assigning, by the system, the first subset of the data packets to a first data stream;

assigning, by the system, the second subset of the data packets to a second data stream,

encapsulating, by the system, a first data packet of the first data stream with a first pseudowire header associated with a first pseudowire, wherein the first pseudowire comprises a first plurality of intermediate nodes; and

identifying, by the system, the flow identification information based on header information associated with at least one of the data packets; and

mapping, by the system, the at least one of the data packets to an application flow based on the header information.

3. The method of claim 1 , further comprising setting, by the system, at least one of a packet label field, a sequence number field, a service differentiation field, a service guarantee field, or a flow control field in at least one of the first pseudowire header or the second pseudowire header.

4. The method of claim 1 , wherein the encapsulating the first data packet yields a first encapsulated data packet, and the encapsulating the second data packet yields a second encapsulated data packet, and the method further comprises:

sending, by the system, the first encapsulated data packet over the first pseudowire via one or more first multi-protocol label switching devices; and

sending, by the system, the second encapsulated data packet over the second pseudowire via one or more second multi-protocol label switching devices.

5. The method of claim 1 , further comprising:
