  • Publication number: 20080089324
    Abstract: In some embodiments, a method for replacing an existing Differentiated Services Code point (DSCP) value with a new DSCP value, or augmenting an existing DSCP value with a new DSCP value is described. In an example embodiment, a new DSCP value is generated, added to the value field of a protocol session and transmitted to another device. The protocol session may be SIP, SDP, RTSP or some other suitable protocol. In an example embodiment, a system is described wherein a first device is operatively coupled to a second device in a peer to peer configuration, wherein communications between the first and second device is controlled by a third device.
