Liaisons referring to this one Update on MPLS-TP protection work in MPLS and PALS working groups
ITU-T SG15 wishes to inform the IETF mpls WG of an update to the ITU-T Q9/15
work programme to include a second amendment to Recommendation ITU-T
G.8131/Y.1382 Linear protection switching for MPLS transport profile. This
amendment will cover pseudowire protection based on Appendix A of IETF RFC
7771. The amendment is targeted for consent at the September 2016 plenary
meeting of SG15.

ITU-T Q9/15 has also been made aware of the initiation of work on MPLS-TP
Shared-Ring protection (MSRP) mechanism for ring topology in
draft-ietf-mpls-tp-shared-ring-protection-00, and has consequently re-initiated
work on draft Recommendation ITU-T G.8132/Y.1383 Ring protection switching for
MPLS transport profile. As ITU-T Q9/15 intends to reference and be aligned with
corresponding normative RFCs, we would appreciate your assessment of the
anticipated completion date for draft-ietf-mpls-tp-shared-ring-protection as
the target consent date for draft Recommendation ITU-T G.8132/Y.1383 depends on
