Iteration- RFC 2544 Throughput and Latency

This step, which implements an execution looping construct, corresponds to a Quick Test's Iteration entity.

The Iteration step has the following parameters:

  • duration: The duration of the test that is used to calculate the number of frames to transmit. This can be calculated in the following duration:

    • Hours

    • Minutes

    • Seconds (Default value is 30 seconds)

  • rfc2544TputIterationLoadType: The Load type used during the test iterations. Only Binary is available.

  • throughputScale: The unit of measurement for throughput and resolution. Select the throughput scale:

    • Kbps

    • Mbps

    • Gbps

      Mbps is selected by default.

  • rfc2544TputMinTput: The minimum rate of the throughput.

  • rfc2544TputMaxTput: The maximum rate of the throughput.

  • rfc2544TputInitTput: The initial rate of the throughput.

  • rfc2544TputResolution: The resolution of the iteration.

    When the Throughput Scale is measured in Kbps, the Resolution is set to 1000. In other cases, the default value is 1. The minimum value for Resolution is 1 Mbps. As and when the Throughput Scale is changed, Resolution must be redefined accordingly. For instance, when Throughput Scale is Gbps, the minimum value for Resolution is 0.001 Gbps. Please pay attention to the used scale when choosing the resolution value. The difference between the transmission rates in two consecutive iterations is compared with the Resolution value. The test stops when the difference is smaller than the value specified for the Resolution.

  • rfc2544TputAcceptablePacketLossPercentage: The acceptable loss percentage from total number of packets.
