Spirent TestCenter: How do I explain when using Spirent TestCenter and running RFC2544 throughput test the reason the Offered Load is substantially less that the Intended Load?

Environment/Versions

  • Spirent TestCenter

  • All Versions

  • RFC 2544

Answer

I mention when running RFC2544 the Intended Load and Offered load should be very similar.

If the Offered Load is substantially less than the offered load this may be the explanation:

When the test is configured as -> Test Parameters -> Improve Time to Test -> Skip to next load when iteration fails and when there is packet loss that causes the iteration to abruptly end, the configured rate may not tracked by the analyzer.

If this occurs and is a concern, I recommend Deselect -> Test Parameters -> Improve Time to Test -> Skip to next load when iteration fails.
