Editing Network traffic simulation (section)

==Advantages of simulation==

*Normal analytical techniques make use of extensive mathematical models which require assumptions and restrictions to be placed on the model. This can result in an avoidable inaccuracy in the output data. Simulations avoid placing restrictions on the system and also take random processes into account; in fact in some cases simulation is the only practical modelling technique applicable;<ref name="flood" /><ref name="penttinen" />
*Analysts can study the relationships between components in detail and can simulate the projected consequences of multiple design options before having to implement the outcome in the real-world.<ref name="flood" /><ref name="penttinen" />
*It is possible to easily compare alternative designs so as to select the optimal system.<ref name="flood" />
*The actual process of developing the simulation can itself provide valuable insights into the inner workings of the network which can in turn be used at a later stage.<ref name="flood" />
