Feasibility analysis of fault-tolerant real-time task sets
Alan Burns, Robert Ian Davis, Sasikumar Punnekkat · 2002
Many safety critical real-time systems, employ fault tolerant strategies in order to provide predictable performance in the presence of failures. One technique commonly employed is time redundancy using retry/re-execution of tasks. This can in turn affect the correctness of the system by causing deadlines to be missed. This paper provides exact schedulability tests for fault tolerant task sets under specified failure hypothesis.
