DCEP-Sim facilitates simulation of distributed CEP where the latency and bandwidth limitations in the network are well reflected, but it currently lacks models to simulate the temporal behavior of event processing. In this demonstration, we use a modeling methodology to model the software execution of a CEP system called T-Rex. We instrument and trace T-Rex to parameterize a software execution model that is integrated into DCEP-Sim. Furthermore, we use this instance of DCEP-Sim to run simulations and see how significant the processing delay introduced by the model is compared to the transmission delay.
