摘　　要：介绍了传统P2P网络的搜索模型,并分析了其存在的一些问题.针对这些问题,提出了一种基于应用层组播策略的搜索模型,它可以减少冗余搜索包,提高搜索效率,并且能够适应P2P网络拓扑的动态变化,实现良好的可扩展性和容错性.This paper introduces the traditional searching model on P2P network and analyzes its disadvantages, in terms of which a new searching model based on application-layer-multicast is developed. It can decrease redundant searching package and improve searching efficiency. Because the new searching model can adapt to the changing P2P network topology, it realizes the extending ability and fault-tolerance of the P2P network.
