网格环境中资源共享模型的研究

The Study of Resource-Sharing Mode in Grid Environment

资源共享,尤其是高性能资源的共享是网格环境中需要解决的一个关键问题。在网格环境中,资源通过服务的方式提供,而GT3InformationService和P2P技术正是实现服务管理和共享的重要手段。文章首先介绍了InformationService和P2P技术的工作原理,然后,结合这两种技术的特点,提出了一种使用P2P网络进行容错的树形资源共享结构的网格环境中的服务实现共享的模型,并进行了分析。

Resource sharing, especially for the high-performance resources, is a key p1roblem to be solved in Grid environment. Resources are exposed as services in the grid, and GT3 Information Services and P2P are the primary techniques to implement the management and sharing of services. In the first place, the paper gives a glimpse of the working principle of Information Services and P2P. Then, a new resource-sharing model, in which a P2P network is used for fault-tolerant, is proposed based on the combination of Information Services and P2P. Analysis of the new model is described in the end.
