  • VPN services, providing highest revenue for service providers;
  • customer, having different classes of service - from which to choose;
  • network perspective, traffic arriving from customer - no class of service assigned to it;
  • service implemented using VPLS - as a hub-and-spoke VLAN, and network customer facing interfaces, all Ethernet;
  • classification and trust borders - classification process working on core-facing interfaces;
  • Rewrite rules, ensuring all MPLS traffic - leaving a network router, being either a PE or a P router
