Abstract
The present disclosure pertains to systems and methods of handling Address Resolution Protocol (ARP) responses in a software defined network (SDN). In one embodiment, a system may comprise a controller in a control plane to generate an address store comprising information associated with a plurality of devices in communication with the SDN. The controller may also program a plurality of network devices in a data plane based on a plurality of communication flows. The network devices may forward traffic according to the plurality of communication flows received from the controller. The network device may also receive: a request from the first device for information associated with the second device, determine that the first device is authorized to communicate with the second device based on the plurality of communication flows, and generate a response to the request comprising the information associated with the second device based on the address store.
