摘　　要：随着互联网络基础设施性能的不断提高,人们对主动地视频点播高清晰度、高质量的视频、音频等流媒体信息的需求也越来越多。本文提出一种改进的视频网格模型—树型模型。它以树结构来组织视频网格中的服务节点,实现了自底向上、多级、面向需求的服务体系,容易实现网格系统的层次化管理,有利于减轻中心节点负载和实现大规模视频服务的负载平衡,同时减轻网络主干负载,提高视频服务质量。Along with the continuous growth of the performance of the foundamental facilities for the internet,there are more and more requirenent of quality video and audeo information which are actively appointed.The paper proposes an improved video grid model——the tree form model.It organizes the service nodes in its video grid to realize the upward,multilevel,and required service system with the structure of tree,which easy help the grid system to realize the multilevel management and the load balance for large scale video service,and is favourable to reduce the load on central nodes and the trunks,and improve the service quality.
