| 摘 要： | 对于地理上分布较广的流媒体服务系统，采用分布式流媒体代理服务器集群，可减少上联广域带宽消耗，缩短访问距离，增强服务能力，关键要解决代理服务器的协作问题．用户请求调度的判定问题实际上属于NP完全问题，提出分布存储的流媒体代理服务器协作算法，并对近似解和最优解之间的相对偏差进行了讨论．

| Abstract: | As for streaming media system, which geographic distribution is wide, adopting the distributed streaming media proxy server cluster can reduce consumption of WAN bandwidth of upward joint, shorten interview distance and enhance ability of service and the key is to settle collaboration. The judge of customer request is the NP complete problems. The article puts forward the streaming media proxy server of distributed storage coordination algorithm and discusses the relative deflection between approximate result and best result. |
