摘　　要：分析了网络及Web应用的发展对Web集群请求调度提出的新要求,在此基础上提出了一种基于文档组织分布的新请求调度模式。针对该请求调度模式的特点,提出了一种分布调度、分布路由的Web集群体系结构,该结构结合了多分配器集群和分布式集群的优点,能保证系统的可扩展性,并能有效减少集群内的通信开销和消除单点故障。In this paper we analyse the new demands for request scheduling of web server cluster brought by the development of network and web application, and propose a new request scheduling mode based on document organisation and distribution. Aiming at the traits of such request scheduling mode, a new cluster system architecture, Distributed Scheduling and Distributed Routing, is proposed. This architecture merges the merits of multi-dispatcher cluster and distributing cluster, it can guarantee system scalability, and can effectively reduce the communication cost within the cluster and eliminate single point fault.
