On the Evaluation of Failure Detectors Performance
Résumé
Despite the great number of papers that broach the consensus agreement, just a few specifically discuss the structure or the implementation of failure detectors. Even these papers usually present only the structure of the detectors, and avoid presenting a comparison between the suggested detector and other existing ones. In fact, at the literature, we have found only one work that compares by simulations different failure detector models. We have chosen to use that paper as basis, and decided to make a comparison among some failure detectors models, using practical systems. In a practical environment, the implementation issues and the operational system can influence both the performance of the detectors and the consensus termination time. This paper presents our results, which allows us not only to judge the efficiency of these models, but also allow us to learn how these detectors work under different failure situations and under diverse system loads.
