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: According to one configuration, a wireless communication system includes one or more wireless communication devices and gateway hardware. The gateway hardware can be configured to notify the one or more wireless communication devices of a change associated with frequency hopping settings (such as switchover from first frequency hopping settings to second frequency hopping settings). Further, the gateway hardware can include a first radio frequency interface and a second radio frequency interface. In accordance with the frequency hopping settings, the gateway hardware: i) fixedly tunes the first radio frequency interface to a first wireless channel; and ii) while the first radio frequency interface is fixedly tuned to the first wireless channel, the gateway hardware dynamically tunes the second radio frequency interface to hop amongst multiple different wireless channels.

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.

The first network controller is configured to apply a quality of service policy within the first access network for each tunnel in accordance with the flow characteristics.
