PRESENTAZIONE

The Internet is a network composed of different transmission media, such as fiber optic cable, coaxial cable, satellites, radio, and copper wire, and carries a broad range of services and information technology applications into homes, businesses, schools, and hospitals such as World Wide Web (WWW), electronic mail, telephony, and file sharing. The deep comprehension of the behavior of the Internet Applications is not only an essential know-how of a modern ICT engineer but also the basic element to design new services for users so generating new opportunities, facilities, and ideas.

OBIETTIVI FORMATIVI

Internet applications: revision of UDP and TCP protocols, ICMP, IGMP, BOOTP and DHCP, DNS, FTP, SMTP, POP, IMAP, SNMP, and HTTP. Multimedia Internet applications such as the VoIP protocol, concepts of public and private networks including the NAT solution.

OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO

The lectures are aimed at providing theoretical and practical knowledge about the most important Internet applications. The course will give a general picture how a client-server program is designed also giving simple example codes of its implementation to make clearer the comprehension of the rest of the Course. The remainder of the lectures will provide details of each single analysed protocol so to allow a full comprehension and a future possible design of solutions acting at application layer. In detail: the course will focus on Client/Server Model, Socket Interface, DHCP, DNS, TELNET, FTP, SMTP, POP, IMAP, SNMP, and HTTP.
