Since the courses Computer Network Technologies and Services and Tecnologie e Servizi di Rete have the same content, the outline is provided here for both.
Recordings of lectures will be made available on the teaching portal.

This section contains the assignments for all the three laboratories and some introductory material regarding how to use the Dyn@ng network simulator (available on three different servers, one of which is preferable as it has most resources). TSR students must attend lab sessions in two separate groups, as specified in the course calendar, based on the initial of their last name: A to K and L to Z.
- Introduction to lab assignments with GNS3
- Basic configuration of Cisco Routers
- The Dyn@NG Virtual Lab (slides)
- Dyn@NG Tutorial
- Lab session #1 - IPv6 on hosts
- Lab session #2 - IPv6 on routers [Example of solution]
- Lab session #3 - SIP
- Lab session #4 - MPLS [Cisco guide for dynamic and static configuration, sample solution]
- Lab session #5 - VPN
The lecture notes and other material provided in this section was compiled by students that nicely offered to share it with other students having taken the same or future editions of the course. The material is available to the course website because it might be helpful. However, it is by no means to be considered as a reference in terms of set of topics addressed in the course (and required to pass the exam), level of detail provided (and required to pass the exam), accuracy of information contained.
