Application Research Of Grid Service Base On OGSA

With the popularization of Internet, the different people's demands of message to Internet also sharply adding up, and the swift development of Grid Computing is being accompanied with Internet. Unite Web Service's technique up to date, and take shape new generation grid architectural structure OGSA. Serve was all is a fundamental idea of OGSA, among the OGSA, everything wholly is serving. Considering the concrete distinguishing feature of grid environment, the OGSA proposed "Grid Service" from the base of former Web Service.At first the thesis was completed the research of the grid definition and the realization technique of the grid service in the grid computing, summarized the relationship and difference between Grid Service and Web Service. Probed the realization of the grid computing platform-Globus Toolkits 3.0.Next analyzed Grid Service, and contrasted the different architectural structures on grid, and elaborated the application value of OGSA. Detailed analyzed Web Service's technique and Globus Toolkit which correlate with OGSA, and utilized them to clarify Grid Service application on the OGSA.Choose OGSA and its realization means Globus Toolkit to do worthwhile to achieve the technique, and proposed the settlement scheme the grid service creating. Moreover unite information acquisition application backdrop, and achieved an information acquisition example on Grid Service. The information acquisition platform certificated the problem of the service call from different platform.Last summarized the deficiency of our work, and pointed out the perspective of Grid Computing.
