【摘要】 网格计算(Grid—computing)和P2P计算(Peer-to-Peer Computing)是近年来分布式计算发展中出现的两种计算技术。两者都是将大规模的分布的资源有效地组织起来,供用户方便、快捷、透明的访问和共事。尽管存在着很大区别.但是两者存在着交汇和融合的趋势。网格,将结合P2P的特性,逐渐将形成一种融合的大规模、资源多样异质、动态、自组织的资源共享环境。在这种未来的网格环境中,有效地进行资源定位是一个基础性的同题,而传统的资源定位方案都不能很好地满足需要。针对上述环境,探索了一种基于P2P方式的双层逻辑架构的资源定位方案,并给出了初步的算法步骤。更多还原

【Abstract】 Grid and Peer-to-Peer computing are two distributed resource sharing environments developing rapidly in recent yean. The final objective of Grid, as well as that of P2P technology, is to pool large sets of resources effectively to be used in a more convenient, fast and transparent way. We can speculate that, though many difference exists, Grid and P2P environments will converge into a large scale resource sharing environment that combines the characteristics of the two environments: large diversity , high heterogeneity (of resources), dynamism, and lack of central control. Resource discovery in this future Grid environment is a basic however, important problem. In this article, We propose a two-layer and p2p-based architecture for resource discovery and design a detailed algorithm for resource request propagation in the computing environment discussed above.更多还原
