After I submitted draft-huitema-quic-1wd-00, we started a discussion on
the possibility to compose extensions. The obvious way to do that is to
define a "time stamp" frame instead of modifying the ACK frame. As long
as both are in the same packet, we get the same measurements. The added
benefit is that time stamps could be composed with other frames too --
such as for example path responses, to measure one way delays when
evaluating multiple migration options.

Title: Quic Timestamps For Measuring One-Way Delays

Abstract:
The TimeStamp frame can be added to Quic packets when one way delay
measurements is useful. The timestamp is set to the number of
microseconds from the beginning of the connection to the time at
which the packet is sent. The draft defines the "enable_time_stamp"
transport parameter for negotiating the use of this extension frame,
and a new frame types for the time_stamped frame.



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.
