摘　　要：针对Gnutella网络的可扩展性不好及资源搜索效率低等问题,提出一个I-Flooding资源搜索策略。I-Flooding策略是以删除冗余链接、二阶段路由转发策略和以共享文件数为指标构建簇为特征。实验表明,I-Flooding资源搜索策略可以有效地减少网络中冗余消息数量,搜索查询返回结果也明显增多。According to the problem of scalability and low efficiency of resource search,presents a new scheme,I-Flooding.I-Flooding has many characteristics such as deleting the redundant links,two-phase descriptor forwarding method and building clusters based on the number of sharing files of Servent on the network.Experiments show that I-Flooding scheme is better than Flooding scheme on the Gnutella network,since the number of redundant messages is reduced greatly,and the number of search results is increased.
