Dear Stephen, Adrian

Thank you both for discussing this, please see inline for additional

Ramon> As Adrian has surely pointed you out,  the draft is defining the 
fwk and req for the application of the GMPLS arch and protocols to a new 
switching capability / layer. Indeed, although the  technology/language 
etc., is cumbersome, it will result in relatively minor protocol 
extensions to existing protocols and not much different to what has 
already been done in the past with optical networks with fixed grid, 
OTN, SDH, etc.

We could extend the draft abstract for this, with something in the lines of:

OLD

This document defines a framework and the associated control plane
  requirements for the GMPLS-based control of flexi-grid DWDM networks.

NEW

Given the specific characteristics of flexi-grid optical networks and their
associated technology,  this document defines a framework and the
associated control plane requirements for the application of the existing
GMPLS architecture and control plane protocols to the control of flexi-grid
DWDM networks.  The actual extensions to the GMPLS protocols will be
defined in companion documents.

Thoughts?

thanks
Ramon
