IntroductionWith the rapid development of network resource sharing, instant messaging, video transmission and other services, P2P networks have been widely used. The P2P network of distributed technology [1] has become a focus of international academic direction [2]. P2P network in accordance with the structure of the network can be divided into structured P2P network and unstructured P2P network, compared to unstructured P2P networks, structured P2P network no flooding resource search algorithm, which has a strong system scalability research value is also higher, including the chord network model is a structured P2P network in the most classic network model. This paper analysis the traditional chord model and some modifications chord model, then put forward a new improved chord model, though the theory and simulation analysis, prove the new chord model having a good efficiency.
