A Method of Realizing Network Service Proxy Based on IOCP Mechanism

Abstract

A method for realizing a network service proxy based on the IOCP mechanism disclosed by the present invention comprises the following steps: accessing the request of the client through the IOCP; the proxy server filtering and processing the accessed client request; Filtered client requests are distributed to the server with the lowest load for processing. The method of the present invention not only increases the number of accesses of terminal users, but also increases the number of accesses of servers, and can be expanded at any time according to needs.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for realizing network service agent based on the IOCP mechanism. Background technique [0002] In the information age, network communication is very important, and it is an important technical means to connect various devices together. As the communication scale becomes larger and larger, the design of the network center node becomes very important, because it is the bottleneck point that affects the communication efficiency. [0003] To deal with multi-client connections, you can use synchronous communication + multi-threading to deal with it, but the problem with this method is that when each client connects, a thread must be opened at the central node, because all these threads are running, the system has to context switch between all runnable threads, and thread switching is quite a waste of time. [0004] The IOCP model, also known as the completion port model...

Problems solved by technology

[0003] To deal with multi-client connections, you can use synchronous communication + multi-threading to deal with it, but the problem with this method is that when each client connects, a thread must be opened at the central node, because all these threads are running, the system has to context switch between all runnable threads, and thread switching is quite a waste of time

Improving the performance of the application and improving the performance of the hardware cannot really solve this problem, because the performance of a single server is always limited, and the network requests are bursty. When some important events occur, the network access will rise sharply. , resulting in network congestion, using cluster technology to achieve load balancing in the application system can better solve this problem

[0007] For now, most applications use the mechanism of IOCP to connect a large number of concurrent requests to the system, but there are still some defects. For example, the method provided by the IOCP-based mass terminal device access system of the patent No. A large number of concurrent requests are accessed, but how to distribute these requests reasonably does not involve

This does not meet the actual needs very well
