“…Este valoré passadoà uma função para a estimação do novo intervalo de timeout Δ to a ser considerado para o detector. A função de estimaçãoé descrita em [6]. Esta adaptação permite que o intervalo de timeout Δ to seja aproximado do intervalo entre o envio de mensagens heartbeat Δ i conforme R se mantém constante.…”

Fault detection is core functionality required by most fault tolerance strategies, but it often depends on reliable communication between computing nodes exchanging monitoring information. We present techniques to improve the robustness of fault detectors for distributed platforms in situations where network connectivity is affected by packet loss and delays. Similar network conditions can be found in computing grids connecting geographically distant resources. We present results from experimental tests conducted in a simulated environment. The results show significant improvement over traditional approaches. Detecção distribuída de falhasDetectores distribuídos de falhas, em sua definição mais pura, são módulos de detecção que monitoram um subconjunto de processos no sistema, mantendo uma lista dos processos atualmente suspeitos de terem falhado [2]. Estes detectores de falhas são considerados não confiáveis pois podem cometer enganos ao passar a suspeitar de um processo 2012 13th Symposium on Computing Systems 978-0-7695-4847-0/12 $26.00
