Tags:xml.sequenceOffset=40 Table 3.34: SporadicEventTriggering This is a generalization of the periodic event triggering described in subsection 3.6.1.1. The difference is that the event can, but not necessarily shall occur. For this reason, there is one additional parameter required for the specification of the SporadicEventTriggering, namely the maximumInterArrivalTime, which specifies the largest possible time distance between two event occurrences. The Sporadic Event T riggering is characterized by the following parameters: • Minimum Inter-Arrival Time
