| Grid technology is an important development direction of current computer technology. It integrates resources that are connected by means of communication measures into an organic whole, and supplies user with a new kind of computing platform based on Internet. Resources in Grid environment distribute widely, change dynamically, and work on isomerous platform under control of different management policy, which presents uncommon demands to the information service, and makes the research on Grid information service a significative and challenging task.This dissertation primarily researches into Grid Information Service. The writer bases her research work on the most popular Grid middleware Globus Toolkit, and takes Grid Platform of Fault-handling of Electric Power as the application background, and her work includes: (1) researching into grounded theories of Grid and key technologies of Grid information service, and analyzing thoroughly the bottom implementation mechanism and related function interfaces of MDS in GT3.2; (2) analyzing the shortage of traditional Fault-handling System of Electric Power, and putting forward the necessity of importing Grid technology into this application domain; (3) doing a thorough application analysis for the Grid Platform of Fault-handling of Electric Power, and bringing up the architecture based on Globus Toolkit for this application domain, and then locating focus on the information service, finally designing and implementing the service information management module; (4) successfully installing, configuring and testing GT3.2 under the Linux operation system, and establishing a simple virtual organization as a simulative Grid environment; (5) designing testing instances fit for the simulative Grid environment, and developing Grid services for testing related functions; (6) summarizing the writer's research work, looking forward to the developing directions, and settling the base of succeeding work. |
