Subject fundamentals
The course is taught in English.


The course focuses on network management, planning and quality of service provisionig. Class lectures will introduce techniques to support heterogeneous traffic (voice, video, data) on a single network infrastructure. Particular attention is devoted to algorithms and to standardization efforts.
Expected learning outcomes
The student will gain knowledge on algorithms and techniques needed to run and manage computer networks while providing a proper level of quality to users. Besides the knowledge on specific algorithms, the students will be required to be able to put the algorithms in the proper newtworking framework, which includes the used technology, the user-service goals, the user traffic characterization and control, and the quality of service parameters. Different service and quality of service models will be discussed and analyzed. The students will gain the ability to critically analyze standardization efforts, to understand the reasons that drove the design choice in standards. A significant ability in discussing algorithm pros and cons is required in the final exam and will be gained during lectures through group discussions.
The ability to apply the gained knowledge will be verified through class exercise and discussions, as well as during the oral examination. The oral examination will also help students in improving their communication skills.

Basic knowledge of telecommunication and computer networks architectures. Basic knowledge of signal processing techniques.
