A Framework for Ethernet Tree (E-Tree) Service over a Multiprotocol
Label Switching (MPLS) Network
draft-ietf-l2vpn-etree-frwk-05.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.
