Abstract:
Resource discovery is a key problem in grid environments. Most of existing resource discovery mechanisms still can not effectively provide categorizing mechanism of resources. On the basis of P2P grid, a kind of resource discovery mechanism based on Distributed Resource Tree(DRT) of multi-attribute queries is proposed. This distributed resource tree organizes and classifies resources by Primary Attributes(PA). It can make the load of nodes on P2P grid be balanced dynamically.

摘要: 资源发现是网格环境中的关键问题,目前许多的资源发现机制并不能有效地提供资源的分类。为此,在P2P网格基础上提出一种基于多属性查询的分布式资源树的资源发现机制。该分布式资源树通过资源的主属性进行资源的组织和分类,能动态灵活地实现P2P网格中各节点的负载动态平衡。
