Sorry for the short-term request (but this document has been placed very recently on the IESG telechat) but it is about 10 pages long. I would appreciate a review from the IoT perspective. Thank you -éric |

I have reviewed draft-ietf-detnet-ip-over-tsn from IoT point of view, as part of IoT directorate document reviews. The document specifies the DetNet IP data plane when operating on a TSN sub-network, and builds on RFC8939 and RFC8565 to do so. The document is well-written and appears to be Ready (with some minor nits). I did not identify any IoT related issues with the document. Nits: - RFC8939 reference does not render as link in section 1, first paragraph, but works in the second paragraph. In section 3 again no link. - Section 1, third paragraph: This sentence is strange: "As described in [RFC8939] no DetNet specific headers are added to support DetNet IP flows, only the forwarding sub-layer functions are supported inside the DetNet domain." - section 2.2. Abbreviations DF and PREOF not used in rest of document. - general, mix of using L2 and Layer-2 - general, there are some long, complex to parse, sentences that could perhaps be split or rephrased into something clearer. E.g. 4.2, third paragraph, "In cases of TSN-unaware IP DetNet nodes the TSN relay nodes within the TSN sub-network must modify the Ethernet encapsulation of the DetNet IP flow (e.g., MAC translation, VLAN-ID setting, Sequence number addition, etc.) to allow proper TSN specific handling inside the sub-network." - general, IEEE specs are referred to as "IEEE 802.1CB [IEEE8021CB]", which makes the many references to clauses long to read. Can't you just say e.g., "Clause 6.6 of [IEEE8021CB]" instead of ""Clause 6.6 of IEEE8021CB [IEEE8021CB]", except for maybe the first reference?
