As I said, there are two possibilities
1. if you mark packets sooner than you would drop them, advantage non-ECN
2. if you mark packets and don't drop them until higher levels, advantage ECN,
and big advantage to fake ECN
3: if you have flow isolation with drop-from-longest-queue-on-overflow, faking
ECN doesn’t matter to other traffic - it just turns the faker’s allocation of
queue into a dumb, non-AQM one. No problem.
so if every flow is isolated so that what it generates has no effect on any
other traffic, what value does ECN provide?
and how do you decide what the fair allocation of bandwidth is between all the
threads?
