适应于分布式虚拟地理环境服务的对等网络模型研究

P2P Network Model Conformed to the Service of Distributed Virtual Geographic Environment

  • 摘要: 阐述了分布式虚拟地理环境系统体系结构的研究现状,对当前分布式虚拟地理环境系统建设所面临的技术难点和挑战进行了深入探讨,在此基础上将对等网络技术引入到分布式虚拟地理环境系统的建设中。对现有的对等网络路由结构的适应性进行了深入的比较和分析,进而设计了一个适应于分布式虚拟地理环境服务的大规模对等网络模型,并对该模型进行了模拟测试和分析,达到了预期的效果。

     

    Abstract: 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.
