In an OpenFlow network, the various control plane functions of an L2 switch — Spanning Tree Protocol, MAC address learning, etc. — are determined by server software rather than switch firmware.

The possibilities of SDN, in particular OpenFlow, are exciting. But to see the possible become reality will depend on how quickly a capable and usable Northbound API is developed.
