Abstract
A control channel for routing management messages to or from an OpenFlow controller is separated from a reserved port within a data channel for routing unknown data packets to or from the OpenFlow controller. The port may be reserved by setting a reserved port flag. A packet routing table may include a table miss entry that indicates the unknown packets should be routed via the reserved port. By utilizing the reserved port to route unknown packets, the unknown packets do not traverse into the control channel, and the separation of the OpenFlow control channel from the OpenFlow data channel is enhanced.
