In this example, we assume an event-driven architecture where asynchronous messages, or notifications, are exchanged among the components of the system by means of a message or notification broker.

You can add Message Broker to a system that uses TCP/IP for transport in order to generate a more flexible architecture for communication between the components, as shown in the diagram below.

Finally, the simulation design of an example of DRES: "driving control and monitoring system of car" reveals the effectiveness and merits of message architecture model and time-accounting measure.
