    Abstract: Failure detectors are fundamental components of large-scale distributed systems. A failure detector must perceive node crashes promptly adapting to changing network conditions. In addition, it has to be accurate and avoid wrong suspicions, since the latter result in unnecessary processing. Moreover, failure detectors should, ideally, have modest requirements in terms of memory consumption and processing time. This paper presents an accrual and fuzzy failure detector (ACD). The ACD employs ideas from Fuzzy Logic and outputs a suspicion level on a continuous scale. Furthermore, the ACD requires less resources than other detectors.
