The Service Performance Test

Frames traveling at the CIR, then bursting to the CBS. When conducting such a test, the equipment used must also comply with specific pre-burst and post-burst gaps to ensure the token buckets are in the correct status.

Once the network configuration test is completed, service providers must confirm the network can operate under load over a configured time duration. The Service Performance Test completes this phase by generating all test flows simultaneously at the CIR for a period of time – either 15 minutes, 2 hours, or 24 hours. The time period can also be selected by the user.

Placing the network under load with multiple test flows for this time duration enables the engineer to see if other services are affecting the service under test. It also allows for statistics such as AVAIL (availability) and Un-AVAIL to be measured. With the test instrument generating each test flow and recording the IR, FTD, FDV, FLR, and AVAIL results for each frame simultaneously, test time is dramatically reduced.
