In my context "Wireless" means "mobile" and the challenge there is that
"I lost a packet" doesn't mean "there is congestion". It most likely
means the user walked in front of a pole, the signal faded briefly, they
dropped a packet and are perfectly fine now. So in that context, tcp/ip
behaves as if it is seeing congestion when it is really seeing a
momentary loss of connectivity that comes right back as soon as the end
node moves 5 feet to the left. The right answer there might be
ubiquitous support of ECN and treating packet loss in the absence of ECN
as a connectivity issue and not a congestion issue but we are a long way
from proper ECN support.
I will have another look at the site, it has been a while since I was
