| 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. |
| Learning Outcomes of the Course Unit |
|---|
| The subject Quality of services aims to introduce students to the issues of evaluation, definition, modeling and enforcement of quality parameters of multimedia services in networks based on the IP protocol implemented both using traditional technologies and software-defined networks. |
