Abstract:
1. An edge device for interfacing a Multi-Protocol Label Switching (MPLS) network to MAC-in-MAC (MiM) network, comprising: an input port operable to receive a MiM-encapsulated client frame, the MiM encapsulated client frame including a client payload field containing the client frame, a destination MAC address field, a source MAC address field, a B-Tag field, and an I-Tag field; a processor operable to determine a Virtual Private LAN Service (VPLS) service instance on the MPLS network based on the B-Tag field of the MiM-encapsulated client frame, the B-Tag field of the MiM encapsulated client frame being used to identify a MiM tunnel on the MiM network; and an encapsulator operable to encapsulate the MiM-encapsulated client frame with VPLS encapsulation fields corresponding to the VPLS service instance to provide a VPLS-encapsulated frame for transportation on the MPLS network.
