1. Summary
The document shepherd is Michael Tüxen <tuexen@fh-muenster.com>.
The responsible Area Director is Mirja Kühlewind <ietf@kuehlewind.net>.
The recently published RFC 8311 (Relaxing Restrictions on Explicit Congestion
Notification (ECN) Experimentation) allows a TCP sender to react to an ECN
signal in a different way than to a inferred loss signal if the behaviour is
documented in an experimental RFC. This document describes such an experiment
in which the reduction of the congestion window in response to an ECN signal is
smaller than in response to an inferred packet loss. Therefore the TCPM working
group requests publication as an experimental document.
2. Review and Consensus
The document has been discussed several times in working group meetings without
any major controversy. There were also no substantial problems reported during
the working group last call and it is implemented for FreeBSD (the code has
been committed to the FreeBSD code base). The risk of running this experiment
is relatively low, since the reaction to a loss is not changed. There is very
strong consensus in the TCPM working group that this document should be
published.
