13. A method as recited in claim 1 , wherein the PBT frame comprises a Provider Backbone Bridge Traffic Engineering (PBB-TE) frame.

14. A method as recited in claim 1 , where in obtaining the PBT service lookup table to map the PBT frame to the service comprises to map based at least in part on a first match of the service to one or more of the plurality of location specific identifiers in the PBT frame.

15. A method as recited in claim 1 , where in obtaining the PBT service lookup table to map the PBT frame to the service comprises to map based at least in part on a longest match of the service to one or more of the plurality of location specific identifiers in the PBT frame.

16. A system for transferring data in a network, comprising:

a processor; and

a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to:

receive a Provider Backbone Transport (PBT) frame, wherein the PBT frame is received at a provider edge device configured to transfer data between a Provider Backbone Bridge Network (PBBN) and a Multiprotocol Label Switching (MPLS) network;

identify, at the provider edge device, a plurality of location specific identifiers in the PBT frame, the plurality of location specific identifiers including: a service instance identifier (I-SID), a customer virtual local area network identifier (C-VID), a service virtual local area network ID (S-VID), and a pseudowire identifier (PW ID);

obtain, at the provider edge device, a PBT service lookup table to map the PBT frame to a service based at least in part on the plurality of location specific identifiers, wherein the PBT service lookup table has been provisioned in response to an indication of a service change for a customer associated with the PBT frame;

format, at the provider edge device, the PBT frame according to the service to obtain a service frame; and

transfer, by the provider edge device, the service frame to a network associated with the service.

17. A computer program product for transferring data in a network, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a Provider Backbone Transport (PBT) frame, wherein the PBT frame is received at a provider edge device configured to transfer data between a Provider Backbone Bridge Network (PBBN) and a Multiprotocol Label Switching (MPLS) network;

identifying, at the provider edge device, a plurality of location specific identifiers in the PBT frame, the plurality of location specific identifiers including: a service instance identifier (I-SID), a customer virtual local area network identifier (C-VID), a service virtual local area network ID (S-VID), and a pseudowire identifier (PW ID);

obtaining, at the provider edge device, a PBT service lookup table to map the PBT frame to a service based at least in part on the plurality of location specific identifiers, wherein the PBT service lookup table has been provisioned in response to an indication of a service change for a customer associated with the PBT frame;

formatting, at the provider edge device, the PBT frame according to the service to obtain a service frame; and

transferring, by the provider edge device, the service frame to a network associated with the service.

18. A method of transferring data in a network, comprising:

obtaining, at a provider edge device, a PBT service lookup table to map a received Provider Backbone Transport (PBT) frame to a service based at least in part on a plurality of location specific identifiers in the received PBT frame, the plurality of location specific identifiers including: a service instance identifier (I-SID), a customer virtual local area network identifier (C-VID), a service virtual local area network ID (S-VID), and a pseudowire identifier (PW ID), wherein:
