Zusammenfassung:Example implementations relate to reducing control plane overload of a network device. In an example, a non-transitory computer-readable storage medium may store instructions that, when executed by a processor of an SDN controller, cause the SDN controller to track packet-in messages received from a controlled switch and, if a rate of packet-in messages received from the controlled switch exceeds a threshold, send a flow rule to the controlled switch to divert a subset of unmatched flows to a non-SDN forwarding pipeline of the controlled switch.
