SDN DOMAIN CONTROLLER SDN NETWORK SYSTEM AND METHOD FOR MANAGING THEREOF

摘要

According to the present invention, a method for managing a software defined network (SDN) system in a domain controller comprises the steps of: transmitting domain network information corresponding to a corresponding domain and a plurality of LSR switches connected thereto to an upper controller; requesting the upper controller to generate a multi-segment pseudo-wire; and transmitting available bandwidth information corresponding to the domain network information to the upper controller as the multi-segment pseudo-wire is generated by the upper controller.
