| 摘 要： | 在分析现有的P2P模型的基础上,结合因特网自治系统管理和网络协议层次性的特点,提出了一种基于区域自治的层次型的P2P模型.该模型依据自治系统号划分区域,区域内采用OSPF路由协议优化路由和加快收敛速度.该模型中心服务器只需记录各区域提供的共享资源名,可以大大地节省存储空间;区域索引服务器只存储本区域节点的共享资源索引信息,它能为本区域节点提供最快的服务;节点只需向区域索引服务器请求服务,可以减少网络流量.这种模型可以达到快速索引、高速共享和方便管理的目标.

| Abstract: | This paper analyzes the current P2P models,and researches the autonomous system and the hierarchical network protocol,then proposes a type of P2P model based on autonomous area and hierarchical structure.In this model,the P2P network is separated into areas by the ASN,adopts OSPF to optimize the routing table and expedites convergence within area.In this model,the central servers record the name of shared files provided by the area-servers,so as to save a lot of disk-space,the area-server records the catalo... |
