Title : p2mp pw protection for mpls-tp network

According to one protection Requirement in RFC 5654, Requirement 63
:It MUST be possible to provide protection for the MPLS-TP data plane
without any IP forwarding capability in the MPLS-TP data plane. and
it requires mpls-tp date plane should be independent of its control
plane. so it is necessary for the 1:1 protection of p2mp pw to have a
return path to coordinate the switch state between root node and each
leaf node. for the above problem statement, the document provides a
solution to protect p2mp pw by using one leaf node as protector for
another leaf node. so it may avoid setting up a return path for each
leaf node.
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.
