Proposed standard

This document has inter-IETF Areas and inter-SDO impact, most notably
with IEEE, and having this document be an IETF consensus document is
therefore considered highly important.

Yes

    This document provides the overall Architecture for Deterministic
    Networking (DetNet) which provides a capability for the delivery of
    data flows with extremely low data loss rates and bounded latency.
    DetNet operates at the IP layer and delivers service over
    sub-network technologies such as MPLS and IEEE 802.1 TSN.

Nothing particular worth noting.

The document is the foundation for other DetNet WG activities.  It has
been reviewed and discussed by many, including the WG technical advisor
who is also TSV WG co-chair.  Multiple organizations have stated that
they are working on developing DetNet solutions and early solutions
based on the principles described in this document have been
demonstrated.

I have reread this document as it progressed as well as in its final
form.  All significant technical comments were discussed publicly,
some minor and more editorial comments were also provided privately.
All identified comments have been addressed prior to publication
request.  The document is ready for publication.

No.

The group felt that review from the TSV area was critical.  WG
discussion led to contacting the TSV AD and the appointment of the TSV
WG co-chair as DetNet WG advisor.  David reviewed this document and his
comments were addressed prior to publication request.

No concerns.  This document is critical to the WG and is ready to be
published.

yes Authors/contributors know of none, see

There is an IPR disclosure from a non-wg participant on the pre-WG ID:
https://datatracker.ietf.org/ipr/search/?submit=draft&id=draft-ietf-detnet-architecture

There were no concerns raised during WG acceptance of the document.

Very solid.  The document is mature and has been discussed often.  It
was not published earlier in order to ensure the protocol solutions
being defined in the WG would not necessitate any changes in the
architecture.  The solution work has progressed to the point that
publications of this document makes sense.
