基于环状层次的多簇 P2P 网络模型研究 谷科，危韧勇 (中南大学信息科学与工程学院，长沙 410075) E-mail: gk4572@ 摘 要:提出了一种基于环状层次的多簇P2P 网络模型。该方法是利用以中心节点为每个簇中心而簇内其他的节点以环 状层次扩张的拓扑结构。并且文中结合 DC-net 的匿名网络和 ECGP 层次结构模型，设计了一种动态广播路由算法。并利 用 Java 语言和网络仿真工具来模拟整个模型在实时中的运行状况。实验结果表明该环状层次的簇模型提高了资源定位 的效率，减轻了系统开销，并且拥有较好的路由性能，在非结构化的P2P 网络模型中值得推广应用。 关键词:点对点;簇;资源定位;路由算法 文章编号: 1002-8331 (2∞6)35-0136-04 文献标识码 :A 中图分类号 :TP393 Research of Clustered P2P Model of Multi-layer Loop GU Ke, WEI Ren-yong (School of Information Science and Engineering , Central South University , Changsha 410075 , China) Abstract: 币lis paper proposes an architecture of multi-layer 1ρop to build clustered P2P system.With the architecture , some peers become centers of the clusters , other peers can expand by the multi -layer loop architecture in the clusters. And the paper desi伊 s a dynamic broadcast routing algorithm by uniting DC-net anon严nous network and ECGP 缸chi- tecture model.Experiments are imitated to perfo口n by exploiting Java and net-imitated tools.Experiment results indicate that the multi甲 layer loop architecture improves resource orientation and relieves system expense.And the architecture has 伊 ite good routing function and higher perfo口nance.So it is worth popularizing and applying in unstructured P2P net? work.
