To achieve fast link failure detection in all-optical networks, the notion of monitoring-cycle (m-cycle) is introduced. The best known m-cycle construction algorithm (HST [7]) adopts a spanning tree-based approach. In this paper, we propose a new algorithm M-CYCLE to construct a set of minimum-length mcycles (or m-cycles) for more efficient link failure detection. We prove that the performance ...
Failure detection has always been a demanding task in the electrical machines community; it has become more challenging in wind energy conversion systems because sustainability and viability of wind farms are highly dependent on the reduction of the operational and maintenance costs. Indeed the most efficient way of reducing these costs would be to continuously monitor the condition of these sy...
A group membership failure (in short, a group failure) occurs when one of the group members crashes. A group failure detection protocol has to inform all the non-crashed members of the group that this group entity has crashed. Ideally, such a protocol should be live (if a process crashes, then the group failure has to be detected) and safe (if a group failure is claimed, then at least one proce...
Al~traet--All failure detection methods are based, either explicitly or implicitly, on the use of redundancy, i.e. on (possibly dynamic) relations among the measured variables. The robustness of the failure detection process consequently depends to a great degree on the reliability of the redundancy relations, which in turn is affected by the inevitable presence of model uncertainties. In this ...
Debate persists about monitoring method (culture or smear) and interval (monthly or less frequently) during treatment for multidrug-resistant tuberculosis (MDR-TB). We analysed existing data and estimated the effect of monitoring strategies on timing of failure detection.We identified studies reporting microbiological response to MDR-TB treatment and solicited individual patient data from autho...
Failure detection is a fundamental building block for ensuring fault tolerance in large scale distributed systems. There are lots of approaches and implementations in failure detectors. Providing flexible failure detection in off-the-shelf distributed systems is difficult. In this paper we present an innovative solution to this problem. Our approach is based on adaptive, decentralized failure d...
