Network Protocol Design (ITC8061, 6 ECTS)

This module focuses on fundamental problems of network protocols and various design decisions and it's implications. This will also include security related protocols and give a better understanding why it is sometimes so hard to secure the Internet. As an exercise we will develop and implement our own protocol.

This module requires some programming skills (or a LOT of motivation to spend a LOT of time on learning algorithms and programming languages on top of the network-protocol related challenges). See also here for more detailed information.

The lectures and seminar discussions will Wednesday, 12.00 - 13.30. We will use distance learning MS-Teams channel due to the pandemic situation.
