Warren Kumari has entered the following ballot position for draft-ietf-ccamp-rsvp-te-bandwidth-availability-14: No Objection 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/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-ccamp-rsvp-te-bandwidth-availability/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I must admit that I'm having a hard time understanding the utility of this, and how exactly systems are supposed to make a reasonable decision based upon the information -- I don't **really** care that the probability of the link being at 100Mbps is 99.995%, what I care about is what the available bandwidth is *now*. When my device has a 123Mbps flow, it needs to decide what to do with it -- I get that this document describes how the bandwidth probability can be transmitted, but how should my device use this information? I'm also confused by the table: Sub-bandwidth (Mbps) Availability ------------------ ------------ 200 99.99% 100 99.995% 100 99.999% Is there an error here? I also support the DISCUSS on the floating-point issue -- perhaps this could be much more simply encoded with a table and some bits? E.G: 25%, 50%, 75%, 80%, 90%, 91%, 92%.. 99%. If > 99%, then the remaining gets used to encode the "number of nines" availability (5 == 5 nines).
