The problem with CAKE/FQ and background traffic is that it can't tell if
there is congestion or not, and things like LEDBAT can't backoff and try
to avoid causing congestion. So your previous email about allowing some
congestion to take place on LE would be good as then protocols that try to
avoid causing congestion would have a way to do so.
I do not like that the standard allows for total starvation. I would
prefer it had a minimum of 5%.
I fully agree, and that would work even if all LE traffic was put into
single queue with 5% of total bw, and even if that had a 1 second FIFO
with tail drop.
