This paper presents an implementation architecture based on per flow queueing that is capable of achieving QoS provisioning for future integrated services networks consisting of the guaranteed service (GS), the controlled-load (CL), and the best-effort (BE) service classes. We propose several novel traffic management mechanisms, including Adaptive Rate allocation for Controlled-load (ARC), a hybrid model-based and measurement-based admission control algorithm for GS and CL flows, and a Quasi-Pushout Plus (QPO+) packet discarding mechanism. Simulation results show that our architecture and algorithms provide hard QoS guarantee to GS flows under all conditions, consistent (soft) QoS to CL flows under both light and heavy load conditions, and effective control of negative impact from non-conforming CL flows. Our architecture and algorithms also resolve several issues associated with the traditional class-based approach.
