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

Thank you for the work put into this document. From a purist point of view, I appreciate to see this document being published as "informational" and *before* the data models.

Please find below some non-blocking COMMENT points (but replies would be appreciated), and some nits.

I hope that this helps to improve the document,

Regards,

-éric

== COMMENTS ==

In general and may be I missed it, but I see no relationships between the three information models (app/flow/service) and relationships among entities are also quite an important part of information models.

-- Title --
The title is only about "flow" but the abstract and content are about "flow and services". Strongly suggest to update the title.
<BV> OK.

-- Section 1 --
Should "IP 6-tuple" have a reference? I guess that this is about the common 5-tuple + DSCP but a definition will be welcome (or add a reference to section
5.4.2)
<BV> OK. Reference to RFC8939 is added.

Adding a reference to IEEE 802.1 TSN ?

-- Section 1.1 --
I am puzzled by this sentence "herefore, the DetNet flow and service information models described in this document are based on [IEEE8021Qcc]"...
Does one information model supersede or contradict the other one ? Else, why redo the work at the IETF? It is partially answered in section 1.2 but still unclear to me.
<BV> No, the models do not supersede or contradict. They have similarities but IEEE work focus only on Layer-2 and deals with TSN Streams. IETF work was needed for Layer-3 (DetNet flows).

-- Section 5.2 --
Is the list strictly limited to Ethernet, MPLS, and IP ?
<BV> Yes.

-- Section 6.3.3 --
Isn't the word 'jitter' more common than 'Maximum Latency Variation' ?
<BV> Aaahh. That was the result of a long terminology discussion. We have intentionally avoided using the term jitter.

-- Section 6.3.5 & 6.3.6 --
Missing the unit ?
<BV> It is simple number of packets.

== NITS ==

-- Section 2.3 --
To respect the convention of the previous sentence, I would have expected that "SourceMacAddress" would be written as "SourceMACAddress" as "MAC" is an acronym ;-)
<BV> OK. For consistency with IEEE TSN documents we have used the TSN naming conventions. So I would keep it in its current form.

-- Section 5 --
s/with fix packet size/with fixed packet size/ ?
<BV> OK, thanks.

-- Section 5.1 --
s/many to one/n:1/ to be consistent ?
<BV> OK, thanks.
