摘　　要：在基于Winsock的网络服务中,实现可支持海量客户端请求和数据通信的服务器应用程序往往成为关键所在。针对实际应用,提出了一种基于完成端口的通信模块设计方法来解决客户端连接量巨大、小容量数据包频繁收发等并发性问题。首先介绍了完成端口的机制及相关概念,接着讨论分析了其中的关键问题并给出解决方案,然后运用IOCP模型成功构建了服务器应用系统,最后通过测试和性能分析,系统的实现效果得到了证实。In the web services based on Winsock,it is the key point to realize the application servers which could handle tremendous client requests and data communication.To meet the practical requirement,the paper proposes a method for designing the telecommunication module based on IOCP,thus solving the problems occurring in case that there are clients connections of great capacity and the frequent receiving and dispatching of low capacity data packets.The IOCP mechanism and some related concepts are presented first,then the solutions to some crucial problems are discussed,then a sever application based on IOCP is developed,and finally the validity of the system is verified by test and performance analysis.
