- Steve Casner and I, with much help from the good folks at CNRI, MIT and
- NEARnet, are organizing another Internet audiocast experiment (and, we hope,
- videocast and imagecast) for the upcoming IETF meeting in Cambridge. In
- order to reach a larger number of participants than last time, we are looking
- for volunteers to provide IP multicast forwarding machines and to help with
- the (mostly manual, for now) configuration task. We'd particularly like to
- get help from some of the regional and backbone network providers, because
- they are able to position the multicast relaying functions in the best
- locations, relative to their customers and to high(er) capacity links.
- It might also give them a chance to learn more about providing multicast
- service, before their customers start clamoring for it. :-)
-
- We'd also be delighted to get help from people other than network providers
- who are:
-
- o well-positioned, connectivity-wise (especially, in or to locations
- outside the U.S.),
-
- o who are willing to use one or more of their own machines as
- multicast forwarders (Sun sparcstation, DEC pmax, or Proteon
- router, running multicast routing software) for the weeks up to
- and including IETF week, and
-
- o who already have experience with the "mrouted" multicast routing
- demon or the new Proteon MOSPF code, and have no qualms about
- installing kernel patchs or new code releases on short notice.
-
- (The people who helped us out with the San Diego audiocast all qualify, of
- course!)
-
- It should be an exciting experiment. We are hoping to demonstrate compressed
- audio (to reach less bandwidth-rich parts of the Internet), low-data-rate
- video, real-time distribution of presentation slides, and new multicast
- routing protocols. But we need your help to make it happen. If you can
- help, please send me email; I will provide more details about required
- hardware and software and about the operational aspects of configuring and
- running the multicast Internet. (I'll respond after June 22, when I get back
- from travel.)
-
- For those of you who are interested in participating in the audiocast as end
- sites (i.e., non-forwarders), take a look in the vmtp-ip directory on host
- gregorio.stanford.edu for software to modify your BSD, SunOS, or Ultrix kernel
- to support IP multicast, and stay tuned to this list for information about
- getting hooked into the multicast topology and about programs to receive and
- generate audio/video/images.
