The problems that multicast solves are also solved by the favorite solution of business: buy your way out of the problem. Bigger fatter pipes. More bandwidth. Beefier routers. The problems have been addressed (papered over) by an alternate -easily implementable- but not superior algorithm. > Kind of sounds like > QoS, and maybe there's a lesson there (20 years of research and > IETF activity, yielding, well, what?). 2.

I do think, however, that we've all gotten it quite wrong since the beginning. Multicast is not a subset of IP. It is IP. With a different view of the protocol, unicast IP is a multicast group of 2. Broadcast is a multicast group of all... perhaps if the infrastructure reflected that from the get-go, we wouldn't be in this situation. Peace, Petr
