Abstract
In an example, a method is disclosed for implementing forwarding behavior based on communication activity between an SDN controller and a network device. The method includes generating, for the network device, a first flow table rule to implement first forwarding behavior for a network flow if communication to the SDN controller is active. The first flow table rule comprises match criteria for matching to the network flow, a first timeout value, and a first priority value. The method also includes generating, for the network device, a second flow table rule to implement second forwarding behavior for the network flow if communication to the SDN controller is not active. The second flow table rule comprises match criteria for matching to the network flow, a second timeout value, and a second priority value. The method further includes instructing the network device to implement the first and second flow table rules.
