摘　　要：针对P2P网络的最基本特征:网络节点对等,每个节点既是服务器又是客户端。本文提出了一个简单高效的解决P2P流量识别方法,该方法没有用到应用层的协议,不需对数据包进行应用层解析,只判断源地址、目标地址及端口号。实验结果表明该方法执行效率高,并且对加密数据包以及未知P2P应用的数据包都有很好的识别效果。this paper aims at the basic peer to peer character of P2P network： each peer is both server and client, the paper proposed a simple and high efficient method to identification of P2P traffic. This method is based on source address, destination address, source port and destination port, but never need the application level protocol and packet characters. This method shows high efficiency in the test experiment. More importantly, it is useful to identify the encrypt packet and unknown P2P Application.
