Conclusion GRS and NRM allows co-allocation of both computing and network resources Network service for Grid application is demonstrated by using preliminary interface definition of “GNS-WSI” Nation-wide Grid computing is successfully demonstrated Next steps Inter-domain advance reservation and co-allocation Collaboration with Enlightened project: “Inter-domain advance reservation of coordinated network and computing resources over the Pacific”
Enhancement of GNS-WSI Promote standardization of interface to reserve bandwidth in advance
