MASSARI LUISA - 6 ECTS

The course provides an introduction on computer networks, and it is attended by students with different backgrouds (electronics, computer science, bioengineering). Hence no particular knowledge in the field of computer networks or programming skills are required, but a basic knowledge of mathematical analysis and binary computing.

The aim of this course is to introduce key concepts and principles of computer networks; the objective is to give the student familiarity with the behaviour of modern data transmission technologies and the ability of analysing their performance. The Internet architecture and protocols will be used as the primary examples to illustrate the fundamental principles of computer networking.
Lab activity will be on tools for network traffic monitoring and analysis. These activities will allow students to verify theory as well as to gain skills in analysis and configuration of computer networks.

Introduction to computer networks: elements of a network, circuit switching and packet switching, access to the network and transmission media.
Performance: delay and losses in computer networks
Layered communication architectures, definition of protocol, Internet architecture
Basics on application layer.
Transport layer: services, UDP and TCP protocols. Flow control and congestion control. Performance problems: latency, throughput and utilization.
Network layer: switching and forwarding, data plane and control plane. Routing algorithms. Internet protocol, IP addressing and routing in Internet. IPv6
Network monitoring: techniques and tools.

Lectures (hours/year in lecture theatre): 38
Practical class (hours/year in lecture theatre): 14
Practicals / Workshops (hours/year in laboratory): 8

Lectures are followed by practical classes during which students apply and verify theory to practical examples of computer networks architectures.
