> The ECN field was never intended to be used as a classifier, except to distinguish Not-ECT flows from ECT flows (which a middlebox does need to know, to choose between mark and drop behaviours).  It was intended to be used to convey congestion information from the network to the receiver.  SCE adheres to that ideal.

Each PHB has a forwarding behaviour a DSCP re-marking behaviour and an 
ECN marking behaviour. The ECN field is the claissifer for the ECN 
marking behaviour.
