Thanks Jan.

This should also go to the authors and XRBLOCK list,
can you take care of that, Dan?

Hi,



I have read through this draft and browsed through the related RFC7002 and 7003 used as references

with the following conclusions/observations:



Conclusion:

This document emphasis (and also RFC7002/3) is on specifying the report packet format or simply reporting some values but

not really specifying what the exported values are. Two of the metrics/values seem to be just simple counters/numbers (e.g.

not really needing more definitions), the other two are referenced to be defined in RFC7002/7003 . RFC6390 does not really

feel applicable for any of these three documents - there ought to be another document describing what all the metrics are,

defining them in RFC6390 normative format and describing how and where they are measured unless there already is another

document defining them - if so, it should be referenced here instead of 7002/7003.



Observations:

1) The term "discard burst" seems to be crucial for all the metrics but none of the three documents contains any

     definition other than just the reader's intuitive notion of its meaning

2) The two metrics "Packets Discarded in Bursts" and "Discard Count" are referenced to the same section of

    RFC7002 which contains exactly same wording as this document for "Discard Count" with no further definition.

    I am not familiar with RTP quality metrics so just assume that there could be other packet losses/packet discards

    than during the discard bursts to make the two values different.

 3)  Similarly "Total Packets Expected in Bursts" is referenced to RFC7003 with exactly same wording as this

    document - assuming that the term "discarded bursts" is a typo for "discard burst"

Hi Al, Dan,

Unless you got a queue of volunteers already, I could do that, but not really to the deadline of the 5th
- I will be off until the 4th (inc). So would be looking to Friday that week ??
