A generalized network controller in a software defined network (SDN), controlling a network with mixed switches based on different and even incompatible OpenFlow (OF) standard versions, comprising a first transceiver connected to a first OF switch comprising a first OF standard version configured to receive messages from the first OF switch and to transmit messages to the first OF switch; a second transceiver connected to a second OF switch comprising a second OF standard version configured to receive messages from the second OF switch and to transmit messages to the second OF switch, wherein the first OF standard version is different from the second OF standard version, and wherein the first OF standard version is incompatible with the second OF standard version; and a processor coupled to the first and second transceivers and configured to control the first and the second OF switches.
A generalized network controller in a software defined network (SDN), comprising:
A method for controlling a plurality of Open Flow (OF) switches corresponding to different OF standard versions in a network controller in a software defined network (SDN), comprising:
A computer program product executable by a processor in a network controller in a software defined network (SDN), the computer program product comprising computer executable instructions stored on a non-transitory computer readable medium that when executed by the processor cause the network controller to perform the following:
