Bob,
We plan to enable multicast for a large portion of the University of Michigan campus during 2004. We are starting with the Music School and have a half dozen other requests in process. The drivers are DVTS, Access Grid and future television services via some vendor like Video Furnace, VBrick, Cflix or Campus TeleVideo...

perhaps we could put some "how to configure mulitcast for your XXXX router" up on the wg working pages? Any volunteers willing to contribute the story on how they configured multicast?

My two cents:

Multicast is not used more often because:

1. The default condition of virtually all routers is to disable multicast.


. . .

All true, and I certainly know that multicast is not an easy thing to configure, manage and repair (or even understand!) but I'm intentionally preaching the choir here. I wasn't asking why Joe Public doesn't use multicast more often, I was asking why *we* don't use it more often.
My application, weekly recurring conference calls with a standing group of people, all at Internet2 sites, all of them advanced network users, seems like an ideal place to use multicast a/v tools - and yet, we don't. There must be dozens of similar conference calls every week; heck, Internet2 has their own conference system, and they wouldn't have bothered if they didn't use it a lot. Isn't there something wrong with that picture?
Bill.
