Oh goody, the whole RED, BLUE, WRED, AQM, etc menagerie.
Connections already in progress (i.e. the ones with ECN) we want to keep
working and finish. We don't want those connections to abort in the
middle, and then add to the congestion when they retry.
The phrase everyone is trying to avoid saying is "Admission Control." The
Internet doesn't do admission control well (or even badly).
