Communication device with persistent configuration and verification

Patent ·
OSTI ID:1532052
; ;
The present disclosure pertains to systems and methods for establishing communication with a remote communication device in a software defined network (SDN) during time when an SDN controller is unavailable. In one embodiment, a local communication device may be configured to receive a plurality of data flows from an SDN controller and to store the plurality of data flows in a persistent data memory. The device may generate a unique identifier for the local communication device that is transmitted to a remote communication device. Following a disruption the results in the SDN controller being unavailable, the local communication device may recover into a default configured state based on the plurality of data flows in the persistent data memory. The local communication device may then transmit the unique identifier to the remote communication device after the disruption to begin a process of reestablishing communication with the remote communication device.
