摘要: 有效地发现网格的各种资源是影响网格整体性能的一个重要因素。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,提出一个非集中式的网格资源发现方法,并应用于制造网格之中。实验证明,该模式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。

Abstract: 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 combines Web service technology with grid environment and introduces the concept of P2P equivalence.And a new stratified model is put forward,which has two layer—the inside one and the outside one.This architecture in manufacturing grid is applied.Simulations show that through this innovation the problem of chock point in traditional model is readily solved,and so on.Also,it reduces the network traffic in distributed system greatly.This new model is provided to be valid,scalable and robust.
