Un esempio di soluzione è disponibile alla pagina dei testi degli esami precedenti. La discussione dell'esame si terra il 8 settembre alle ore 18:15 presso la Sala Colloqui (al IV piano sopra la segreteria studenti). Si noti che, ad eccezione degli studenti la cui matricola sia eventualmente evidenziata in grassetto nella tabella sopra, non è necessario partecipare ai fini del superamento dell'esame: si tratta di un'occasione per fare eventuali domande e ricevere chiarimenti (si prega di evitare di inviare domande per e-mail). In caso si desiderasse ripetere l'esame nonostante lo si sia superato, è sufficiente inviare un e-mail dal vostro indirizzo del Politecnico. Diversamente i voti verranno pubblicati sul registro elettronico nei giorni successivi la discussione e registrati qualche giorno dopo.

Agli studenti la cui matricola sia stata evidenziata in grassetto è richiesto un colloquio per fornire chiarimenti sulle risposte fornite senza il quale l'esame non può essere superato. Per quelli la cui matricola sia in corsivo un colloquio è facolatativo, ma può portare ad un miglioramento del voto.

A sample solution is available on the past exam paper page. A discussion of the exam will take place at 5:45 pm on September 8th in Sala Colloqui, located on the 4th floor above the Student Registry (Segreteria Studenti). Participation to this event is not required to pass the exam, with the exception of the students whose ID is possibly highlighted in bold face in the above table: it is an opportunity for possibly asking questions and obtain clarifications (please avoid asking questions by e-mail). In case you wish to take the exam again although you have passed it, please just send an e-mail from your Politecnico address. Otherwise, grades will be published through the teaching portal in the days immediately following  the discussion session and registered right afterwards.

Clarifications on the way the questions were answered are needed by the students (if any) whose ID is in bold face and the exam cannot be passed unless they come and talk to me during the exam discussion session. Students (if any) whose ID is italicized are not strictly required to have an additional discussion, but doing so might improve the evaluation of their exam.

Past exam papers

Below are exam papers used in previous TSR and CNTS exams:

Academic year 2015/16:

Academic year 2014/15:

Academic year 2013/14:

Course outline, materials, and calendar

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. 

Course outline and material:
Recordings of lectures will be made available on the teaching portal.

Internet Protocol version 6

Multi-Protocol Label Switching (MPLS)colorblack&white

  • Original idea and basic principles
  • Multi-protocol Lambda Switching
  • Generalized MPLS (GMPLS)
  • Forwarding table exercises (TSR, CNTS)

Audio and video transmission on packet networks

Virtual Private Networks (VPN): protocols and architectures for both customer-provisioned and provider-provisioned solutions

Technologies for data communication in wide-area-networks: ATM, Frame Relay, SONet/SDH. 

 

Material for Lab Experiences:
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.

Lecture notes shared by students:

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.
