
Burst Test check box when selected (cleared by default) verifies
that the expected burst size can be transmitted at maximum burst
rate with minimal loss.
CBS (Committed Burst Size) check box when selected (see SLA
Parameters on page 196), verifies the performance of a committed
burst size at CIR’s average TX rate.
EBS (Excess Burst Size) check box when selected (see SLA
Parameters on page 196), verifies the performance of an excess
burst size at CIR+EIR’s average TX rate.
The maximum Jitter, Latency, Frame Loss, and throughput are
measured. For CBS, the Jitter, Latency, and Frame Loss is
compared to the SLA thresholds to declare a pass/fail verdict. For
EBS, the throughput is compared to the SLA thresholds to declare
a pass/fail verdict.
The burst test procedure is generated for each enabled service.

Service Performance Test check box when selected (default) verifies
that the SLA parameters (see SLA Parameters on page 196) are met
over time by running multiple services simultaneously. The maximum
Jitter, Latency, Frame Loss, and average throughput are measured and
compared to the configured thresholds to declare pass/fail verdicts.
The Service Performance Test is only performed for services that have
their CIR check box selected.
Subtest Duration allows to set the duration time, in HH:MM:SS format,
for the Service Performance Test (default is 10 minutes).

Global Test Duration Estimate indicates the total estimate duration of
the test.
