Abstract :
The emerging Open Grid Service Architecture (OGSA) promises to enable virtual management of resources in an effective way by means of grid services in dynamic autonomous grid environment. To support automatic resources utilization in this paradigm, grid services that meet requester´s functional requirements must be able to be found and selected from a number of service providers based on their QoS requirements. In order to enable quality-driven grid service selection, we present an extensible QoS model to evaluate the quality of grid services. Based on this QoS model, a new matching algorithm is proposed that can help service requesters to select appropriate service provider in terms of QoS requirements preference, which shows its effectiveness applied for grid service discovery in grid.
