Computer Networks

The course focuses on computer networking and communication technologies as a continuation of TTM4175 Communication Technology, Introduction. The covered topics include core reference models, services and protocols used in computer networks, including aspects from the physical layer to the application layer. Practical networking aspects are also addressed, namely by deploying, managing and using services and protocols widely used in the Internet (e.g. SSH, SMTP, DNS, HTTPS, among others). Fundamentals of network and communication security are introduced in the context of the other topics.

A. Knowledge: To have a basic understanding of and to be able to recognise:

1. the fundamental concepts and principles of OSI and TCP/IP layers;
2. the Ethernet communication technology;
3. architectures, switching and routing principles used in computer networks;
4. networking tools, protocols and services used in computer networks and in Internet services such as DNS, web and email;
5. networking security principles, tools and protocols used in computer networks.

B. Skills: To be able to:

1. apply switching and routing in IPv4/IPv6 networks;
2. set up a simple IPv4/IPv6 network with support for services such as DNS, web and email;
3. use basic networking tools, protocols and services required to manage a computer network;
4. apply fundamental networking security principles, tools and protocols used in computer networks;
5. create basic network applications.

C. General competence: To be able to use the acquired knowledge and skills for:

1. responsibly and ethically applying basic communication and computer networking principles in a societal context;
2. collaborating to the development of computer networks, both independently and in teams.

The course teaches the fundamental knowledge, skills and competences behind digital communications and the Internet. For that reason, it indirectly contributes to all UN Sustainable Development Goals (SDGs) where digital solutions can benefit from ubiquitous access to a communication platform.

The course uses team-based learning. Lectures and exercises are combined. The intention is to facilitate learning and to provide feedback to students throughout the semester, and enable learning in the context of realistic scenarios through projects.

Throughout the semester, students receive feedback on their level of preparation through Readiness Assurance Tests (RATs), which are multiple-choice tests that are done during class time. Each test introduces the students to a new subset of concepts.

To develop skills and knowledge on higher cognitive levels, students also conduct practical assignments in teams throughout the semester and receive feedback in various ways, including feedback by peers, teaching assistants and the teacher.

Attendance to the lab sessions is compulsory.
