Abstract
Abstract-This paper describes the Multicomputer Architecture for Fault-Tolerance (MAFT), a distributed system designed to provide extremely reliable computation in real-time control systems. MAFT is based on the physical and functional partitioning of executive functions from application functions. The implementation of the executive functions in a special-purpose hardware processor allows the fault-tolerance functions to be transparent to the application programs and minimizes overhead. Byzantine Agreement and Approximate Agreement algorithms are employed for critical system parameters. MAFT supports the use of multiversion hardware and software to tolerate built-in or generic faults. Graceful degradation and restoration of the application workload is permitted in response to the exclusion and readmission of nodes, respectively. Index Terms-Approximate agreement, distributed systems, fault tolerance, flight control, interactive consistency, real-time systems. I.
