Comparing Operating Systems Using Robustness Benchmarks
Any type of content formally published in an academic journal, usually following a peer-review process.
When creating mission-critical distributed systems using off-the-shelf components, it is important to assess the dependability of not only the hardware, but the software as well. This paper proposes a way to test operating system dependability. The concept of response regions is presented as a way to visualize erroneous system behavior and gain insight into failure mechanisms. A5-point “CRASH” scale is defined for grading the severity of robustness vulnerabilities encountered. Test results from five operating systems are analyzed for robustness vulnerabilities, and exhibit a range of dependability. Robustness benchmarking comparisons of this type may provide important information to both users and designers of off-the-shelf software for dependable systems.
