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).
