By information, the forwarding routing of the first message is generated, and SDN to is sent first message forwarding path by message synchronization channel
Controller makes SDN controller that first message forwarding path is sent to SDN forwarding surface.
10. device according to claim 8, the VM is specifically used for VM and SDN the controller neighborhood according to foundation,
It sends its routing iinformation to SDN controller, transmits SDN controller by VM routing iinformation by the message synchronization channel
To route calculation component, so that route calculation component generates the forwarding routing of the second message according to VM routing iinformation, and pass through message
Synchronizing channel sends second message forwarding path to SDN controller, makes SDN controller that second message is forwarded road
Diameter is sent to SDN forwarding surface.
