Quality of Service in Communications (ST 2021)
|Type of Course||Lecture (2 SWS) + Exercise (2 SWS)|
|ECTS Credits||2,5 + 2,5|
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,
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.
