Just a couple of Q's about wan link utilization:
When will the user notice the high bandwidth utilization over a wan link when running applications over the wan? If the utilization is above 30% or higher?
The same in a LAN environment, the utilization over a trunk. When will the application become slower or the user will start to complain? Will a gig trunk reporting 40-50% utilization impact the applications transporting data over the trunk or the user start to complain?
I just wonder if anyone have any experience with issues like this, or have any utilizations "guidelines" considering upgrading bandwith.
