Moment methods and imbedded techniques. Systems with priorities. Open and closed queueing networks. Markov modulated processes, fluid flow models. Case studies of broadband networks, mobile networks and Internet using analytical models and simulation. Internet traffic, characterization, measurement methods and statistical problems.

A. Knowledge:
1) A foundational understanding of terminology and concepts used in describing traffic processes in computer and telecommunication networks / systems, aimed at analysis, measurements and dimensioning.
2) An in-depth understanding of the most fundamental models and methods in classical queueing analysis for computer and telecommunication networks / systems.
3) A basic understanding of traffic analysis models and methods for Internet networks.

B. Skill:
1) To be able to communicate, reason and creatively think about traffic issues in computer and telecommunication networks / systems.
2) To be able to model and evaluate systems quantitatively with respect to traffic performance measures by using the acquired knowledge.

Lectures and voluntary exercises. There is a mandatory semester assignment which must be approved to get access to the final exam. If there is a re-sit examination, the examination form may be changed from written to oral.
