4.1 Event Scheduling

The ns-3 event scheduling framework was designed with the following use-cases in mind:

• maximize code portability by ensuring reproducible time calculations in user models.
• make it possible to increase the precision of the internal time variable in the future.
• make it easy to associate a specific function to be called when a specific event expires
• make it easy to pass per-event data from the point when the event is scheduled to the point when the event expires
