Asynchronous Policy-Based Grid Resource Management Mechanism for QoS-Constrained Applications Asynchronous Policy-Based Grid Resource Management Mechanism for QoS-Constrained Applications

Grid computing [1][2][3] enables the virtualization of distributed computing and data resources such as processes, network bandwidth and storage capacity to create a single system image, granting users and applications seamless access to vast IT capabilities. It brings together all heterogeneous resources and allocates them efficiently to applications. As Grid grows, the complexity of resource management in Grid dramatically increases. To manage the Grid resources efficiently, Policy based resource management system is suitable to the complex management environments. The condition of the grid resources with time space has an uncertainty and a dynamics and it changes. So the policy which made at a moment could not be appropriate to other time. We need some mechanisms to solve this problem. In this thesis, we propose asynchronous policy-based Grid resource management mechanism for maintaining consistency between policy of Grid
