     A Framework for Point-to-Multipoint MPLS in Transport Networks

Abstract

   The Multiprotocol Label Switching Transport Profile (MPLS-TP) is the
   common set of MPLS protocol functions defined to enable the
   construction and operation of packet transport networks.  The MPLS-TP
   supports both point-to-point and point-to-multipoint transport paths.
   This document defines the elements and functions of the MPLS-TP
   architecture that are applicable specifically to supporting point-to-
   multipoint transport paths.

RFC 7167          MPLS Transport Profile P2MP Framework       April 2014

1.  Introduction

   The Multiprotocol Label Switching Transport Profile (MPLS-TP) is the
   common set of MPLS protocol functions defined to meet the
   requirements specified in [RFC5654].  The MPLS-TP Framework [RFC5921]
   provides an overall introduction to the MPLS-TP and defines the
   general architecture of the Transport Profile, as well as the aspects
   specific to point-to-point transport paths.  The purpose of this
   document is to define the elements and functions of the MPLS-TP
   architecture applicable specifically to supporting point-to-
   multipoint transport paths.
