基于异步I/O模型的双机TCP代理的研究与实现

The Research and Implementation of Double Entities TCP Proxy Base on Asynchronous I/O Model

一些特殊领域的应用对于性能要求很高,而通用单机TCP代理不能满足需求。文章分析了TCP代理的实现机制,借鉴TCP连接管理有限状态机、以异步I/O模型研究和实现了双机TCP代理,并将其应用于一个安全网关项目,取得良好效果。

General single entitie TCP proxy can't satisfy the requirements for high performance in some special applications.By analyzing the implementation mechanism of TCP proxy , we research and implement two entities TCP proxy structure model base on asynchronous I/O model by referring to Finite State Machine of TCP connection management.It has been applied to a secure gateway project successfully.
