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. ---------- Forwarded message --------- From: <internet-drafts@ietf.org> Date: Mon, Nov 2, 2020 at 3:29 PM Subject: New Version Notification for draft-yang-tcpm-ets-00.txt To: Eric Dumazet <edumazet@google.com>, Yuchung Cheng <ycheng@google.com>, Neal Cardwell <ncardwell@google.com>, Kevin Yang (Yudong) <yyd@google.com> A new version of I-D, draft-yang-tcpm-ets-00.txt has been successfully submitted by Kevin (Yudong) Yang and posted to the IETF repository. Name: draft-yang-tcpm-ets Revision: 00 Title: TCP ETS: Extensible Timestamp Options Document date: 2020-11-02 Group: Individual Submission Pages: 13 URL: https://www.ietf.org/archive/id/draft-yang-tcpm-ets-00.txt Status: https://datatracker.ietf.org/doc/draft-yang-tcpm-ets/ Htmlized: https://datatracker.ietf.org/doc/html/draft-yang-tcpm-ets Htmlized: https://tools.ietf.org/html/draft-yang-tcpm-ets-00 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. The IETF Secretariat
