Research On The Sharing Model Of Education Resources Based On Grid

Abstract:With the development of the network technology and the popularization of the informatization of education, the integration and sharing of educational information is the inevitable trend. Network resources bring about the strong service function for education, as well as the challenge to the establishment and management of education resources. However, the current situation in colleges and universities is serious: a widening gap among resources, limited sharing, non-standard and scattered data; independent application system with respective norm; non-standard and disconnected process; slow acquisition and slow updated application etc.To solve these problems, it will need a new network to complete dynamic and heterogeneous digital resources sharing. The essence of grid technology is the realization of the resources sharing. The organization and sharing educational resources based on the grid can fulfill the effective management of the network education resources on the Internet to solve these problems with distributed management.This thesis analyzes the current situation of the grid technology and grid resources sharing and emphasizes on these aspects: the description, discovery and distribution of the resources based on grid, the establishment of the system platform, the resource sharing and the security mechanism. This thesis also puts forward two innovations: the demonstration of the creation and deletion of the community model, of the message transmission mechanism in and among the communities, and of the internal structure of community; the verification of the feasibility of improvement of algorithm by improving the scheduling strategy and comparing the improved strategy with the traditional one.The application of grid technology brings unprecedented opportunity to the development of the sharing of information among universities and colleges. This thesis will play a positive role in the study of the realization of the educational resources sharing and the reuse of the resources, and will lay certain foundation for the construction of the educational resources based on grid technology, for the establishment of new learning models, for the development of intellectualized platform for the sharing of educational resources, and for the elimination of information islands.
