Title : p2mp pw protection for mpls-tp network Author(s) : ZTE Corporation Filename : draft-liu-pwe3-mpls-tp-p2mp-pw-protection-00.txt Pages : 10 Date : 2011-12-29 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.
