Allocation of a Generic Associated Channel Type for ITU-T MPLS Transport Profile Operation, Maintenance, and Administration (MPLS-TP OAM)
draft-betts-itu-oam-ach-code-point-04
Technical Summary
This document assigns a Generic Associated Channel (G-ACh) Type for
carrying ITU-T MPLS Transport Profile Operations, Administration, and
Management (MPLS-TP OAM) messages in the MPLS Generic Associated
Channel.
This document does not contain technical details of OAM for MPLS-TP
networks. Those details are found in ITU-T determined Recommendation
G.8113.1 that is a normative reference.
Working Group Summary
This document is an individual submission via AD sponsorship aiming to
gain IETF consensus. It is not the product of a working group.
IETF last call was notified to the MPLS and PWE3 working groups.
This document does not make any comment on the judgement of the
working groups in their technical decisions about which MPLS-TP OAM
to standardise, but does observe that the MPLS WG selected a different
OAM mechanism and that the IETF community considers the development
of two sets of MPLS-TP OAM to be a bad idea.
IETF last call saw an active debate, and the document has been updated
to address the comments raised.
Document Quality
This document does not contain protocol details.
Reports have been received suggesting implementation of G.8113.1 by four
vendors with successful interoperability testing, and suggesting that more
than 350,000 nodes have been deployed "that implement or will be
upgraded to implement" the function described in G.8113.1.
The publication of this document will be held in the normal way until the
publication of the normative reference has been achieved. It is
understood that this will require approval of G.8113.1 by the ITU-T.

The RFC Editor should note that there is a normative reference to an
unpublished ITU-T Recommendation, [G.8113.1]. The RFC Editor is
requested to proceed as far as possible through the publication
process for this RFC (including author review of the edited text) so
that publication of the RFC can follow rapidly upon notification from
the ITU-T should they decide to approve and publish their
Reccomendation.
Note that this will require coordination with the IANA as noted in the
IANA Note below.

IESG Note
The IESG notes that the IETF has developed a set of OAM
tools for MPLS-TP that have been published as Standards
Track RFCs. A list of the relevant RFCs can be found in
RFC xxxx. The approval of this document and the
assignment of an ACh Type does not constitute
endorsement by the IETF of the alternate MPLS-TP OAM
documented in G.8113.1. The IESG recommends instead
that the RFCs noted above should be implemented.
[RFC Editor - please replace xxxx with the RFC number
assigned to draft-ietf-mpls-tp-oam-analysis.]

IANA Note
IANA allocations should only be made against stable references.
IANA is requested to make the allocation requested in this
publication only once the ITU-T informs the IETF that G.8113.1
has passed all formal approvals and has been forwarded to their
secretariat for final publication.
