The Network: Notes

The increasing requirements of extended functionality in vehicles has underpinned the development of systems with better performance and more functions. The MOST network is a result of this development.

The MOST network is a fiber optic network which allows a high number of different commands and messages to be sent and received on the same cable and in the same direction.

By using a fiber optic network, functionality is extended without increasing the amount of wiring.

The number of commands and messages which can be handled on the network depends on factors such as the network speed and the length of the message or command. The MOST network which is used in Volvo cars has the capacity to transmit over 300 message types and approximately 1000 messages per second. The transfer rate on the MOST network is approximately 25 Mbit/s.
