Controller area network (CAN) and other existing technologies like LIN, Flexray, MOST were used as system buses in the automotive field earlier days. But these standards are now outdated in terms of payload, speed, etc. The move to Automotive Ethernet provides higher-quality, lower latency, time synchronization of audio and video in Ethernet standard format to transmit realtime audio and video streams. Automotive ethernet is a key driver of change in the electrical and electronics (E/E) structure of a car. Automotive Ethernet has switched networks with a point to point communication.
