(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)?
Why is this the proper type of RFC? Is this type of RFC indicated
in the title page header?
The MPLS working group request that:
MPLS Generic Associated Channel (G-ACh) Advertisement Protocol
is published as an RFC on the standards track.
This is a standard track document because it is a protocol
specification and also request alloction from IANA registries that
requires a standard track RFC.
(2) The IESG approval announcement includes a Document Announcement
Write-Up. Please provide such a Document Announcement Write-Up.
Recent examples can be found in the "Action" announcements for
approved documents. The approval announcement contains the
The MPLS Generic Associated Channel (G-ACh) provides a data
channel associated with each Label Switched Path (LSP),
pseudowire, or section (link) that a variety of protocols may
use to exchange infomation.
These protocols are commonly used to provide Operations,
Administration, and Maintenance (OAM) mechanisms associated with
the primary data channel. An in-Band Data Communication
Network for Network manaement has also been specified over the
This document specifies simple procedures by which an endpoint of
an LSP, pseudowire, or section may inform other endpoints of its
capabilities and configuration parameters, or other
application-specific information. This information may then be
used by the receiver to validate or adjust its local configuration,
and by the network operator for diagnostic purposes.
Working Group Summary:
Was there anything in WG process that is worth noting? For
example, was there controversy about particular points or were
there decisions where the consensus was particularly rough?
There is good support in the working group for this draft. There
were no significant controversies in progression of the document.
Last call comments were constructive technical comments and the
document has been updated accordingly. .
Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to implement
the specification? Are there any reviewers that merit special
mention as having done a thorough review, e.g., one that resulted
in important changes or a conclusion that the document had no
substantive issues? If there was a MIB Doctor, Media Type or
other expert review, what was its course (briefly)? In the case
of a Media Type review, on what date was the request posted?
For this document we seem to have an chicken and egg problem.
We know of intended implementations, it seems that since the
implementation delta is rather small the implementers in this case
has decided to wait for the allocation of the ACh code point
Who is the Document Shepherd?
Loa Andersson is the document shepherd.
Who is the Responsible Area Director?
Adrian Farrel is the responsible AD.

Shepherd has with this document that the Responsible Area
Director and/or the IESG should be aware of? For example,

There are good support for this document!
(10) Has anyone threatened an appeal or otherwise indicated
extreme discontent? If so, please summarise the areas of
conflict in separate email messages to the Responsible Area
Director. (It should be in a separate email because this
questionnaire is publicly available.)
No such threats!
(11) Identify any ID nits the Document Shepherd has found in
this document. (See http://www.ietf.org/tools/idnits/ and the
Internet-Drafts Checklist). Boilerplate checks are not enough;
this check needs to be thorough.
This document passes the ID-nits tool clean.
(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type
No such formal review requirements!
(13) Have all references within this document been identified as
either normative or informative?
(14) Are there normative references to documents that are not
ready for advancement or are otherwise in an unclear state? If
such normative references exist, what is the plan for their
All normative references are RFCs.
(15) Are there downward normative references references
(see RFC 3967)? If so, list these downward references to support
the Area Director in the Last Call procedure.
No downward references.
(16) Will publication of this document change the status of any
existing RFCs? Are those RFCs listed on the title page header,
listed in the abstract, and discussed in the introduction? If
the RFCs are not listed in the Abstract and Introduction, explain

of this document to the other RFCs is discussed. If this
