Technical Summary

  The Transport Profile for Multiprotocol Label Switching (MPLS-TP) is
  being specified jointly by IETF and ITU-T.  This document addresses
  the functionality described in the MPLS-TP Survivability Framework
  document and defines a protocol that may be used to fulfill the
  function of the Protection State Coordination for linear protection.

  Linear protection provides rapid and simple protection switching.
  In a mesh network, linear protection provides a very suitable
  protection mechanism because it can operate between any pair
  of points within the network.  It can protect against a defect in an
  intermediate node, a span, a transport path segment, or an end-to-end
  transport path.

Working Group Summary 

  This document has been carefully reviewed by the MPLS WG as well as
  by ITU-T SG15.

  A summary of the resolution of the many comments received has been
  posted to the MPLS WG email list.
