Abstract 
    
   This document proposes a simple extension to LDP-VPLS to improve 
   bandwidth efficiency for Ethernet broadcast/multicast traffic 
   within a carrier's network. It makes use of unidirectional 
   point-to-multipoint PseudoWires to minimise payload frame duplication
   on physical links.

1. Introduction 
   
   This document proposes a simple extension to LDP-VPLS [RFC4762] to 
   improve bandwidth efficiency for Ethernet broadcast/multicast traffic
   within a carrier's network. This bandwidth improvement is achieved by
   adding to the existing full-mesh of bidirectional point-to-point
