摘要
分布式散列表(DHT)是现有结构化P2P系统普遍采用的一种方法,它能将资源的唯一标识映射到资源位置,Tapestry就是一个基于DHT的基础平台。资源共享是P2P技术应用较广的一个领域。本文以一类典型的带有元数据的资源MP3音乐文件为例,介绍了在Tapestry基础上实现一个基于元数据的P2P资源共享系统MPIS的详细过程,它能够根据资源的多个属性来定位所需资源。
The method of DHT is widely adopted in existing structured P2P system,in which any resource can be located by its unique identification, and Tapestry is an overlay based DHT. P2P technology is widely used in the resources-sharing field. Using a kind of file containing metadata in the file format, MP3, as an example, the implementation of a metadata-based P2P resources-sharing system on the basis of Tapestry is introduced in detail in this article, the required resources can be located using several properties of the resource in MPIS.
