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: In one implementation, a network controller includes a path analysis module, an instruction module, and a distribution module. The path analysis module defines a data path including a plurality of network devices for a flow within a network in response to a data path request from a network device. The instruction module generates a first message including an instruction to establish a first forwarding rule at a first network device, and a second message including a first instruction to establish a second forwarding rule at a second network device and a second instruction to establish a third forwarding rule at a third network device. The distribution module provides the first message to the first network device and the second message to the second network device.

Abstract: In response to movement of a wireless device, an active tunnel between switches is dynamically included as a member of a virtual network over which the wireless device communicates, where data communicated in the virtual network is carried over the active tunnel, and where the virtual network is overlaid on an underlay physical network that includes the switches and the wireless access points.
