Internet
Academic Year 2025/2026 - Teacher: Alfio LOMBARDOExpected Learning Outcomes
Ability to design a telematic system
Learn about the Internetworking mechanisms, the architecture and the suite of TCP / IP protocols providing for both best effort and QoS aware services.
Know how to configure the basic functionality of a router / switch; to design an Internet network
Understand today's communication paradigms to manage QoS in the next generation Internet
The student will need to acquire the ability to communicate rationally his knowledge on the subjects covered by the course, mastering the specialized vocabulary in the field.
Ability to read the industry's standard and scientific literature related to Internet technologies.
Course Structure
The course consists of lectures and exercises held in the CDLM laboratory at the Engineering Technological Pole in via Santa Sofia
In case of COVID emergency, lectures will be provided through an appropriate computer platform.
The final exam could be eventually done remotely in case of COVID contingency.

Learning Assessment
Learning Assessment Procedures
The course alternates between theoretical topics and laboratory experiments which, step by step, build an MPLS-based network with quality management to support applications with different performance requirements.
Ongoing assessment no. 1 on topics 1 and 2 with exam value: the ongoing assessment consists of a series of open-ended questions and the design and configuration of an internet network (Laboratory no. 2).
Oral examination
