Computer Engineering - Academic year 2016-17

[Objectives] [Lecturers] [Course outline, material, and schedule] [Lab assignments] [Exams] [Bibliography]


The course presents advanced topics concerning computer networks. Specifically, it presents and discusses widely deployed technologies and offered services, with the aim of providing the knowledge for wisely making technical choices when in charge of network design and operation.


This page refers to to different courses, which present the same topics but are taught in different languages. Specifically,

Those courses present the same topics, make use the same set of slides, share the same learning material (slides, assignments, labs) and the same web site, have the same lecturers. However, lectures (and the exam) will be given in either English (for CNTS) or Italian (for TSR).


Lab assistants

  • Ing. Roberto Bonafiglia (roberto.bonafiglia[at], tel 011 090 7098
  • Ing. Amedeo Sapio (amedeo.sapio[at], tel 011 090 7098

Lab assignments

The course includes some practical assignments on the main topics covered during classes. The Lab assignments allow students experimenting mechanisms and protocols covered during class with the objective of facilitating their learning. Students are strongly encouraged to take advantage of this unique opportunity by not only being present, but carefully going through all the proposed exercises striving to deeply understand what is being observed and ask the instructor for clarification and hints whenever they cannot make sense of what they see. Students will not be required to hand in the outcome of their lab experiences or write a report. However, lab experiences are integral part of the course and it is possible that the exams contain questions related to their content. Most of the suggested experiments can be carried out on any networked computer, hence without going to the lab in the appointed hours. Also part of the proposed experiments require the use of the Dyn@NG network simulator: three instances are available at (please spread the load on those machines during the lab experience hours). However, during schedule hours assistance will be available in the lab to help with possible difficulties and issues.


The type of test (written test, or oral test, or a combination of written and oral test) depends on the number of students taking the exam and will be specified for each scheduled date. Given the high number of students taking the course, in the vast majority of cases the exam will be in a written form.

A written test consists of a set of questions (1 to 4), which might include solving practical problems and writing short essays on specific topics discussed during the lectures, determines the grade. Sample questions are available in Italian (for TSR) and English (for CNTS). Some of the previous exam papers are available.

  • Outcome of the March 3rd TSR and CNTS written tests is available. The discussion of the tests will take place on March 7th in the Sala Colloqui in front of the DAUIN entrance on the fourth floor on top of the Student Office (Segreteria Studenti).
