Sequence Tracking

Out-Of-Sequence (OOS) is declared when a valid packet has its
sequence number smaller than the previously received packet.
Seconds, count, rate, and percentage values are reported. The
Out-Of-Sequence will not be considered in the global verdict.

Frame Loss is declared when a sequence number is missing. Note
that the reported value is the maximum percentage of Frame Loss
from all the burst sequences and ramp steps excluding the CIR+EIR,
EBS, and Traffic Policing steps. Seconds, count, rate, and percentage
values are reported. The pass
or fail verdict is also displayed.
RX Rate
The RX Rate (throughput) is measured for each stream on all valid frames.
The maximum, minimum, current, and average RX rate results are
reported. The pass
or fail verdict is also displayed for the average RX
rate.
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.
Jitter
The Jitter is measured for each stream on all valid frames. The estimated
Jitter, maximum, minimum, current, and average delay values are
reported. The pass
or fail verdict is also displayed for the maximum
jitter.
Note: Delay variation measurements smaller than 15 μs 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.
