EP2200 Queuing Theory and Teletraffic Systems 7.5 credits

Köteori och teletrafiksystem

Queuing theory is the basis for performance evaluation and dimensioning of telecommunication and computer communication networks, road traffic systems, and transport systems in general. This course treats queuing systems with an emphasis on the classical models. The theory is illustrated by problems drawn from telecommunication and computer communication.

Intended learning outcomes

The course gives a basic knowledge in modelling and analysis of queuing systems with applications to communication systems.

Course main content

This course includes the classical theory for queuing systems:

  • Basic terminology, Kendall’s notation and Little’s theorem.
  • Discrete and continuous time Markov chains, birth-death processes, and the Poisson process.
  • 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.


For single course students: 120 credits and documented proficiency in English B or equivalent

Recommended prerequisites

SF1901 Probability Theory and Statistics, or similar. Basic knowledge in networking is helpful, but not mandatory.
