Abstract
Provided is a method of source discovery for non-flooding multicast using OpenFlow. A data packet is received from a source address on a network device. The data packet is routed from the network device to an OpenFlow controller. The OpenFlow controller identifies a rendezvous point (RP) of the network device, maps a random address to the source address in a port used for connecting with the rendezvous point (RP), generates a flow message containing a rule for handling the data packet, transmits the flow message to the network device and adds a flow entry in the network device based on the rule for handling the data packet.
