Multi-µ: an Ada 95 Based Architecture for Fault Tolerance Support of Real-Time SystemsRef: HURRAY-TR-9812 Publication Date: 8, Nov, 1998
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.
