Abstract
Some embodiments provide a novel method for efficiently assigning replication-multicast network addresses to overlay-multicast groups of machines executing on host computers of a software-defined network (SDN). For a source machine that is a source of one or more multicast flows, an SDN controller receives from the source machine an overlay-multicast group network address of an overlay-multicast group for which the source machine is the source, and an overlay-multicast source network address associated with the source machine. The SDN controller uses the overlay-multicast group and source network addresses to determine a replication-multicast network address for the overlay-multicast group. The replication-multicast group network address is determined using both the overlay-multicast group and source network address to avoid different overlay-multicast groups being assigned a same replication-multicast network address. The source machine uses the replication-multicast group network address to forward the multicast flows to destination machines that are members of the overlay-multicast group.
