5.1. search for and use professional literature as well as any other sources of relevant information
5.2. remain informed of new developments and methods in physics, informatics, technology and education;
5.3. develop a personal sense of responsibility for their professional advancement and development

When a student successfully passes the course it will be able to:

1. Define main terms of teletraffic technology.
2. Describe the properties of transfer of information in various telecommunication networks, various access technologies, traffic measurement methods and routing methods as well as list telecommunication services, networks according different criteria, Internet access methods, QoS mechanisms.
3. Calculate traffic load, number of circuits, grade of service (blocking and waiting probability), QoS parameters (delay and waiting).
4. Apply appropriate model for solving the traffic problem in telecommunication networks (depending on the nature of the blocked calls: lost calls cleared or lost calls delayed) and solve the given problem.
5. Analyse the impact of traffic quantities on system performances (e.g. impact of different traffic load on user throughput performance).
6. Write seminar essay by compiling component ideas into a new whole.
