摘　　要：为在3TNet上开展视频业务提供高质量媒体内容的分发支持,实现高性价比的可运营内容分发服务,采用CDN与P2P结合的架构,实现了基于P2P的可运营媒体内容分发网络。系统采用了灵活的内容分发算法管理平台,方便根据需要采用各种合适的副本分发、内容缓存算法。系统具有节点、媒体内容和系统部署成本高度可控,运营质量高,运营成本低等特点。In order to support the high-quality VoD service on 3TNet, we designed a media delivery system based on P2P and Interact. To ensure the business operation, We adopt the P2P concept in CDN infrastructure, which connects all the cache servers in P2P way. We designed and realized a content distribution algorithm management platform, which enables us to adopt various replica distribution and content caching algorithms, to ensure the QoS of the service. The design has great advantages on the management of system, media content and the cost to deploy the system, which ensures the business operation.
