The aim of the course is to present an overlook of dimensioning of telecommunications networks on the basis of results of the queuing theory (QT). Introduce possibilities of simulation and modeling networks both from the point of view of grade of service GoS and quality ofservice QoS as well. Results of the QT are applied on different service systems and telecommunication networks deploying and operating at time being. Theoretical knowledge about models of service systems can be utilized for dimensioning of different service systems in real life - not only in the telecommunication.


The basic knowledge of the probability theory, stochastic processes and statistic are supposed.

Syllabus of lectures:

1. Service systems (SeSy), description and classification of SS.

2. Sources, input flow, service process, output flow. Poisson's flow, nature and character.

3. Mathematical description, influence type of flow on Gos and QoS. Kendall's classification.

4. Markov's type SeSy. Chapman-Kolmogorov's equations.

5. Loss SeSy - M/M/N/0 a M(n)/M/N/0.

6. Non-Markovian models G/M/N, M/G/N a G/G/N. Application.

7. Generalized Erlang's model, solution, application examples.

8. Waiting and loss SeSy - M/M/N/X/FIFO (RAND, LIFO).

9. Models M/M/N/R, specification, parameters GoS. Dimensioning.

10. Summary of the theory of loss and waiting SeSy, practical applications.

11. Quality of service (QoS, GoS, NP). Dependability, availability and reliability of item and network.

12. Priority SeSy, some specific results. Practical applications.

13. Models and methods of SeSy overload protection.

14. Simulation of SS - Monte Carlo methods. Numerical examples.
