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 document
specifies requirements for an update to the TCP protocol to provide
more accurate ECN feedback than one signal per RTT.
