Yes, of course. I am not a datacenter guy so this is not a problem I face,
because most of packets in my environment travel tens or hundreds of
milliseconds.
So in datacenter one wants to start marking ECN on packets very soon into
buffer depth, hoping sender will get feedback and throttle back the speed
way before one gets taildrops?
