Abstract

This paper deals with a Differentiated Services test-bed, developed in Alcatel Labs in order to evaluate and compare the performance offered by three different queuing policies, namely FIFO, Priority Queuing and Custom Queuing, when supporting Voice over IP traffic. A Premium class has been assigned to voice traffic, while Best Effort class traffics have been considered as disturbing traffic and they have been generated by means of suitable TCP and UDP software tools. Performance comparisons have been developed for the considered queuing schemes. In particular, Priority Queuing has resulted to be the best solution for Premium class quality in the developed test-bed. For this scheme a suitable analytical approach has been also proposed and validated by comparing analytical predictions with experimental results.
