P2P 流量本地优化综合机制

P2P流量的飞速增长,给自治网络（如园区网、校园网）的网络边界带来很大的流量压力。为减少P2P流量对网络关键应用的影响,必须建立P2P流量的本地优化机制,使P2P流量尽可能发生在自治网络内部,缓解网络出口带宽的压力。自治网络的网络边界开始采用基于DPI的P2P流量识别技术,对识别到的P2P流量加以限制。但这种方法只是简单地限制P2P应用,将严重影响用户的流媒体点播体验。提出了一套网络边界P2P缓存机制和本地节点索引机制向结合的P2P流量本地优化策略。

P2P Traffic Comprehensive Mechanism of Local Optimization

The rapid growth of P2P traffic,to the autonomous network(such as the campus network,campus network) a great deal of traffic the network perimeter pressure.P2P traffic on the network to reduce the impact of critical applications,we must establish a local P2P traffic optimization mechanism,so that P2P traffic within the network as much as possible in self-government to ease the pressure on the network exit bandwidth.self-government began to use the network perimeter network of P2P traffic identification based on DPI technology,the identification of P2P traffic to be limited.However,this method simply restrict P2P applications,it will seriously affect the user experience for streaming media on demand.This paper presents a P2P caching network boundaries and local node index mechanism with the P2P traffic to local optimization strategy.
