网格环境中资源发现与监视机制的研究

Research on Resource Discovery and Monitoring Mechanisms in Grids

在分布、异构的网格环境下,资源发现和监视机制是关系到资源共享和协同工作效率的关键。为了提高资源共享和协同工作效率,文中基于Globus中资源发现和监视服务机制,提出了一种基于移动代理的网格资源发现和监视模型,并介绍了该模型中资源发现和监视的过程,指出该模型具有高可靠性、良好的可移植性和扩展性、安全性高以及可以显著提高工作效率等优点,更适合与动态变化的网格环境。

The resource discovery and monitoring mechanism is a key problem in grid. It has great impact on the efficency of the resource sharing and collaborating in such environments. In order to improve the efficency of the resource sharing and collaborating, the paper discusses the rescurce discovery and monitoring in Globus, and suggests a resource discovery and monitoring model based on mobile gent, and analyzes resource discovery and monitoring strategies, Towards the environments, the resource discovery and monitoring model based on mobile agent is better.
