| 摘 要： | 提出了Barnet,一个基于特征信息定位的Peer-to-Peer网络模型.该模型的目标是为广域网络构建一个高性能、高可用、协同、负载均衡的海量信息资源服务平台.分别描述了Barnet原型系统的构建目标、系统结构、信息资源的组织及信息资源的定位策略.描述了Barnet中所采用的一个基于Peer-to-Peer的分布式命名、定位、查找算法NetShot,讨论了NetShot中节点的命名、节点加入离开、节点间邻接关系和节点间消息传递方式等基本问题.提出了基于特征信息定位技术的概念,并讨论了在Barnet中使用基于特征信息定位技术对具体信息资源进行查找、定位的具体策略.

| Abstract: | Barnet, an infrastructure for attribute addressable P2P network, is brought forward in this paper. This infrastructure aims to provide high availability, collaborative, large-scale wide area information service. The architecture, information organization and access model of Barnet are described in this paper. NetShot is a peer-to-peer based Naming, Locating and Lookup algorithm. As proof that NetShot is useful in developing decentralized applications. After discussing the naming, joining, departing and neighboring model of NetShot, this paper proposes the concept of attribute addressable P2P network, and describes the details of lookup and location strategy which is adopted in Barnet. |
