ECTS Credits 2,5 + 2,5
Language English

We introduce the term quality-of-service (QoS), discuss important approaches to achieve certain degrees of QoS, and show how the implementation in computer networks. Then a number of methodologies to assess and design systems with respect to their QoS:

  • network planning and optimization,

  • network simulation,

  • stochastic analysis (Markov chains, non-Markovian models, queuing systems),

  • deterministic analysis with network calculus to determine QoS guarantees

  • measurements (hardware, software, and hybrid monitoring, benchmarks).

All methods are illustrated by examples.
