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.
