Abstract: A computer-implemented method includes sending a first request message to a first server associated with a first access network indicative of a request for an indication of whether the first server is configured to support prioritization of tunneled traffic, receiving a first response message from the first server indicative of whether the first server is configured to support prioritization of tunneled traffic, establishing one or more first tunnels with a security service when the first response message is indicative that the first server is configured to support prioritization of tunneled traffic, sending first flow characteristics and a first tunnel identifier to the first server; and receiving the first flow characteristics for each first tunnel from the first server at a first network controller. 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.

Abstract: An example method for reducing real time media traffic in a network environment is provided and includes examining a plurality of first requests in a first protocol to identify participants in a media session; examining a plurality of second requests in a second protocol to determine media characteristics associated with the participants; and grouping the participants into different groups based, at least in part, on the media characteristics, wherein at least some of the participants associated with substantially identical media characteristics are grouped together.

Abstract: In one implementation, a conference bridge connects endpoints in a media conference. The various endpoints may have a wide range of video capabilities and audio capabilities. The video conference bridge learns the video capabilities of the endpoints and formulates a media plan based on these capabilities. The media plan instructs the endpoints on the types of media streams to produce. The video conference bridge may shape a media stream received from one of the endpoints by removing one or more layers. Accordingly, each endpoint decodes only the media streams that can be encoded by another endpoint and receives the best possible media stream from each endpoint.

Abstract: A method and apparatus for unicast and multicast media processing is provided. The method may comprise receiving multicast packets communicating a plurality of media streams from a plurality of communication endpoints. Each communication endpoint may have an associated individual media stream. The method inspects the multicast packets to identify each individual media stream with which the packet is associated and individually processes each individual media stream. At least one individual media stream is unicast from its associated buffer to a unicast communication endpoint of the plurality of communication endpoints. In an example embodiment, the method may identify media capabilities of the unicast communication endpoint. The plurality of media streams may form part of a virtual talk group (VTG) in an audio conference.

Abstract: Methods and devices for querying any-service-any-port policy systems. A method for a network device to route calls using policy considerations receives a call request associated with a call and queries a policy system to determine if the network can accept the call. A message is then generated that includes a response to the request.
