【摘要】 针对多媒体服务的特点，提出了一种双层服务器集群系统MMWS，分析了所包含的Web请求服务子集群MMWS_O和多媒体请求服务子集群MMWS_M的“中心－本地”结构，并讨论了系统的工作流程。最后分析了MMWS的两大特点：高可扩展性和服务就近性。更多还原

【Abstract】 This paper presents a highly scalable framework of server clustering named MMWS, which consists of a Web request server sub-clustering MMWS_O and a multimedia request server sub-clustering MMWS_M . It firstly describes the "Center-local" architecture of MMWS and then discusses the scheduling schema. The performance of MMWS is also analyzed at the end of the article.更多还原
