ABSTRACT A robust adaptive scheduler for proportional delay differentiation services is
presented. Proportional services are further policed by a class based packet dropper. Our …

Internet applications and users have very diverse service expectations, making the current
same-service-to-all model inadequate and limiting. In the relative differentiated services …

Abstract Proportional Differentiated Services can be provisioned in terms of bandwidth,
delay, or packet loss. Several studies contributed schedulers and packet droppers that …

One of the important issues in building differentiated services is how to support relative
differentiated queueing delay services for packets from different classes. This paper …

The proportional differentiation model provides the network operator with the'tuning knobs'
for adjusting the per-hop quality-of-service (QoS) ratios between classes, independent of the …

The proportional delay differentiation (PDD) model provides a consistent packet delay
differentiation between classes of service. So far, present schedulers performing the PDD …

Proportional delay differentiation (PDD) model is an important approach to relative
differentiated services provisioning on the Internet. It aims to maintain pre-specified packet …

The proportional delay differentiation (PDD) model is an important approach for relative
differentiated services provisioning on the Internet. It aims to maintain pre-specified packet …

Proportional service differentiation models are simple and effective approaches to service
differentiation in Internet. Schedulers for delay differentiation are important elements of these …

The proportional delay differentiation model provides controllable and predictable delay
differentiation, that is, the packet delay proportion between two classes of services is …
