The course consists mainly of classroom lectures. These are complemented by supervised classroom exercise sessions in which students can apply the concepts learned during the lectures to realistic use cases and discuss them with the instructor. Finally, for a subset of the topics, the course includes lab sessions to help retaining the concepts learned during the lectures by observing the corresponding technologies in action. Lab sessions cover the following topics: - Configuration and observing the operation of IPv4 and IPv6 hosts and routers - Traffic analysis in access VPN solutions.

Due to the advanced nature of the topics addressed by the course, they are not covered by a single textbook or a limited number of textbooks. The course website provides, besides the overheads used during lectures, a list of links to documents publicly available over the Internet and references to book chapters that address the various topics discussed during lectures.

Modalità di esame: Test informatizzato in laboratorio; Prova orale facoltativa;

Computer network technologies and services

1-hour written exam, including 30 multiple-choice questions. The following evaluation criteria will be applied: correct answer: 1 point, wrong answer: -0.5 points, no answer provided: 0 points. A mark of the written test larger than or equal to 23/30 will give the right to take integrative oral test. The oral test is elective, however marks larger than 26/30 in the written test will result in a final grade of 26/30 when electing not to take an oral test. In both exams, the knowledge level of the concepts and topics presented during lectures will be evaluated, by means of both theoretical questions and numerical exercises, possibly presented in multiple-choice question form.
