Relative priority based QoS interaction between video applications and differentiated service networks

In this research, we investigate quality of service (QoS) interaction provisioning between video applications and components of the DiffServ network. QoS interaction is performed through the mapping of video packets based on the relative quality index (RQI), which represents the relative preference in terms of loss and delay, onto the adaptive packet forwarding mechanism in a DiffServ network. To verify the efficiency of the proposed strategy, the end-to-end performance is evaluated through error resilient packet video transmission over a simulated DiffServ network. Results show that the proposed QoS interaction framework results in an enhanced end-to-end video quality at the same cost constraint.
