I/O复用代理在网络隔离系统中的应用研究

Application Research on I/O Multiplexing Proxy of Network Isolation System

应用代理为网络隔离系统中的其他业务提供了运行平台。首先通过比较传统代理技术,提出了适用于网络隔离环境的代理模型,然后分析比较了I/O复用技术,提出了在网络隔离系统中使用epoll实现应用代理的方法,并阐述了详细的实现过程。最后对系统性能进行了研究,提出了应用数据的缓存方法和基于TTL的数据重发机制。

Application proxy has provided a running platform for other applications in the network isolation system. Firstly, it proposed a suitable proxy model for the network isolation system through comparing traditional proxy solutions. Secondly, it analyzed I/O multiplexing in practical use and proposed a method to realize application proxy in the network isolation system based on the epoll technology. Then, it described the realization process in detail Finally, it researched the system perform- ance, and proposed data caching method and re-sending mechanism based on the TTL of IP protocol .
