I also agree with Huub.
As a consensus reached in Beijing meeting, mechanism using the tools defined
for MPLS is a default tool set and another using the tools defined in
G.8013/Y.1731
is an optional one.
That is a an interesting and helpful statement. Obviously, most IETF
participants were not present at this meeting: is there a possibility that this
message could be communicated to the IETF in a more official way?
On October 6 a liaison was sent to the IETF, and the mpls(_at_)ietf(_dot_)org
list with the subject: "New Liaison Statement, "LS332 - Consent of
Recommendation ITU-T G.8113.2/Y.1372.2 -> MPLS"
The liaison informs the IETF that on September 16 recommendation
G.8113.2 was consented in a WP3 plenary meeting.
In both the Beijing Q10 expert meeting where the consent was proposed
and the WP3 plenary meeting where the consent took place, there were
no objections.
G.8113.2 is attached to the liaison and you can read in it:
Scope of G.8113.2:
==================
This Recommendation specifies the default mechanisms for user-plane
OAM (Operations, Administration and Maintenance) in MPLS-TP networks
to meet the MPLS-TP OAM requirements defined in [IETF RFC 5860]. It
also specifies the MPLS-TP OAM packet formats, syntax and semantics
of MPLS-TP OAM packet fields. An optional set of OAM tools based on
G.8013/Y.1731 is described in G.8113.1/Y.1372.1. Annex B of G.8110.1
provides reference scenarios for the interconnection of domains that
use the OAM mechanisms defined in this Recommendation and domains that
normally use the OAM mechanisms defined in G.8113.1/Y.1372.1.
In the Beijing ITU-T expert meeting it was also agreed to change the
scope of G.8113.1 to align it with the scope of G.8113.2.
Scope of G.8113.1:
==================
This Recommendation specifies an optional set of mechanisms for
data-plane OAM (Operations, Administration and Maintenance) in
MPLS-TP networks to meet the MPLS-TP OAM requirements defined in
[IETF RFC 5860]. It also specifies the MPLS-TP OAM packet formats,
syntax and semantics of MPLS-TP OAM packet fields. The default set
of OAM tools is described in [ITU-T G.8113.2]. The MPLS-TP OAM
mechanisms described in this Recommendation are intended to be used in a
Transport Network application described in Annex A of [ITU-T G.8110.1].
Annex B of [ITU-T G.8110.1] provides reference scenarios for the
interconnection of domains using the OAM mechanisms defined in this
Recommendation and domains using the OAM mechanisms defined in [ITU-T
G.8113.2].
=====
So with this liaison LS332 the IETF was already officially informed
about the consent and the fact that there is a default OAM toolset
and an optional toolset.
Regards, Huub.
