Loss detection and congestion control fundamentally involve consumption of
signals, such as delay, loss, and ECN markings, from unauthenticated
entities. An attacker can cause endpoints to reduce their sending rate by
manipulating these signals; by dropping packets, by altering path delay

A sender can detect suppression of reports by marking occasional packets that it
sends with an ECN-CE marking. If a packet sent with an ECN-CE marking is not
reported as having been CE marked when the packet is acknowledged, then the
sender can disable ECN for that path by not setting ECT codepoints in subsequent
packets sent on that path {{!RFC3168}}.
sender can disable ECN for that path by not setting ECN-Capable Transport (ECT)
codepoints in subsequent packets sent on that path {{!RFC3168}}.

Reporting additional ECN-CE markings will cause a sender to reduce their sending
rate, which is similar in effect to advertising reduced connection flow control
limits and so no advantage is gained by doing so.

Endpoints choose the congestion controller that they use. Congestion controllers
respond to reports of ECN-CE by reducing their rate, but the response may vary.
Markings can be treated as equivalent to loss ({{!RFC3168}}), but other
responses can be specified, such as ({{?RFC8511}}) or ({{?RFC8311}}).
