Michael,
I think the most productive thing would be to give us some overview of
how multicasting works relative to things like polycom or webcasting.
Something we can use to explain it to a user. Then show us how to
troubleshoot various problems we've encountered and what info our
network admins need in order to solve problems.
I've made good use of the Abilene Looking Glass:
http://www.accessgrid.org/agdp/guide/looking_glass/1.0/book1.html
<http://ratt.uits.iu.edu/routerproxy/abilene/>
Are there other tools, tips, tricks we can use to figure out where the
problem is?
One of the biggest problems I have is that by the time I collect the
info on a problem and contact my net admins and they get back to me, the
meeting ends and everyone disappears. I'd like to be able to pinpoint
the problem and be able to go to my net admin and say "Please fix X" and
that be it.
