This is a relatively new form of multicast where only one person the group can transmit. Since the source address of the transmission is known in advance, a lot of the overhead with multicast (Reverse Paths etc) is no longer necessary. To run a network with SourceSpecificMulticast, all you need to enable is PIM-SM (AddToMe: what's this?).
