Abstract
This paper describes experiences with an implementation of
the X25 long haul data communications protocol based on Demos, a Simula
extension with enhanced discrete event capabilities. X25 has a modern
definition with functionally separated layers which are mapped
directly into a hierarchy of Simula (Demos) packages. During development
and testing, the X25 processes were embedded in a simulation model of
the real time environment, and subjected to extensive testing before
acceptance. The design steps are repeated should further enhancements
be required, or design errors be revealed after commissioning.
