摘要 文章在分析了目前流行的一些视频点播负载均衡技术的优缺点上,提出结合有效的副本策略、流言协议和超节点等相关技术,构建了一个视频网格系统的副本策略模型,并分析了此模型的整个视频点播过程和节目副本在节点间的传播情况。最后,对中心骨干网络和相关节点进行了一系列的实验模拟,证实了模型系统的可行性及其带来的好处。 This paper analyzes VOD's load-balance technique, proposes the integration related techniques such as replication policy, rumor protocol, superpoint. And areplicationpolicy constructed, the process of VOD and replicated program transmission between the feasibility and benefit of the proposed model. model of Grid-VOD system is thus nodes. The experiments prove the
