A robust adaptive scheduler for proportional delay differentiation services is presented. Proportional services are further policed by a class-based packet dropper. Our proposed combination of the adaptive scheduler and the packet dropper treats the traffic classes proportionally in terms of three quality of service (QoS) metrics: bandwidth, delay, and packet loss, simultaneously. Traffic types used to study the performance of the scheme ranges from ordinary FTP data to bursty Pareto traffic. Numerical results validate our claim that regardless of the network traffic characteristics, especially burstiness, the adaptive delay scheduler combined with the packet dropper can effectively differentiate services in terms of delay, bandwidth, and loss simultaneously. In addition, our proposed scheme showed on an average 11% improvement in performance when compared to the scheme proposed in C. Dovrolis, D. Stiliadis, & P. Ramanathan, Proportional differentiated services: Delay differentiation and packet scheduling, IEEE/ACM Transactions on Networking, 10(1), 2002, 12--26.
