Advanced reservation and co-allocation of grid resources: A step towards an invisible grid

The grid resource management mainly concerns with provision of the Grid resources on-demand. Grid resources are heterogeneous in nature, distributed under multiple trust domains and controlled by their local management systems. In order to provide a Grid level smart and robust resource management that shields the Grid middleware complexities, we need a better control over Grid resources. A mechanism for the provision of Service Level Agreement (SLA) between resource requester and provider Could leads us to achieve this goal. Advanced reservation is a promise by the system that a certain resource capability will be available some time in future. In this paper we propose a distributed system for advanced reservation and co-allocation of the Grid resources in which clients can negotiate with resource provider for the better compromise between application requirements and resource capabilities.
