I have several users who've recently become aware of RFC1112 written by S.Deering of Stanford(1989) on Host Extensions on IP Multicasting. We're reviewing the paper for possible interest. Questions are: 1) Has any router/bridge company done this? If not, are any working on it. 2) Are there any networks supporting this at this time? Or in the future? 3) Any more interesting comments you can add to this. IP Multicasting, for those of you who'd like to know, is: [quoting from the RFC] "IP multicasting is the transmission of an IP datagram to a "host group", a set of zero, or more hosts identified by a single IP destination address". The RFC112 goes into many unique details that could make this a very flexible protocol to implement, and we'd like to know more. For those of of us with Internet DNS sites, dealing with potential DNS forgeries, this could indeed offer an additional level of complexity in the future, if many adopt it...

We (Cornell, gated) and Proteon are both working on implementing routing multicast packets in OSPF; Steve Deering's involved too. After we get that nailed down Cornell plans on building multicast support into either BGP or IDPR. although I expect the inter-administration protocols to be significantly more difficult. The algorithms are more or less worked out for doing all of this, but it'll be a while.
