Please find below some non-blocking COMMENT points (but replies would be appreciated even if only for my own education), and one nit. Special thanks to János Farkas for the shepherd's detailed write-up including the WG consensus and the justification of the intended status. Other thanks to Roman Danyliw as the acting AD ;-) I hope that this review helps to improve the document, Regards, -éric # COMMENTS (non-blocking) ## Section 1 Is the 1st paragraph defining what is OAM a little too light ? Operations cover more than performance monitoring. But, this is not critical for this I-D. ## Section 2.1 Should there be a reference for diff serv and ICMPv[46]? Isn't it a little weird to use in an IP-only document the sentence `MPLS networks providing LSP connectivity between DetNet nodes are an example of the underlay layer` ? ## Section 3 I will let my fellow OPS ADs to chime in, but `OAM protocols and mechanisms act within the data plane of the particular networking layer` is of course applicable for the in-path monitoring part of OAM, but probably not for the control part of OAM, e.g., netconf can be in a separate plane. What about the use of IPv6 flow label ? Would it help for the IPv6 flows ? ## Section 3.1 While I am far from being a "flow hash" expert, is it really possible for compute UDP ports having the same hash value ? Especially when most vendors do not make their flow hash algorithms public ? To be honest, the intent of sections 3.1 to 3.4 are unclear to me, hence my above question. ## Section 7 I was really about to raise a DISCUSS for this, but it is too trivial to fix: please either remove this section or add some contents. # NITS (non-blocking / cosmetic) ## Oxford comma ? Should there be an Oxford comma in `Administration and Maintenance`? Notably in the title and other places.
