Characterization and Performance Evaluation for Proportional Delay Differentiated Services
In this paper, we consider a proportional delay model for Internet differentiated services. Under this model, an ISP can control the “spacing” of waiting times between different classes of traffic. Specifically, the ISP tries to ensure that the average waiting time of class traffic relative to that of class traffic is consistently a specifiable ratio. If the ratio is less than one, the ISP can ...
متن کاملDynamic Priority Scheduling for Proportional Delay Differentiated Services
Recent results on the proportional di erentiation model show that waiting time priority scheduling can be applied to implement proportional delay di erentiatied services reasonably well under limited conditions. While earlier research focused on heavy load conditions only, more recent results provide insights into waiting time priority scheduling under moderate load conditions also, but the app...
متن کاملA combined delay and throughput proportional scheduling scheme for differentiated services
The proportional differentiation model is a newly introduced approach for differentiated services networks. This paper proposes and evaluates a scheduling mechanism for the combined control of delay and throughput metrics, according to the proportional differentiation model. The scheme is based on the well known Little’s Law. A moving window averaging mechanism and an active queue management sc...
متن کاملDynamic class selection and class provisioning in proportional differentiated services
The relative diierentiation architecture does not require per-ow state at the network core or edges, nor admission control, but it can only provide higher classes with better service than lower classes. A central premise in the relative diierentiation architecture is that users with an absolute QoS requirement can dynamically search for a class which provides the desired QoS level. In the rst p...
متن کاملPerformance Evaluation of the Particle Swarm Optimized Fuzzy Logic Congestion Detection Mechanism in Proportional Differentiated Services IP Networks
Abstract—A Particle Swarm optimized Fuzzy Logic Congestion Detection (FLCD) was recently proposed for best-effort service networks. This algorithm synergically combines the good characteristics of traditional Active Queue Management (AQM) algorithms and fuzzy logic based AQM algorithms. Its membership functions are designed automatically by using a Multi-objective Particle Swarm Optimization (M...
