摘　　要：Gnutella网络是一种非结构化对等网络模型。与结构化对等网络模型相比,它更能够适应对等网络波动性较大的特性。但Gnutella网络在进行资源搜索时,存在着过度消耗网络资源、大量查询消息被毫无意义的进行转发等问题。本文提出了一种通过改进Gnutella网络的组织机制,进而改进Gnutella网络搜索机制的方法。Gnutella network is an unstructured modal of P2P network.compared to structured P2P network modals. It adapts to the high fluctuation of P2P network better. It is robust and highly flexible. But it dumps too much traffic into the Internet and causes a significant amount of meaningless forwarding of query messages when searching resources. This paper proposes a new resource searching policy to improve the efficiency and reliability of resource searching,based on the improvement of the organization mechanism in Gnutella P2P network.

关 键 词：GNUTELLA协议 P2P网络的搜索机制 用K叉树构造子网络
