Abstract:
Methods and systems presented herein provide for self-routing multicast. In one embodiment, a method includes receiving, using a switch controller, a multicast data stream join request from a source in a network, and creating, using the switch controller, a multipath identifier (ID) for a multicast data stream. Moreover, the method includes creating, using the switch controller, path identifiers (IDs) for intermediate switches in the network based on a local network topology database. Each path ID is associated with an output port bitmap. The method also includes transmitting, using the switch controller, the multipath ID and a path ID to a source of the multicast data stream, the path ID corresponding to the source of the multicast join request. Also, the multipath ID and the path ID are configured to allow the source of the multicast data stream to determine an output port mapping for a packet.
