Method for providing end-to-end path on mixed networks comprising circuit and packet networks and unified software defined network controller

摘要

Disclosed is a method for providing an end-to-end (E2E) path for a composite network in which a circuit network and a packet network are mixed, and an integrated software-defined network controller for the same. The method of providing the end-to-end path using SDN technology in a composite network includes generating a path on a circuit network constituting the end-to-end path, generating a path on a packet network constituting the end-to-end path, and the shape of the circuit network and the packet network ( It may include the step of connecting the path on the circuit network and the path on the packet network using the topology) information. Therefore, by using the route providing method and the integrated SDN controller according to the present invention, it is possible to integrally provide end-to-end routes for heterogeneous networks in which a circuit network and a packet network are mixed.
