摘要: 本文针对结构化P2P网络overlay层面路由计算导致网络层面路由性能较低的问题,提出一种基于重定向机制的路由优化算法。它通过重定向机制使节点逐渐收集同一子网内的节点信息,并将同一子网内的节点作为邻居,从而显著降低平均查询路径长度,而不加重网络负担。本方案能够极大的提高结构化P2P网络路由性能,从另一个角度解决overlay层面与网络层面的不匹配问题。

Abstract: This paper describes a routing optimizing method on structured P2P network. By utilizing redirect mechanism, it gradually gathers the nodes’ information at the same sub-network, and takes these node as its neighbors, thus it dramatically reduces the average searching path length, and does not introduce more traffic into the network. It greatly improves the routing performance of structured P2P network, and successfully solves the mismatching problem in a different way.
