Abstract
Systems and methods for discovery of a controller in an OpenFlow network may include using an OpenFlow capable switch to discover the controller without the help of other components, such as DHCP. The link discovery protocol may be configured on the switch and the discovery process may use an out-of-band or an in-band communication. In one example, a link discovery protocol packet is sent out of all ports of a switch that meet the eligibility criteria. The response is guaranteed because of a TTL like mechanism in the packet. Each port on a switch that receives this link discovery protocol packet takes an action depending on its current state.
