Abstract
The real-time network simulation requires dealing with miscellaneous
technical problems to achieve a correct and timely execution. The
ignorance
of those issues can render a valid model useless, because its
implementation
would produce erroneous results. This paper identifies and
discusses the problems specific for a Linux operating system on the x86
architecture.
A problem of accurate event scheduling in a simulation process
without disturbing other processes is the most important and is considered
in detail. Several solutions to this problem are evaluated by
measurements.
The results show that no single solution fits all criteria, but the most
appropriate
method can be selected according to goals of a simulation study.
