Summary
The course introduces students to the principles and methods for evaluating, determining and modeling quality parameters in IP networks, both from the point of view of the network (QoS) and from the point of view of the end user (QoE). Students verify the acquired knowledge using software models of traditional and software-defined networks.
Compulsory literature:
Recommended literature:
Way of continuous check of knowledge in the course of semester
Five scored tasks from the discussed issue
Individual tasks (40 points in total), each for 8 points:
1/ Simulation of network traffic, scored task, T4
2/ Determining the MOS of a call in a mobile network, scored task, T6
3/ Evaluation of video quality, scored task, T8
4/ Basic tasks in SDN with the Mininet tool, scored task, T10
5/ SDN controller, advanced SDN simulations, scored task, T12
Knowledge is verified by a test in the exam.
