User Oriented Virtual Network Management Based on dvNOC Environment
Distributed Virtual Network Operations Center (dvNOC) presents virtualized network management framework on hybrid research networks for both network operators and endusers (e.g. researchers) to monitor and manage their own virtual networks. Another purpose of dvNOC is to meet the network demands of advanced applications on hybrid research networks, e.g. very high bandwidth, no datagram loss, almost zero jitter with strict traffic isolation. Based on hierarchical architecture consisting of dNOC (distributed NOC) and vNOC (virtual NOC), users can acquire three functionalities, multi-domain network awareness, efficient NOC-to-NOC cooperation, and user-oriented virtual network management, which are essential elements to achieve automated and virtual network management based on users, over multi-national and inter-domain hybrid research networks.
