Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a service scheduling communication method, system, electronic device, and computer storage medium. Background Art

[0002] Currently, traditional communication service scheduling on the DPU is primarily performed in the following manner: When the DPU receives a request message from a first service to a second service, if it matches a pre-defined NAT rule, it replaces the second address (destination address) and second port number (destination port number) of the second service in the request message with the address and port number of the service scheduling engine. The five-tuple information (source address, source port number, destination address, destination port number, and protocol number) before and after the modification is recorded in the NAT session table. In this way, the request message from the first service is forwarded and processed by the service scheduling engine and then sent to the second service, thereby scheduling communication between the first and second services. After receiving the response from the service scheduling engine, the second address and second port number are restored by referring to the recorded NAT session table. Upon receiving the request message, it undergoes a pre-defined NAT rule match and a NAT session table match. Upon receiving the response, it also undergoes a NAT session table match. This increases message forwarding latency, increases memory usage due to storing the NAT session table, and reduces scheduling efficiency. Summary of the Invention

[0003] In view of this, an embodiment of the present application provides a service scheduling communication method, which can reduce message forwarding delay, reduce memory usage, and improve scheduling efficiency when scheduling communication between at least one service associated with the main device configured with a DPU.

[0004] A first aspect of the present disclosure provides a service scheduling communication method for a dedicated data processor coupled to a master device, wherein the service scheduling communication is communication between a first service and a second service, at least one of the first service and the second service being associated with the master device. The service scheduling communication method includes:

[0005] receiving a request message from the first service to the second service, the request message including the second address and the second port number of the second service;

[0006] Keeping the second address unchanged, changing the second port number to a fixed port number bound to a service scheduling engine dedicated to processing service scheduling in the dedicated data processor, and recording the second port number in the first data structure;

[0007] Sending the request message to a session module interfaced with the service scheduling engine, wherein the session module transmits the request message to a fixed port of the fixed port number bound to the service scheduling engine;

[0008] When the session module receives a response message from the service scheduling engine, the session module modifies the source port number of the response message based on the second port number in the first data structure.

[0009] In some embodiments of the present disclosure, before sending the request message to the session module connected to the service scheduling engine interface, and before the session module passes the request message to the fixed port service scheduling engine bound to the fixed port number of the service scheduling engine interface, the service scheduling communication method further includes:

[0010] Through the session module, the second port number is obtained from the first data structure and recorded in the session structure, so that after the session module receives the response data from the service scheduling engine, the second port number is obtained from the session structure and used to establish communication with the second port number of the second address, thereby generating the response message.

[0011] In some embodiments of the present disclosure, when the session module receives a response message from the service scheduling engine, modifying the source port number of the response message based on the second port number in the first data structure includes:

[0012] The second port number is taken out from the session structure, and the second port number is used as the source port number of the response message.

[0013] In some embodiments of the present disclosure, the first data structure includes a change flag field and a second port number field;

[0014] Said recording the second port number into the first data structure comprises: recording the second port number into the second port number field, and adding a change flag into the change flag field;

[0015] The method of obtaining the second port number from the first data structure and recording it in the session structure through the session module includes: obtaining the second port number from the second port number field and recording it in the session structure through the session module if the change mark field contains the change mark.

[0016] In some embodiments of the present disclosure, before the second address is kept unchanged and the second port number is changed to a fixed port number bound to a service scheduling engine dedicated to processing service scheduling in the dedicated data processor, the service scheduling communication method further includes:

[0017] Determine whether there is a redirection rule corresponding to the second address and the second port in the preset redirection rule table; if the redirection rule exists, change the second port number of the request message to a fixed port number bound to a service scheduling engine specifically used to process service scheduling in a dedicated data processor specified by the redirection rule.

[0018] In some embodiments of the present disclosure, sending the request message to a session module interfaced with the service scheduling engine further includes:

[0019] If the redirection rule exists, before searching the routing table for the request message, the modified request message is sent to the session module interfaced with the service scheduling engine.

[0020] In some embodiments of the present disclosure, sending the request message to a session module interfaced with the service scheduling engine further includes:

[0021] If the redirection rule does not exist, the routing table is searched according to the second address and the second port of the request message, and the request message is sent out or sent to a service scheduling engine in a dedicated data processor dedicated to processing service scheduling according to the routing table.

[0022] A second aspect of the present disclosure further provides a service scheduling communication system for a dedicated data processor coupled to a master device, wherein the service scheduling communication is communication between a first service and a second service, at least one of the first service and the second service being associated with the master device. The service scheduling communication system includes:

[0023] a request data receiving module, configured to receive a request message from the first service to the second service, the request message including the second address and the second port number of the second service;

[0024] a request data modification module, configured to keep the second address unchanged, change the second port number to a fixed port number bound to a service scheduling engine dedicated to processing service scheduling in the dedicated data processor, and record the second port number in a first data structure;

[0025] A request data sending module, configured to send the request message to a session module that interfaces with the service scheduling engine, wherein the session module transmits the request message to the fixed port number of the service scheduling engine interface and the fixed port number bound to the service scheduling engine;

[0026] A response data sending module is configured to modify the source port number of the response message based on the second port number in the first data structure after the session module receives the response message from the service scheduling engine.

[0027] A third aspect of the present disclosure further provides a dedicated data processor, characterized by comprising:

[0028] A memory and a processor, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the service scheduling communication method described in any one of the above embodiments is implemented.

[0029] The fourth aspect of the present disclosure further proposes a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the service scheduling communication method described in any one of the above embodiments are implemented.

[0030] In the embodiment of the present disclosure, when the DPU performs scheduling communication between the first service and the second service of the main device, only the fixed port of the service scheduling engine is allowed to process the scheduling communication, so the second address can be kept unchanged, and only the second port number is changed to the fixed port number bound to the service scheduling engine. Compared with the method in which the service scheduling engine may have multiple addresses and multiple port numbers processing scheduling communications, this method reduces the workload of changes. Since the service scheduling engine has only one fixed port to process scheduling communications, and the port number is unique, it is no longer necessary to maintain the NAT session table. It eliminates the load of NAT session table matching that the prior art has to go through when receiving a request message. At the same time, it simply records the second port number in the first data structure, so that when receiving the response of the service scheduling engine, it does not need to go through the NAT session table matching, but only needs to simply look up the second port. Therefore, the message forwarding delay is reduced, the memory usage is reduced, and the scheduling efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field should fall within the scope of protection of the embodiments of the present application.

[0040] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0041] The present disclosure aims to solve the problems of poor network message processing performance and excessive resource overhead in traditional scenarios where dedicated data processors are used to offload the network processing functions of the main device. It is mainly used in network data proxy distribution scenarios that are replaced by dedicated data processors, such as service grid applications in the field of microservices. Service Mesh is a dedicated infrastructure layer in the microservice architecture, which usually consists of two components: a control plane and a data plane. The control plane is responsible for tasks such as service discovery, load balancing, and traffic management; the service mesh data plane (corresponding to the service scheduling engine below) is the communication plane between businesses, responsible for intercepting network traffic, and proxying and processing requests. Under the traditional service grid, the data plane is usually deployed with each service in the cluster, and sends and receives messages through the kernel protocol stack of the operating system on the main device.

[0042] When using a dedicated data processor to offload the kernel protocol stack on the main device to the dedicated data processor, the service mesh solution implemented with a dedicated data processor will also migrate the service mesh data plane to the dedicated data processor at the same time, use the dedicated data processor to receive request messages sent to each microservice on the main device, and distribute the request messages to each microservice through the service mesh data plane.

[0043] But if Figure 1 As shown in the figure, when the protocol stack + service scheduling engine is traditionally offloaded to the DPU, the request messages of different external devices or other microservices are sent to the service scheduling engine in the "network layer" of the protocol stack process in the form of NAT proxy. At the same time, the response request returned by the service scheduling engine is sent to the corresponding device in the form of NAT.

[0044] This means the network layer of the protocol stack process on the dedicated data processor must maintain NAT session tables for both directions. Maintaining the NAT session tables requires processing, consuming the dedicated data processor's computing resources. Furthermore, the more network connections the dedicated data processor establishes with external devices or other services, the more NAT sessions it must maintain. This creates a dangerous situation: a sudden surge in request messages can easily lead to insufficient memory on the dedicated data processor. In the worst case, the processor will be forced to discard request messages, impacting services. In the worst case, it can trigger unexpected interruptions and cause service downtime.

[0045] To solve the above problems, Figure 2 As shown, a first aspect of the present disclosure provides a service scheduling communication method for a dedicated data processor coupled to a master device, wherein the service scheduling communication is communication between a first service and a second service, at least one of the first service and the second service being associated with the master device, and wherein the service scheduling communication method includes:

[0046] Step S1: Receive a request message from the first service to the second service, where the request message includes a second address and a second port number of the second service;

[0047] Step S2: Keep the second address unchanged, change the second port number to a fixed port number bound to a service scheduling engine in the dedicated data processor dedicated to processing service scheduling, and record the second port number in the first data structure;

[0048] Step S3: sending the request message to the session module interfaced with the service scheduling engine, and the session module passing the request message to the fixed port of the fixed port number bound to the service scheduling engine;

[0049] Step S4: After receiving a response message from the service scheduling engine, the session module modifies the source port number of the response message based on the second port number in the first data structure.

[0050] like Figure 3 As shown, the present disclosure implements the provided service scheduling communication method for application in a computer network processing process, specifically in a protocol stack. A protocol stack, also known as a protocol stack, is a specific software implementation of a computer network protocol suite, involving the network layer, transport layer, and session layer of the OSI (Open System Interconnect) reference model.

[0051] In the embodiment of the present disclosure, the modification of the destination port of the request message is performed at the network layer of the protocol stack, that is, Figure 3 The destination port modification module is extended in the network layer. The source port modification of the response message is in the session layer of the protocol stack, that is, Figure 3 The session module in the session layer.

[0052] In the embodiments of the present disclosure, the first service and the second service in step S1 refer to two physical devices or virtual devices that establish network communication. For example, the first service is a mobile phone, and the second service is a microservice in a microservice framework, or a virtual machine or server that provides web access services. For another example, the first service is a microservice in the microservice framework, and the second service is also a microservice in the microservice framework; they represent two communicating entities using network communication. The request message is a network message sent by the first service to access the second service after the network communication between the first service and the second service is established. The second address is the destination IP address in the quintuple of the network message, and the second port is the destination port.

[0053] The service scheduling engine in step S2 is an application instance (a program) of the application layer in the computer network protocol. It should be noted that the traditional computer processes network data by processing the network message received by the network card and sent to the memory by the protocol stack process of the computer kernel, and then sends the processed network message to the corresponding application layer related program. The related program is a program running on the operating system and bound to a certain port of the operating system. The protocol stack process usually determines the application layer process to which the network message should be sent based on the five-tuple of the message. Common application layer related programs such as the Nginx proxy program, the Nginx proxy program proxies the message data processed by the protocol stack on its local machine to other nodes.

[0054] In the embodiments of the present disclosure, the present disclosure offloads the protocol stack process to a dedicated data processor, and simultaneously offloads the application layer application instance, namely the service scheduling engine, to the dedicated processor. The dedicated data processor can be a hardware device with computing and logical processing capabilities, such as a DPU or FPGA. Therefore, the service scheduling engine in the embodiments of the present disclosure is an application instance for providing data proxy distribution services to other processes on the master device.

[0055] Typically, the service scheduling engine is the data plane in the service mesh mechanism under the microservice framework, which is used to provide network data reception and distribution services to multiple microservices in the main device.

[0056] The first data structure in step S2 is a data structure created in the memory by the protocol stack process when receiving the request message for storing and describing the data packet information, specifically as follows Figure 4 As shown, the data structure consists of three parts:

[0057] Public data structure: The public data structure is the necessary information recorded when the protocol stack process processes the request message;

[0058] Private area: A private area is a space that can be used for customization by individuals or other teams.

[0059] Data area: The data area is used to store message data.

[0060] The session module in step S3 refers to a functional module corresponding to the session layer of the OSI reference model in the aforementioned protocol stack, and is a part of the protocol stack process.

[0061] The response message in step S4 refers to the response message made by the corresponding microservice or application to the request message after the service scheduling engine sends the request message to the corresponding microservice or application. The source port refers to the source port in the response message quintuple.

[0062] Specifically, in step S1, the first service receives a request message for the second service. This is done by a dedicated data processor receiving a request message sent by an external device or another process within the master device. Specifically, the request message is received by a protocol stack process offloaded to the dedicated data processor, corresponding to the network layer logic of the protocol stack process. The second service is a data access service provided by an application program residing in the master device.

[0063] In step S2, the network layer of the protocol stack modifies the destination port of the corresponding message header of the received request message to the corresponding destination port. For example, if the source port number of the message header of the request message for accessing a web service in the main device is "80", and the port number bound to the service scheduling engine is "8000", the source port number of the request message will be changed to "8000". For example, if the five-tuple of the request message is: "192.168.1.2, 566, TCP, 192.168.1.100, 80";

[0064] "192.168.1.2" represents the source IP address, which is the IP address of the first service;

[0065] "566" represents the source port, which is the port used by the first service;

[0066] "TCP" indicates that the message type is TCP message;

[0067] "192.168.1.100" indicates the destination IP address, which is the IP address of the second service;

[0068] "80" indicates the destination port, that is, the second port, which is the port used by the second service.

[0069] If the service scheduling engine is bound to port 8000, change "192.168.1.2, 566, TCP, 192.168.1.100, 80" to:

[0070] "192.168.1.2,566,TCP,192.168.1.100,8000".

[0071] The message header and the data part of the message do not need to be modified, and the port number "80" is saved as follows: Figure 4 It should be noted that, in the protocol stack process, upon receiving the request message, the first data structure of the request message is created in the memory, and all subsequent processing of the request message is performed on the first data structure.

[0072] In step S3, after completing step S2, the protocol stack process passes the first data structure corresponding to the request message with the modified destination port to the session layer, i.e., the session module. The session module then passes the message data of the request message with the modified destination port in the data area of ​​the first data structure to the service scheduling engine via memory sharing. The service scheduling engine then sends the request message to the corresponding second service.

[0073] In particular, unlike the traditional NAT implementation method, the service scheduling engine no longer binds the destination address and destination port in the NAT rule table in the NAT manner, but only needs to bind the specified port, that is, the bound address is all addresses, that is, the bound address is "0.0.0.0". "0.0.0.0" means binding all local addresses in socket communication.

[0074] In step S4, after the service scheduling engine receives the response message sent by the second service, it will send the reply message to the protocol stack process, that is, it will reach the session layer of the protocol stack process. Since the destination port of the request message has been changed in the request message of the response message, the source port of the response message sent by the service scheduling engine should be the port bound to the service scheduling engine. As mentioned above, if the destination port of the request message is "80", but it is modified to "8000", the corresponding source port of the response message is "8000". At this time, in the session module of the protocol stack process, it is necessary to replace the second port number recorded in the first data structure, that is, "80", with the source port of the response message. That is, change "8000" to "80" and then send it out.

[0075] Referring to the above example, if the five-tuple of the request message received by the protocol stack is "192.168.1.2, 566, TCP, 192.168.1.100, 80";

[0076] The five-tuple of the response message sent by the protocol stack should be "192.168.1.100, 80, TCP, 192.168.1.2, 566." This allows data plane forwarding without NAT mode. Furthermore, there is no NAT session table. Simply storing the destination port of the request message in the free area (private area) of the first data structure achieves the same technical effect as NAT mode.

[0077] In some embodiments of the present disclosure, before sending the request message to the session module connected to the service scheduling engine interface, and before the session module passes the request message to the fixed port service scheduling engine bound to the fixed port number of the service scheduling engine interface, the service scheduling communication method further includes:

[0078] Through the session module, the second port number is obtained from the first data structure and recorded in the session structure, so that after the session module receives the response data from the service scheduling engine, the second port number is obtained from the session structure and used to establish communication with the second port number of the second address, thereby generating the response message.

[0079] Some versions of the protocol stack stipulate that after the session layer of the protocol stack process sends the request message to the application layer (such as the service scheduling engine), the first data structure corresponding to the request message will be eliminated in the memory, and a session structure with the application layer will be created, namely, a session, to save the five-tuple of request data and other related information.

[0080] Therefore, in some embodiments of the present disclosure, after the modified request message reaches the session layer of the protocol stack, after the session layer passes the request message to the service scheduling engine, when the session layer creates a session with the service scheduling engine, the embodiments of the present disclosure extend an additional port field beyond the general session field to save the destination port number of the request message, that is, take out the second port number from the private area of ​​the first data structure and save it to the extended port field in the session.

[0081] Furthermore, by storing the second port number in the session extension field corresponding to the session layer of the OSI reference model, only a 16-bit memory space is required to expand the traditional session structure. Compared to the NAT approach that sets up two layers of NAT session structures and corresponding NAT rule tables at the network layer of the OSI reference model, the solution implemented in this disclosure eliminates a large amount of processing logic and significantly reduces memory requirements.

[0082] In some embodiments of the present disclosure, when the session module receives a response message from the service scheduling engine, modifying the source port number of the response message based on the second port number in the first data structure includes:

[0083] The second port number is taken out from the session structure, and the second port number is used as the source port number of the response message.

[0084] In some embodiments of the present disclosure, referring to the above example, after the protocol stack session layer receives the response message sent by the service scheduling engine, the corresponding session is determined according to the five-tuple of the response message, and the source port number of the response message is the binding port of the service scheduling engine, which should be sent to the first service. The port number of the destination port when the first service sends the request message, that is, the second port number is saved in the port field in the session, then the second port number is taken out from the session, and the second port number replaces the source port of the response message.

[0085] In some embodiments of the present disclosure, the first data structure includes a change flag field and a second port number field;

[0086] Said recording the second port number into the first data structure comprises: recording the second port number into the second port number field, and adding a change flag into the change flag field;

[0087] The method of obtaining the second port number from the first data structure and recording it in the session structure through the session module includes: obtaining the second port number from the second port number field and recording it in the session structure through the session module if the change mark field contains the change mark.

[0088] In some embodiments of the present disclosure, referring to the above example, after the destination port of the request message is modified at the network layer of the protocol stack, a modification mark is added to the corresponding first data structure of the request message, so as to facilitate the identification of the modified request message at the session layer of the protocol stack for subsequent processing. Figure 4 The private area of ​​the first data structure shown creates a corresponding change flag field and assigns a predetermined value to the change flag field.

[0089] Furthermore, at the session layer of the protocol stack, when receiving any corresponding request data, it first searches the private area of ​​the first data structure corresponding to the request message data to see whether there is a change flag field, and determines whether the value of the change flag field is a predetermined value. If it is a predetermined value, it means that the second port of the request message data has been changed, then the second port number is taken out from the private area of ​​the first data structure and saved in the corresponding session.

[0090] In some embodiments of the present disclosure, before the second address is kept unchanged and the second port number is changed to a fixed port number bound to a service scheduling engine dedicated to processing service scheduling in the dedicated data processor, the service scheduling communication method further includes:

[0091] Determine whether there is a redirection rule corresponding to the second address and the second port in the preset redirection rule table; if the redirection rule exists, change the second port number of the request message to a fixed port number bound to a service scheduling engine specifically used to process service scheduling in a dedicated data processor specified by the redirection rule.

[0092] In some embodiments of the present disclosure, as to whether to modify the destination address of the received request message, corresponding redirection rules may be formulated as needed to filter the received network messages. The redirection rules are as follows:

[0093] port-redirectrule: dst; ip_b; port_b; protocol: tcp; to_port: listen_port;

[0094] Where dst represents the destination address, ip_b represents the destination IP address, port_b represents the destination port, protocol represents the message type, and to_port represents the redirected destination port. For example, listen_port represents the binding port of the service scheduling engine.

[0095] For example, a redirection rule is as follows:

[0096] port-redirectrule "dst": "192.168.1.101"; 80; "protocol": "tcp"; "to-port": "15001";

[0097] This means that the redirection rule specifies a destination IP address of 192.168.1.101, a destination port of 80, and a TCP packet type of 15001. This means that the protocol stack on the dedicated data processor will change the destination port of any request packet received to 15001, regardless of the source address, as long as the request packet's destination address is 192.168.1.101 and the packet is a TCP packet accessing port 80.

[0098] In some disclosed embodiments, the destination IP addresses in the redirection rules are generally the IP addresses of multiple second services served by the service scheduling engine, and the destination port is generally the service port of the second service, such as port 80 commonly used by web services. If there are multiple second services in the master device, multiple redirection rules are generally set as well.

[0099] Furthermore, after the dedicated data processor receives a network message from the first service requesting access to the second service, the network layer of the protocol stack performs a rule match on the network message according to the redirection rule. Specifically, after obtaining the destination IP address and destination port number in the network message, the dedicated data processor traverses the redirection rules in the redirection rule table to determine whether there is a redirection rule whose destination port and destination IP address are the same as those of the network message. If so, it indicates that the redirection rule is matched, and the redirection destination port in the matched redirection rule is used as the destination port number of the request message, thereby completing the modification of the request message.

[0100] Furthermore, the redirection rules in the redirection rule table can be constructed in the form of key-value pairs, that is, the destination IP address, destination port, and protocol type in the redirection rule are used as the key, and the redirection rule is used as the value, forming a redirection rule table in a dictionary data structure. The destination port and destination IP address of the received network message are used as query conditions to achieve fast query. If the query is found, it is considered a hit. The redirection destination port in the hit redirection rule is used as the target port of the request message, completing the modification of the request message.

[0101] In some embodiments of the present disclosure, sending the request message to a session module interfaced with the service scheduling engine further includes:

[0102] If the redirection rule exists, before searching the routing table for the request message, the modified request message is sent to the session module interfaced with the service scheduling engine.

[0103] In some embodiments of the present disclosure, referring to the above example, Figure 5 As shown in the figure, for a received request message, if a corresponding redirection rule is found based on the request message's destination IP address and destination port, the redirection rule is hit, and the destination port is modified according to the redirection rule. Instead of searching the routing table as traditionally done to determine the request message's destination, the request message is sent directly to the session layer in the protocol stack. This prevents the modified request message from being forwarded to other routing nodes due to a mismatch between the routing table and the modified request message.

[0104] In some embodiments of the present disclosure, sending the request message to a session module interfaced with the service scheduling engine further includes:

[0105] If the redirection rule does not exist, the routing table is searched according to the second address and the second port of the request message, and the request message is sent out or sent to a service scheduling engine in a dedicated data processor dedicated to processing service scheduling according to the routing table.

[0106] In some embodiments of the present disclosure, Figure 5 As shown, if there is no hit, the traditional implementation method is used to search the routing table according to the five-tuple information of the request message. If the result of searching the routing table is to send the request message to other network nodes, the request message is sent to other network nodes. If the result of searching the routing table is to forward the request message to the internal service scheduling engine, the request message is sent to the service scheduling engine according to the traditional processing flow, that is, through the original process of the protocol stack.
