The conclusion drawn from some initial discussions on specific
routing protocols was to step back for a moment and develop a
so-called mid-level requirements recommendation for a link state
routing protocol which still should be protocol neutral. This
requirements recommendation will then be used for the assessment
of existing link state routing protocols to be applied in ASON.

The ITU-T has invited the IETF GMPLS routing experts to participate, as per Wesam's presentation documented in the IETF-56/CCAMP meeting minutes http://ietf.org/proceedings/03mar/minutes/ccamp.htm.
I fully share your view - the idea was indeed to invite IETF GMPLS
routing experts in order to have a closer and much better cooperation
on routing compared to what happened with signaling.


Furthermore, I would like to add that I have read this document
and it is ready to be a CCAMP WG doc (being aware that some
issues need further discussion or clarification which shouldn't
preclude that this document becomes a WG doc)
