Chord是一种结构化的P2P模型,它能快速地查找到资源的位置,但是搜索网络与实际物理地址不一致会造成查询的延迟,当节点能力差异较大时会影响网络的稳定性。混合式的P2P考虑了节点能力的差异,但是查询具有盲目性。本文提出一种基于混合结构的Chord系统,在一定程度上解决了Chord的稳定性问题、绕路问题和混合P2P结构的查询的效率问题。 Chord is a structured P2P model, which can quickly find the location of resources, but the search network and the actual physical address inconsistency will cause the query delay, when the node capacity difference will affect the stability of the network. Hybrid P2P considers the differences in node capabilities, but the query is blind. In this paper, we propose a Chord system based on hybrid structure, which solves the problem of Chord’s stability, bypass and hybrid P2P query to a certain extent.
