摘要 研究移动多媒体用户数量的增加引起的网络瓶颈与多媒体代理服务器负载大的问题。提出1种基于逻辑簇的客户请求调度策略CCRSS(Cluster-Based Client Request Scheduler Strategy)。首先根据移动设备的物理位置按照客户定位算法确定请求者所在的逻辑簇。然后簇节点选择者根据节点服务能力利用节点选择策略,筛选能够响应客户请求的簇节点。最后簇节点判断者判断请求者能否作为簇节点从而服务未来的客户请求,确定请求者位于哪个逻辑簇中,并更新簇信息管理者。最后定理证明该系统能够有效的降低多媒体的抖动率和减少服务器带宽负载。 Considering the bandwidth-constrained and the burden of proxy server problem for MM（Mobile Multimedia） systems affected by client persistent increasing,A Cluster-based Client Request Scheduler System CCRSS is raised.Firstly,located the requester in the logic cluster is.Secondly,the cluster super-node selection strategy is used to elect appropriate cluster-nodes to provide resource for service-requestors.Then these nodes are orgawized and managed to form clusters.This system can reduce burden of proxy server and transmission bandwidth effectively,which is proved by math way.
