摘要 针对当前P2P(peer-to-peer)网络只能通过固定的协议和服务有限地利用节点资源的弱点提出了主动P2P网络(APN)架构。文中结合P2P网络技术和主动网络技术各自的优点,把P2P网络的服务和协议代码封装在数据包中,随数据包一起传送,并由需要的节点加载和执行,从而完成服务和协议的动态扩充和部署。文中基于此架构提出的视频点播系统的设计方案,提高了服务质量。 Nodes in a current peer- to- peer (P2P) system can provide only limited services through fixed P2P protocols. In such a P2P system, services and protocols cannot be deployed on demand,and the resource of the nodes cannot be fully exploited because the ways to utilize them are limited. To get over this wcakness,a new active P2P network architecture (APNA) was proposed,which mixed"active network"and"peer- to- peer network". In APNA,services and network protocol codes are encapsulated and transmitted as data packets, and they will be loaded and executed in the active nodes if needed. The automatic source code understanding and query system was developed and deployed on APN. Based on this architecture a VOD system design was proposed in this paper. And the QoS is enhanced.
