对等系统作为一种可扩展的手段, 在大量自治节点之间共享数据。由于共享数据是 非结构化的,它们不遵循全局模式,基于XML的描述 可以用来提供一种统一的方式来查询异构的 数据在我们的研究中,我们感兴趣的是设计一个完全分散的方法,特别是在节点之间的路由路径查询的问题, 一个对等系统我们的方法是基于(a)选择和维护 专门的数据结构,称为过滤器,有效地总结了内容, 也就是说,以及(B)使用这些过滤器来构建 将具有相似内容的节点分组在一起的覆盖网络。
Peer-to-peer systems are gaining increasing popularity as a scalable means to share data among a large number of autonomous nodes. Since the shared data are unstructured and they do not follow a global schema, XML-based descriptions of the data can be used to provide a uniform way to query the heterogeneous data. In our research, we are interested in designing a fully decentralized approach for the problem of espciently routing path queries among the nodes of a peer-to-peer system. Our approach is based on (a) selecting and maintaining specialized data structures, called filters that efficiently summarize the content, i.e., the documents, of one or more node and (b) using these filters to build an overlay network that groups together nodes with similar content.
