摘　　要：首先分析了对等网络电视的系统组成和工作原理,然后通过抓取的网络流量从获取节点列表、资源交换和数据传输等方面进行协议分析,进而通过对这些实现方法的特点进行比较和总结,结论对今后类似系统的分析和开发有着指导作用。Firstly, the P2P system and the working principle are analyzed, and the protocol is analyzed through the method of grabbing network traffic. The analysis focuses on how nodes acquire information of others, how nodes connect with each other, how data is exchanged, etc. And then, these characteristics are compared and summarized through the methods of implementation. The conclusion is instructive when developing a P2P network TV system.
