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.
