Hi All, I think this is a useful document. However, I have some comments: - When referring to Hybrid OAM, I suggest to specify if it is Type I or Type II, in order to be more aligned with RFC 7799 terminology. I noticed that various examples in the text are simply referred as Hybrid OAM. - I would mention the Active OAM variation described in draft-ietf-ippm-on-path-active-measurements, that is when Hybrid OAM methods are combined with Active OAM tools to perform active on-path measurements. According to the definitions in RFC7799, this is still Hybrid Type I. - Consequently, I propose to revise the definition of In-Data-Packet OAM and specify that it is a subset of Hybrid Type I, where the OAM information is carried in the user traffic stream. In this way, it is clear that, any application to a specially generated stream can be Hybrid Type I but it is not In-Data-Packet OAM. - Finally, I suggest to add another classification for the OAM methods, depending on whether the method can support on-path (hop-by-hop) or only edge-to-edge measurements.

Abstract: As the IETF continues to produce and standardize different Operations, Administration, and Maintenance (OAM) protocols and technologies, various qualifiers and modifiers are prepended to the OAM abbreviation. While, at first glance, the most used appear to be well understood, the same qualifier may be interpreted differently in different contexts. A case in point is the qualifiers "in-band" and "out-of-band" which have their origins in the radio lexicon, and which have been extrapolated into other communication networks. This document recommends not to use these two terms when referring to OAM. This document considers some common qualifiers and modifiers that are prepended, within the context of packet networks, to the OAM abbreviation and lays out guidelines for their use in future IETF work. This document updates [RFC6291] by adding to the guidelines for the use of the term "OAM". It does not modify any other part of [RFC6291].
