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.
