s cluster. The client's request first reaches the load balancer, which forwards the request to the workload in the k8s cluster. As shown in Figure 2(c): With load balancing, both requests and responses outside the cluster and within the cluster need to be transferred through it, which has a relatively high latency. Due to the large traffic between east-west workloads, a load balancing service cluster with greater processing power is required, which is relatively expensive.

[0051] To address the deficiencies in the prior art, the methods in the following embodiments may be used.

[0052] The present application embodiment provides an information processing method, wherein the information processing method is applied to a first information processing device. Figure 3 A flow chart of an information processing method provided in an embodiment of the present application, such as Figure 3 As shown, the information processing method may include:

[0053] S101. Upon receiving a first data access request transmitted by a second information processing device, parse the first data access request to obtain a request forwarding address and a first address; the request forwarding address is the address of the second information processing device.

[0054] An information processing method provided in an embodiment of the present application is suitable for a scenario in which load balancing is performed on data access requests in K8s.

[0055] In the embodiments of the present application, the first information processing device can be implemented in various forms. For example, the first information processing device described in the present application may include devices such as mobile phones, cameras, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and devices such as digital TVs, desktop computers, and servers.

[0056] In an embodiment of the present application, the first information processing device is a computing node within K8s, the second information processing device can be a client (i.e., a computing node outside the K8s cluster), and the second information processing device can also be a computing node within K8s (i.e., other computing nodes except the first information processing device); the specific second information processing device can be determined according to actual conditions, and the embodiment of the present application does not limit this.

[0057] In an embodiment of the present application, if the second information processing device is a computing node other than the first information processing device in K8s, the first data access request may be a request generated by the second information processing device; or the first data access request may be a request to forward the second data access request generated by the client to the first information processing device through the second information processing device.

[0058] In the embodiment of the present application, the first information processing device includes an address translation module (ReqMux-NAT-Agent) for parsing the first data access request to obtain the first address and the request forwarding address.

[0059] In the embodiment of the present application, if the first data access request is a request to forward the second data access request generated by the client to the first information processing device through the second information processing device, the first address is the address of the client.

[0060] In an embodiment of the present application, if the first data access request is a request generated by the second information processing device, then upon receiving the first data access request, the first information processing device parses the first data access request, and the obtained request forwarding address is the same as the first address, both of which are the address of the second information processing device.

[0061] It should be noted that the first address can be an Internet Protocol (IP) / Transmission Control Protocol (TCP) address, or other addresses; the specific first address can be determined based on actual conditions, and the embodiments of the present application do not limit this.

[0062] It should be noted that the request forwarding address may be an IP / TCP address; the request forwarding address may also be other addresses; the specific request forwarding address may be determined based on actual conditions, and the embodiments of the present application do not limit this.

[0063] In an embodiment of the present application, the address conversion module is deployed in each computing node in the K8s cluster.

[0064] In the embodiment of the present application, the first data access request may be an access request for any data; the specific first data access request may be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0065] In the embodiment of the present application, the manner in which the first information processing device parses the first data access request is an existing technical manner; the specific manner can be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0066] In an embodiment of the present application, the process in which the first information processing device, upon receiving a first data access request transmitted by a second information processing device, parses the first data access request to obtain a first address and a request forwarding address includes: the first information processing device, upon receiving the first data access request and the first data access request carries a preset identifier, parses the first data access request to obtain the first address and the request forwarding address.

[0067] In the embodiment of the present application, the preset identifier carried in the first data access request may be: the identifier of the preset identifier field in the IP option in the first data access request is the preset identifier.

[0068] It should be noted that the preset identifier may be an unallocated identifier, and the preset identifier complies with the Request for Comments (RFC) regulations.

[0069] Exemplarily, the preset identifier may be a code, or may be other identifiers; the specific preset identifier may be determined according to actual conditions, and the embodiments of the present application do not limit this.

[0070] In the embodiment of the present application, the first data access request includes an IP header and an IP message, and the destination address of the request is recorded in the IP option in the IP message (for the first data access request sent to the second information processing device, the destination address is the address of the second information processing device). Specifically, the IP option consists of three fields: code, length, and value, wherein the information in value is the request forwarding address, the information in length is the length value of the information in Value, and code is a preset identifier.

[0071] In an embodiment of the present application, after the first information processing device parses the first data access request and obtains the first address and the request forwarding address, the first information processing device also establishes a first corresponding relationship between the first address, the second address and the request forwarding address.

[0072] It should be noted that the second address is the device that actually processes the first data access request and generates corresponding response information, that is, the address of the first information processing device.

[0073] It should be noted that the first address includes the source IP and source port (Port) of the client; the second address includes the destination IP and destination port (Port) of the first information processing device.

[0074] In an embodiment of the present application, the first information processing device also obtains a transport layer protocol, such as a Transmission Control Protocol (TCP) / User Datagram Protocol (UDP), from the first data access request.

[0075] In an embodiment of the present application, the first information processing device uses the first address, the second address and the transport layer protocol as keys and the request forwarding address as the corresponding value to obtain a kv key-value pair, that is, a first corresponding relationship.

[0076] S102: Generate corresponding response information according to the first data access request.

[0077] In the embodiment of the present application, after the first information processing device parses the first data access request and obtains the request forwarding address and the first address, the first information processing device generates corresponding response information according to the first data access request.

[0078] In the embodiment of the present application, the process of the first information processing device generating corresponding response information according to the first data access request is a prior art, and the embodiment of the present application does not limit this.

[0079] S103, modify the second address in the response information to the request forwarding address, and obtain updated response information; the second address is the address of the first information processing device.

[0080] In an embodiment of the present application, after the first information processing device generates corresponding response information according to the first data access request, the first information processing device modifies the second address in the response information to the request forwarding address to obtain updated response information.

[0081] In an embodiment of the present application, the first information processing device may delete the second address in the response information and write the requested forwarding address in the position of the second address, thereby obtaining updated response information; the specific implementation method of the first information processing device modifying the second address in the response information to the requested forwarding address to obtain the updated response information can be determined according to actual conditions, and the embodiment of the present application does not limit this.

[0082] In an embodiment of the present application, the process in which the first information processing device modifies the second address in the response information to the request forwarding address to obtain the updated response information includes the first information processing device obtaining the destination sending address of the response information, the second address carried in the response information, and the request forwarding address; establishing a second correspondence between the destination sending address, the second address, and the request forwarding address; and when the first correspondence matches the second correspondence, modifying the second address in the response information to the request forwarding address to obtain the updated response information.

[0083] In the embodiment of the present application, the generated response information carries the second address.

[0084] In an embodiment of the present application, the manner in which the first information processing device establishes a second correspondence between the destination sending address, the second address and the request forwarding address is the same as the manner in which the information processing device establishes a first correspondence between the first address, the second address and the request forwarding address.

[0085] In an embodiment of the present application, when the first information processing device determines that the request forwarding address in the first relationship is the same as the request forwarding address in the second relationship, the second address in the first relationship is the same as the second address in the second relationship, and the first address in the first relationship is the same as the destination sending address in the second relationship, the first information processing device determines that the first corresponding relationship matches the second corresponding relationship.

[0086] S104: Transmit updated response information to the client corresponding to the first address.

[0087] In an embodiment of the present application, the first information processing device modifies the second address in the response information to the request forwarding address, and after obtaining the updated response information, the first information processing device transmits the updated response information to the client corresponding to the first address.

[0088] In an embodiment of the present application, ReqMux-NAT-Agent is used to parse an IP message sent to a first information processing device (a first data access request is composed of multiple IP messages). If a code field is included in the IP option of the IP message, the field is parsed to obtain the request forwarding address before being modified by the request distribution module (ReqMux) in the second information processing device, and a record is generated. The key of the record is the five-tuple information extracted from the IP message (source IP, source port, destination IP, destination port, transport layer protocol), and the value of the record is the request forwarding address, thereby obtaining a first corresponding relationship. For the IP message sent by the first information processing device, the five-tuple information is also extracted according to the above method to obtain a second corresponding relationship, and it is checked whether there is a record (to determine whether the first corresponding relationship matches the second corresponding relationship). If so (the first corresponding relationship matches the second corresponding relationship), the second address in the response information is modified to the request forwarding address to obtain an updated response information.

[0089] For example, Figure 4 As shown: ReqMux-NAT-Agent is divided into two parts, such as Figure 4 As shown in ②, for the message sent to the first information processing device, the program logic is connected in series to the message processing link (LocalIN) of the operating system protocol stack for the message sent to the first information processing device through the HOOK mechanism of the operating system. By setting the priority, the address conversion (DNAT, destination address conversion) program is executed preferentially for the message sent to the first information processing device. For example, the Linux system uses the netfilter framework to register the hook function on the PREROUTING chain to parse the incoming IP message (parse the received message or the generated message). If the IP option of the IP message includes a code field, the field is parsed to obtain the request forwarding address before being modified by the ReqMux in the second information processing device, and a record is generated. The key of the record is the five-tuple information (source IP, source port, destination IP, destination port, transport layer protocol) extracted from the IP message, and the value of the record is the request forwarding address, thereby obtaining the first corresponding relationship. The other part is for the message sent by the first information processing device, such as Figure 4As shown in ③, through the HOOK mechanism of the operating system, the program logic is connected in series to the message processing link (LocalOut) of the operating system protocol stack for the first information processing device. By setting the priority, this program is executed preferentially for the message sent to the first information processing device. For example, the Linux system uses the netfilter framework to register the hook function on the POSTROUTING chain, extract the five-tuple information, obtain the second correspondence, and search for the information saved in ② (determine whether the first correspondence matches the second correspondence). If found (that is, the first correspondence matches the second correspondence), the second address in the response information is modified to the request forwarding address (SNAT, source address translation) to obtain the updated response information.

[0090] It can be understood that the first information processing device obtains the first address and request forwarding address of the client by parsing the first data access request, and modifies the second address in the response information to the request forwarding address, so that the client can believe that the updated response information is sent by the second information processing device based on the request forwarding address, and can directly identify the updated response information, thereby eliminating the need to use the second information processing device to transmit the response information to the client along the reverse path of the data access request. When the number of data access requests and response information is large, the bandwidth of the information processing device is reduced, that is, the bandwidth of the computing node is reduced, and at the same time, the processing speed of the data access request is improved.

[0091] The embodiment of the present application provides an information processing method, wherein the information processing method is applied to a second information processing device. Figure 5 A flow chart of an information processing method provided in an embodiment of the present application, such as Figure 5 As shown, the information processing method may include:

[0092] S201. Upon receiving a second data access request transmitted by a client, obtain a request forwarding address from the second data access request.

[0093] An information processing method provided in an embodiment of the present application is suitable for a scenario in which load balancing is performed on data access requests in K8s.

[0094] In the embodiments of the present application, the second information processing device can be implemented in various forms. For example, the second information processing device described in the present application may include devices such as mobile phones, cameras, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and devices such as digital TVs, desktop computers, and servers.

[0095] In an embodiment of the present application, the second information processing device carries a request distribution module (ReqMux) for processing a second data access request transmitted by the client to the second information processing device or a second data access request generated by the second information processing device, obtains a first data access request, and sends it to the first information processing device.

[0096] In an embodiment of the present application, ReqMux is deployed in each computing node in the K8s cluster.

[0097] In an embodiment of the present application, the client is a computing node outside the K8s cluster, and the second information processing device is other computing nodes in the K8s cluster except the first information processing device.

[0098] In an embodiment of the present application, if the second data access request is a request generated by a second information processing device, then when the second information processing device generates the second data access request, the second information processing device determines the first information processing device based on the request forwarding address (that is, the address of the second information processing device, and the second data access request generated by the second information processing device carries the request forwarding address) and obtains the second address of the first information processing device; adjusts the second data access request using the request forwarding address and the second address to obtain the first data access request; and sends the first data access request to the first information processing device.

[0099] In the embodiment of the present application, the second data access request carries a request forwarding address and a first address of the client, wherein the first address is the address of the client.

[0100] It should be noted that the first address may be an IP / TCP address, or other addresses; the specific first address may be determined based on actual conditions, and the embodiments of the present application do not limit this.

[0101] It should be noted that the request forwarding address may be an IP / TCP address; the request forwarding address may also be other addresses; the specific request forwarding address may be determined based on actual conditions, and the embodiments of the present application do not limit this.

[0102] It should be noted that the second address may be an IP / TCP address; the second address may also be other addresses; the specific second address may be determined based on actual conditions, and the embodiments of the present application do not limit this.

[0103] In the embodiment of the present application, the second data access request may be an access request for any data; the specific second data access request may be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0104] In an embodiment of the present application, when the second information processing device receives the second data access request transmitted by the client, before obtaining the request forwarding address from the second data access request, the second information processing device will also use the dynamic routing protocol to broadcast the request forwarding address; or call the cluster external interface to register the request forwarding address.

[0105] In an embodiment of the present application, the second information processing device includes a routing module (RouteAgent) for broadcasting a request forwarding address using a dynamic routing protocol; or calling a cluster external interface to register a request forwarding address so that the client can transmit a second data access request to the second information processing device according to the request forwarding address.

[0106] In an embodiment of the present application, the second information processing device may also broadcast a request forwarding address to the client in other ways; the specific way in which the second information processing device broadcasts a request forwarding address to the client can be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0107] It should be noted that the routing module is deployed in some computing nodes within the K8s cluster, such as the routing forwarding module is deployed in the second information processing device within the K8s cluster.

[0108] S202: Determine the first information processing device according to the request forwarding address, and obtain the second address of the first information processing device.

[0109] In an embodiment of the present application, after the second information processing device obtains the request forwarding address from the second data access request, the second information processing device determines the first information processing device based on the request forwarding address and obtains the second address of the first information processing device.

[0110] In the embodiment of the present application, the method in which the second information processing device determines the first information processing device according to the request forwarding address is an existing technical method; the specific embodiment of the present application does not limit this.

[0111] S203: Use the request forwarding address and the second address to adjust the second data access request to obtain the first data access request.

[0112] In an embodiment of the present application, after the second information processing device determines the first information processing device based on the request forwarding address and obtains the second address of the first information processing device, the second information processing device uses the request forwarding address and the second address to adjust the second data access request to obtain the first data access request.

[0113] In an embodiment of the present application, the process in which the second information processing device uses the request forwarding address and the second address to adjust the second data access request to obtain the first data access request includes: the second information processing device determines the first message header based on the second address; uses the first message header to modify the second message header in the second data access request to obtain the third data access request; adds the request forwarding address to the third data access request to obtain the first data access request.

[0114] In the embodiment of the present application, if the second address is an IP / TCP address, the first message header can be determined according to the format of the message header of the message in the second data access request and the IP / TCP address.

[0115] In an embodiment of the present application, the process in which the second information processing device adds a request forwarding address in the third data access request to obtain the first data access request includes: the second information processing device adds a request forwarding address in the data message of the third data access request to obtain the first data access request.

[0116] In an embodiment of the present application, the second data access request includes at least one message, each of the at least one message includes an IP header and an IP message, and the IP option in the IP message consists of three fields: code, length and value, wherein the value of the value field is the requested forwarding address, the value of the length field is the length value of the information in the Value; code is a preset identifier.

[0117] In an embodiment of the present application, the second information processing device adds a request forwarding address to the data message of the third data access request to obtain the first data access request. The second information processing device can set the value of the value field of the data message (IP message) to the request forwarding address, and use the value of the length field to identify the information length of the request forwarding address information; and set the code to obtain the first data access request.

[0118] S204: Send a first data access request to the first information processing device.

[0119] In an embodiment of the present application, the second information processing device adjusts the second data access request using the request forwarding address and the second address, and after obtaining the first data access request, the second information processing device sends the first data access request to the first information processing device.

[0120] In an embodiment of the present application, ReqMux is used to receive a second data access request and match the request forwarding address (ip, port) of the request. After matching, the first information processing device (back-end server) is determined based on the request forwarding address, and the message header (IP header and TCP header) of the second data access request is modified. The corresponding IP and TCP port of the request forwarding address are modified to the IP and service port of the first information processing device, and the destination request address (i.e., the address of the first information processing device) is recorded in the IP option of the IP message of the second data access request.

[0121] Exemplarily, ReqMux can connect the program logic in series to the message processing link sent to the second information processing device by the operating system protocol stack through the HOOK mechanism of the operating system. By setting the priority, the request dispatching program is executed preferentially for the message sent to the second information processing device. For example, the Linux system uses the netfilter framework to register the hook function on the LOCAL_IN chain. For all messages sent to the second information processing device, obtain the request forwarding address (IP and port number) of the message, search the exposed service list through the IP and port number, and if found, select a backend server (workload, i.e., the first information processing device) through a consistent hashing algorithm (such as the maglev consistent hashing algorithm), modify the message header of the second data access request, modify the corresponding IP and TCP port of the request forwarding address to the IP and service port (DNAT) of the first information processing device, and record the request forwarding address (ip, port) in the IP option of the IP message. The IP option consists of three fields: code, length, and value. The value of the value field is the request forwarding address, and the value of the length field is the length value of the information in the Value. The code is a preset identifier that complies with the IPv4 RFC and IPv6 RFC protocols. The preset identifier is a private code and does not conflict with other programs within the organization.

[0122] For example, Figure 6As shown: a client outside the cluster (workload: 10.1.2.3) transmits a second data access request to a second information processing device (computing node 1) in the K8s cluster; the second information processing device (ReqMux in) obtains a request forwarding address (172.1.2.1:80) from the second data access request; the first information processing device is determined according to the request forwarding address, and the second address of the first information processing device (192.168.1.3:8080) is obtained; the first message header is determined according to the second address; the second message header in the second data access request is modified using the first message header to obtain a third data access request; the request forwarding address is added to the third data access request to obtain the first data access request; and the first data access request is sent to the first information processing device. When the first information processing device (computing node 2) receives the first data access request transmitted by the second information processing device, the ReqMux-NAT-Agent in the second information processing device parses the first data access request to obtain the first address and the request forwarding address; generates corresponding response information according to the first data access request; ReqMux-NAT-Agent modifies the second address in the response information to the request forwarding address to obtain updated response information; and transmits the updated response information to the client corresponding to the first address (workload: 10.1.2.3).

[0123] For example, Figure 7 As shown: When the second information processing device (computing node 1) in the K8s cluster generates a second data access request, the second information processing device determines the first information processing device according to the request forwarding address (i.e., the address of the second information processing device), and obtains the second address of the first information processing device; adjusts the second data access request using the request forwarding address and the second address to obtain the first data access request; and sends the first data access request to the first information processing device. When the first information processing device (computing node 2) in the K8s cluster receives the first data access request transmitted by the second information processing device, the ReqMux-NAT-Agent in the second information processing device parses the first data access request to obtain the first address and the request forwarding address; at this time, the first address and the request forwarding address are the same, and the corresponding response information is generated according to the first data access request; the ReqMux-NAT-Agent modifies the second address in the response information to the request forwarding address to obtain the updated response information; and transmits the updated response information to the client corresponding to the first address (workload: 10.1.2.3).

[0124] It can be understood that, when the second information processing device receives the second data access request transmitted by the client, it adjusts the second data access request using the request forwarding address and the second address to obtain the first data access request, that is, adds the request forwarding address and the second address to the second data access request, so that the first information processing device can modify the second address in the response information to the request forwarding address, so that the client can believe that the updated response information is sent by the second information processing device based on the request forwarding address, and can directly identify the updated response information, thereby eliminating the need to use the second information processing device to transmit the response information to the client according to the reverse transmission path of the data access request. When the number of data access requests and response information is large, the bandwidth of the information processing device is reduced, that is, the bandwidth of the computing node is reduced, and the processing speed of the data access request is improved.

[0125] Based on the same inventive concept as the information processing method applied to the first information processing device, the embodiment of the present application provides a first information processing device 1 corresponding to an information processing method; Figure 8 A schematic diagram of a first information processing device provided in an embodiment of the present application is shown in FIG. 1 .

[0141] It can be understood that the first information processing device obtains the first address and request forwarding address of the client by parsing the first data access request, and modifies the second address in the response information to the request forwarding address, so that the client can believe that the updated response information is sent by the second information processing device based on the request forwarding address, and can directly identify the updated response information, thereby eliminating the need to use the second information processing device to transmit the response information to the client along the reverse path of the data access request. When the number of data access requests and response information is large, the bandwidth of the information processing device is reduced, that is, the bandwidth of the computing node is reduced, and at the same time, the processing speed of the data access request is improved.
