Abstract (EN): In this paper, we present some of the fault tolerance management mechanisntv being implemented in the Multi-/z architecture, namely ira support for replica non-determinism. In thia architecture, fault tolerance is achieved by node active replication, with software based replica management and fault tolerance transparent algorithms. A software layer implemented between the application and the real-time kernel, the Fault Tolerance Manager (FTManager), is the responsible for the transparent incorporation of the fault tolerance mechanisms The active replication model can be implemented either imposing replica determinism or keeping replica consistency at critical points, by means of interactive agreement mechanisms. One of the Multi-I~ architecture goals is to identify such critical points, relieving the underlying system from performing the interactive agreement in every Ada dispatching point. © ACM 1999.
