IOCP机制在交通信号控制系统通信服务器中的应用

摘要

针对交通信号控制系统客户端连接量巨大、数据通信频繁等特点,提出了一种基于IOCP机制设计高性能的通讯服务器.首先介绍了信号系统总体结构及IOCP模型工作原理,描述了基于IOCP模型的通信服务器设计与实现过程,讨论分析了实现中需考虑的关键问题并给出解决方案,最后通过仿真测试,验证了该法的可行性.%In response to the features that there great amount of clients connection and data frequent communication of traffic signal control system,A design method based on IOCP mechanism to realize the server is proposed in this paper. The IOCP and system structure are presented first,then the server' s design and implementation process are described,and the solutions to some crucial problems are discussed,finally the validity of the method is verified by simulation test.
