Dynamic quality of service (QoS) mapping control with relative service differentiation network is a futuristic framework to achieve high-quality end-to-end video streaming. The proper QoS mapping in terms of delay and loss between categorized-packet video and proportional differentiated services (DiffServ, DS) network can improve video quality under the same cost constraint. However, network congestion caused by traffic load fluctuation still remains as the main hinderance in providing persistently better service even though the resource provisioning policy of underlying network is well-established. To address this issue, we propose a class-based feedback control to enhance relative service differentiation-aware video streaming. The major idea of our proposal is to employ explicit congestion notification (ECN) mechanism in conjunction with the QoS mapping control at the ingress of a DiffServ domain. It is possible that not only the network congestion status is notified to end-host video applications but also a reactive QoS mapping control is triggeredat the ingress side. NS 2-based simulation results will be
presented to show the enhanced performance of the QoS mapping control framework.
