Claim Text:
1. A method, comprising: receiving a Multiprotocol Label Switched (MPLS) packet; determining a service type based on a label of the MPLS packet, with the label associated with a particular forwarding equivalence class (FEC), and with said determining the service type including performing a lookup operation, based on the label, in a label forwarding information base (LFIB) in a packet switching device resulting in a lookup result including the identification of the service type and forwarding information, with the service type corresponding to a service offering of a provider operating the packet switching device; extracting a Traffic Class (TC) value from a TC field of the MPLS packet; determining a Quality of Service (QoS) classification value from the service type and the TC value; QoS processing, by the packet switching device, the MPLS packet based on said determined QoS classification value, including QoS processing according to a QoS action identified by the lookup operation in a QoS table based on the QoS classification value; and forwarding the MPLS packet, or a packet derived therefrom, from the packet switching device according to said forwarding information.
