Abstract:
   The requirements for MPLS Transport Profile include a requirement
   (R93) that requires 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 scenario of
   interconnected rings and special mechanism to address recovery of the
   failure 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.
