【摘要】 在P2P网络中,如何定位节点对非常重要,不同拓扑的P2P网络采用不同的路由策略.介绍了一种基于P2P网络的分级路由策略.该策略结合了非结构化Flooding路由策略和结构化的Pastry路由策略,将整个网络分为两级,并引入了虚节点的概念,使整个网络趋于一个稳定的结构.实验证明该路由策略融合了两者的优点,不失为一种有效的路由策略.更多还原

【Abstract】 In P2P networks,how to position nodes is very important.Different topological P2P networks use different routing strategies.In this paper,a classification routing strategy based on P2P networks is introduced.The strategy combines the unstructured Flooding routing strategy and the structured Pastry routing strategy,and divides the network into two tiers.It introduces the concept of virtual nodes,which makes the whole network have a stable structure.Experiment results reveales that the routing strategy can combine their strengths,and it has stronger application and scalability.更多还原
