A new revision of the MPLS and GMPLS change process I-D is available. This
process appears to be stable and we are thinking of taking to the IESG quite
soon, so review it now or risk having to live with it.
The changes in this revision are largely to clarify the use of the
Preliminary Investigation phase.

Although this document is not a protocol definition, the key words
"MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document
are to be interpreted as described in RFC 2119 [RFC2119]. This usage
is chosen to make the steps and procedures completely clear.
Section 2.3 final paragraph
It should be noted that the first stage in the change process is an
optional Preliminary Investigation (see Section 4.2.1). This stage is
explicitly included to allow external organizations to discuss
requirements and proposed uses of the (G)MPLS technologies without
the need to first develop Internet-Drafts, and builds on existing
liaison processes where they exist.
o Preliminary Investigation
An optional preliminary phase that may be used to exchange views
on a proposed requirement and usage of the (G)MPLS technologies
without going to the effort of writing an Internet-Draft. This
phase may be particularly useful to SDOs that have already
invested heavily in documenting a problem statement, or may be
used by anyone who wishes to hold discussions on the use of
ADD para 2
Whenever there is reason to believe that a particular problem may be
solved by use of or extensions to the (G)MPLS protocols, a
preliminary investigation phase may be used to discuss the
requirements with the IETF. This may lead to an understanding that
the problem is already solved, is outside the scope of the IETF, or
requires more investigation possibly leading to changes to the
Section 4.2.1 para 2
In fact, although this step is described
as lightweight because no Internet-Draft is required and because the
nature of the step is discursive, it may be the case that this step
involves considerable technical discussions and may, in fact, be an
extensive, substantive exchange of opinions.
Section 4.2.1 para 3
Section 4.2.1 final para
A possible outcome of this preliminary invsetigation is that the
requirements and problem are understood, but agreed to be out of
scope for the IETF. Alternatively it may be that the problem can be
solved with existing protocols.
