Abstract:
1. 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: receiving at a receiver an incoming message from a first one of the OF switches, wherein at least two of the OF switches correspond to different non-compatible versions of an OF standard; translating with a processor the incoming message into a version independent message; processing with the processor the version independent message to generate a network management outgoing message to a second one of the OF switches; and translating the outgoing message into a version dependent message corresponding to a version compatible with the second one of the OF switches, wherein the version independent message comprises an abstracted message type OF_Type in an abstracted OF_Message format, wherein the incoming message and the outgoing message comprise a type selected from a group consisting of version dependent subclasses OF_Type wherein the incoming message and the outgoing message comprise a format selected from a group consisting of version dependent subclasses OF_Message
