Overview
Telecommunications systems are complex real-world systems, containing many different components which interact, in complex interrelationships. The analysis of such systems can become extremely difficult: modelling techniques tend to analyse each component rather than the relationships between components. Simulation is an approach which can be used to model large, complex stochastic systems for forecasting or performance measurement purposes. It is the most common quantitative modelling technique used.
The selection of simulation as a modelling tool is usually because it is less restrictive. Other modelling techniques may impose material mathematical restrictions on the process, and also require multiple intrinsic assumptions to be made.
Network traffic simulation usually follows the following four steps:
- Modelling the system as a dynamic stochastic (i.e. random) process
- Generation of the realizations of this stochastic process
- Measurement of Simulation data
- Analysis of output data
