摘　　要：Chord系统中没有考虑到逻辑网络拓扑和物理网络拓扑不相匹配而导致的路由效率低下,由此提出了一种利用节点IP地址信息使节点得以聚类从而达到系统逻辑网络拓扑与物理网络拓扑在一定程度上的匹配,对Chord系统改进得到了TChord系统模型,通过仿真实验证明了TChord系统在路由延迟和覆盖网络路由跳数方面比Chord系统有明显的改进,从而效提高路由效率.Chord does not take into account the mismatching problem between logical network topology and physical network topology, which would cause inefficient routing. In this paper, a scheme based on IP address information of node is proposed, which can be reached matching between logical network topology and physical network topology in a certain degree. TChord system is based on improvement of Chord. The result of experiments verifies the TChord system, compared with Chord system, has obvious improvement on the delay of route and the hops of overlay networks.
