| Summary: | Fault injection has long been recognized as a valuable approach for validating fault tolerance. This dissertation presents a reference framework for developing a software- based fault-injection tool. By modeling the behavior of a software system as a predicate graph, the framework embodies a method for evaluating the results obtained using such a tool. A software object-oriented fault-injection tool (SOFIT) that has been developed, based on the proposed framework, is described. Another objective of this dissertation is to present a software-implemented approach for improving the dependability characteristics of a software system. This approach provides a high level of user- transparency by employing object-oriented paradigms of data- encapsulation and polymorphisn-LA multi-stage design approach is presented to reduce the design and implementation faults in fault-tolerant software. Finally, a software-based approach is presented for creating fault-tolerant software for parallel-processing applications in a cost-effective way. |
