Abstract

Unreliable failure detectors have been an important abstraction to build dependable communication applications over iSCSI systems subject to faults. In this paper, we propose a new implementation of a failure detector. This implementation is a variant of the heartbeat failure detector which is adaptable and can support scalable applications. In this implementation we dissociate two aspects: a basic estimation of the expected arrival date to provide a short detection time, and an adaptation of the quality of service according to application needs.
