This document is requested for publication as an Informational document.
This is appropriate because the document describes the framework for
a network and high-level requirements for control plane extensions.
Although the document contains some RFC 2119 language, this is limited
to very high-level network requirements. The appropriate track for this
document has been extensively discussed on the WG mailing list and with
the Chairs and Responsible AD.
This track is noted in the document header.

> Technical Summary:
To allow efficient allocation of optical spectral bandwidth for high
bit-rate systems, the International Telecommunication Union
Telecommunication Standardization Sector (ITU-T) has extended its
Recommendations G.694.1 and G.872 to include a new dense wavelength
division multiplexing (DWDM) grid by defining a set of nominal
central frequencies, channel spacings and the concept of "frequency
slot". In such an environment, a data plane connection is switched
based on allocated, variable-sized frequency ranges within the
optical spectrum creating what is known as a flexible grid (flexi-
This document defines a framework and the associated control plane
requirements for the GMPLS-based control of flexi-grid DWDM networks.
> Working Group Summary:
This document has been reviewed by the CCAMP working group and received
some comments at IETF meetings and on the mailing list.
There was some early and intense discussion about whether to include
capabilities for data plane features under development in, but not yet
standardised by, the ITU-T. The WG came to consensus that these must
remain out of scope for now.
There were no problems with consensus for this document.
> Document Quality:
The work has had contributions from a large group of people. This
arises from the combination of a number of drafts, and also from great
early interest in the work. Additionally, the work has had external
review from the IDEALIST EU project that is making multiple inter-
operating implementions of a GMPLS control plane for flexi-grid.

The WG chairs chased all authors and contributors for statements that
they had complied with IETF IPR policy. All responded.

No disclosures have been made.

There has been substantial and broad review. There is good consensus
on the document.

No threats or discontent.

idnits warns about normative references to ITU Recommendations as
potential downrefs, but everything is OK.
