LEDBAT was probably my first concern and area of research before
entering this project full time. I *knew* we were going to break
ledbat, but the two questions were: how badly? (ans: pretty badly) and
did it matter? (not that much, compared to saving seconds overall in
induced delay)
LEDBAT is about more than just reducing the delay caused by the steam -
it's also about the bandwidth impact. AQM solves the delay situation,
but breaks the bandwidth reduction that LEDBAT can achieve today when
other traffic is present.
while we have long recommended CS1 be set on torrent, it turns out
that a lot of gear actually prioritizes that over BE, still. It helps
on the outbound where you can still control your dscp settings. Many
torrent users have reported just setting their stuff to max outbound
and rate limiting inbound, and observing no real effects on their link.
Do you have examples of the gear that prioritizes CS1 over best effort?
How often have you seen it? Did you see it in places where it would be
important?
