Reverse Path Multicasting - (RPM) - Reverse Path Multicasting is an algorithm used by multicast routing protocols that create a delivery tree. It includes subnetworks containing group members and routers as well as subnetworks along the shortest path to subnetworks with group members. RPM makes it possible for datagrams to be forwarded along to branches that lead to members of the destination group.
