基于DSM-CC U-N的VOD系统资源会话管理器设计

摘要

The session and resource manager is a ISA compliant management system for managing the sessions and resources to maximize the utilization of limited network bandwidth. For the purpose of managing the sessions and resources, DSM-CC User-toNetwork protocol is implemented in the design that adopt IPQAM resources dynamical management and static mapping scheme to guarantee that real-time stream is correctly delivered from video server to the requesting terminal.%资源会话管理器以ISA架构为平台,负责对交互服务中资源和会话进行管理,实现有线带宽资源的最大利用率.为了便于管理资源和会话,该设计遵守DSM-CC U-N协议规则,采用静态映射机制保证视频服务器正确定位交互终端STB,对IPQAM的带宽进行动态分配.
