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
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.
