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

    Reviewer: Tim Chown
    Review result: Ready with Nits

    Hi,

    Re: INT-DIR review of draft-ietf-detnet-mpls-over-tsn-06

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

    I have reviewed this document and believe it is Ready for publication, with
    Nits, as listed below.

    Nits:

    p.2
    Loss rates -> loss rate
    Provides congestion -> provide congestion
    For MPLS-based -> for an MPLS-based

    p.3
    Include MSRP and RSVP-TE?

    p.4
    And resources -> and resource

    p.5
    >From MPLS -> from the MPLS
    Does not -> do not
    In case of -> In the case of

    As per the IP doc, not being familiar with DetNet in detail it might be useful
    to expand on the rationale for mapping to multicast given the “directed” flow.

    p.7
    As per the IP doc, I note it says there are no requirements stated for
    TSN-unaware MPLS DetNet nodes in the document, but is it worth adding something
    about requirements to ensure the TSN Relay can be reached?

    p.8
    Implementations -> implementation

    P.9
    of the document -> of this document
    challanges -> challenges
    Are member -=> are members
    Single hop -> a single hop
    In some case -> in some cases

    P.10
    Regarding the more complicated triggering for TSN-unaware nodes, should further
    text be added about this?

    --
    Tim
