This course provides the theory that lies behind bandwidth management, traffic shaping and QoS, as well as their implementation on Linux – and practical exercises and workshops that allow the participants to put the theory into practice and learn how to use it successfully.
During the workshop part of the course, the participants do, among others, configure computers capable of fulfilling the router function.
