Abstract: Low expandability and overweight of telecom backbone in mainstream P2P network model have been hampering the development of P2P system. Though structured overlay network model solves part of problems, it is difficult to be applied into Internet due to its limitations. By analyzing other P2P models, this paper provided a hybrid model based P2P network model, and described some important processes in the model. A manager protocol and new key matching algorithm were also proposed to enhance the management and practicability of P2P network.
