Abstract: A software-defined network (SDN) controller and its method for authenticating switches through encryption of the switches' identifiers. The authenticating method may include obtaining a data path identifier (DPID)-based authentication code, authenticating a received and encrypted session key by using the DPID-based authentication code, determining the presence of another switch having an identical DPID as that of the authenticated switch, and adding a modifier to the DPID and storing the modified DPID if indeed there is another switch with an identical DPID present.

Abstract: A system for controlling a carrier virtual network is disclosed. The system includes at least one virtual network controller for controlling resources of a carrier virtual network based on customer request information received from a customer network controller, and at least one physical network controller for controlling resources of a carrier physical network based on a service profile received from the at least one virtual network controller. The at least one virtual network controller interworks with the at least one physical network controller in a one to one, one to N (N is an integer equal to or larger than 2), or N to one correspondence.

Abstract: A software-defined network (SDN) system and method for implementing the same can construct a network having flexible network topology by abstracting switches and controllers, as well as a host connected to said switches, and controllers, thereby increasing scalability of a hierarchical SDN network. The SDN system includes a host part, an SDN switch part, and an SDN controller part.
