摘要
针对流媒体的点播和直播服务,提出了基于P2P的流媒体应用层多播和点播的解决方案,构建了基于超级节点和普通节点的两层体系结构的视频流媒体模型,描述了模型的总体结构,分析了资源传输机制。基于校园网对模型进行了测试,测试结果表明,模型能够实现基于流媒体应用的多点数据快速互传。
For realizing the basic service of streaming media,video on demand and live video,we present a proposal of application layer multicast,video on demand,build a video frequency streaming media model with two kinds of peers,SP and peer based on P2P,describe the structure of model,analyze resources transmissions.Finally,some test records of this model are expressed with the table,that show a solution of ALM（application layer multicast） and video on demand with P2P model.
