Paper Abstract

It is publicly considered that the next generational Internet technology is grid computing, which supports the sharing and coordinated use of diverse resources in dynamic virtual organizations from geographically and organizationally distributed components. Grid computing characters strong computing ability and broad width information exchange. After analyzing the characteristic of grid computing, this paper expatiates on current application status of grid computing with middleware technology on DVGE-G and the problems it faces. Cooperating with IBM, Microsoft and HP, Globus Toolkit as a standard for grid computing is widely used to develop application on grid, which can run on Unix and Windows operation systems. On the basis of "the five-tiers sandglass structure" and web services technology, Globus presented Open Grid Services Architecture (OGSA), which centered on grid services. According to the characteristic of DVGE-G and the development of current grid computing, this paper put forward the Grid-Oriented Distributed Network Model for DVGE-G. Virtual group is corresponding with the Virtual Organization in OGSA service, which is easier and more directly for the dynamic virtual groups in GDNM to utilize the grid source and communication each other. The GDNM is not only more advantage to the distributed database consistency management, but also it is more convenient to the virtual group users acquiring the DVGE-G data information, The architecture of DVGE-G designed in this paper is based on OGSA and web services, which is keep to "the five-tiers sandglass structure" of the OGSA. This architecture is more convenient to utilizing grid service and decreasing the conflict with the grid environment. At last, this paper presents the implementation of DVGE-G and the interfaces of Grid Service.
