Fault Tolerance Techniques
Integrated Recovery Policies for Real-Time Systems was a three-year ongoing project, funded by DARPA, and conducted at the University of Massachusetts in Amherst. The goal was to design adaptive techniques for managing failure recovery in real-time embedded systems. Main areas where work was done include:
Development of dynamic recovery management policies
Development of fault-tolerant task scheduling algorithms
Development of a software testbed on which to study the performance of real-time scheduling algorithms and recovery policies
Using our the adaptive techniques we have developed as a part of this project have been shown to increase system dependability, or conversely reduce the hardware required to achieve a fixed level of dependability.
