Both industrial and automotive
networks need to be concerned about
• Safety
• Traffic determent/time synchronization
awareness
• Security
What is different is the scale: a large-scale plant compared to a car
• Small resourced constrained devices
Industrial vs. Automotive Networks

Future Considerations Enabled by the Ethernet
▪ Disturbed control and load sharing
— Zonal architecture
moving away from
traditional domain-
control architecture
▪ Fail operational
— Seamless
communication
between zonal nodes
opens up possibilities
