Dimensioning of Telecommunication Networks

The course is a substitute for:

Dimensioning of Telecommunication Networks (X32DTS)

Lecturer:

Tutor:

Supervisor:

Department of Telecommunications Engineering

Synopsis:

The course utilize knowledge offered in the course X32THO which are applied to dimensioning of service systems of different types, especially the type M/M/N/R,..,X/M/N/0,... and networks. Special attention is devoted to dimensioning of networks with traffic oveflow and in this connection to the process of optimization of structure of network. At the end of the course a special attention is devoted to the traffic simulation of service systems and networks.

Requirements:

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

For awarding of assessment student must fulfilled following requirements:

1) Students must to go through all of given practical exercises

Students have to pass successfully project

Syllabus of lectures:

The necessary assumption for study in the course is to pass through the 32THO course.

2. Evaluation of Quality of Service GOS, Network Performance NP of TN and Grade of Service GOS

3. Graphs a matrices description of- TN topology and its utilisation in process optimisation

4. Topology optimisation. Algorithms (Prime, Kruskal, Dijkstra), Rapp's method

5. Description of information flows (regenerative, recurrent and ordinary flow, Poisson's flow). Traffic flows in TN.

6. Routing in TN classification (Dijkstra's and Ford-Fulkerson's algorithms). Traffic overflow, principles of application

7. Basis of application traffic and queuing theory in TN. Models of service systems (SS) in TN
