Abstract:

Grid computing provides a robust paradigm to aggregate disparate resources in a secure and controlled environment. Grid architectures require an underpinning Quality of Service (QoS) support in order to manage complex computationand data-intensive applications. However, QoS guarantees in the Grid context have not been given the importance they merit. In order to enhance the functionality offered by computational Grids, we overlay the Grid framework with an advanced QoS architecture, called G-QoSM. The G-QoSM framework provides a new service-oriented QoS management model that leverages from the Open Grid Servic Architecture (OGSA) and has a number of interesting features: 1) Grid service discovery based on QoS attributes, 2) policy-based admission control for advance reservation support, and 3) Grid service execution with QoS constraints. This paper discusses the different components of the G-QoSM framework and presents an initial prototype implementation.
