1. A method comprising:

  • intercepting, with an intermediate device, a packet flow associated with a communication session between a client device and a server;

    splitting, with the intermediate device, the intercepted packet flow of the communication session into a plurality of application-layer data channels, wherein each application-layer data channel represents an independent stream of application-layer data within the communication session;

    assembling separate application data for each of the application-layer data channels of the communication session;

    performing Quality of Service (QoS) processing on the assembled application data of the application-layer data channels within the intermediate device;

    combining, with the intermediate device, the plurality of QoS-processed application-layer data channels into a combined packet flow; and

    outputting the combined packet flow from the intermediate device onto the communication session between the client device and the server.
