A Resource Exchange Mechanism for Peak Load Management in InterGrid Environments

The potential of the Grid computing paradigm has led to the creation of several regional and national Grid environments. These environments are, however, like “Grid islands” with no resource sharing between them. We have presented an architecture to enable internetworking of Grids for resource sharing based on peering arrangements between Grids. This architecture and related mechanisms and policies are termed as the InterGrid. In this paper, we address the problem of resource exchange in InterGrid environments. Enabling resource exchange in InterGrids is a challenging task: a Grid can benefit from internetworking with other Grids but needs to respect its local user communities. The paper describes a peak load management mechanism and related policies for resource exchange between Grids using a resource share model. We demonstrate that gateways with provisioning rights over the resources of a Grid can interact with one another by using the proposed mechanism, enabling resource exchange while satisfying the requests of local user communities.
