     Requirements and Framework for Point-to-Multipoint Pseudowires
                             over MPLS PSNs
              draft-ietf-pwe3-p2mp-pw-requirements-07.txt

Abstract

   This document presents a set of requirements and a framework for
   providing a Point-to-Multipoint Pseudowire (PW) over MPLS PSNs.  The
   requirements identified in this document are related to architecture,
   signaling and maintenance aspects of Point-to-Multipoint PW
   operation.  They are proposed as guidelines for the standardization
   of such mechanisms.  Among other potential applications, Point-to-
   Multipoint PWs can be used to optimize the support of multicast layer
   2 services (Virtual Private LAN Service and Virtual Private Multicast
   Service) as defined in the Layer 2 Virtual Private Network Working
   Group.
