网格信息服务系统是网格系统中的重要组成部分.由于网格技术和Web服务融合为开放的网格服务架构(OGSA),原有的网格信息服务系统需要重新构建.本文从分析传统的网格信息服务系统MDS,R—GMA和Hawkeye入手,研究了最新开放的网格体系结构的规范,构建了一种具有森林结构的基于OGSA的网格信息服务系统模型OGIS,描述了主要模块的功能和实现方法,探讨了基于OGSA的网格信息服务系统关键技术和解决手段.该网格信息服务系统为基于OGSA的网格信息服务系统的开发提供了一种有效的方案.
The grid information service system is a very important part of grid computing. An old grid information service system needs to be reconstructed as a result of the combination of grid and web service. This paper discussed quondam grid information service systems such as MDS, R-GMA and Hawkeye and substantially analyzed the specification of open grid services architecture (OGSA). An OGIS (grid information system based on OGSA) with forest structure was constructed, the functions and means of realization of OGIS modules were presented, and the key technologies and solutions to OGIS were described. OGIS provides an effective blue print for developing a grid information service system.
