Abstract :
In this paper, we present a delay differentiation based QoS architecture for supporting real-time multimedia services in the core-stateless IP networks. The key component of our approach is a three-level class-based scheduling scheme. Based upon it, we propose the Delay Differentiation with Earliest-Deadline-First (DD-EDF) QoS architecture. Simulation shows that our approach can achieve better end-to-end/per-hop average queueing delay performance with higher link utilization, when compared with the scheme without DD-EDF.
