Subject: [Int-dir] Intdir telechat review of draft-ietf-detnet-ip-over-tsn-05

    Reviewer: Tim Chown
    Review result: Ready with Nits

    Hi,

    Re: INT-DIR review of draft-ietf-detnet-ip-over-tsn-05

    This draft details how a DetNet IP data plane can run over a TSN sub-network.

    I have reviewed this document and believe it is Ready for publication, with
    Nits.  Note I am not overly familiar with specifics of the DetNet architecture.
    There are some hopefully simple questions that might be addressed and some
    minor editorial nits as detailed below.

    Nits:

    p.2
    Expand TSN on first use, rather than on page 4.

    p.3
    Is “6-tuple” well-defined?  Perhaps expand for clarity.

    p.4
    Is there a specific reason to show a multi-homed TSN node?
    Are there implications if it is multi homed in TSN but not IP?

    p.5
    Not being familiar with DetNet in detail it might be useful to expand on the
    rationale for mapping to multicast given the statement that the flow is
    “directed”.

    p.6
    covers required -> covers the required
    I note it says there are no requirements stated for TSN-unaware nodes in the
    document, but is it worth adding something about requirements to ensure the TSN
    Relay can be reached?

    p.7
    Implementations must -> implementation must (twice)
    FRER function -> The FRER function

    p.8
    of the document -> of this document
    challanges -> challenges
    Are member -=> are members

    p.9
    In some case -> in some cases

    --
    Tim
