Digital Library Information Resource Organization And Scheduler Pattern Research In Grid Environment

Grid is the third wave after traditional internet and the web. The essential of the grid is to achieve the connectivity of all of the global resources.The grid is a set of newly technique that be constructed on the Internet, it merges high-speed internet, high performance calculator, large database, sensors, the long range equipments into a whole, and provide more resource, functions and alternations to technological personnel and ordinary user.There are three principles to measure whether a system can be called grid or not, 1) coordinates resources that are not subject to centralized control; 2) using standard, open, general-purpose protocols and interfaces; 3) to deliver nontrivial qualities of service. A system which strictly meet the above three principles can be called grid.rid architecture includes the Fabric Layer--local resources interfaces; Connectivity Layer--manage communications; Resource Layer--sharing a single resource; Pool Layer-- correspond resources; Application Layer—self-definition grid application. It defined the basic construction of grid, the function and purpose of the architecture, and how to alternate these components do.In the domestic and international grid research and applied realm, digital libraries have played a pivotal role. It is the principal part in organize use manage grid information resource, and the foundation establishment to composing the higher-level application of grid.With the constant advance of grid, digital library in grid environment will not only be a single resource system or a information retrieval and serve system based on digital resource, but also a user-centered dynamic mechanism to assemble information resources, information services and information using activities. Its ultimate...
