Back-to-Back
Back-to-Back
The objective of this test is to find the maximum number of frames that can
be sent at maximum throughput without frame loss. A burst of frames
(
Max. time worth of frames
) is sent with minimum inter-frame gaps to the
device under test and the number of forwarded frames is counted. If the
count of transmitted frames is equal to the number of forwarded frames,
the length of the burst is increased and the test is rerun. If the number of
forwarded frames is less than the number of transmitted frames, the length
of the burst is reduced and the test is rerun. The back-to-back value is the
number of frames in the longest burst that the device under test (DUT) can
handle without the loss of any frames. The test performs the number of
defined trials (
Nb of trials to average
). The
Accuracy
and
Nb of
acceptable errors
settings specify how precise that result must be. The
test is performed for each defined frame size.
