1. A method of communication for a plurality of software applications over a wide-area packet-switched network, wherein the packet-switched network communicates via a best-efforts protocol operating on a first layer of the packet-switched network, and a label switching protocol operating on a second layer of the packet-switched network, the method comprising:

  • at one or more nodes in the wide-area packet-switched network, classifying packets traversing through the one or more nodes into a plurality of microflows, the classifying packets further including detecting identifying signatures for the packets, mapping the signatures to the plurality of microflows;

    mapping in real-time the plurality of microflows to a plurality of label-switched paths, the label-switch paths generated by the label switching protocol, mapping the plurality of microflows further including determining a current status of each of the plurality of label-switched paths, for each micro-flow from the plurality of micro-flows, determining a rule applicable to the micro-flow, wherein the rule specifies one or more network characteristics for the microflow, and comparing the rule applicable to the micro-flow to the current status of each of the plurality of label-switched paths to select a label-switched path from the plurality of label-switched paths on which to forward the microflow.
