Phase 1: Service Configuration Test
The service configuration test is broken down into three steps. The steps are tested individually for all the services delivered on
the same line.
Step 1: Committed Information Rate (CIR) Test
: Traffic is transmitted at the CIR for a short period of time and the
received traffic is evaluated against the Service Acceptance Criteria (FLR, FTD, FDV) measured simultaneously. The CIR
test passes if the measurements on the received traffic stay below the performance objectives.
Step 2: Excess Information Rate (EIR) Test
: Traffic is transmitted at the CIR+EIR rate for a short period of time; the EIR
test passes if the received traffic rate is between the CIR (minus the margin allowed by the FLR) and CIR+EIR.
Step 3: Traffic Policing (Overshoot Test)
: The purpose of the Traffic Policing Test is to ensure that when transmitting at
a rate higher than the allowed CIR+EIR, the excess traffic will be appropriately blocked to avoid interference with other
services. For this test, traffic is transmitted at 25% higher than the CIR+EIR for a short period of time. The test passes if
the received traffic rate is at least at the CIR (minus the margin allowed by the FLR) but does not exceed the allowed
CIR+EIR.
At this time the
Committed Burst Size (CBS)
and
Excess Burst Size (EBS)
tests are considered experimental and not
an integral part of the standard.
Service Bandwidth Profile
Phase 2: Service Performance Test
Services running on the same line are tested simultaneously over an extended period of time, to verify network robustness.
Service Acceptance Criteria (SAC) including Frame Transfer Delay (FTD), Frame Delay Variation (FDV), Frame Loss Ratio (FLR)
and Availability (AVAIL) are verified for each service.
