一种对等网络分层管理资源定位模型

摘要

According to the feature of Small World situation in network and the principle of data stream locality,this paper designs a peer-to-peer network resource locating model of layer-management based on Kademlia.lt makes the most use of reconfiguration of Kademlia's topological structure and priority visiting of neighbouring physical nodes to increase efficiency of visiting nodes and optimize routing location.Simulation tests indicate that the designed model inherits the merits of Kademlia,and it is superior to original Kademlia model in routing location and average logic path length.%通过研究网络中小世界现象特征与数据流局部性特点,基于Kademlia协议设计了一种对等网络分层管理资源定位模型.模型通过重构Kademlia协议的网络拓扑结构,利用物理邻近节点访问优先的方法,来提高节点访问效率并优化节点的路由选择.仿真结果表明,设计的模型在继承了Kademlia模型优点的基础上,在节点路由选择和节点查找的平均逻辑路径长度等方面的性能均优于Kademlia模型.
