LEARNING OUTCOMES

• Review of the Internet Architecture and Protocols o IPv4 review (management of IP addresses); IP routing algorithms and protocols review; Multicast; IPv6; UDP/TCP; Flow and congestion control in packet networks; Application layer • Network and Computer Security o Basic concepts; Algorithms; Standard protocols; Vulnerability of networks; Summary of the local (Italian) regulations; Computer security • Wireless Network architecture and Protocols o Wi-Fi (IEEE 802.11); Bluetooth (IEEE 802.15.1) • Quality of Service (QoS) in IP Networks o 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 o 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.

TEACHING METHODS

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