Internet Networks

Subject description

The subject "Internet Networks" explores a wide range of topics covering basic network concepts, transmission media and network topologies. Students will learn more about the development of communication technologies, ranging from early connection and circuit to modern connectionless and packet approaches. Core topics include various Ethernet technologies such as VLAN and STP, as well as IPv4, IPv6, DHCP, DNS, NAT, and diagnostic tools. We will further explore the area of advanced routing, multicast and QoS basics. We will also delve into the architecture, devices, and operation of both home and operator networks, along with a comprehensive understanding of operator concepts, including broadband access, aggregation, core, and service networks, regulation, net neutrality principles, and business models. Further discussions will include Virtual Private Networks (VPNs) and Software Defined Networks (SDN). In the context of cyber security, we will analyze threats at different layers of network models, the use of firewalls, protection methods, performing penetration tests and ensuring cloud security.

The subject is taught in programs

Objectives and competences

The objective of the course is to provide an overview of concepts, architectures and protocols in modern telecommunication networks. The focus is on network transfer process with internet protocol.

Students will acquire fundamental knowledge and skills in these fields.

Teaching and learning methods

Lectures for theoretical aspects, laboratory exercises and team work for real-case scenarios and problem solving through project work. Part of the pedagogical process will be carried out with the help of ICT technologies and the possiblities they offer.. Study visits and invited lecturers.

Expected study results

After successful completion of the course, students should be able to:

list key technologies of Internet networks,
describe the network technologies in enterprise environments and operator environments,
describe the architecture of enterprise and the architecture of operator networks,
differentiate among functionalities of the layers of communication protocols,
differentiate among functionalities of different protocols for network security provisioning,
configure user, home and enterprise network devices for basic connectivity and use the adequate combinations of technologies,
configure operator network devices for basic connectivity and use the adequate combinations of technologies,
compare concepts, architectures and functionalities of home, enterprise and operator networks.
