Virtual Network Management Based on Distributed Hybrid Network Environment

Network operation and management is a primary role of network operations center (NOC) which provides critical services for telecommunication networks, enterprise networks, campus networks, etc. Regarding hybrid research networks based on traditional IP production network and dedicated lightpath provisioning network, additional functionalities to traditional NOC facilities are required to provide special type of network services for advanced applications’ demands such as dynamic congestion-free dedicated end-to-end lightpath, virtual network operations, user-oriented network creation, etc. In particular, since advanced application experiments are performed between researchers in the multi-domain global networks (e.g. between a research lab in USA and a university in the Netherlands), new network services should provide not only reliable and dedicated quality networking but also global NOCto-NOC cooperative environment. In this paper, we suggest a framework designed for hybrid research network operations, where dvNOC scheme is proposed to meet the application requirements, which consists of distributed NOC (dNOC) and virtual NOC (vNOC).
