Hey folks, I'm sure to you it's peanuts, but I'm a bit puzzled (most likely
because of the lack of knowledge, I bet).
I'm buying an IP backbone from VNZ (presumably MPLS). I get a MLPPP hand off
on all sites, so I don't do the actual labeling and switching, so I guess
for practical purposes what I'm trying to say is that I have no physical
control over the other side of my MLPPP links.
When I transfer a large file over FTP (or CIFS, or anything else), I'd
expect it to max out either one or both T1, but instead utilization on the
T1s is hoovering at 70% on both and sometimes MLPPP link utilization even
drops below 50%. What am I'm not gettting here?
Tx,
Andrey
