Language of instruction
The Internet architecture is presented, in particular the local and geographical network architecture. The TCP/IP Internet protocol suite and the Network Services are illustrated in detail: SSH, FTP, Telnet, NIS, NFS, Automount, Email, HTTP, SNMP, Firewall and Network Security. Some case studies are illustrated.

Educational objectives
The main objective of the course is to introduce students to the study of local and geographical networks, particularly the Internet and the Services that are the foundation of the extraordinary evolution of communication and access to information, in order to to play a leading role in the ICT scenario.The main knowledge gained will be:Topology and access methods for local networks, particularly for the Ethernet Technologies for the realization of wide area networks, in particular Frame Relay and ATM Autonomous Systems and Routing Protocols, both Interior Gateway Protocol (OSPF, RIP) and Exterior Gateway Protocol (BGP) Protocol version 4 and version 6 Family of protocols TCP / IP Internet Network Services: their design and implementation Firewall and network security Monitoring of networks and services The main acquired skills (i.e. the ability to apply the knowledge) are:Ability to design and implement a data transmission network, avoiding the possible critical issues Ability to design and implement the Internet network services, with the capacity of avoiding the main problems Ability to plan and implement efficiently the network security Ability to plan and implement the monitoring of network and services to prevent potential problems and interruptions.
No prerequisites are required to the student to attend the course; however the basic knowledge of Internet Services it  is expected to be known by all students.A strong knowledge of open source operating systems like Linux facilitates the acquisition of the concepts presented during classes. Furthermore, examples and use cases will be presented, aimed at facilitating the learning of the concepts covered during classes.
Teaching methods
Lectures using multimedia tools (slides, video, etc). Exercise in the computer room.
Other information
The teacher may deliver classes, labs and exams in english, french and spanish.The teacher is available at adopting during the exam the following languages: English, French and Spanish
Learning verification modality
The exam includes a written test at the computer, based on the  Exams Online system, wich presents to the student a series of tests involving different types of response: multiple choice and / or multiple response and / or drag and drop and / or open-ended.An oral exam of about 20 minutes, in which the student must demonstrate the knowledge of the required concepts, and the ability to organize the concepts to be properly illustrated.
Extended program
The architecture of Local and Geographical Area Networks is presented, starting from the ISO OSI Reference Model and describing the local networks architecture (Ethernet and its variants), the geographical networks (Frame Relay and ATM), and MAN networks.
The TCP/IP Protocol suite is carefully described, comparing the various protocols with the ISO OSI Reference model. The IP protocl version 4 and version 6 are presented.
The main Internet Services are presented: SSH, FTP, Telnet, NIS, NFS, Automount, Email (Transport protocol SMTP and Mail User Agent), HTTP, SNMP, Firewall and Network Security.
The Autonomous System concept is illustrated and the dynamic routing protocols are presented: OSPF and RIP as Internat Gateway Protocols (IGP), and BGP as External Gateway Protocol (EGP).
The main configuration issues and files are presented and discussed. Configuration parameters are illustrated and some typical case studies are also presented.
The Internet governance is presented, illustrating the main milestones of the Internet evolution.
