Resumo(s)
This paper presents an architecture (Multi-μ) being implemented to study and develop
software based fault tolerant mechanisms for Real-Time Systems, using the Ada language
(Ada 95) and Commercial Off-The-Shelf (COTS) components. Several issues regarding fault
tolerance are presented and mechanisms to achieve fault tolerance by software active
replication in Ada 95 are discussed. The Multi-μ architecture, based on a specifically
proposed Fault Tolerance Manager (FTManager), is then described. Finally, some
considerations are made about the work being done and essential future developments.
