EP2200 Queuing Theory and Teletraffic Systems 7.5 credits

Note, eventuel collisions with other courses will be handled at the beginning of the course.

Queuing theory is the basis for performance evaluation and dimensioning of communication networks, computing systems, road traffic and transport systems, and other resource sharing systems, like digital health services.

This course treats queuing systems with an emphasis on the classical models. The theory is illustrated by problems drawn from communication and computing.

Content and learning outcomes

Course contents

The classical theory of queueing systems: 

  • Discrete and continuous time Markov chains, birth-death processes, and the Poisson process.
  • Basic terminology of queuing systems, Kendall’s notation and Little’s theorem.
  • Markovian waiting systems with one or more servers, and systems with infinite as well as finite buffers and finite user populations (M/M/).
  • Systems with general service distributions (M/G/1):  the method of stages, Pollaczek-Khinchin mean-value formula and and systems with priority and interrupted service.
  • Loss systems according to Erlang, Engset and Bernoulli.
  • Open and closed queuing networks, Jacksonian networks.

The theory is illustrated by examples from telecommunication and computer communication such as blocking in circuit switched networks, preventive and reactive congestion control, and traffic control for guaranteeing quality of service.

Furthermore, students develop their skills to perform performance analysis of queuing systems and to present the results, using mathematical software and suitable text editors.

Intended learning outcomes

After passing the course, the student should be able to

  • explain the basic theory of Markov-processes and apply the theory to model queuing systems,
  • derive and use analytic models of of Markovian queuing systems, queuing networks and also some simpler non-Markovian systems,
  • explain and use results derived for complex non-Markovian systems,
  • define queuing models of communication or computer systems, and derive the performance of these systems,
  • use adequate tools to present scientific work,

in order to be able to carry out mathematical modeling based performance evaluation of communication, computing, or other resource sharing systems.
