MODULE N° 16: Traffic Models for Network Performance Evaluation
Teachers: Prof. ALFIO LOMBARDO, Università di Catania
Ing. GIOVANNI SCHEMBRA, Università di Catania
Syllabus: The target of the course is to provide a unified treatment of both real traffic sources computer networks have to support in the next future, and the teletraffic models usually used in a communication system design process. Moreover the course illustrates some relevant examples aimed at introducing analytical techniques which can be effectively used in the performance evaluation of a network device loaded by the above traffic sources. The teletraffic models discussed are applied to a classical case study, i.e. the performance evaluation of a multiplexer, in order to provide an overview of possible solutions of the related queuing system. Finally, the course presents a number of tools for measured-based traffic modelling and performance evaluation.
