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;
-- reference models: ISO-OSI and TCP/IP;
-- circuit-switched and packet-switched networks;
-- connection-oriented services and acknowledged services;
-- flow control: stop-and-wait and sliding-window (go-back-N and Selective Repeat);
-- shaping and policing: leaky bucket and token bucket.

* The Physical Level:
-- transmission media and cable organization;
-- transmission type;
-- information representation (modulation);
-- multiplexing techniques (TDM, FDM, CDM) and multiple access (TDMA, FDMA, CDMA);
-- Fourier analysis and theorem of Nyquist and Shannon;
-- access networks (POTS, ISDN, ADSL, Fibre Channel, PON, Frame Relay, ATM, optical networks);
-- isochronous networks (PDH, SONET/SDH).

* The Data-Link Level:
-- aims and services;
-- framing;
-- examples: HDLC, SLIP and PPP.

* IEEE 802.X standards:
-- topologies and protocols: Ethernet, fast Ethernet, gigabit Ethernet, 10 gigabit Ethernet
-- the MAC sub-layer: Aloha, CSMA, CSMA/CD, CSMA/CA;
-- the LLC sub-layer;
-- bridge, switch and spanning-tree;
-- virtual LAN;
-- wireless LAN.

* The Network Level:
-- aims and services;
-- static routing and dynamic routing (distance vector, link state routing);
-- hierarchical routing;
-- the IP protocol:
---- packet format;
---- address format and use, netmask, ARP and RARP;
---- dynamic host configuration protocol (DHCP);
---- Internet control management protocol (ICMP);
---- interior-gateway protocols (RIP, IGRP, EIGRP, OSPF)
---- exterior-gateway protocols (BGP);
---- class-less inter-domain routing (CIDR);
---- IPv6;
-- layer-3 switch.

* The Transport Level:
-- aims and services;
-- TCP (3-way handshaking, flow control, retransmission, congestion control);
-- UDP;
-- secure socket layer (SSL);
-- firewall, NAT and PAT.

* The Application Level:
-- Domain Name Service (DNS),
-- the client/server model;
-- File Transfer Protocol (FTP);
-- electronic mail (SMTP, POP3 e IMAP);
-- World Wide Web (HTTP, HTTPS, CGI);
-- Simple Network Management Protocol (SNMP);
-- Secure Shell (SSH).

* Geographical networks:
-- classification and protocols;
-- virtual private networks.
