摘　　要：在点对点体系结构的分布式虚拟环境系统中,由于客户机节点的计算能力和带宽的异构性,以及发生在客户机程序之间交互信息量的不同,会导致一些客户机出现负载饱和。一台客户机的负载饱和不仅影响本机程序的运行,也会对周围其他的客户机的运行产生影响,这限制了分布式虚拟环境系统的性能。研究提出了一种在点对点体系结构的分布式虚拟环境系统中避免客户机负载饱和的技术,试验结果显示了所提出的方法有效地改进了系统的性能。In distributed virtual environment systems based on Peer-to-peer architectures,because of the heterogeneity of node computing power and bandwidth,as well as the interactions among clients that can take place in can lead to the load saturation of some clients.Since client saturation not only affected itself but also had an effect on other clients,which limited the performance of distributed virtual environment systems.In this paper,an adaptive technique was proposed for avoiding the load saturation of the client computers in distributed virtual environment systems based on peer-to-peer architectures,the evaluation results show that the proposed method improves the system performance.
