A hybrid control method for a network includes operating edge switches under software defined networking control, wherein each of the edge switches is communicatively coupled to a controller for the software defined networking control; operating non-adjacent switches communicatively coupling the edge switches together under distributed control, wherein the non-adjacent switches are not coupled to the controller; and utilizing the controller to route traffic between the edge switches through the non-adjacent switches in a hybrid control scheme including both the software defined networking control and the distributed control.

Systems and methods for combined software defined networking and distributed network control

A Software Defined Networking (SDN) controller is described associated with a local domain and configured to control remote services in a remote domain. The SDN controller includes a network interface communicatively coupled to the remote domain; a processor communicatively coupled to the network interface; and memory storing instructions that, when executed, cause the processor to, subsequent to instantiation of a logical switch in a device in the remote domain, establish a control channel with the logical switch, wherein the control channel flows over the local domain and the remote domain, and control the logical switch in the remote domain via the control channel.
