Abstract:
This document specifies an TCP option to get accurate Explicit
Congestion Notification (ECN) feedback from the receiver. 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 feedback
information in the case where more than one marking is received in
one RTT. This TCP extension can be used in addition to the classic
ECN as well as with a more accurate ECN scheme recently proposed
which reuses the ECN bit in the TCP header.
