摘　　要：P2P技术凭借其开放性、可扩展性和高性价比等优点成为了目前解决在线视频问题的有效手段之一。虽然P2P技术在文件共享和IP语音等方面的应用已经基本趋于成熟,但其在在线视频领域的应用尚处于起步阶段,还面临着许多需要解决的问题。对P2P在线视频进行了全面而深入的分析,首先介绍了网络广播分类及体系结构设计,整理和总结了已有的关于P2P在线视频系统的测量研究结果,最后对于P2P在线视频信任和污染攻击等安全问题进行了概述。P2P technology has become one of the most effective approaches to internet video broadcast for its simple deployment, good sealability and high cost-effectiveness ratio. P2P applications such as file download and voice over IP have gained tremendous popularity, while video broadcast is still in its early stage and there are a number of key technical challenges that need to be overcome. This paper provided a comprehensive and in-depth analysis of the P2P video streaming, and discussed the characteristics of video broadcast applications and reviewed the approaches to video streaming systems architecture design. After surveying the results of measurement studied on P2P video streaming systems, then the paper overviewed security aspects of P2P live video streaming systems such as pollution attack and DoS attack.
