The Peer-to-Peer Network Based on Topic-Relative

The architecture of P2P network is one of the most important factors that affect the expansibility,the security,the efficiency of resource-locations,and the network-using rate of the P2P network.According to whether there is a central server or not,the architecture of P2P network can be classified into the centralized network and the non-centralized network,either of which has its advantages as well as disadvantages.In order to overcome the disadvantages of the architecture of the existing P2P network,the authors brought forward a topic-relative architecture of P2P network,discussed the correlative technical issues about the network architecture of P2P network,then analyzed the algorithms of building and finding the network's resources and finally gave some examples to illustrate this network.
