Abstract
A Software Defined Network (SDN) includes a plurality of forwarding devices and a routing control device located separate from the forwarding devices. The routing control device, establishes paths to and from the network forwarding devices. Using such paths, forwarding devices send the routing control device information reflecting the topology if the network. Embodiments disclosed herein enable automatic discovery of the topology of the network and the paths to and from the routing control device.
