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).
