Faced to the challenges and difficulties of constructing distributed virtual geographic environment(DVGE),the approach for building DVGE based on Peer-to-Peer(P2P) network is put forward,which are resulted from the analyzing of the current structure of DVGE and the adaptability of the existed P2P network.For the method,the key problem is that how to design the logical model and topology structure for P2P network conformed to the service of DVGE.Therefore,the four-tier P2P logical model for DVGE system are presented,and for supporting the functions of this P2P logical model,the topology structure of the P2P routing model named spatial related hierarchical circinal routing model is designed.The test DVGE system,which has simulated its communication performance between the peers in the network,is also presented,and the prospective performance is gotten.
