Abstract
An illustrative example software-defined network (SDN) switch includes a switch portion including an input port for receiving at least one packet. The switch portion includes an output port for forwarding the at least one packet. The switch portion includes at least one stored rule. The switch portion forwards the at least one packet based on the at least one stored rule based on a determination that the packet is of a first type corresponding to the stored rule. A controller cache includes information indicating how the switch portion should forward the at least one packet based on a determination that the packet is of a second type that does not correspond to the at least one stored rule. The switch portion communicates with the controller cache to obtain an indication of how to forward the packet based on a determination that the packet is of the second type.
