一种多层Chord的资源定位算法

A resource location algorithm based on multiple level chord

文中提出了一种基于底层拓扑信息构建P2P覆盖网络的多层Chord算法——Multiple Level Chord(ML-Chord),结合将资源进行分类存储的方法,完成了P2P网络对资源搜索定位能力的增强。仿真结果表明,在P2P网络完成指定资源的搜索定位时,ML-Chord算法显著减少了节点在覆盖层上的逻辑跳数以及节点之间的通信时延。

A resource location algorithm based on multiple level chord is proposed in this paper,in view of the underlying topology of the overlay network and together with resource classification,in order to improve the performance of P2 P network,specially decreasing the number of logical jumps in the overlay network and the communication delay between the nodes.
