OVERVIEW

The class aims at deepening the knowledge of the main architectural aspects and protocols at the basis of the Internet and its evolution. It is essentially organized in four parts, addressing IP and TCP and related protocols, WiFi, protocols and techniques for advanced networking (network management, Quality of Service, multimedia services over best effort networks, virtualisation); and fundamentals of telecommunications network security.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide students with all the basic notions required to understand, design, configure, and manage a telecommunications network based on Internet technology. Along with these notions, the basic concepts of digital security are also introduced, with particular emphasis on encryption techniques. To this end, the following topics, in particular, are presented and analyzed: • Introduction to Internet Architecture and Protocols: IPv4 (management of IP addresses); IP routing algorithms and protocols. Multicast; IPv6; UDP/TCP; Flow and congestion control in packet networks; hints at the Application layer • Network and Computer Security: Basic concepts; Introduction to Encryption, Symmetric Encryption: DES and AES, Operation Modes, Flow Encryption, Asymmetric Encryption. • Wireless LAN Architecture and protocols: Wi-Fi (IEEE 802.11) • Quality of Service (QoS) in IP Networks: Introduction to QoS in IP networks; Differentiated Services and Integrated Services IETF Architectures; ReSerVation Protocol (RSVP); Multi-Protocol Label Switching (MPLS) • Multimedia services over the Internet: Voice and Video over IP; Real Time Protocol (RTP) and Session Description Protocol (SDP).

AIMS AND LEARNING OUTCOMES

The main goal of the classes is to provide a deeper knowledge of the Internet architercture and of some of the main underlying protocols, starting from the basic elements acquired in an undergraduate course in the ICT (Information and Communication Technology) area. More specifically, after reviewing IPv4 addressing principles and related protocols at the network layer, the lectures will touch IPv6, routing algorithms and protocols, and multicast; then, congestion control techniques and their implementations in TCP will be considered. The wireless networking part treats WiFi (IEEE 802.11). Regarding advanced network functions and protocols, the main concepts are introduced regarding network management, Quality of Service, multimedia services, and virtualization environments. The final part provides an introduction to cybersecurity in telecommunications networks.

PREREQUISITES

Students are expected to have a base background in network protocols and reference layered architectures.

TEACHING METHODS

Combination of traditional lectures (40+40 hours) and laboratory experimental activities (approx. 20 hours).

EXAM DESCRIPTION

Multi-answer test for accessing the oral examination, and oral examination.

ASSESSMENT METHODS

The multi-answer test is devoted to assess whether the students have actually learnt the basic foundations of Internet protocols and architectures. The oral exam is aimed at evaluting the synthsis, reasoning, and critical capacities of studens on the topics covered by the lectures.
