K. Tso, E. Shokri, "ReSoFT: A Reusable Software Fault Tolerance Testbed",
Pacific Rim International Symposium on Fault Tolerant Systems, Newport Beach, CA,
December, 1995
The need to experiment with software fault tolerance (SWFT) for investigating its
effectiveness and the desire toreduce effort in creating those experimental SWFT
systems have motivated the development of the Reusable Software Fault Tolerance
Testbed (ReSoFT). The testbed is built based on an open architecture and uses standard
off-the-shelf hardware and software, thus making it easily available and resilient
to technological changes. ReSoFT provides a library of reusable components for the
users to create systems utilizing a wide variety of SWFT techniques. In addition,
interface components that support the seamless integration of applications into
the SWFT systems, and fault-injection components that support dependability testing
and evaluation are also provided. The paper presents a SWFT reuse framework that
resulted from an analysis of the SWFT domain, the design of the SWFT reusable components
using the object-oriented method, and configuration of the testbed supporting the
creation, execution, and evaluation of the SWFT systems.
