Apparatus for configuring and validating an intervention in a real-time ethernet data network

An apparatus for configuring and validating an intervention in a real-time Ethernet data network having ECUs in a motor vehicle, the apparatus comprising:

• a vehicle diagnostic device, which is configured to receive configuration change data and to transfer said configuration change data to a first data storage device;
• the first data storage device, which is configured to receive and store the configuration change data from the vehicle diagnostic device;
• a first data checking device, which is configured to check the configuration change data stored in the first data storage device by using a first integrity check and to transfer said configuration change data to a second data storage device in the event of a positive first integrity check;
• the second data storage device, which is configured to receive and store the configuration change data from the first data checking device;
• a second data checking device, which is configured to check the configuration change data stored in the second data storage device by using a second integrity check and to enable said configuration change data for the real-time Ethernet data network in the event of a positive second integrity check taking into consideration the overall affected network state, wherein the second integrity check involves checking whether and which effects the configuration on the network, this comprising a check on the ECUs for the configured configuration and a check on the associated communication relationship;
• and
• a configuration master device, which is configured to receive the enabled configuration change data from the second data storage device and to transmit said configuration change data to a switch and/or a component of the real-time Ethernet data network in order to renew at least some of an Ethernet TSN configuration in the ECUs and switches.
