Communication method based on user-mode protocol stack, and corresponding apparatus

A communication method based on a user-mode protocol stack and applied to a client, wherein the client comprises an application layer, the user-mode protocol stack, and a hardware layer, wherein a target application of the application layer corresponds to at least one W thread, each of the at least one W thread is a thread for processing data of the target application, wherein the user-mode protocol stack comprises a plurality of N threads, a routing module, and transmission control protocol hash tables that are in a one-to-one correspondence with the plurality of N threads, wherein each of the plurality of N threads is a user-mode protocol stack thread, wherein the hardware layer comprises a plurality of non-uniform memory access (NUMA) nodes, and wherein the plurality of N threads are in a one-to-one correspondence with the plurality of NUMA nodes, and the method comprises:

• obtaining a target correspondence by using the routing module, wherein the target correspondence comprises a correspondence between a connection file descriptor (FD) and a target N thread, the target N thread is an N thread selected by the routing module for a first W thread that initiates a connection operation, the first W thread is one of the at least one W thread, and the target N thread is one of the plurality of N threads;
• and
• communicating with a service side by using the routing module based on the target correspondence.

A computing device, comprising one or more processors and a non-transitory computer-readable storage medium storing a computer program

• to be executed by the one or more processors, wherein the computer program comprises instructions that when executed, cause the one or more processors to perform operations based on a user-mode protocol stack and applied to a service side, wherein the service side comprises an application layer, the user-mode protocol stack, and a hardware layer, wherein a target application of the application layer corresponds to at least one W thread, each of the at least one W thread is a thread for processing data of the target application, wherein the user-mode protocol stack comprises a plurality of N threads, a routing module, and transmission control protocol hash tables that are in a one-to-one correspondence with the plurality of N threads, wherein each of the plurality of N threads is a user-mode protocol stack thread, wherein the hardware layer comprises a plurality of non-uniform memory access (NUMA) nodes and a network adapter, and wherein the plurality of N threads are in a one-to-one correspondence with the plurality of NUMA nodes, and the operations comprise:
• obtaining a first correspondence by using the routing module, wherein the first correspondence comprises a correspondence between a listen file descriptor (FD) of a first W thread and a plurality of shadow FDs, the plurality of shadow FDs are generated in a one-to-one manner for the plurality of N threads, and the first W thread is one of the at least one W thread;
• obtaining a second correspondence by using the routing module, wherein the second correspondence comprises a correspondence between a target N thread and a connection FD, and the target N thread is an N thread selected by the network adapter from the plurality of N threads when a communication connection to a client is established;
• and
• communicating with the client by using the routing module based on the first correspondence and the second correspondence.
