Informational

This document provides an overall framework for the DetNet data  plane, without
specifying normative behavior; there are accompanying drafts for each of the
data plane technologies (IP, MPLS, TSN) which provide the normative aspects of
the use of each of these technologies, as well as their interaction (e.g.
"DetNet MPLS over UDP/IP").

This document provides an overall framework for the DetNet data plane.  It
covers concepts and considerations that are generally common to any
Deterministic Networking data plane specification.

Nothing specific to this Framework draft.

DetNet is based on well-known IETF protocols (IP, MPLS) which are used without
modification. At this time there are no shipping implementations of DetNet per
se.

> Have a significant number of vendors indicated their plan to
>   implement the specification?

Several major vendors have been core to the development of DetNet, including
Cisco, Huawei, and Ericsson so it is assumed that they plan to implement it.

The DetNet WG (including David Black, DetNet Technical Advisor) have made
extensive reviews of the present drafts. A dedicated Data Plane Design team
have met informally, regularly, to review and progress the set of data plane
drafts. Preceding the WG decisions to use IP and MPLS for the DetNet Data
Plane, an extensive review of candidate technologies was done by Jouni Korhonen
and team (draft-ietf-detnet-dp-alt).

I have reread this document as it progressed as well as in its final
form.  All significant comments have been addressed. The document is
ready for publication.

No.

No. As an Informational document, requirements for external review of this
Framework draft are less extensive compared with the Normative DetNet Data
Plane drafts which will be submitted for publication in conjunction with this
draft.

No concerns.  This document is ready to be published.

Yes, authors/contributors know of none, see
https://mailarchive.ietf.org/arch/msg/detnet/pSxhsg-p6RUVc8GeBFi6f5D1g6g

> (8) Has an IPR disclosure been filed that references this document?
> If so, summarize any WG discussion and conclusion regarding the IPR

There were no IPR concerns raised during WG acceptance of the document, nor
during the period of its development.

Very solid.  The document (in the context of the full set of DetNet Data Plane
drafts) is mature and has been discussed sufficiently among the broad DetNet WG
audience.

No.

IDNits passes without errors.

Yes

No.

N/A.

No, N/A.

No, N/A.

N/A, no IANA requests.

None.

The only automated review was idnits.
