Detailed Description

Demonstration of a Learning controller. When a connected switch passes it a packet the switch doesn't recognize, the controller delves into its learned states and figures out if we know what port the packet is supposed to go to, flooding if unknown, and adjusts the switch's flow table accordingly.
