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.
