Learning outcomes

This class aims at describing the basic concepts and the main design methodologies of the modern communication networks, both local and geographical.

Syllabus

32 hours covering the following topics:

* General concepts:
-- classification: WAN, LAN, PAN;
-- topologies;
-- shaping and policing: leaky bucket and token bucket;
-- circuit-switched and packet-switched networks;
-- reference models: ISO-OSI and TCP/IP;
-- connection-oriented services and acknowledged services;
-- flow control: stop-and-wait and sliding-window (go-back-N and Selective Repeat);
-- standardization bodies.

* The Physical Level:
-- fundamentals of communication theory;
-- Fourier analysis and theorem of Nyquist and Shannon;
-- information representation (modulation);
-- transmission enemies;
-- transmission media;

-- modem e xDSL;
-- wiring rules.

* The Data-Link Level:
-- aims and services;
-- framing;
-- error detection;
-- channel access methods;
-- PPP protocol.

* IEEE 802.X standards:
-- addressing;
-- topologies and protocols: Ethernet, fast Ethernet, gigabit Ethernet, 10 gigabit Ethernet
-- the MAC sub-layer: CSMA/CD, CSMA/CA;

---- router architecture and functions;
---- static routing and dynamic routing (distance vector, link state routing);
---- interior-gateway protocols (RIP, IGRP, EIGRP, OSPF)
---- exterior-gateway protocols (BGP);
---- Internet control management protocol (ICMP);
-- Virtual LAN.

* The Transport Level:

Assessment methods and criteria

Examination consists of a written test with questions about the theory and practice part of the class and numerical exercises.

A project can be developed in small groups of max 3 people.

The result of the project (max 3 points) is summed to the result of the written test.
