Abstract

Many atomic broadcast algorithms have been published in the last twenty years.Token-based algorithms represent a large class of these algorithms.Interestingly, all the token-based atomic broadcast algorithms rely on a group membership service, i.e., none of them uses unreliable failure detectors directly.The paper presents the first token-based atomic broadcast algorithm that uses an unreliable failure detector - the new failure detector denoted by R - instead of a group membership service.The failure detector R is compared with 驴P and 驴S.In order to make it easier to understand the atomic broadcast algorithm, the paper derives the atomic broadcast algorithm from a token-based consensus algorithm that also uses the failure detector R.
