Hi tcpm & iccrg,

We are proposing a new TCP timestamp option to measure the network delay
more precisely (e.g. excluding delayed ACK effects) for congestion control,
e.g. Swift published SIGCOMM 2020. The precision of the measurements can
potentially be further enhanced by NIC hardware timestamps. We are working
on a reference implementation for Linux as well.

We'll also present it in the upcoming tcpm meeting. Feedbacks are very
welcome.

Abstract:
   This document presents ETS: an Extensible TimeStamps option for TCP.
   It allows hosts to use microseconds as the unit for timestamps to
   improve the precision of timestamps, and advertise the maximum ACK
   delay for its own delayed ACK mechanism.  Furthermore, it extends the
   information provided in the [RFC7323] TCP Timestamps Option by
   including the receiver delay in the TSecr echoing, so that the
   receiver of the ACK is able to more accurately estimate the portion
   of the RTT that resulted from time traveling through the network.
   The ETS option format is extensible, so that future extensions can
   add further information without the overhead of extra TCP option kind
   and length fields.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
