Abstract
We defined three-hierarchical information model and GNSI (Grid Network Service Interface) to reserve and activate network resources in grid environment. Management scheme of three-hierarchical information model is a little more complicated than that of existing two-hierarchical information model, but our model increases the utilization of network resources by allowing grid application to use several grid network resources over the same path. We designed and implemented grid network management system based on GNSI interface and three-hierarchical information model of network resources. We tested reservation and activation on grid network resources in the test-bed of GMPLS network overlaid over KREONET research network. We also successfully carried out international interoperability test on the control of grid network by deploying FENIUS-API over global research network.Keywordsgrid networkresource managementreservationgrid network interface
