The purpose of the SAM test suite is to verify that the service is compliant to its Bandwidth Profile and Service
Acceptance Criteria. The test is broken down into two phases:
Phase 1: Service Configuration test : The services running on the same line are tested one by one to verify the
correct service profile provisioning.
Phase 2: Service Performance test : The services running on the same line are tested simultaneously over an
extended period of time, to verify network robustness.
Test Application
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.
