A grid information service system ODIS based on OGSA

摘要: 網格信息服務系統是網格系統中的重要組成部分.由于網格技術和Web服務融合為開放的網格服務架構(OGSA),原有的網格信息服務系統需要重新構建.本文從分析傳統的網格信息服務系統MDS,R-GMA和Hawkeye入手,研究了最新開放的網格體系結構的規范,構建了一種具有森林結構的基于OGSA的網格信息服務系統模型OGIS,描述了主要模塊的功能和實現方法,探討了基于OGSA的網格信息服務系統關鍵技術和解決手段.該網格信息服務系統為基于OGSA的網格信息服務系統的開發提供了一種有效的方案.Abstract: 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.
