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。This paper proposes an architecture of muhi-layer Loop 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 designs a dynamic broadcast routing algorithm by uniting DC-net anonymous network and ECGP architecture model.Experiments are imitated to perform by exploiting Java and net-lmitated tools.Experiment results indicate that the muhi-layer loop architecture improves resource orientation and relieves system expense.And the architecture has quite good routing function and higher performance,So it is worth popularizing and applying in unstructured P2P network.
