This note describes the Explicit Congestion Notification (ECN)-nonce,
an optional addition to ECN that protects against accidental or
malicious concealment of marked packets from the TCP sender. It
improves the robustness of congestion control by preventing receivers
from exploiting ECN to gain an unfair share of network bandwidth. The
ECN-nonce uses the two ECN-Capable Transport (ECT)codepoints in the
ECN field of the IP header, and requires a flag in the TCP header. It
is computationally efficient for both routers and hosts.
This document is a product of the Transport Area Working Group of the
