Conoscenze e abilità da conseguire

Acquisition of skills in fundamental mathematical models and methodologies for performance evaluation and dimensioning of communication networks, and related applications to network design. Knowledge of main network models, quality of service mechanisms, control and management techniques and protocols for traffic and service engineering in evolving and emerging network scenarios, with applications to practical case studies.

Metodi didattici

Theoretical lectures and numerical exercises.

Exercises on practical daily situations.

Recorded lectures will be available upon request.

Modalità di verifica e valutazione dell'apprendimento

Written exercise to test the ability to solve new design problems by applications of the methodologies explained in the course.

The oral exam will immediately follow the written part and will check the ability of the student to elaborate the demonstrations of the theorems and to explain motivations and reasoning in support of network design methodologies. 

The highest scores will require, in addition to correctness, appropriate reporting and good speech organization.

Strumenti a supporto della didattica
