基于P2P流媒体的教学体系结构研究

随着网络通信和多媒体技术的发展,人们对网上音、视频的多媒体教学内容需求日益增长,基于流媒体技术的远程学习是未来人们受教育的新方法。然而流媒体的质量并不能令人满意,传统的网络教学系统大多采用C/S模式,服务器以单播的形式传输媒体流。结合当前流行的对等网络（P2P）技术和流媒体技术,介绍了如何构建基于P2P流媒体技术的远程网络教学系统的问题。结合P2P网络的优点,对系统中流媒体传输进行了改进,从而降低流媒体服务对骨干网的负载,避免网络阻塞。

Teaching Architecture Based on P2P Streaming Media Technology

With the development of network communications and multimedia technologies,the demand for the multimedia-teaching content,including video/audio information,grows quickly.The remote learning based on streaming media technology is a new approach to education.In combination of the popular P2P technology and the streaming media technology,this paper describes how to build up a remote network teaching system based on P2P streaming media technology.With the advantages of P2P networks,streaming media transmission system is modified,thus reducing the load of streaming media services on the backbone network and avoiding the network congestion.
