Research And Application Of Grid-based Teaching Resources Shared

With the development of the Grid technique and the conception proposing with the Grid service, Grid services have infiltrated all sectors of society. The Grid integrates the entire Internet into a huge super computer and implements the comprehensive sharing between various resources such as: computing resources, storage resources, data resources, information resources, knowledge resources and the expert resources. The advantage of the grid is not only the strong ability of processing the data, but also the low computing cost because of the use of the free resources on the Internet, it implements the sharing of resources and aliments the isolated resource island eventually.The paper first introduces the definition, architecture of the Grid, do some research on the technique implementation of the grid services. OGSA (Open Grid Services Architecture) provides an open standard and a technique solution, while OGSI (Open Grid Service Infrastructure) provides the implementation model and the technique criterion of OGSA. CT3, which is a free open source software with fully compatible with OGSA and OGSI standard, is provided by project Globus for the development of various grid applications. It has become the kernel development platform of several large grid projects.The paper also analyzed the problems emerged in current education software such as: the problem of separation in sharing and managing educational data resource, the problem of integration resources. Proposed a grid service based solution named"Research of Teaching Resource share Base on Grid"to eliminate resource island.We developed a Grid service which can work well in the system which indicates the sharing teaching resource technique based on Grid service can achieve some excellent effect.At the end of the paper, some insufficiencies of my work are summarized, and some future research points are listed too.
