    Abstract: Modern day user applications leverages new communication technologies such as WebRTC, WebEx, and Jabber allow devices to connect and exchange media content including audio streams, video streams, and data stream/channels. The present disclosure describes mechanisms for a Port Control Protocol (PCP) server to provide feedback to PCP clients to enforce certain policies on the transport of such media content for a network. A policy may include a traffic handling policy for enforcing differentiated quality of service characteristics for different types of media streams. Another policy may include a security policy ensuring a data files being transmitted over a data channel from one endpoint travels to a security application via a relay element before the packets reaches another endpoint. The mechanisms are transparent to the endpoints, and advantageously preserve the user experience for these user applications.

    Abstract: Embodiments include detecting an increase in delay of a flow assigned to a first queue of a network device, where the increase is sufficient to cause the flow rate of the flow to decrease if the flow is delay-sensitive. Embodiments further include determining whether an amount of bandwidth consumed by the flow decreases sufficiently after the increase is detected, and assigning the flow to a second queue based, at least in part, on determining the amount of bandwidth consumed by the flow does not decrease sufficiently. Specific embodiments include evaluating a series of two or more bandwidth measurements of the flow according to a bandwidth reduction measure to determine whether the amount of bandwidth consumed by the flow decreases by sufficiently. More specific embodiments include the first queue being configured to receive delay-sensitive flows and the second queue being configured to receive delay-insensitive nice flows.

    Abstract: An example method for facilitating on-demand bandwidth provisioning in a network environment is provided and includes receiving a request from a client at a first network for accommodating flow characteristics at a second network that is associated with executing an application at the first network, determining that the request cannot be fulfilled with available network resources allocated to the client by the second network, advising the client of additional cost for accommodating the flow characteristics, and authorizing additional network resources in the second network to accommodate the flow characteristics after receiving notification from the client of payment of the additional cost.

    Abstract: An example method for access network capacity monitoring and planning based on flow characteristics in a network environment is provided and includes receiving, at a server in a first network, a request from a client at a second network for accommodating flow characteristics for a flow through the first network between the client and a remote destination, accommodating the flow characteristics if the request can be fulfilled with available network resources allocated to the client by the first network, measuring the flow at the first network between the client and the remote destination, exporting flow details including flow measurements and the requested flow characteristics to a flow collector, and denying the request if the flow collector determines that the flow measurements do not match the requested flow characteristics. In some embodiments, the flow measurements include fine-grain flow measurements, wherein the method further comprises receiving a request for the fine-grain flow measurements.
