Abstract:

How to improve the ability of a manageable and controllable communication network in supporting information grid application is studied. A service-oriented architecture of the GCN (Grid Communication Network) is presented and the key technologies of the GCN are studied. The core idea of the architecture is to increase the direct interaction between grid application and network, to provide the ability of automatic transport according to the transmission demands of grid application information, to guarantee end-to-end QoS and improve network resource utility at the same time by adding GNS (Grid Network Service) to the current communication networks. Some services of the GNS for the ATM/MPLS communication network are developped based on the policy mechanism. A GCN prototype system is constructed by integrating the GNS and the ATM/MPLS network. Demonstration results show that the architecture of the GCN proposed in this paper and the key technologies are feasible.
