摘要: 研究内容分发网络(CDN)与对等网络(P2P)的混合模型,提出一种CDN与P2P、树形结构与网状结构双重混合的流媒体直播系统架构。设计基于CDN-P2P的树网结合直播系统模型,阐述核心树的主要构建机制,介绍网状结构的节点选择算法。系统仿真结果表明,与纯P2P模型及CDN-P2P混合模型相比,该系统的播放和启动延迟较小。

Abstract: Based on Content Delivery Network(CDN) and Peer-to-Peer network(P2P), this paper designs a new double hybrid architecture of live video streaming system. based on research of hybrid CDN-P2P network, which are hybrid CDN-P2P, and hybrid Tree-Mesh. Mainly Elaborate the system architecture, construct of CoreTree and peer selection algorithm. And through the system simulation, result shows that this system has low delay of playing and starting than other popular architectures.
