完成端口实现高性能服务端通信层的关键问题

为实现高性能稳定的网络通信服务,对完成端口(IOCP)应用中信息识别与提取、资源管理、消息乱序处理3个关键问题进行了分析,提出了IOCP参数扩展、内存池、对象池、环形缓冲等改进的解决方法.使用这些方法对IOCP底层进行了封装,并设计和实现了面向企业应用的可扩展网络程序通信模块.压力和性能测试结果表明,该模块能在合理资源消耗基础上支持海量并发连接,具有较高的数据吞吐量,在实际项目应用中也表现出了良好的性能.

Key issues of high-performance server communication layer by using I/O completion port

In order to achieve high-performance and stable network communication service,the key issues of client information identifying and extracting,resource management and message sequence dealing in I/O Complete Port(IOCP) development were analyzed.And the improved methods of IOCP parameter extension,memory pool,object pool and ring-buffer were proposed respectively.On the basis of underlying encapsulation for IOCP using these methods,a scalable network communication module for enterprise applications was designed and implemented.The experimental results show that the module can support massive concurrent connections,and has higher data throughput by reasonable resource consumption.The proposed solution has also showed good performance in the actual project application.
