摘要
视频点播数据传输的离散程度,给P2P流媒体点播技术带来了极大的挑战。分析了P2P流媒体点播技术的基本问题,从媒体资源定位和分发两个方面介绍各种已提出的协议和算法,结合P2P视频点播的特点和网络应用的实际需求分析其优点和不足,并以此为基础提出有待解决的主要问题,为进一步的研究和应用提供有益的参考。
The diversity of video-on-demand data transmission imposes great challenges for the development of Peer-to- Peer (P2P) Video-on-demand (VoD) streaming. Presented primary problems of developing P2P VoD streaming system. Then introduced existing protocols and algorithms of P2P VoD streaming with respect to locating supplying peers and content distribution, and summarized their merits and demerits according to the requirements in practical networks. Some open issues were finally presented for further studies and deployment of P2P VoD streaming.
