QoS, Proportional DiffServ, Scheduling


A robust adaptive scheduler for proportional delay differ entiation services is presented. Proportional services are further policed by a class based packet dropper. Our pro posed combination of the adaptive scheduler and the packet dropper treats the traffic classes proportionally in terms of three QoS metrics: bandwidth, delay, and packet loss, si multaneously. Simulation experiments with bursty traffic validate our claim.
