Stream
Throughput
The throughput is measured for each stream on all valid frames (valid
Throughput tag with no FCS error). The maximum, minimum, current, and
average throughput results are reported.
Unit
choices are
%
, and
Mbps
. The default setting is
%
.
Note:
For the
Current
value,
0
is displayed when no RX rate has been measured
in the last second.
Round Trip Latency
The round trip latency (delay) is measured for each stream on all valid
frames (valid Latency tag, expected originator identifier value, and no FCS
error). The maximum, minimum, current, and average delay values are
reported.
Note:
Round Trip Latency
statistics are only available in loopback test topology.
Note:
Delay measurements smaller than 15
μ
s will be discarded, not used for the
sampling process, and
“
< 0.015” will be displayed. For the
Current
value,
Not measurable
is displayed when no delay has been measured in the last
second.
Jitter
The Jitter is measured for each stream on all valid frames (in-sequence
frames, valid Jitter tag, and no FCS error). The estimated Jitter, maximum,
minimum, current, and average delay values are reported.
Note:
Delay variation measurements smaller than 15
μ
s will be discarded, not
used for the sampling process, and “< 0.015” will be displayed as the
minimum value. For the
Current
value,
Not measurable
is displayed when
no delay has been measured in the last second.
