Unreliable failure detectors have been an importantabstraction to build dependable distributed applicationsover asynchronous distributed systems subject to faults.Their implementations are commonly based on timeoutsto ensure algorithm termination. However, for systemsbuilt on the Internet, it is hard to estimate this time valuedue to traffic variations. Thus, different types ofpredictors have been used to model this behavior andmake predictions of delays. In order to increase thequality of service (QoS), self-tuned failure detectorsdynamically adapt their timeouts to the communicationdelay behavior added of a safety margin. In this paper,we evaluate the QoS of a failure detector for differentcombinations of communication delay predictors andsafety margins. As the results show, to improve the QoS,one must consider the relation between the pairpredictor/margin, instead of each one separately.Furthermore, performance and accuracy requirementsshould be considered for a suitable relationship.
