摘　　要：结合网格的发展需求,在现有网格资源发现研究的基础上,设计了基于P2P的分层分布式网格资源发现模型,并对Chord资源发现算法提出了改进方法.该模型可实现基于属性的动态分布式查找,扩展性好,并在一定程度上提高了资源搜索效率.Combined with the new demands, and based on the study of grid resource discovery, the hierarchical and distributed grid resource discovery model were designed based on P2P, and the improved search algorithm was proposed based on the Chord algorithm. With excellent expansibility, the model supports dynamic and distributed attribute-based resource query, and can improve the efficiency of resource query to some extent.
