摘要: 针对当前实时流媒体系统的维护开销较大和节点缓存资源块发布不完整等问题,提出了一种基于Chord的结构化的流媒体直播系统RR-Media.该系统中的节点分为超级节点和普通节点,所有路由信息都在超级节点上完成;任何节点都可以发布资源,节点之间通过定期交互来声明自己的存在.仿真结果表明RR-Media具有较低的网络延迟、非常小的维护开销和高效的节点缓存资源发布完整性.Abstract: Aiming at present the real-time streaming media system's problems caused by high maintenance overhead and the cache resource block of node released of integrity,a structuring live streaming model RR-Media based on Chord was proposed.Nodes were divided into super nodes and ordinary nodes in this system,all the routing information is being done on the super node.Any node can publish resources,and declare their own existence through regular interactions.Simulations result showed that RR-Media drastically has lower network latency and little maintenance overhead and efficient integrity of node resource publishing.
