摘　　要：给出一种Gnutella半结构化自适应拓扑方案——ISATS。基于"搭便车现象"的网络特征,进行拓扑结构的改进。基于查询算法中的分级邻居缓存机制,提出自适应拓扑方案。模拟实验数据分析表明,该方案减少了网络通信量和查询响应时间,提高了查询效率及成功率。This paper proposes an Improved Semi-structured Adaptive Topology Scheme（ISATS）. Based on its features of notable free-rider phenomenon, it proposes an improvement to its topologic structure. By imposing the ranked neighbor caching scheme which is used for Gnutella querying, it proposes a new adaptive topology scheme. Simulation data analysis shows this scheme makes significant reduction in the network load and the response time. It enhances the efficiency of enquiries and the success rate of enquiries.
