Assessment of multi-bus fault-tolerant communications

Abstract

The flexible time-triggered CAN protocol supports synchronous and asynchronous traffic over a CAN fieldbus. The use of bus and master redundancy is an evolution to the original FTT definition. A protocol supporting multiple buses and masters has been proposed. This paper presents experimental results allowing to assess the timeliness of the communication system. The conclusion is that the system reacts according to its theoretical formalization in a consistent way.
