The Research Of Implementation And Architecture Of Mediator System On Grid

As the various needs of people for information increase rapidly, grid computing developspromptly, which has been considered as the next tidal wave of IT development. By providing auniform framework for exchange information and middleware, grid computing implements theintegration and sharing of information, resource and application.Based on the research of OGSA architecture and globus toolkit architecture model, the paperanalyzes the frame model of server and client of grid services in GT4 environments, analyzes thedeploy process of Grid services, makes normalize design for installation steps of GT4. Above allanalyzes carefully the Data Management-OGSA-DAI of GT4. The OGSA-DAI is prototypeservice of grid data service. By analyzing the implementation mechanism carefully, we discussthe way to extending the function of OGSA-DAI.Under Red Hat9 operating system, we install the GT4 and OGSA-DAI, and with theMediator System, we design and research the way to access Mediator System under DAI. UnderWindows operating system, we develop and deploy a Grid Service instance successfully.
