Our work is ASM but I doubt the interest group will achieve critical mass if we resrict it; so I beleive it is best that we look for commonality among related approaches. > > What is the relationship between Overlay Multicast and AMT ? > > http://www.americafree.tv/papers/draft-ietf-mboned-auto-multicast-04.txt > As I read the AMT draft, it is intended to function at the network layer. The OMcast doesn't require or even hope for any relationship with routers other than send/receive of unicast packets. > And, of course, are there any drafts to look at ? > No. Our work is mature enough to support a draft but it's not clear to me what the common basis for interoperation will be. I hope to gain insight into that from discussions on the new list.

I would prefer that the interface to the application be an open one - ours is plain IP multicast, which is about as open as you can get. Although the ConferenceXP interface is an API that looks to be proprietary from what I see on the webpage, they must have a group communications service lower in their architecture and they might be interested in defining a common standard. In any event I believe it would be a bad idea to rule out the possibility before learning what interests they may have. > > There is also > > Inter-Partition Networking for Overlay Multicast > Sauleh Eetemadi > Michigan State University > > http://www.conferencexp.net/community/library/papers/InternPartitionNetworking.pdf > As I read the abstract, this is an analytical treatment of an important part of the problem that we have been working on at GMU. Because we are experimentalists, we have implemented a working prototype and have people interested in using it; but this thesis appears to be an important contribution to the theoretical basis of routing in overlay networks. So yes it definitely fits and thats for pointing it out. Mark _______________________________________________ Omcast mailing list Omcast@ietf.org https://www1.ietf.org/mailman/listinfo/omcast
