Course content

Stochastic models of traffic sources, resource demand and user behavior, models of nodes, channels and networks. Transforms. Classical Markovian models. Multidimensional models. 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.

Learning outcome

The course gives an introduction to a probabilistic description of traffic processes in information and communication systems aimed at analysis, measurements and dimensioning. Classical models and methods are taught, but the course also gives an introduction to models and methods for the Internet.

Learning methods and activities

Lectures and voluntary exercises. There is a mandatory semester assignment which requires approval. All teaching material including slides, exercises, and semester assignment is available in English. At a re-sit examination the exam may be changed from written to oral.
