DESIGN OF COMMUNICATION NETWORKS AND SYSTEMS
Academic Year 2022/2023 - Teacher: SALVATORE RIOLOExpected Learning Outcomes
The objective of the course is to develop skills in terms of design of communication networks and systems, including VoIP systems, structured cabling, and fiber optic systems. In addition to traditional communication systems, the course aims to provide students with skills needed for designing fifth and sixth generation networks, including Software Defined Network (SDN) / Network Function Virtualization (NFV) paradigms and the application of simple machine learning techniques for network and service management.
Knowledge and understanding
By exploiting the knowledge acquired, the student will be able to identify the main problems and solutions for the design of a communication network or system.
Applying knowledge and understanding
At the end of the course, students will be provided with a) skills in terms of designing a Local Area Network (LAN) or a Wide Area Network (WAN) b) knowledge of the legislation related to electronic communications and ICT services c) skills needed for designing fifth and sixth generation networks, including SDN/NFV paradigms and basic knowledge of machine learning techniques.
Making judgements
Starting from technical specifications, the student will be able to design communication networks and systems by making proper design choices autonomously. Numerical exercises, computer simulations and the development of design projects will refine the making judgement skill.
Communication skills
The student will improve the technical language and will be able to interact with colleagues of a teamwork to discuss the proper solutions to a specific design problem. To this aim, during the laboratory lessons, students will be grouped in small teams.
Learning skills
Students can broaden their knowledge through the study of recommended textbooks or scientific papers published on specialized journals.
Course Structure
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
