Mirja, Thanks for you review -- apologies for not addressing everything. I had left a few things out as not necessary to change the draft, but we've now made the following changes in draft-ietf-aqm-codel-09 <https://tools.ietf.org/html/draft-ietf-aqm-codel-09>. 1) Did you also check the sec-art and gen-art review. Both, as well as some > ADs, suggested to (better) define such terms as Sojourn time, estimator, or > Interval. Would it make sense to add something to the terminology section, > or did you decide this is not needed? > We've added these definitons now in Section 2. > 2) Did you see Alia’s comments on mircoflows? I think it is true that in > some cases you may also want to use additional information like the flow > label or DSCP and not just the 5-tuple, while the text explicitly talks > about 5-tuples. Do you want to add something here, or did you on purpose > decide to only restrict to 5-tuples? I thinks this may be an unnecessary > restriction and probably was not meant to be one. > We fixed the draft to remove mentions of 5-tuples. (This was already done in -08.) > 3) Did you see this comment from Ekr: > "Following up on the above point, you must be able to > drop packets when the queue is entirely full, but S > 4.4 doesn't seem to contemplate this.

Maybe I just missed that but it > seems important. > There's nothing to be done if a packet arrives at a full buffer besides dropping it... we've added a sentence now that says "Packets arriving at a full buffer SHOULD be dropped." Hopefully that should clarify things. Hope this covers everything that's pending -- let me know if I've missed anything.
