基于PeerCast的P2P流媒体多点播放缓存管理设计

DESIGN OF BUFFER MANAGEMENT SCHEME FOR MULTICAST P2P STREAMING MEDIA BASED ON PEERCAST

随着网络流媒体的广泛应用,P2P流媒体技术作为C/S结构的有力补充越来越引起人们的重视。而现有P2P单点播放系统并没有充分发挥出P2P网络的优势。在研究开源P2P流媒体软件PeerCast的基础上,提出了P2P流媒体多点播放的设计方案,针对如何在多源环境下进行准确有效的缓冲区管理给出了算法实现,并实验证明其稳定性和高效性。

While the transmission of network streaming media is widely used, P2P streaming media technology is drawing increasing attention as a strong substitute to traditional C/S structure. However,existing P2P unicast system is not able to maximize the system effectiveness. In this paper it proposes a design scheme of P2P streaming media multicast system, based on the research of open source P2P streaming media software Peercast, the algorithm implementation aiming at accurate and effect buffer management in muhi-source system is made. According to the result of the experiment, the scheme approves to be stable and efficient.
