摘　　要：资源搜索是P2P网络的关键问题。介绍了Gnutella网络资源搜索路由机制,分析了Gnutella网络的现有改进算法及其存在的问题,针对这些问题,提出了一种基于询问—应答策略的网络资源搜索路由机制的改进策略,在不影响搜索效率的情况下,能减少大量的冗余信息和有效地提高可扩展性,并且还具有自适应性。Resource searching is the key problem in P2P network. The resource searching mechanism in Gnutella network is introduced. By analyzing the present improved algorithm of Gnutella network as well as its disadvantages, a new network resource searching routing mechanism based on query-response policy is proposed. Then its scalability is effectively improved, its redundancy in the transmission of information is reduced and self-adaptability is obtained when not affecting searching efficiency.
