   A Framework for Ethernet Tree (E-Tree) Service over a Multiprotocol
                      Label Switching (MPLS) Network
                    draft-ietf-l2vpn-etree-frwk-10.txt

Abstract

   This document describes an Ethernet-Tree (E-Tree) solution framework
   for supporting the Metro Ethernet Forum (MEF) E-Tree service over a
   Multiprotocol Label Switching (MPLS) network. The objective is to
   provide a simple and effective approach to emulate E-Tree services
   in addition to Ethernet LAN (E-LAN) services on an existing MPLS
   network.
