Document: draft-ietf-opsawg-mpls-tp-oam-def-09 Reviewer: Scott Brim Review Date: 12 April 2011 IETF LC End Date: 20 April 2011 IESG Telechat date: (if known) Summary: Not ready for publication as a BCP Major issues: The goal is good, but imho the draft is poorly organized, with the result that it does not achieve its purpose well. - Give Section 2 a more informative title -- the content appears to be a section on how O, A and M are used in other SDOs, by way of introduction, but the title does not say so. - In Sections 2.2.1 and 2.2.2, no IETF recommendations or disambiguation are included. That's find. However, Section 2.2.3 makes recommendations. The decision to use M to mean "maintenance", and what "maintenance" actually means should be moved to Section 3 (titled "Recommendations" in fact). Having a recommendation mixed in with a survey of other usage is confusing to the reader. - There should be another section after Section 4, a follow-up to Section 2, a discussion section to show how the IETF usage differs from that in other SDOs. Otherwise, what's the point of Section 2? It sets the stage by showing the problem ... but then all that scenery is abandoned. - One of the justifications for the recommendation is that OAM including maintenance is "horizontal" (on-path) while management is "vertical" (element - element mgr). That's a good distinction. However, the "administration" as defined in Section 3 is "vertical". Perhaps based on the draft's own justification, OAM should _not_ include "administration" and just be defined as "operations and maintanence"! ... but we don't want that outcome, so I suggest reworking the justification to avoid logical inconsistency.
