No, but I will have a hunch. I don't need to *know*, I need to have a decent
probability of being right.
what happens if the wrong hint is given? (either accidently or maliciously)
Then you get IW10 instead of IW4. Right now if I am correct, Google does IW10
all across the board.
What is the problem with making this assumption? Why should we try to change
every device on the Internet to provide this information instead of just using
this as the default?
The approach of starting slow and ramping up works well, except in the case
where you have lots of very short connections. So I don't see a benefit of
trying to hint slowness. There may be some value in hinting for faster
ramp-ups, but what will that do to fairness with existing systems?
In my world, core network congestion isn't something that is permanent and
continous, but an anomaly. So since the only port that should be congesting
is my access port, I don't care about fairness.
Well, you are asking for the entire Internet to be changed, so your proposal
needs to account for the rest of the Internet outside of your world. And there
we do have to worry about fairness.
