ELEC97090 (EE4-05) Traffic Theory & Queueing Systems


Lecturer(s): Dr Javier Barria

Aims

The aim of this course is to provide students with the opportunity to develop a conceptual framework for modelling and analysing different communication networks (e.g. circuit-switched and packet-switched networks). The course will show, firstly, how to set up such models and, secondly, how to use them in the performance (e.g. QoS) analysis of communication systems.

Learning Outcomes

-Describe and discuss the validity of different performance modelling/assessment techniques.
-Identify different communication system performance issues and formalise them in mathematical terms.
-Describe and discuss the underlying assumptions of the studied modelling/assessment techniques.
-Formaly describe the performance of communication systems using analytical methods (e.g. blocking probabilities and queueing delays)
-Derivate and evaluate performance aspects of queueing systems using different modelling techniques (e.g. Markov chains and fluid flow models).
