Introduction

This course is an in-depth extension of the First Degree course entitled Organization of Operating Systems and Networks. The focus is on mobile IP, TCP, on the IPv6 and on intra-domain (OSPF) and inter-domain (BGP-4) routing protocols.

The description of these protocols is at a level of abstraction such that the lecturers can highlight and go into depth into the most important aspects and ignore any details that are not relevant at a conceptual level. The main focus will be on the criteria followed by designers in designing the various protocols, rather than on a detailed description of the messages exchanged by these protocols in terms of bits and bytes. With this background, students should then be able not only to easily follow the evolution of the above mentioned protocols but also to learn about and understand new ones.

Recommended reading

Computer Networks - A System Approach, di Larry L. Petereson e Bruce S. Davie, Third Edition, Morgan Kaufman, ISBN 1-55860-577-0, http://www.mkp.com/.

Other books and articles will be suggested during the course itself. The programme for 2006/2007 can be found here.

Organization of lessons

Theoretical lessons will alternate with tests, but the order will not be established beforehand. Tests will generally take place at the end of the theoretical part. Lessons will start punctually and there will be a 15 minute break between the first and second hours. The lecturer/professor holding the course will be available during the break between the two hours, and on Thursday mornings from 11.30 to 13.30 in his room at the department (Dipartimento di Ingegneria dell'Informazione: Elettronica, Informatica e Telecomunicazioni - Sezione Informatica, via Diotisalvi, 2).

You can find the lesson plan calendar here (PDF - in Italian).

Organization of exams

There will be a written exam followed by an oral exam. The written generally consists in two exercises to be completed in two hours. Having done the written, students will then have a choice of dates for the oral. However, the written and oral exams must be done in the same session (i.e. both in the winter, or both in the summer, or in the fall).

Students can decide to repeat the written exam as many times as they wish. However, their final mark will be the mark that they obtain the last time they attempt the exam. This means that students cannot decide to accept the mark they obtained in a previous written exam even if they then perform worse in a subsequent exam.

We advise students to follow all the lessons and to take the exam before the end of the relevant semester.
