1. A method, comprising:
receiving, by an agent executed by a device, a packet generated by an application executed by the device that includes a flow profile identifier associated with a particular flow profile, wherein the particular flow profile is selected by the application from among a plurality of flow profiles for the application and communicates a particular treatment of the packet in a computer network, wherein each of the plurality of flow profiles is unique to the application and indicates a priority level associated with traffic of different flows associated with the application;
determining, by the agent, one or more adjustments to the packet based in part by matching the flow profile identifier of the packet to the particular flow profile for the application;
forming, by the agent, an adjusted packet by applying the one or more adjustments to the packet; and
sending, by the agent, the adjusted packet to an external destination via a network.
