I believe that I have eno= ugh information. The main objective for me was to get an understanding how = serious the issues that various boxes in the middle (e.g NATs/FWs ) mess wi= th the ECN bits really is. Seems to me, based on the info I received thus f= ar that this is becoming more and more an non-issue ?.=20 Realized that I have seen the below paper before, somehow I mixed it up wi= th the older paper, have to blame it on my own teflon-memory ...
