Fault-tolerant telecommunication system patterns

The authors describe a dependability evaluation method based on fault injection that establishes the link between the experimental evaluation of the fault tolerance process and the fault occurrence process. The main characteristics of a fault injection ...

A fault-tolerant systolic sorter design is proposed. An algorithm-based fault tolerance is achieved by testing the invariants of a systolic sorter during normal operation. Transient and permanent computation errors can be detected by using error-...

The paper puts forward the idea of using fault tolerance refinement patterns to assist system developers in disciplined application of software fault tolerance mechanisms in rigorous system design. Two patterns are proposed to support a correct ...
