Body:
Thank you for your liaison from your Madeira interim meeting on T-MPLS
Ring Protection, and for taking the time to keep us informed.

At the moment, it appears that your work is limited to the MPLS
forwarding plane with control from the Management Plane with
coordination with MPLS OAM. As such, this work falls within the remit
of the IETF's MPLS and PWE3 working groups. You will also be aware that
the IAB has set up a design team to address issues in preparation of
the potential cooperation between IETF and ITU-T on T-MPLS; we trust
that you have appropriately consulted this team in keeping with the
spirit of cooperation between the ITU-T and the IETF.

At such time as work within the ITU-T on T-MPLS ring protection (or
indeed on any aspect of T-MPLS) extends to requirements or solutions
for a control plane, we request that you communicate with us early in
the process so that we may ensure that the industry arrives at a single
and fully compatible solution.

Best regards,
Adrian Farrel and Deborah Brungard
IETF CCAMP Working Group Co-Chairs
