	Title           : MPLS-TP protection for interconnected rings

   According to the ring protection Requirements in RFC 5654,
   Requirement 93 : When a network is constructed from interconnected
   rings, MPLS-TP MUST support recovery mechanisms that protect user
   data that traverses more than one ring.  This includes the
   possibility of failure of the ring-interconnect nodes and links,so
   this document will describle all kinds of interconnected ring
   Scenarios and several protection solutions for recovery the failure
   of the ring-interconnect nodes and Links. .


   This document is a product of a joint Internet 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.
