Abstract

The proportional service model has gained attention recently as an effective solution for quantitative service differentiation in IP networks. In particular, this differentiation scheme is controllable, consistent and scalable. Thus, it gives network operators convenient management of services and resources even in a large-scale network. In this article we give an overview of recent research efforts on this QoS model. Details about implementation strategies for various QoS metrics are provided. We also discuss how to achieve absolute service bounds in this relative differentiation model with different approaches. Several problems such as feasibility in differentiation are mentioned as open research issues at the end.
