Design and Performance Analysis of 10 Mbit/ s CAN 2009-01-0126

In this paper, we propose a new automotive network protocol which can transmit data at a speed of 10 Mbit/s. The new automotive protocol “10 Mbit/s CAN” is based on two changes to CAN; a star topology, in which nodes are physically connected using a multi-port gateway, and a new collision resolution algorithm which guarantees delivery of a message within a finite period of time. According to our analysis using a simulator, the “10 Mbit/s CAN” protocol demonstrated several advantages over throughput performance of a conventional CAN, including a maximum possible data transmission speed, high scalability, and reduction of priority inversion. The implementation considerations of “10 Mbit/s CAN” are also reviewed briefly.
