TCP long connection communication system and method

Abstract

The invention provides a TCP long connection communication system and method. The system comprises a TCP communication module, a message and data management module, an information data storage module, a distributed memory cache module and a load shunt module, wherein the TCP communication module is used for receiving data requests sent by terminal equipment, calling corresponding service logical processing interfaces in a service logical processing module according to request information, receiving operation results returned by the message and data management module and sending TCP communication data and instructions or control grammars to the terminal equipment; the message and data management module is used for calling the service logical processing interfaces to conduct management and operation on messages and data; the information data storage module is used for managing equipment information and communication system service data; the distributed memory cache module is an open source distributed memory cache system; the load shunt module is used for dynamically distributing current requests to a server with the current minimum load when receiving new TCP connection requests. The abstract, event-driven and asynchronous TCP long connection communication system and method are based on transport protocols can achieve high concurrency, high real-time performance and dynamic expansion.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to an abstract, event-driven, asynchronous TCP persistent connection communication system and method located on various transmission protocols (such as TCP / IP and UDP / IP). Background technique [0002] In the system application of network communication based on TCP / IP, before the real read and write operations, a connection must be established between the server (Server) and the client (Client). When the read and write operations are completed, the two parties no longer need to They can release the connection when the connection is established. The establishment of the connection requires three handshakes, and the release requires four handshakes. In each TCP network communication process, the establishment and release of each connection requires resource consumption and time consumption. ,Such as figure 1 , 2 Shown: [0003] 1. Three-way handshake to establ...

AI Technical Summary

Problems solved by technology

[0017] To sum up, the simple TCP short-connection communication mode can no longer meet the requirements. It has become a technical solution to find a technical solution based on TCP long-connection communication mode that supports high concurrency, high real-time performance, and dynamic scalability.
