Foil 65 Execution Model for Event processing

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 97. by Zeynep Ozdemir(Geoffrey C. Fox)
1 Once a sensor or Script has generated an initial event, the event is propagated from the eventOut producing the event along any ROUTEs to other nodes.
  • These other nodes may respond by generating additional events, continuing until all routes have been honored. This process is called an event cascade.
  • All events generated during a given event cascade are assigned the same timestamp as the initial event, since all are considered to happen instantaneously.
2 Some sensors generate multiple events simultaneously. In these cases, each event generated initiates a different event cascade with identical timestamps.
