针对结构化P2P网络资源搜索技术中Chord算法进行深入研究和分析，分别从路由信息冗余、节点延迟划分、查询路径判断等3个方面对传统Chord系统进行讨论和改进，提出了相应的改进方案，并通过仿真实验对方案进行性能测试和验证分析，证明改进方案减少了资源查询路径长度，降低了信息的转发次数，减轻了网络的负担，从而能更好提高资源搜索效率。
Abstract:
In this paper，the search technology-Chord algorithm is researched and analyzed deeply based on structured P2P Web. And the traditional Chord system has been debated and improved，respectively from three aspects of the routing information redundancy，the node delay and judgment of query path. The corresponding improvement scheme was put forward，and some performance tests and confirmatory analyses by simulation experiment were conducted. And the results show the improvement scheme reduces the resource query path length and the number of forwarding of information，alleviates the burden of the network， thus it improves resource search efficiency.
