R&D Of The Grid Service Oriented Middleware For The Integration Of Designing Software

The paper advanced the OGSA- Based Enterprise Application Integration Architecture when having made a thorough study on integrating middleware technologies, with a first great attempt made to introduce the grid technology into EAI, and then carried out the R&D of GSOM middleware for the designing software integration, combining with 863 national project.Chapter 1 introduced some basic concept related to this paper, then analyzed the current research situation of EAI and its shortage and middleware technologies' developing trend, and then, according to these, the objective of the thesis was pointed out and the research frame presented.On the basis of the solid study of the Distributed Computing Technology and the Open Grid Service Architecture, Chapter 2 advanced the OGSA- Based Enterprise Application IntegrationArchitecture unprecedentedly, presented tow new definitions--GSOM and Service Router, thendetraversed its tier structures and worked its running mechanism over.Research on the designing software's integration was made in chapter 3, and according to its specialty compared to MIS's integration a GSOM middleware's design blueprint came into being which allow remote multi users access designing software cooperatively. Also, its prototype, main functionality modules and its running mechanism were analyzed detailedly in the chapter.Chapter 4 mainly discussed the realization of GSOM's key technologies including running designing software, communicating with it and its termination. At last, the author implemented some parts of GSOM's grid services, and presented their config in OGSI.net grid service container.According to security questions and security requirement that the integration architecture faced, Chapter 5 brought forward new security model and policy; and according to GSOM middleware's special security requirement, the chapter provided role-based access control model that can meet GSOM's security requirement well.In chapter 6, all achievements of the thesis are summarized and the future research work is sketched out.
