Liaisons referred by this one Communication to ITU-T Q6/15 and Q12/15 from IETF's CCAMP Working Group on Flexible Grids
ITU-T SG15 Q6/15 and Q12/15 would like to thank IETF’s CCAMP WG for its
Liaison Statement on starting work on enhancing GMPLS's support for Wavelength
Switched Optical Network (WSON) equipment to support Flexible Grids.
Q6/15 and Q12/15 would like to inform IETF’s CCAMP WG that revised
Recommendation ITU-T G.694.1 was consented at the Plenary SG15 Meeting in
Geneva, 5-16 December 2011, introducing the concept of a flexible grid.
Furthermore a joint meeting was held between Q6, Q7, Q9, Q11, Q12 and Q14 of
SG15 to discuss potential follow-up work on the flexible grid within these
questions. In order to provide some input to this joint meeting, the Q6/15
Rapporteur and Associate Rapporteur drafted the document, attached as
Attachment 1 to this Liaison Statement, containing some specific
considerations relevant to the introduction of the flexible grid in revised
ITU-T G.694.1.
Furthermore Q6/15 would like to inform IETF’s CCAMP WG that also a revised
version of Recommendation ITU-T G.697 was consented at this SG15 Plenary
Meeting, where some of the parameter encoding was modified to take account of
the introduction of a flexible grid in ITU-T G.694.1.
In order support the work in IETF’s CCAMP WG both consented ITU-T G.694.1 and
ITU-T G.697 are attached.
As SG15 further progresses with the work on this topic, we would be happy to
inform the IETF’s CCAMP WG about the progress made. Q6/15 and Q12/15 are
looking forward to future exchanges of information with IETF’s CCAMP WG.

Attach:	Consented ITU-T G.694.1 (TD502/PLEN Rev.2).
Consented ITU-T G.697 (TD505/PLEN Rev.1).
