A Fault-Tolerant Token-Based Atomic Broadcast Algorithm

André Schiper, Nils Richard Ekwall

Many atomic broadcast algorithms have been published in the last 20 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 and none of the ...

Modeling and validating the performance of atomic broadcast algorithms in high-latency networks

André Schiper, Nils Richard Ekwall

The performance of consensus and atomic broadcast algorithms using failure detectors is often affected by a trade-off between the number of communication steps and the number of messages needed to reach a decision. In this paper, we model the performance o ...

On the Cost of Modularity in Atomic Broadcast

André Schiper, Sergio Mena, Nils Richard Ekwall, Olivier Rütti

Modularity is a desirable property of complex software systems, since it simplifies code reuse, verification, maintenance, etc. However, the use of loosely coupled modules introduces a performance overhead. This overhead is often considered negligible, but ...
