Packet Loss on MBone from NANOG/Tampa

  • From: Eric Kozowski
  • Date: Thu Jun 05 12:26:09 1997

I'm seing high packet loss on the MBone for the NANOG session.  Anybody
know when/if this will be fixed?

It appears that the bulk of the packet loss is at  paloalto-mbone1.bbnplanet.net
with quie a bit more at maew-mbone.nsn.nasa.gov.
