Structural Failure Models for Fault-Tolerant Distributed Computing
Given that faults cannot be prevented in sufficiently complex systems, means of fault tolerance are essential for dependable distributed systems. Designing and evaluating fault-tolerant systems require well-conceived fault models. In the past, theoretical

Im Software Engineering wird traditionell ein Fokus auf den Prozess der Konstruktion von Softwaresystemen gelegt. Der Betrieb von Systemen, die kontinuierlich Dienste mit einer geforderten Qualität bieten müssen, stellt eine ebenso große Herausforderung dar. Ziel der Reihe Software Engineering Research ist es, innovative Techniken und Methoden für die Entwicklung und den Betrieb von nachhaltigen Softwaresystemen vor zustellen. Traditionally, software engineering focuses on the process of constructing and evolving software systems. The operation of systems that are expected to continuously provide services with required quality properties is another great challenge. It is the goal of the Series Software Engineering Research to present innovative techniques and methods for engineering and operating sustainable software systems.

Foreword
Despite means of fault prevention such as extensive testing or formal verification, errors inevitably occur during system operation. To avoid subsequent system failures, critical distributed systems, therefore, require engineering of means for fault tolerance. Achieving fault tolerance requires some redundancy, which, unfortunately, is bound to limitations. Appropriate fault models are needed to describe which types of faults and how many faults are tolerable in a certain context. Previous research on distributed systems has often introduced fault models that abstract too many relevant system properties such as dependent and propagating component failures. In this research work, Timo Warns introduces new structural failur
