     A Framework for Point-to-Multipoint MPLS in Transport Networks
                  draft-ietf-mpls-tp-p2mp-framework-05

Abstract

   The Multiprotocol Label Switching Transport Profile 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 applicable specifically to supporting point-to-
   multipoint transport paths.

1.  Introduction

   The Multiprotocol Label Switching Transport Profile 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 those 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.
