P2P大规模流媒体调度技术研究

Research on Scheduling Technologies of Large-Scale Media Streaming over Peer-to-Peer Networks

随着宽带、IPV6、3G等技术的日渐成熟,流媒体应用已成为Internet承载的重要业务.调度技术是保证大规模可信流媒体服务质量的关键问题之一.对典型流媒体调度和分发技术进行综述,归纳分析了基于P2P网络环境下树型、网状以及混合拓扑结构的流媒体技术的优缺点,对mesh网下的资源发布于查找、服务节点选择、数据块调度等进行了重点分析和评述.依据流媒体应用的发展趋势,预测了P2P大规模可信流媒体调度技术在适应复杂网络,及结合云技术等方面的研究方向与内容.

With the rapid growth of media streaming services,scheduling technologies of large-scale media streaming have been the core of streaming research.The course of media streaming service systems was firstly outlined.Studies the scheduling polices based on tree,mesh and Hybrid topology.And mainly analyzed the resources issuing and searching mechanism,peer scheduling and block scheduling algorithms in mesh-based topology.Finally the expected directions based on recent research in this area were also proposed.
