Abstract

A method for controlling an underlying physical network by a software defined network includes providing a physical network that comprises routers for routing data traffic on a data communication plane, providing a software defined network that comprises at least one controller and at least one feature on a control plane for controlling the data forwarding elements of the physical network, communicating, by the data forwarding elements of the data communication plane, with the controller of the control plane on a dedicated control channel, communicating, by the controller, with the at least one feature on a dedicated feature channel in the control plane, and exchanging, via the data communication plane, at least a portion of the data traffic in the control plane.
