Hi Neal (and Yuchung)

 

And thanks for the presentation and many thanks for the persistent work on
this. 

CC algorithms like BBR and their MIMD-ish behavior help to solve a dilemma
with the high speed access in the new cellular 5G access, namely that the
link throughput can change quite a lot over time and that on sometimes quite
short timescales depending on mobility.

I’m looking forward to try out BBRv2 when it is available. 

 

I had one question regarding the ECN (or L4S) marking experiments. Asked it
on Jabber but not sure I understood the answer. The minRTT was quite small
in this experiment, right?. Have you done experiments with higher minRTTs
like 5ms and 10ms ?

 

Regards

/Ingemar
