该文提出一种基于簇环状层次的P2P网络模型,该方法是以中心节点为簇中心,而簇内其它节点以环状层次扩张的拓扑结构,从而使得整个簇内形成一种紧密的逻辑结构。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,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。实验结果表明该簇环状层次模型提高了资源定位的效率和容错性,使得整个网络节点管理更为合理,且有较好的路由性能,在非结构化的P2P网络模型中值得推广应用。
This paper proposes a P2P network model based on the cluster ring level. This method is based on the central node as the cluster center, and other nodes in the cluster to expand the ring topology, so that the entire cluster to form a tight logic structure. In this paper, DC-net anonymous network and ECGP hierarchical model, a dynamic broadcast routing algorithm is designed, the use of JAVA language and network simulation tools to simulate the entire model in real-time operating conditions. The experimental results show that the cluster ring hierarchical model improves the efficiency and fault tolerance of resource location, makes the whole network node management more reasonable and has better routing performance, which is worthy of popularization and application in the unstructured P2P network model.
