Unreliable failure detectors are a fundamental
building block in the design of reliable distributed systems.
But unreliability must be bounded, despite the uncertainties
affecting the timeliness of communication. This is why it is
important to reason in terms of the quality of service (QoS) of
failure detectors, both in their specification and evaluation.
We propose a novel dependability-oriented approach for
specifying the QoS of failure detectors, and introduce Adaptare-
FD, an autonomous and adaptive failure detector that executes
according to this new specification. The main distinguishing
features of Adaptare-FD with respect to existing adaptive failure
detection approaches are discussed and explained in detail.
A comparative evaluation of Adaptare-FD is presented. We
highlight the practical differences between our approach and
the well known Chen et al. approach for the specification
of QoS requirements. We show that Adaptare-FD is easily
configured, independently of the specific network environment.
Furthermore, the results obtained using the PlanetLab platform
indicate that Adaptare-FD outperforms other timeout-based
solutions, combining versatility with improved QoS and
dependability assurance.
