摘要 针对结构化P2P架构中DHT算法面临的路由性能问题和节点加入/退出时的结构维护问题,提出了一种基于推荐策略的搜索算法RPSA,对现有DHT算法加以改进,并在P-Grid算法的原型系统上验证了RPSA的有效性。 In DHT algorithm of structured P2P architecture, to increase the routing performance and decrease the maintenance cost when peers join/leave the network, a recommendatory policy-based search algorithm(RPSA) was put forward. RPSA improved the existed DHT algorithm,and the performance of it was validated on the P-Grid prototype system.
