The course focuses on the complex technological infrastructures being deployed
nowadays. Particular emphasis will be given to the role of
their hardware and software components and to the issues related to performance
and Quality of Service (QoS). The course will introduce the
techniques and tools for analyzing and predicting the performance
of the infrastructures and discuss some case studies.
At the end of the course,
students will have enough competence to identify the components that limit the
performance of complex technological infrastrustures.
