Abstract
This disclosure pertains to identifying a host using parallel redundancy protocol (PRP) and properly configuring communication circuits for the device in a software defined network (SDN). In one embodiment, a system includes a network in communication with a first communication host and a second communication host, the network comprising a plurality of switches interconnected with a plurality of physical links. An SDN controller in communication with the network includes a PRP identification subsystem to identify PRP traffic from the first communication host and destined for the second communication host. The SDN controller generates a first address resolution protocol (ARP) message directed to the second communication host and receive a first response from the second communication host to the ARP message that conforms to PRP. Based on the response, a traffic routing subsystem provisions communication flows between the first communication host and the second communication host to route PRP traffic.
