SYSTEM AND A METHOD FOR OPERATING A NETWORK BASED ON NETWORK VIRTUALIZATION CAPABLE OF ESTABLISHING A VIRTUAL NETWORK USING A DOMAIN NAME

摘要

PURPOSE: A system and a method for operating a network based on network virtualization are provided to obtain the scalability and flexibility of a virtual network with a virtual network discrimination method based on a network service.;CONSTITUTION: A network operating device comprises an operation interface part (210), a resource management part (220), a virtual network control part (230), a virtual network configuration specification database (240), and a virtual network profile database (250). The resource management part manages network resources. The virtual network control part forms multiple virtual networks discriminated by domain names and sets a representative virtual router of each virtual network. The virtual network control part sets representative routing information including the IP address of each representative virtual router in a virtual router contained in each virtual network. The virtual network configuration specification database stores the IP address of each representative virtual router corresponding to the domain names. The virtual network profile database stores the profile of each virtual network.;COPYRIGHT KIPO 2013;[Reference numerals] (210) Operation interface part; (220) Resource management part; (230) Virtual network control part; (240) Virtual network configuration specification database; (250) Virtual network profile database
