* in my earlier comments, I've noted that the informational RFC 8596
appears not posing any requirements for enhancements in the MPLS data plane. If
I am missing something, please let me know.
Hi Greg,
The RFC is mentioned because it shows that SFC NSH has been considered to be
supported in MPLS as well, so it's a legitimate use case like the others in the
draft. When we need to support multiple such use cases at the same time, we
need a generic mechanism to support them, so the use-case draft serves as a
motivation for our work in the ODT.
Hopefully this answers your question. Thanks,
Haoyu

Hi Tarek,
thank you for your thoughtful consideration of my comments. I've reviewed the
diff and got several follow-up notes:
* the new text in the Introduction section explains the ISD as being
encoded as labels:
within the label stack, e.g., encoded as labels, referred to as In
Stack Data (ISD), and
I think s/as labels/into label stack elements/ makes the text a bit more
accurate. What do you think?
* in my earlier comments, I've noted that the informational RFC 8596
appears not posing any requirements for enhancements in the MPLS data plane. If
I am missing something, please let me know.
* I might have missed it earlier. The TSN is the term used for a very
specific technology developed at IEEE to support, for example, URLLC services.
The DetNet WG defines the methodology in support of these services using IETF
technologies - MPLS and IP. I think it would be appropriate if an IETF document
refers to Deterministic Networking, not TSN. What is your opinion?
Regards,
Greg

Dear Authors,
thank you for your work putting this document together. It helps to analyze
essential use cases in the scope of the work at the Open DT. Attached, please
find a copy of the draft with my notes and some editorial suggestions. I hope
you'll find some of them helpful.
I am looking forward to your feedback and questions.
Regards,
Greg
