Abstract:
   Explicit Congestion Notification (ECN) is an IP/TCP mechanism where
   network nodes can mark IP packets instead of dropping them to
   indicate congestion to the end-points.  An ECN-capable receiver will
   feedback this information to the sender.  ECN is specified for TCP in
   such a way that only one feedback signal can be transmitted per
   Round-Trip Time (RTT).  Recently, new TCP mechanisms like ConEx or
   DCTCP need more accurate ECN feedback information in the case where
   more than one marking is received in one RTT.  This documents
   specifies requirement for different ECN feedback scheme in the TCP
   header to provide more than one feedback signal per RTT.
