摘要
本文针对对等网由于逻辑网络和物理网络的拓扑结构不匹配导致物理路由效率低下的问题,在结构化P2P网络Chord的基础上,提出一种层次式Chord模型。模拟实验表明,该模型能够有效提高物理路由的效率,并保持良好的逻辑路由效率和较低的维护代价。
This paper analyzed the unmatched topology problem between the overlay network and the physical network, which result in inefficient routing. Based on the structured P2P network Chord, this paper proposed a layered Chord model. Simulation experiment shows that layered Chord can greatly improve routing efficiency so as to reduce physical path length of lookup and keep close overlay path length of lookup and network maintenance against Chord.
