Abstract: Examples disclosed herein relate to selecting an optimal network device for reporting flow table misses upon expiry of a flow in a software defined network, comprising. An SDN enabled device is selected, from a plurality of software defined network (SDN) enabled devices, for reporting a flow table miss upon expiry of a flow to an SDN controller, based on a pre-defined factor.

Abstract: This disclosure is directed to a method, system, and device for disabling links within a computer network based on a loop link priority parameter. The method includes detecting a loop in a network in a network communication device having multiple interfaces associated with different priorities. The device may transmit a first network packet as a loop check packet outbound from the network communication device via a first interface port. The device may then receive a second network packet (which may be the first outbound packet returning inappropriately to the device) as an inbound network communication via a second interface port. If the device identifies return of a sent loop check packet, it may disable one of the first interface port or the second interface port based on a comparison of loop link priority parameters to remove the loop in the network.
