    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.
