摘要
分布式视频点播网络成为当前的研究热点,文章从目前比较流行的CDN技术(内容分发网络)的缺点着手,提出以“鼎点天源”宽带平台为架构的分布式视频点播网络。在分析基于媒体服务器的统计策略和统计调度策略的的基础上,深入研究了视频服务器组间负载均衡策略,同一视频服务器组不同媒体服务器间的负载均衡策略。实际运营系统测试表明该调度策略有效地解决了分布式视频点播网络的负载均衡问题。
This paper presents a distributed video-on-demand network architecture,which gain an advantage over CDN technology(Content Delivery Network).On basis of analyse the theory of statistics dispatch policy for pump server,the problem that how to balance the pump server load between Video-on-demand Units and between different pump servers in a Video-on-demand Unit is clarified.Through experiment,it verifies statistics dispatch policy can solve the problem of load balance in distributed vod network effectively.
