This course addresses the topics of Quality of Service (QoS) and performance evaluation of computer networks efficiency in networks. In the QoS part, the course outlines all basic concepts of QoS of computer networks such as models, protocols, marking and classification techniques. In the performance part the course aims to introduce fundamental concepts of performance evaluation of computer systems and networks. Then, the course continues with some fundamental performance analysis techniques including methods for performance measurement, performance metrics, monitoring, experimental design, and system modeling. Other topics include: comparing two or more systems; system tuning; performance bottleneck identification; characterizing the load on the system (workload characterization); determining the number and size of components (capacity planning); predicting the performance at future loads (forecasting); queuing theory, mean value analysis, and modelling. The course concludes with applications of the learned concepts to measure the performances of computer systems like communication networks.

Dissertation combines the educational theory and practice to create a learning experience that enables the development of skills that can be applied to complicated real-world problems. The dissertation project module commences with a research methods training component during which students will be given instruction and guidance on the planning and organization of their work. During the course of the research methods training students will also be expected to start formulating their project. The project itself, will be individually or jointly supervised as soon as the committee approves the proposal. There is an interim assessment point during the course of the project where students submit their project specification and design. At the end of the project students are expected to submit a dissertation describing their project.
