摘要：

为适应海量媒体资源快速分发的要求，设计了一种基于 P2P 的媒体资源分发系统，并在CERNET2上进行了运营，本文描述了该系统的体系结构。通过引入IP地址最长前缀匹配和网络测量技术相结合的组群划分机制以克服目前P2P系统普遍存在的绕路问题。通过引入智能节点管理、CA认证、数字版权管理，解决了传统P2P分发系统中缺乏有效管理的问题。

关键词: 智能节点, CA认证, 数字版权管理

Abstract:

For fulfilling fast distribution of oceans of media resources, this paper puts forward a content distribution system based P2P, which has operated on CERNET2. We describe the system architecture. By introducing the method of cluster partition which combines IP address longest prefix matching with network measure technology, the system overcomes the detouring problem existing popularly in current P2P systems. By using intelligence node management,CA certification and digital right management, it has resolved the inefficient management problem of traditional P2P distribution system.

Key words: intelligence node, CA certification, digital right management
