ReSoFT: A Reusable Testbed for Development and Evaluation of Software Fault-Tolerant Systems

The Reusable Software Fault Tolerance Testbed ReSoFT was developed to facilitate the development and evaluation of high-assurance systems that require tolerance of both hardware and software faults. Central to ReSoFT is a library of reusable software components for the construction of target systems that utilize a wide variety of software fault tolerance SWFT techniques. The reusable components include 1 SWFT Executive components, 2 SWFT Support components, 3 Application Interface components, 4 Fault-injection components, and 5 Communications components. A set of graphical tools are also provided for users to build, monitor, and test the SWFT systems. The ReSoFT testbed was developed on a network of Sun workstations running the Solaris operating systems. The workstations are connected with dual-redundant networks. Object-oriented analysis and design based on the Booch Method had been used to develop the reusable components. The components are implemented in Ada 95 to take adv...
