When IPPM started working on IOAM, there was a long discussion on naming – and the conclusion was that “in-band” as not appropriate for OAM information being piggybacked on top of user traffic. This is why the IPPM WG concluded to use “In-situ OAM” – or “IOAM” for short, which is what is used in RFC9197 and all related documents.

Subject: [ippm] IOAM, iOAM, and oOAM abbreviations

Dear All,
Loa and I have discussed these abbreviations to help us find a solution that avoids the confusion we found when we came across them. Firstly, what they stand for:

  *   IOAM - In-situ OAM (RFC 9197<https://datatracker.ietf.org/doc/rfc9197/>)
  *   iOAM - in-band OAM (RAW architecture<https://datatracker.ietf.org/doc/html/draft-ietf-raw-architecture-13>)
  *   oOAM - out-of-band OAM (RAW architecture<https://datatracker.ietf.org/doc/html/draft-ietf-raw-architecture-13>)
We discussed the issue with Pascal and came to slightly different abbreviations for the last two:

  *   inb-OAM
  *   oob-OAM
We also discord these abbreviations with the RFC Editor. Resulting from that, RFC Editor agreed to add IOAM to the RFC Editor Abbreviation List<https://www.rfc-editor.org/materials/abbrev.expansion.txt>. The other two abbreviations cannot be added at this time. If that is needed, we can ask the RFC Editor to add them once the respective RFC is published.
We are seeking your feedback on the following:

  *   Do you see the benefit of introducing two new abbreviations for in-band OAM and out-of-band OAM?
  *   Which set of abbreviations (iOAM/oOAM vs. inb-OAM/oob-OAM) do you prefer for being used in IETF?
  *   Or would you propose another set of abbreviations?
Regards,
Loa and Greg
