P2P协议识别方法研究

Research of Identifying P2P Protocols

鉴于目前国内互联网现状,基于各种P2P协议的网络流量飞速增长并占据了大部分的网络带宽。因此,在很多情况下,对P2P流量的检测是十分必要的。文章结合P2P网络中出现的问题,分析了P2P对网络流量的影响,提出了P2P流量识别的几项关键技术并对其优缺点做出评价。

Whereas the current actualities of domestic Internet,the internet traffic based on all walks of P2P protocols increases rapidly,so that it takes a lot of resources of the internet bandwidth.As a result of that,the detecting of the P2P traffic seems very essential on most occasions.This article,according to the problems appear in the P2P networks,analyzes the influences which the P2P networks put on the internet,then it concludes several important methods of the identifying P2P traffic,and finally it assesses the advantages and disadvantages of these methods.
