In the following text, we will give you an example of communication for the following scenario : Suppose that Event Service has created an event with identification number 12, and that the event was broadcasted to all vehicles. Some time later, system needs to get an estimation of the time it takes vehicle with identification number 43 to get to event's location. It is obvious from earlier text, that there exists Vehicle Proxy on the server (also with identification number 43) that is responsible for communicating with this vehicle. Physical address of the vehicle is "VehicleAddress" and physical address of the computer that runs the core is "ServerAddress".

First, Vehicle Proxy is sending a message with type "estimation request" which contains only the identification number of the event. That number will be sufficient for the vehicle to estimate the time, because it received a broadcast message containing information about the event earlier.
