I'm new in the Openflow scene but for what I understood, the controller will have to maintain a state of the requests coming from the ports, to know which rules he should add to the switch, so that the "multicast" works. The switches are dumb systems so only the controller will know what to do and only he acts. For what I know, the switches cannot reconfigure themselves.
