That's probably a little too far from PPML's charter to be a good topic for
this mailing list... There's quite a bit of existing discussion of the MPLS
OAM difference of opinion over on LightReading in this article:
the associated links that follow the article. The main IETF mailing list
also has some discussion of the topic.
Short version is that the IETF and ITU agreed on an approach to a single
OAM standard for MPLS, and the IETF has been working on it (albeit slower
than expected) and it appears that some of the vendors in the ITU community
continued to ship product based on the ITU version in the meantime. This
ultimately came to a head last month, when the ITU Study Group 15 decided
to adopt the ITU original proposal despite its earlier agreement with the IETF
to work on a single joint standard. Implications could include interoperability
issues for large-multivendor MPLS networks, and general concern about the
strength of commitment behind any other agreements that the ITU might enter
in the future. This is the aspect of the dispute that is disturbing for ARIN, and
requires careful thought when considering offers from the ITU to "work together"
on any Internet number resource activities.
