All things related to multicast

[Alan Crosswell <>]

So I am trying to view some sources and have been seeing the following
very consistently:

- "U0 Broadcasts NASA Videos (01)" jumps around between 30 fps and 0 fps every
  couple of seconds.  50% short term drop rate.  S= blaster.uoregon.edu

- "UW-Milwaukee" pretty consistent at 27-30 fps.  4% short term drop rate.
   S=IPTV-manager.imt.uwm.edu.  Content is like watching paint dry:-)

- "GigaPort demo" conistently 24-25 fps.  0% short term drop rate.
   S=surfnet-tv3.hvu.nl

- "CPAC on CA_net 3..." similar jumpiness to the UO session, perhaps
   even worse.  S=iptv.canet3.net

- "Window on NDSU" about 5 fps with no loss.  S=ruby.cs.ndsu.NoDak.edu and
   and rover.cc.ndsu.NoDak.edu.  Note these are lower frame rate sessions....

Could others possibly view these same sessions and compare?
Is there a better way than these subjective measurements to compare these?

It would be nice if IPTV Content Manager would stop announcing sessions
for which the "managed server" is down.  90% of the clutter in IPTV viewer
is these kinds of sessions.

PS: imj.ucsb.edu is refusing connections right now so I can't get to some
    of the tools and papers referenced off the wg web page.
