Hi Benjamin,

To go off onto a tangent:

	I know this is not really your question, but I think the ACKs =

too much sense to tell the sender to send more faster (which essentially =

congestion but rather increase it.=20
	There is one caveat though: when ECN is used it might make sense =
to send out the ACK that will signal the congestion state back to the =
sender faster=85 So if you prioritize ACKs only select those with an =
ECN-Echo flag ;)=20
	@bloat : What do you all think about this refined ACK =
prioritization scheme?

Best Regards
