Abstract
The aim of the paper is to summerize some of the methods for modeling of overall telecommunication systems developed by the authors at the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences and to propose new methods using the apparatus of the Generalized Nets (GNs) theory. On the basis of the discussed methods, two basic tasks about overall telecommunication systems are formulated. Analytical models for solving the Quality of Service (QoS) prediction task and the Network Dimensioning/Redimensioning Task (NDT/NRDT) are proposed. A classical model of overall telecommunication system is considered. General teletraffic tasks are formulated on the basis of a proposed conceptual model. Some assumptions for the system are stated which allow for a relatively simple analytical model to be obtained. Analytical expressions for basic teletraffic characteristics of the main tasks about overall telecommunication systems are derived. Graphical representation of the results is included. A comparison with other approaches for network dimensioning is made and is represented graphically
