    abstract =  {This document proposes a solution framework for supporting Metro Ethernet Forum (MEF) Ethernet Tree (E-Tree) services 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.},
