But I recollect that FORE ATM equipment using LAN Emulation (LANE) used a broadcast and unknown server (BUS) to establish a point-to-point ATM PVC for each broadcast and multicast receiver on a LAN segment. As well as being inherently unscalable (I think the BUS ran on an ASX1000 cpu), this scheme turned the single stream concept of multicast on its head, creating essentially a unicast stream for each multicast PVC client.
IIRC, plenty of popular ethernet switches do this across their backplane for multicast .. Adrian
