Ethernet is going mainstream, but CAN and other networks still will be needed as software and electronics do more.

Ethernet is displacing CAN (controller area networks) as the primary architecture for automotive networks, but a host of other communications protocols are helping reduce cost and complexity. Multiple consumer networks are being used to carry input from sensors and other devices to Ethernet backbones that transfer huge volumes of data to centralized controllers.

The ubiquitous network used in homes and businesses brings speed and low cost along with integration in both microchips and design tools. That's making it the mainstay in emerging vehicle architectures.
