1. A method implemented by an OpenFlow (OF) adaptor positioned between an OF controller and a Non-OF (NOF) Network Element (NE), comprising:
- transmitting, by a transmitter of the OF adaptor, a discovery message to the NOF NE in a NOF format;
receiving, by a receiver of the OF adaptor, a reply message from the NOF NE in the NOF format; and
translating, by a processor coupled to the transmitter and the receiver, the reply message to an OF format based on a predetermined set of message relationships stored in the OF adaptor.

Abstract
A method implemented by an OpenFlow (OF) adaptor positioned between an OF controller and a Non-OF (NOF) Network Element (NE) (NOF NE), comprising transmitting, by a transmitter of the OF adaptor, a discovery message to the NOF NE in a NOF format, receiving, by a receiver of the OF adaptor, a reply message from the NOF NE in the NOF format, and translating, by a processor coupled to the transmitter and the receiver, the reply message to an OF format based on a predetermined set of message relationships stored in the OF adaptor.

7. A method implemented in an OpenFlow (OF) controller comprising:
-
receiving, by a receiver of the OF controller from a Non-OF enabled network element (NOF NE) via an OF adapter, link data indicating a link between an OF enabled network element (OF NE) and the NOF NE; discovering, by a processor coupled to the receiver, network topology in a hybrid network comprising the OF NE and the NOF NE based on the link data, and storing, by a memory coupled to the processor, the discovered hybrid network topology in a network information base. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. An OpenFlow (OF) adaptor comprising:
-
a physical OF port configured to communicate with an OF controller; a physical Non-OF (NOF) port configured to communicate with a NOF Network Element (NE); a memory configured to store a predetermined set of message relationships; a transmitter coupled to the OF port, and the NOF port, and configured to transmit a discovery message to the NOF NE in a NOF format; a receiver coupled to the OF port, and the NOF port, and configured to receive a reply message from the NOF NE in the NOF format; and a processor coupled to the memory, the transmitter, the receiver, the OF port, and the NOF port, and configured to translate the reply message to an OF format based on the predetermined set of message relationships stored in the OF adaptor. - View Dependent Claims (16, 17, 18, 19, 20)
