Hi Lou, Thanks for your updates. I am sorry that I did not comment on the draft before, however, this is my thought, in section 3: draft>The Latency Range Data Item serves much the same purpose as the Latency Data Item defined in [RFC8175 <https://tools.ietf.org/html/rfc8175>] with the addition of being able to communicate the latency range that may be experienced by traffic on a link. AB> IMO, or understanding, latency range is not one value, but two values, so how can two values be same in the purpose of one value of latency? maybe the draft should discuss that for clarification, because I did not understand. AB> this draft does not say what will happen to the data item latency of RFC8175 (type code 16), because in RFC8175 says such messages MUST contain one value of .... and states the latency item, not the latency-range. Some sections after 12.6 does not mention the dlep support of such extension what will happen, so IMO this darft should say how the replacement of Latency item, AB> as this draft may need to say that if the extension is supported then latency range item replaces the latency item, or it may say that the maximum latency value is used into the latency item value. Not sure which approach is better. AB> My problem in understanding the draft, is that if this draft is supported as mentioned in section-12.6 in the RFC8175 then it MUST be contained in that message. So this needs to be said again I think in this draft (because the draft now says: MAY be carry). draft> The Latency Range Data Item MAY be carried in the same messages and MUST be processed according to the same rules as the Latency Data Item defined in [RFC8175 <https://tools.ietf.org/html/rfc8175>]. AB> same rules, but we have two values, one max-latency and one min-latency, please clarify, AB> as mentioned above ''same rules as latency'' but what will happen to this latency item while it is a MUST in many messages, what will be the value, but Latency range is a MAY. AB> so I may suggest the value of the range for the draft's item and that the latecy iten in rfc8175 contains the max-latency, or any you suggest to clarify it. AB> furthermore, the RFC8175 mentions change in metrics what kind of reaction, so within this draft cases, if the latency was the metric what value will be used (max, avg, min,...) may need to be specified in the draft.
