I can remember reading quite a few papers where a similar scheme for ect(1) was
adopted - often with additional changes on both ends to make use of this
signal. Including schemes that encoded complex information in the stream of
ect0/ect1...
Where can one find simulations of the interaction
Hi,
Disclaimer: As one of the co-authors, I can point you to
Trammell, B., Kühlewind, M., Boppart, D., Learmonth, I., Fairhurst, G.,

Had to chuckle while reading this... :)
“There is a common misperception that latency is a dominant technical
measure of performance for broadband,” Dankberg said.

Hi Jerry,
isn't this the problem statement of Conex?
Again, you at the end host would gain little insight with Conex, but every
intermediate network operator can observe the red/black marked packets, compare
the ratios and know to what extent (by looking at ingress vs egress into his
network
Aparently, Google is also looking into some form of FEC - transparant to
legacy TCP though, and potentially adaptive...
Don't have any details other an overheard conversation at some place...

traffic is much more resilient than traffic being sent
in short bursts of wirespeed trains of packets. (TSO defeats the
self-clocking of TCP with ACKs).
Just a thought...

I'm curious, has anyone done some simulations to check if the following
qualitative statement holds true, and if, what the quantitative effect is:
With bufferbloat, the TCP congestion control reaction is unduely delayed.
When it finally happens, the tcp stream is likely facing a burst loss
Heretical question: Why must the congestion notification implemented as a
(distributed) function of the network itself, and take the reaction of the
end hosts into consideration. If the signaling would only indicate the local
congestion state, but then move the reaction to that into the end
