  Subject: [xrblock] Review of draft-ietf-xrblock-rtcp-xr-summary-stat


  I took some time to review draft-ietf-xrblock-rtcp-xr-summary-stat and have the following comments:

  1. Section 1.
  s/transport layer metrics/ transport related end system metrics

[Qin]: Okay.

  2.Section 1.
  s/Group of Pictures/Group of Pictures (GOP)

[Qin]: Okay.

  3.section 2.1
  s/derivation frame/derived frame

[Qin]: Looks good to me.

  4.Section 3
  s/transport layer metrics/transport related end system metrics

[Qin]: Okay.

  5.Section 3.1.1, figure

[Qin]: Okay.

  6.Section 3.2.1, figure

[Qin]: Okay.

  7. Section 3.2.2
  The Interval metric flag of Burst Gap Discard Summary Statistics metrics block should
  be consistent with the interval metric flag of Burst Gap Loss Summary Statistics
  metrics. Therefore I propose the following change
  This field is used to indicate whether the metrics block is an

  Interval or a Cumulative report,

        This field is used to indicate whether the Burst/Gap Discard Summary

        Statistics metrics are Sampled, Interval or Cumulative metrics, that is, whether the

        reported values applies to the most recent measurement interval

        duration between successive metrics reports (I=10) (the Interval

        Duration) or to the accumulation period characteristic of

        cumulative measurements (I=11) (the Cumulative Duration) or is a

        sampled instantaneous value (I=01) (Sampled Value).


[Qin]: Okay.

  8.Section 4.1.1,figure

  9.Section 6.1
  s/Section 5.1/Section 3.1
  s/Section 5.2/Section 3.2
  s/Section 6.1/Section 4.1

[Qin]: Okay.

  10.Section 9.2
  Some references need to be updated to the latest version.

[Qin]: Okay.
