摘　　要：本文研究了现有的各种P2P模型的资源搜索方法包括基于中心目录服务器的对等网络资源搜索、基于洪泛搜索机制的非结构化对等网络以及基于分布式哈希表的结构化对等网络,重点研究了基于分布式哈希表的结构化对等网络,并分析了各自的优缺点。最后得出基于分布式哈希表的结构化对等网络依据资源标识符进行查找,可扩展性和查找效率都很高。This paper studies resource seach method of present P2P model including based on center index server model and based on flooding search unstructural model and based on distribute hash tables （DHTs） structural model. The study put emphasis on structural P2P model which based on DHTs. At last, we give advantage and disadvantage respectively. structural P2P which based on DHTs search resource by resource id, expansibility and search efficiency is the best.
