| 摘 要： | 文章分析了基于Gnutella协议的非结构P2P网络中利用基于分布式Caching的自适应搜索机制来进行资源搜索与使用统一索引Caching机制相比查询成功率有所降低的问题，提出了两种改进方案。通过实验与统一索引Caching机制比较，改进的搜索机制在不增加网络流量的条件下，能有效提高查询成功率。

| Abstract: | This paper analyses the problem of degrading the query success rate compared uniform index Caching mechamism when makes use of the adaptive search mechamism based on distributed caching to search resources in the unstructured peer-to-peer network based on Gnutella protocol.We propose two solutions. The experiment shows that compared with uniform index caching mechanism, our proposed mechanism can singnificantly improve the query success rate without increasing the network traffic. |
