摘　　要：介绍P2P流媒体技术的发展由来,着重讨论目前P2P流媒体系统的2种典型模型:基于树状拓扑协议及扩展的模型和基于Gossip协议的模型,以及他们的最新研究进展。分析这两种模型实现新节点加入、节点离开以及节点之间数据交换的方法,总结他们在网络带宽效率、延时和可靠性之间的权衡,指出了各自的优缺点。This paper introduces the development of P2P stream medium technology, discusses two kinds of typical P2P stream medium model in current： the model of tree - based protocol and extensions and the model of Gossip- based protocol, and their new research progress, analyses the methods of both models how to add new nodes, nodes leaving,and data exchange between nodes,aggregates the different models how to balance in the efficiency of the network bandwidth,delay,and reliability,describes their advantages and disadvantages of both models.
