Abstract:
   Explicit Congestion Notification (ECN) is a mechanism where network
   nodes can mark IP packets instead of dropping them to indicate
   congestion to the end-points.  An ECN-capable receiver will feed this
   information back to the sender.  ECN is specified for TCP in such a
   way that it can only feed back one congestion signal per Round-Trip
   Time (RTT).  In contrast, ECN for other transport protocols, such as
   RTP/UDP and SCTP, is specified with more accurate ECN feedback.
   Recent new TCP mechanisms (like ConEx or DCTCP) need more accurate
   ECN feedback in the case where more than one marking is received in
   one RTT.  This document specifies requirements for an update to the
   TCP protocol to provide more accurate ECN feedback.
