# Éric Vyncke, INT AD, comments for draft-ietf-detnet-mpls-oam-14

Thank you for the work put into this document. As my knowledge of MPLS is
rather low, please bear with me. I also found this document not so easy to read
without the context (but this is OK).

Please find below some non-blocking COMMENT points (but replies would be
appreciated even if only for my own education), and some nits.

Special thanks to János Farkas for the shepherd's detailed write-up including
the WG consensus *and* the justification of the intended status.

I hope that this review helps to improve the document,

Regards,

-éric

# COMMENTS (non-blocking)

## Section 3.1

I find weird to only have 4 bits for session IDs and a 5-bit flags field that
has no flag defined yet. I.e., I fear that more than 16 OAM sessions may be
useful.

Is the Node ID a well-known DetNet concept ?

## Section 3.2

Does this section mean that for transit DetNet node, the processing of an OAM
packet is identical (to the bit level) as a normal data plane DetNet packet?
This may be worth mentioning.

## Section 4.1

Should there be an informative reference to IEEE TSN?

## Section 4.2

Suggestion: give more explanations on the interworking with DetNet IP (in the
same level of interworking with TSN in section 4.1).

## Section 6

This document specifies neither LSP ping nor BFD (they are cited as examples),
so, is there a reason to have the last sentence in the security section about
them?

# NITS (non-blocking / cosmetic)

## DetNet or Detnet

The document uses both `DetNet` and `Detnet`, suggest to use only one.
