5.4.1.4 Throughput, Latency, Frame Loss, and Burst Settings

The RFC 2544 test suite allows the user to run all four tests, one of the four tests, or a combination of any of the four tests. The user

simply has to enable/disable which tests to perform by checking/unchecking a selection box in the respective tab for each test. By

default all four tests are enabled.

The following parameters must be configured before running the RFC 2544 conformance test suite.

Throughput tab

Max Rate:

Up to 100% of the negotiated line rate. The default value is 100%.

This is the maximum transmit rate to perform the throughput test for each test frame size.

The user may configure this rate as a % of the total line rate or in Mbps. For example if the user configures the Max

Rate to be 90% and the negotiated line rate of the link is 100Mbps, then the maximum transmit rate will be 90Mbps or

90% of the line rate.

Resolution:

Input any value between 0.001% and 1%. The default value is 1%. Resolution refers to the resolution in

searching for the throughput rate. If 1% is selected, the throughput rate will be searched with ±1% accuracy.

Duration:

5 to 999 seconds. The default value is 20 seconds.

The duration is the amount of time the throughput test is run for, for each frame size at a given rate.

Frame Loss Limit (%):

Configures the frame loss tolerance used in the throughput rate search algorithm. If the frame loss

count stays below the configured Frame Loss limit, the throughput rate search will stop, otherwise the throughput rate search

will continue to the next step.
