Abstract :
This paper investigates the fault-containment and error-detection mechanisms of distributed safety-critical time-triggered systems. The following critical failure modes of a fault-containment region are introduced and analyzed in detail: babbling idiot failures, masquerading failures, slightly-off-specification (SOS) failures, crash/omission (CO) failures, and massive transient disturbances. After a short description of the two time-triggered protocols TTP/C and FlexRay this paper tries to show how these two protocols handle the listed failure modes at the architecture level.
