Design and implementation of a new adaptive algorithm for dynamic bandwidth allocation

Abstract

This paper considers dynamic bandwidth management with the aim to support QoS transfer for traffic classes that access a Differentiated Services domain. Particular attention is given to the feasibility of the bandwidth management approach by investigating algorithms that are easy to design in relation to traffic unpredictability. A new algorithm is proposed characterized by few design parameters whose main effects on performance are mostly independent of each other. Evaluations are developed with the aim to meet quality of service constraints for real time traffic and achieve a trade off between efficiency and scalability. Implementation of the algorithm and related measurements are also presented. © Springer-Verlag Berlin Heidelberg 2004.
