Spirent TestCenter: Why does RFC-2544 show TX Rate is 99.997% instead of 100%?

  • Spirent TestCenter
    • RFC-2544
      • Test is set for 100% but results show less than 100%.
  • PPM adjustment on the port affects TX rate.
  • Be sure to set PPM adjustment to zero or just select Internal clock (w/o PPM).
  • RFC-2544 indicates the throughput reporting is to show the theoretical frame rate and the test results in frames per second.
    • Thus this relationship will determine what is the percentage of that throughput results.
