摘要 在下一代宽带教育网信息高速公路建成之后,如何更好地为我国高等院校、科研院所的师生提供宽带主流应用以及相关的资源服务,是目前迫切需要解决的问题,而如何更好地实现大规模视频课件资源的共享和分发服务和相关应用则是其中的一个关键问题。已有的CDN和P2P技术是目前资源分发的主要技术,二者各有优势和不足。在这个背景下,本文提出新型的基于CDN-P2P混合模式的视频课件资源大规模分发技术架构,重点设计了总体架构,阐述了主要实现机制,包括用户引导机制、CDN内容分发机制、课件在终端的P2P分发机制等。基于新型架构,本文设计了CDN-P2P混合分发实现方案,分析了资源分发流程,最后总结了全文,展望了CDN-P2P混合模式的视频课件资源分发技术的发展前景。
