Lectures are intended to support the instructor’s presentation of fundamental issues. Students should, preferably before classes, study the recommended bibliography.
Laboratory sessions take place in a specialized laboratory and their aim is to perform several network configurations and test their performance. The laboratory is equipped with state of the art network gear, identical to the one currently used in industry in small to medium networks. These lab sessions are based on a “hands-on” computer network learning approach.
Some laboratory classes use emulators and other software tools.
Group projects allow students to gain insights in hot and emergent computer networking topics.
Two intermediate tests (2 x 20%). Two article summaries (2 x 5%). Two laboratory assignments (2x25%).
It is required: tests average ≥ 8, articles average ≥ 8 and labs average ≥ 8. If the exam replaces the tests''s marks, then exam ≥ 8.
"Frequência" is mandatory and requires obtaining lab assignements''s average grading ≥ 8.
Late delivery of essays, reports or lab assignments imply a penalty of one mark per day up to a maximum of 5 days.
Tests are closed-book ones but students can use an A4 sheet with their study notes.
All intermediate grades have a resolution of 0.1 mark.
- Flooding, Spanning tress, VLANs
- Shortest-path routing and link state protocols
- Networks principles, models and tools
- IP addressing
- Congestion control at the edge and at the network level
- Quality of service tools
- Tunnels utilization and a short introduction to MPLS
- Data centre application requirements and traffic patterns
