摘要
在分析CDN架构和简单P2P模式分析的基础上,提出CDN-P2P混合模式的流媒体点播平台方案。重点描述在PRTP辅助下CDN-P2P混合模型的设计方案,主要包括混合模式的流媒体点播平台总体架构设计、上层CDN架构和终端P2P的结合点(骨干节点)的设计实现、PRTP协议支持的混合式分发实现。通过实验证明CDN-P2P混合模式增强了P2P流媒体点播平台的健壮性和扩展性。最后展望该领域的主要研究方向。
On the basis of analyzing the CDN （content delivery networks） architecture and the simple P2P mode, this paper introduces a kind of streaming media VOD platform solution which combines CDN and P2P characters. It focuses on introducing the design schemes of CDN-P2P hybrid architecture supported by PRTP, mainly the design of overall architecture.of the mixed mode streaming media VOD platform, the design and realization of the connection node （ strong node） of the top layer CDN architecture and the P2P client,and the realization of the mixed distribution solution which supported by the PRTP protocol. The contrast experiment proves that this kind of CDN-P2P mixed mode improves the robustness and scalability of P2P streaming media VOD platform. In the end of this paper, it gives a view of the main research perspective of this field.
