Hi Dave,
=
Thanks for the mention of iperf 2=2E I want to= clarify that the tooling over the last many years has a focus on ultra low= latency both in metrics and mechanisms=2E Bufferbloat is supported mostly = as a rating through the use of synthetic traffic and Little's Law=2E David = Reed had pointed out that synthetic traffic does not match real world traff= ic, which comes from chaotic distributions and might be infinite in the pos= sibilities (though maybe less than infinity squared=2E)
