The IESG has received a request from the Pseudowire And LDP-enabled
Services WG (pals) to consider the following document:
- 'Dual-Homing Coordination for MPLS Transport Profile (MPLS-TP)
   Pseudowires Protection'
  <draft-ietf-pals-mpls-tp-dual-homing-coordination-05.txt> as Proposed

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the mailing lists by 2017-02-13. Exceptionally, comments may be
sent to instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.


   In some scenarios, MPLS Transport Profile (MPLS-TP) Pseudowires (PWs)
   (RFC 5921) may be statically configured (management plane based),
   when a dynamic control plane is not available.  A fast protection
   mechanism for MPLS-TP PWs is needed to protect against the failure of
   an Attachment Circuit (AC), the failure of a Provider Edge (PE), or a
   failure in the Packet Switched Network (PSN).  The framework and
   typical scenarios of dual-homing PW local protection are described in
   [draft-ietf-pals-mpls-tp-dual-homing-protection].  This document
   proposes a dual-homing coordination mechanism for MPLS-TP PWs, which
   is used for state exchange and switchover coordination between the
   dual-homing PEs for dual-homing PW local protection.
