<p><b>Abstract</b>—Information on <it>Fault Tolerance Latency</it> (FTL), which is defined as the total time required by all sequential steps taken to recover from an error, is important to the design and evaluation of fault-tolerant computers used in safety-critical real-time control systems with deadline information. In this paper, we evaluate FTL in terms of several random and deterministic variables accounting for fault behaviors and/or the capability and performance of error-handling mechanisms, while considering various fault tolerance mechanisms based on the trade-off between temporal and spatial redundancy, and use the evaluated FTL to check if an error-handling policy can meet the Control System Deadline (CSD) for a given real-time application.</p>
Fault tolerance latency (FTL), temporal/spatial and static/dynamic redundancy, error-handling, Control System Deadline (CSD), dynamic failure.
