1. A method of selecting a network path for transmitting data across a network, the method comprising:

  • receiving at a first network appliance, a first packet of a first flow to be transmitted across a network;

    extracting information from the first packet;

    using an application inference engine influenced by a learning algorithm to infer at least one of an application name and one or more application tags for the first flow based on the extracted information;

    selecting by the first network appliance, a network path based on the inferred at least one of application name and one or more application tags; and

    transmitting the first flow by the first network appliance via the selected network path to a destination.
