摘　　要：服务器通道调度技术是解决大规模流媒体点播应用系统资源瓶颈问题的有效途径。它的基本思想是通过让用户尽可能共享同一个数据流来提高系统资源的利用率。本文综述了媒体点播系统中通道调度方案的研究现状,分析了一些典型方案的设计思想和方法,指出目前通过调度方案研究中的不足,并对今后该领域需要进一步研究的问题进行展望。Scheduling technology of server channel is an effective approach for addressing the bottleneck problem of resources in large scale streaming media application systems. To reach higher level of system resource utilization,it lets users to share a single stream as much as possible. This paper summarizes the state-of-the-art in the research on channel scheduling schemes in media-on-demand system. We also analyze the design idea of several classical schemes. Additionally,some disadvantages of study on channel scheduling algorithms are discussed. At last,the key issues to be further studied in this area are pointed out.
