Designing the simulative evaluation of an architecture for supporting QoS on a large scale

ABSTRACT

The EuQoS system is a complete QoS system, scalable to large dimensions and addressing QoS at all relevant layers, which has been developed within the framework of the IST-EuQoS project. Its design has been aided by a considerable amount of modeling and simulation work, aimed at testing the various QoS mechanisms devised and their interaction. This paper describes the modeling and simulation work done in the framework of the project. We describe the three simulation models which have been developed, based on the different timescales at which the QoS mechanisms have effect. Furthermore, as a sample case of performance evaluation, involving different simulators, we describe the performance evaluation of the EuQoS signaling subsystem.
