This is an informational document that claims to not state any new requirements or recommendations. I am not following the DetNet work and I only have a coarse understanding of MPLS. As such, I am not able to comment on technical details. There are quite a few sentences that use lowercase 'must' referring to [IEEE8021CB] and [IEEEP8021CBdb]. These references are informational, it seems that [1] suggests that more references should be moved to the normative references section. Since the document claims to not define requirements, I am wondering whether all the "must" statements can be found in other documents. For example: A TSN-aware MPLS (DetNet) node implementations must support the Sequencing function and the Sequence encode/decode function as defined in Clause 7.4 and 7.6 of IEEE 802.1CB [IEEE8021CB] if FRER is used inside the TSN sub-network. In which document do I find this must requirement? I think there should be references to those documents and the specific sections so that it is clear where these "must"s are originating from. (Or the initial promise that this document states not requirements is not quite correct.) [1] https://www.ietf.org/about/groups/iesg/statements/normative-informative-references/ Editorial nits: s/flows with a low/flows with low/ s/provides congestion/provide congestion/ There are some grammar issues throughout the document, I guess the RFC editor will deal with them.
