Optimal QoS mapping for streaming video over Differentiated Services networks

We investigate streaming packet video over relative Differentiated Services (DiffServ) networks which can provide a number of aggregated traffic classes, ordered in a way such that class q+l is better or at least no worse than class q in terms of packet loss. We propose an algorithm for optimal quality of service (QoS) mapping from the video packets to a set of available DiffServ classes. The performance of our algorithm is evaluated through experimental tests and compares favorably to previous works.
