Abstract: 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.

Abstract: 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.

Abstract: 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.
