Proposed Standard.

This document defines behaviors requried to interoperability of
different implementations supporting TSN networks interconnected
over a DetNet MPLS Network.

This document describes specifies the data-plane aspects of how IEEE
802.1 TSN networks are interconnected over a DetNet MPLS Network.

Nothing notable.

While there seems to be interest in this speficiations from multiple
vendors, there are no publicly known implementations of this
specification.  There are no specific reviews worth noting.

The Shepherd reviewed this document as it progressed through the WG as
well as part of Last Call.  All significant comments have been resolved.

No

No.

No concerns.  The document basically says use other standards in a
specific way to ensure interoperability.  There's slightly more left for
further documents than I would have hoped, but the approach of defining
data-plane first is reasonable.

Yes, see

No IPR has been disclosed.

I think the document has good support from the narrow set of WG
participants interested in this problem space (TSN over MPLS).

No

Idnits shows unused references that should be removed in the next revision.

N/A. YANG support will be done speperatley based on other work in the WG.

Yes.

No.

No.

No, N/A.

No requests are made in the document.

None.

N/A

There are no yang modules.
