摘 要: | 在基于P2P的视频点播系统中,节点邻居选择策略对服务质量有很大的影响。提出一种基于DHT(Distributed Hash Table)的P2P覆盖网络下视频点播(Video-on—demand)的解决方案。通过网络坐标系统的拓扑发现能力,充分结合DHT网络高速搜索和VoD视频点播的特性、构造一种具有高效邻居选择能力、高用户自由度、高可靠性、扩展性的体系架构。针对架构设计中资源发布份发、资源的搜索、视频点播的实现等关键问题提出了解决方案,分析了系统的特性。

Abstract: | The neighbor-selection strategy in P2P VoD system is an important factor for its QoS.In this paper,a VoD(Video-on-demand) scheme based on DHT(Distributed Hash Table) under P2P overlay network is proposed.Via exploiting the topology discovery ability of distributed network coordinate system and integrating the fast-searching property of DHT with the trait of VoD system,a user-free framework with high robustness and scalability has been designed.Aims at the key issues of the user-free framework,has given the solutions for users to publish and demand video resources. |
