分布式资源共享的网格信息服务

网格技术使得广泛的大规模的资源共享成为可能。在如此分布、多样、动态的网格环境中，信息服务成为任何网格软件框架的重要部分，它为发现和监控提供了最根本的机制，也因此为系统规划应用行为奠定了基础。介绍的信息服务系统结构，明确了底层查询和注册协议以及优化方法，从而简了化单个实体纳入（包括支持不同查询语言和发现策略的集合索引）信息结构的过程。

Grid information services for distributed resource sharing

Grid technologies enable large-scale sharing of resources. In these distributed, dynamic, diversiform settings, Information services are a vital part of any Grid software infrastructure, providing fundamental mechanisms for discovery and monitoring, and thus for planning and adapting application behavior. Our architecture defines low-level enquiry and registration protocols that make it easy to incorporate individual entities into information structures, including aggregate directories supporting different query languages and discovery strategies. These protocols can also be combined with other Grid protocols to construct additional higher-level services and capabilities such as brokering, monitoring, fault detection and troubleshooting.
