摘　　要：针对资源发现在网格规模及应用不断扩展过程中变得越来越复杂的问题,在网格环境中融合Web Service技术,同时引入P2P思想,将资源发现模型分为内外两层,提出一个分层网格资源发现模型,简称SRDG(Stratified Resource Discovery of Grid),并在制造网格中基于元数据对网格资源分类,设计出SRDG-M体系结构。实验证明,该模型有效解决了集中式模式带来的节点瓶颈等问题,并大幅降低分布式系统中资源发现产生的网络流量,具有高效性、可扩展性和鲁棒性。To find numerous and complicated Grid resources effectively is a very important factor affecting the Grid＇ s performance. Along with the expansion of Grid＇ s scale and application, ways of resource discovery become increasingly complicated. This paper combined Web Service technology with Grid environment and introduced the concept of P2P equivalence. And a new stratified model is proposed, which has two layers-the inside one and the outside one. When applying this architecture in Manufacturing Grid, it is named for SRDG-M. Simulations show that through this innovation the problem of chock point in traditional model is readily solved. Also, SRDG-Mmodel greatly reduces the network traffic in distributed system, and is effiective, scalable and robust.
