Learning Outcomes

  1. Understand and explain basic metrics for network performance
  2. Understand and explain the basics of queuing theory
  3. Know how to apply queuing theory in network analysis and modeling
  4. Understand and explain Markov processes
  5. Be able to apply knowledge of Markov processes in network analysis and modeling

Forms of Teaching

Lectures

Theoretical lectures with teaching practical tools as well

Independent assignments

Homework in which it is necessary to make a practical part and write a report

Laboratory

Group project

Other

The course is taught through lectures, homework, and laboratory exercises. Lectures are three hours per week. For each lecture, students should prepare and read the assigned literature that is discussed during the first hour. During the class the tasks are also solved. Students are tasked to do a practical part presented in a lecture within four homework assignments. Furthermore, students have a group project. In a group project, they should apply the theoretical knowledge gained in the lecture. In this approach, theoretical knowledge should be applied twice, first in the course of homework (structured application) and second in the project (free application).
