1. A network for transporting customer Ethernet frames, the network comprising:

  • an Ethernet access network configured to;

    receive a customer frame on a network port, the customer frame including a customer destination MAC address (C-DA) and a customer source MAC address (C-SA);

    identify a customer service instance based on at least one of the network port and a VLAN associated with the frame; and

    encapsulate the customer frame with a backbone destination MAC address (B-DA), a backbone source MAC address (B-SA), and information identifying the customer service instance associated with the frame, the B-DA being selected based on the customer service instance; and

    a Multi-Protocol Label Switching (MPLS) network coupled to the Ethernet access network, the MPLS network implementing a pseudo-wire service and being configured to;

    further encapsulate the customer frame with a Label Switched Path (LSP) label and a pseudo-wire label, the pseudo-wire label being selected based on the information identifying the customer service instance and the LSP label being selected based on the B-DA; and

    forward the encapsulated frame toward a network node associated with the B-DA based on the LSP label.
