P2P视频直播软件节点行为分析

摘要

为区分不同的视频直播软件在节点行为上的差异，本文提出基于网络层和传输层的节点行为分析方法，该方法利用节点的通信状态分布、传输的数据包大小及分布、传输协议和端口号等内容来分析节点交互行为。通过对PPLive、PPStream和QQLive三款视频直播软件的实验表明，该方法能够较好的体现视频直播软件在节点行为上的差异。%In this paper, we present a method based on network layer and transport layer for peer behavior a- nalysis. The method adopts the peersp communication status distribution, size and distribution of packets, transport layer protocol and port number to analyze the peer communication behavior. The experiments on PPLive, PPStream and QQLive proved that the method can clearly reflect the difference of peer behavior of different live streaming softwares.
