【摘要】 针对一种新型的基于社区多角色的结构化P2P网络模型特点,提出了一种新的查询算法,即迭代扩展查询算法。该算法利用反馈机制,将已经返回的结果统计信息反馈到前端查询Q,指导查询Q向外路由的策略。将该算法与Chord网络查询算法进行了分析比较,使用P2Psim进行模拟验证。仿真结果表明,该网络模型性能稳定,资源查询速度快,通信量小,结果优良。更多还原

【Abstract】 In this paper,a new query algorithm is proposed for a new structured P2P network model based on community and multi-role,that is,the iterative extended query algorithm.The algorithm uses the feedback mechanism,statistical information of the results has been returned back to the front query Q,to guide outward route strategy for Q.This paper compares and analyzes the query algorithm with Chord network,finally,simulates and verifies them using P2Psim.Simulation results indicate that good stable performance of the network model,resource query quickly,less traffic volume and the better results.更多还原
