SUT/DUT. Packet flow metrics are measured per direction, and can be
reported as aggregate for both directions (i.e. throughput) and/or
separately for each measured direction (i.e. latency). In most cases
bi-directional tests use the same (symmetric) load in both directions.
- **Uni-directional throughput tests**: involve packets/frames flowing in
