A telecommunications network is a set of devices and connections that allow the transmission and reception of information between a source and one or more destinations. The Internet is a "network of networks" that connects billions of devices worldwide. The knowledge of the mechanisms that regulate the functioning of a telecommunications network and of the Internet in particular is fundamental for an Information and Communication Technology (ICT) engineer both from a work and cultural point of view.
Basic principles of the telecommunication networks. Multiplexing. Circuit switching, packet switching . Functional architectures and protocols. Internet architecure. Application , transport and network layers. Data link layer. Wired and wireless LAN .
The course aims to provide the fundamental knowledge related to telecommunications networks and, in particular, related to the Internet, exploring the following aspects: structure and classification of a telecommunications network. Concept of switchboard and description of the structure of the telephone network. Internet infrastructure and TCP / IP networks, definition of the main Internet interconnection elements: hubs, switches, routers, gateways, terminals. Main data link layers: IEEE 802.3 / Ethernet, IEEE 802.11, HDLC, Point to Point Protocol (PPP). Internet protocols: IP, TCP, UDP and IP addressing scheme.
The final goal is that, at the end of the course, the student has acquired the basic skills necessary for the evaluation, project and verification of the main elements constituting a modern telecommunications network and the Internet.
Lectures integrated by laboratory trials.
Introduction
Structure of a telecommunications network. Definition of the structure at functional layers, definition of protocol, communication between remote systems.
Classification
Transmission from source to destination with interconnection via router. Definition of circuit and packet switching. Concept of switchboard and description of the structure of the telephone network.
Internet structure
Structure of the Internet and TCP / IP networks, terminals (hosts, end-systems), routers and communication links. ISP (Internet Service Provider) concept: local and regional. Structure of the Internet as a "hierarchical" network. Evaluation criteria of the efficiency of a packet telecommunications network.
The data link layer: information encapsulation
