Martin Duke has entered the following ballot position for draft-ietf-babel-rtt-extension-05: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/about/groups/iesg/statements/handling-ballot-positions/ for more information about how to handle DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-babel-rtt-extension/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- After discussion with the IESG and another review of the document, I understand quite a bit more and would like to withdraw most of the DISCUSS points. Ultimately, I'd just like a clearer statement that Section 4 is non-normative and nodes are free to use any method to compute RTT from samples, and cost from RTT, as that doesn't prevent convergence of the protocols. As with any Distance-vector protocol, if cost computation is not uniform you will get some silly results. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- - Is there any notion of RTT variance, jitter, or other statistical properties in this framework? ISTM to me that 20 ms RTT + 50 ms variance is a worse link than 40ms RTT + 2ms variance.
