Controller Area Network (CAN) and Ethernet both use Carrier Sense Multiple Access with Collision Detection (CSMA/CD) as a media access control method. Beyond that, the CAN protocol is based on CSMA/ CD/AMP (Carrier-Sense Multiple Access/Collision Detection with Arbitration on Message Priority) protocol. Due to CSMA/CD in Ethernet as soon as the collision is detected data transmission is terminated, a jam signal is sent and then before trying to resend the frame waits for a random time interval. CAN protocol; however, solves the collision problem using the principle of arbitration, where only the highest priority node is given the right to send its data.
