摘　　要：近年来兴起的P2P流媒体应用造成了网络带宽的巨大消耗,精确识别P2P流量具有很强的实际意义。通过抓取PPLive的流量数据进行协议分析,主要关注系统获取节点列表方式、资源交换方式和数据传输方式等实现方法,进而总结协议特征,提出了一种基于协议分析的PPLive流量识别方法。In recent years the rise of P2P streaming media application has resulted in the enormous consumption of network bandwidth, accurate identification of P2P tragic has a strong practical significance. This paper analyses the protocol through grabbing PPLive traffic, with focus on how the system acquires nodes list, how resource is exchanged, how data is transmitted, etc. Moreover, it proposes a PPLive traffic identification method based on protocol analysis by summing up the characters of protocol.
