Avaliação Prática do Desempenho dos Detectores de Defeitos

Luiz Angelo Barchet-Estefanel

Despite the great number of papers which 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, avoiding to present a comparison between the suggested detector and other existing ones. Actually, to our best knowledge, there is only one work that compares different failure detector models. We have chosen to use that paper as basis, and decided to make a comparison using practical systems, where the implementation issues and the operational system could influence both the performance of the detectors and the consensus termination time. This paper presents the preliminary results from our work, that allow us to determine which one is the most efficient, but specially allow us to learn how these detectors work under different failure situations and under diverse system loads.
