| 摘要 |
流媒体业务正变得日益流行 ,然而传统流媒体系统存在着种种不足。最近兴起的 P2P技术能够利用客户端节点的资源减轻服务器和骨干网的负担 ,为解决流媒体内容分发提供了一个新的方向。本文首先阐述了传统流媒体
系统的不足之处 ,以及 P2P流媒体系统与之相比的优势 ,而后通过对 P2P 流媒体技术研究现状的详细调查 ,分析了P2P流媒体技术的两个分支 — — — 直播与点播的特性要求 ,并以 P2P流媒体系统的典型代表为例说明了当前所采用的主流技术。最后 ,本文就 P2P流媒体技术在应用层拓扑的建立激励机制、 安全性、 无线应用以及网络编码等方面的研究进行了讨论 ,指出了进一步的研究方向。

Media st reaming is becoming more and more popular , however , there exist s some limitations in traditional streaming systems. P2P technology can efficiently uses the resource of client peers to alleviate the load on servers and backbone network , providing a new direction for streaming system. This paper describes the disadvantages of traditional streaming systems and advantages of P2P streaming systems. Based on the survey of recent P2P streaming systems ,an analysis of the characteristic of live media and VoD media is given. Moreover , some representative P2P streaming systems are taken for example to illust rate the mainst ream technology. This paper concludes with open research issues on P2P streaming technology : const ruction of application layer topology , incentive mechanism , security , wireless application , network coding and etc.
Keywords Peer2to2Peer , Media st reaming , Application layer multicast |
