Throughput
The objective of this test is to find the throughput of the device under test
for which there is no frame loss. Starting at the specified maximum rate
(Max. Rate), the rate converges towards the highest throughput without
frame loss. The search is done with a halving/doubling method until a final
value is reached. The throughput measurement is validated the number of
times specified (Validations) for the predefined duration (Trial Duration).
The Accuracy setting specifies how precise the result must be. The test is
performed for each defined frame size.
