Engineering fault tolerance

点击翻译按钮获取中文摘要

The scope and complexity of computer-based and controlled systems continue to increase dramatically. Modern software must satisfy an increasing number of requirements, provide real-time functionality, and has to interact with other software systems in a heterogeneous and changing environment. More and more responsibility of providing critical functionality is assumed by software, and hence the consequences of such systems behaving in an unpredictable way can be considerable. To successfully build such dependable "systems of systems", applications have to be engineered in such a way that they can provide service in spite of faults. They must be able to tolerate unexpected behavior of external entities in their environment, unreliable underlying components, communication failures, erroneous data and faulty algorithms.
