hi, we have had and continue to have similar problems. it seems related to how many bits we're pushing out--the more bits the greater the packet loss. seems like anytime we go over 2-2.5Mbps we start to see increasing packet loss. and increasing distortion in the audio especially. we have had some recent network hardware upgrades and don't notice this as much now, but it still seems an unknown cause. our networking people don't see this loss at all--but then maybe they wouldn't be expected to??? all our traffic goes through a packetshaper, but they've played with that without any seeming improvement. our beacon seems to indicated a mixed picture--ok to some sites, bad to others, and in some cases it says we're not even seeing ourselves! i'd be very interested in possible causes and tools for diagnosing/ confirming this behavior. thanks, =========================== Gurcharan S.

We did notice that every minute on the minute we lose packets on our display, audio, and video hosts. We are positive that we aren't seeing the packets at all because we can see with the MS Windows 2000 cpu monitor a huge drop in load, and then a resumption of the previous load. Since there isn't a spike, that seems to indicate that the packets aren't suddenly coming through all at once. It almost makes the audio unusable...at the very least it seems to strike whenever someone says something interesting. Our networking people are trying to discover what is happening, but they don't have any likely suspects. Has anyone else seen something like this? Can you help us fix this? This is a significant quality issue for us.
