Hopefully we will be able to obtain comparative test results, using the same test scripts as we use on SCE, and also insert an RFC-3168 single queue AQM into their network to demonstrate what actually happens in that case. I think that the results will be illuminating for all concerned.

I know the experts here deems this not even a theoretical concern, but I really really want to see data, that L4S flows will not crowd out the more reactive RFC3168 flows in that situation. This is the set-up quite a number of latency sensitive end-users actually use to "debloat" the internet and it would be nice to have real data showing that this is not a concern.
