Obiettivi dell'insegnamento

The course is intended to provide students with the knowledge and tools necessary to design and plan communication networks. The first part of the course focuses on optical networks: different segments of networks (access, metro and core) are taken into consideration. Design approaches base on mathematical modeling (integer linear programming) and heuristic approaches are discussed. In the second part of the course, traffic theory will be developed for the design of circuit switching networks, and specifically to solve dimensioning problems (Erlang, Engset) and to investigate advanced methodologies for traffic modeling. Specific case studies will be developed to provide examples of the different design approaches.

Modalità di valutazione

The verification of knowledge for the course content consists in a test at the end of the course that comprises a written test and, if required, an oral examination on the subjects covered in the course. Projects, to be defined with the professor, can be used to substitute the written and oral examination. A laboratory activity using the software net2plan can be used to complement the final score.

In case of negative evaluation the student is admitted to the following tests of the academic year.
