Bottlenecks and link upgrades

Wed Aug 12 15:08:37 UTC 2020

Just my curiosity. May I ask how we can measure the link capacity loading?
What does it mean by a 50%, 70%, or 90% capacity loading? Load sampled and
measured instantaneously, or averaging over a certain period of time
(granularity)?

These are questions have bothered me for long. Don't know if I can ask
about these by the way. I take care of the radio access network performance
at work. Found many things unknown in transport network.

Thanks and best regards,
Taichi
