Abstract:
   The requirements for MPLS Transport Profile include a requirement
   (R93) that requires that MPLS-TP must support recovery mechanisms for
   a network constructed from interconnected rings that protect user
   data that traverses more than one ring.  In particular, this includes
   protecting against cases of failure at the ring interconnect nodes
   and links.  This document presents different configurations of
   interconnected rings and special mechanisms to address the recovery
   of ring-interconnect nodes and links. .

   This document is a product of a joint Internet Engineering Task
   Force(IETF) / International Telecommunications Union
   Telecommunications Standardization Sector (ITU-T) effort to include
   an MPLS Transport Profile within the IETF MPLS and PWE3 architectures
   to support the capabilities and functionalities of a packet transport
   network as defined by the ITU-T.
