and averaged. Results from failed throughput tests are discarded. The latency results
from the highest successful throughput test are kept and reported. Latency results as
a function of frame size and throughput are tabularized.
Frame Loss Rate
The frame loss rate test plots the frame loss as a function of utilization. Similar to
the throughput test, the test begins at 100% frame rate by sending a predetermined
number of frames, and recording the percentage of lost frames. The bandwidth is
reduced by a preset amount, 10% or less, and the test is repeated. If two successive
trials result in no frame loss, the lower rates are not tested and assumed to have
zero frame loss. This test is repeated for each frame size.
