----------------------------------------------------------------------
COMMENT:
----------------------------------------------------------------------

I agree with Roman about consistently (not) specifying units.

Section 5.6

Please expand "UNI".
<BV> OK. 


Section 5.9.4

Where is PLR precisely defined?
<BV> PLR packet loss ratio is defined as usually as the ratio of total lost IP packet outcomes to total transmitted IP packets in a population of interest (determined by the loss measurement interval in the DetNet case). I think this is fully inline with rfc2680/rfc7680 or definition of other SDOs like ITU Y.1540 IPLR definition or MEF 10.3.

Section 5.9.6, 6.3.6

Over what time interval is the misordering tolerance measured/applied?
<BV> Misordering tolerance is not really time interval specific. It is more a measure on the order of consecutive packets. 
If You intend to have a time interval view, then the bounded delay requirement of the flow can be treated as an interval 
during the misorder happens.

Section 7

I'm not sure what sense the word "applied" (in "applied from the user of the DeNetService") is being used.  The sentences would parse more easily if it was supposed to be "supplied", but I'm not 100% that's the intended meaning.
<BV> OK, I had no concerns on using "applied" here, but I will consult with the native English co-authors. :--))
