摘要
Chord是一种比较成功的P2P路由算法,但逻辑路径和物理路径之间的不一致性使得单纯依据逻辑距离进行节点路由导致很大的网络延迟,严重影响了路由效率。提出了一种基于有限范围组播的Chord路由算法,利用网络层组播技术来获得物理邻居节点,对Chord路由算法进行改进,大幅度地缩短网络路由查找延时,有效减少了路由跳数,提高了路由性能。
Chord is a successful routing algorithm,but the inconsistence between logistic routing and physical routing leads to a very big network delay if the node routing only relies on logistic distance and this will seriously affect the routing efficiency.A Chord routing algorithm based on limited network layer multicasting was proposed,which used multicast technology to obtain physical neighbor nodes and improved on original Chord routing algorithm.It can shorten network search delay greatly,reduce routing hops e...
