Rate and data volume are different measurements

Throughput describes data per unit time while volume describes accumulated data.

Use sustained throughput for transfer estimates

A nominal interface rate can be higher than a real end-to-end transfer rate.

Bandwidth sharing is a scenario, not a guarantee

Equal division is a simple model for multiple active users.

Estimate packet rate from average packet size

Packet-processing load depends on packet count as well as bit rate.

Interpret link utilization carefully

Average utilization can hide short peaks.
