A method is described and in one embodiment includes receiving at a first node in a communications network a Session Traversal Utilities for Network Address Translation ('STUN') message associated with a first flow, wherein the STUN message comprises a flow attribute including corresponding to the first flow; analyzing the flow attribute at the first node; setting policy corresponding to the first flow in the network based on the analyzing, wherein setting the policy includes using the flow attribute of the STUN message to configure a network path for the first flow in the communications network; and forwarding the STUN message to a next network node.

Techniques for informing communications networks of desired packet transport treatment

Dynamic application QoS profile provisioning may be provided. First, an access point may send a profile to a client device. The profile may comprise a plurality of application identifiers and a plurality policies corresponding to the plurality of application identifiers. Each of the plurality of application identifiers may respectively correspond to a plurality of applications. Next, the client device may receive the profile. Then the client device may select, from the received profile, a first policy from the plurality policies in the profile. The first policy may correspond to a first application identifier in the plurality of application identifiers. The first application identifier may correspond to a first application within the plurality of applications. The first application may be on the client device. The first application on the client device may then create a network flow from the client device to the access point based on the selected first policy.

Dynamic application QoS profile provisioning

A method is described and in one embodiment includes receiving at a first node in a communications network a message associated with a first flow, wherein the message comprises a flow treatment attribute including metadata indicative of how the first flow should be treated in the network; analyzing the flow treatment attribute at the first node; setting policy for treatment of the flow in the network based on the analyzing; and forwarding the message to a next network node.

In one embodiment, a first device in a network sends a Session Traversal Utilities for Network Address Translation (STUN) binding request towards an endpoint device of a media session between the first and endpoint devices. The binding request includes one or more network attribute fields. The first device receives a binding response from an intermediate node between the first and endpoint devices in the network, in response to sending the binding request towards the endpoint device. The intermediate node inserted the one or more network attribute fields into the binding response. The received binding response includes one or more metrics for the media session in the one or more network attribute fields. The first device adjusts one or more bitrates of the media session based on the one or more metrics for the media session in the received binding response.
