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 translation: 提供了一种用于促进网络环境中的按需带宽供应的示例性方法，并且包括从第一网络的客户端接收请求，以便在与在第一网络处执行应用相关联的第二网络处容纳流特性， 该请求无法通过第二网络分配给客户端的可用网络资源来满足，向客户端通知用于适应流量特性的额外成本，以及授权第二网络中的附加网络资源以在从客户端接收到通知之后适应流量特性 支付额外费用。

Abstract: In one embodiment, a method comprises receiving a stream of transport packets encapsulating media packets, and generating a reference to the point-of-interest media packet relative to the location of the point-of-interest within the transport packet stream. The reference is generated for each media packet that is identified as a point-of-interest.

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.
