This looks to be in good shape. Some minor points I noticed:

- The last paragraph of the definition of the Interval Metric Flag in Section 3.2 might be clearer written “Burst/Gap Discard Metrics can only be measured over definite intervals, and cannot be sampled. Accordingly, the value I=01, indicating a sampled value, MUST NOT be used.”

[Qin]: Good proposed change, thanks.

- For Packets discarded in bursts and Total packets expected in bursts, why are the values 0xFFFFFE and 0xFFFFFF listed as SHOULD? If there is a case where the condition is satisfied by the listed value isn’t reported, then this needs to be documented; otherwise the draft ought to say MUST instead.

[Qin]: Accepted, we will use MUST.

- Section 3.3 reads as-if some new metrics are going to be defined, but all it actually does is reference another draft. I wonder if those summary metrics shouldn’t be defined in this draft, and if the split of related metrics into a separate draft is worthwhile in this case?

[Qin]: Okay, it looks no harm to remove section 3.3.
