Spencer Dawkins has entered the following ballot position for draft-ietf-rmcat-sbd-11: Yes 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-rmcat-sbd/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I'm somewhat confused about whether the intended scope for this mechanism is to detect bottleneck links shared by all flows, or only what's shared by RTP media flows. The Abstract seems clear about that, but I'm not seeing a similar statement about scope in the Introduction, unless I'm missing it. Perhaps it's worth repeating the statement from the Abstract in the Introduction? I agree with the last sentence in this paragraph, The current Internet is unable to explicitly inform endpoints as to which flows share bottlenecks, so endpoints need to infer this from whatever information is available to them. The mechanism described here currently utilizes packet loss and packet delay, but is not restricted to these. As ECN becomes more prevalent it too will become a valuable base signal. and I'd believe that ECN helps identify path bottlenecks, but I'm not understanding how ECN helps identify shared bottlenecks, and I think that's the point being made here.
