The Research Of Grid Service Based On OGSA

The Grid technology is an up-to-date technology in the area of wide-area network computing, especially in the area of wide-area high-performance computing. It enables the coordinated use of geographically distributed resources in the absence of central control and strong trust relationships. The Grid technology is thought to be the next wave of development of information technology. However, the management of resources in the grid environment is complex as they are heterogeneous and geographically distributed. This dissertation proposes an effective resource management using the agent method among distributed resources. In this dissertation, we discuss a Mobile-agent-based Grid Resource Management Model (MGRMM). In this model, resources will be deployed like commodity exchange and the technology of agent will be applied in the resource management to resolve a series of problem in the grid environments. OGSA (Open Grid Services Architecture) is called the next generation grid architecture. It evolves from the early five levels hourglass model. Building on concepts and technologies from the Grid and Web Service communities. A basic premise of OGSA is that everything is represented by a service. Computational resources, storage resources, networks, programs, databases, and so forth are all services. In this dissertation, we research the architecture of the OGSA, Build the grid entironment of GT3.we also programme a grid service named Resourcecompare in the grid entironment.
