   For the Multiprotocol Label Switching Transport Profile (MPLS-TP)
   linear protection capable of 1+1 and 1:1 protection has already been
   defined.  That linear protection mechanism has not been designed for
   handling multiple, simultaneously occuring failures, i.e. multiple
   failures that affect the working and the protection entity during the
   same time period.  In these situations currently defined protection
   mechanisms would fail.

   This document introduces use cases and requirements for mechanisms
   that are capable of protecting against such failures.  It does not
   specify a multi-failure protection mechanism itself.
