A taxonomy of software architecture-based reliability efforts

Abstract

Due to the complexity of the current software systems and the diversity of their architectural styles and component models, architecture-based reliability is becoming a more important quality requirement than ever before. Architecturebased reliability efforts depend on the behavior of individual components and their interactions with respect to their influences on the system reliability. Depending on different viewpoints and assumptions, a component takes various definitions and forms. As a result, numerous reliability works that involve varieties of the underlying strategies, objectives, and parameters are proposed for software architectures. Classifying these efforts is important for creating and selecting potential solutions that handle the reliability of software applications. In this paper, we provide a taxonomy of architecture-based reliability efforts. We classify these efforts according to the reliability goals, component abstraction, and level of granularity. We explain the existing techniques considering their assumptions with respect to these classification parameters and provide detailed description about the specific issues and considerations of each class.

Estimating Software System Reliability: An Architecture-Based Approach

“…However, their usage are limited because of not suitable for cyclic architectures due to infinite path [3]. Propagation-based models focus on error propagation among components which represent the possibility of dependencies of component failures [2]. This paper adopts state-based approach and employs DTMC to calculate the system reliability.…”

“…One of the main goals of architecture-based reliability efforts is estimating the system reliability by leveraging failure forecasting techniques [2]. The existing architecturebased models are mainly classified as state-based, path-based, propagation-based, and supplementary techniques.…”

“…The path-based models follow the possible execution paths of the architecture, but they are not suitable for cyclic architectures due to infinite path [3]. Propagation-based models focus on error propagation among components which represent the possibility of dependencies of component failures [2].…”

“…FTMs, which aims at failure avoidance, is carried out via error detection and system recovery [5]. It is likewise a main target of architecture-based reliability efforts which helps to build a more reliable software system [2]. Some existing research works [6] consider the effect of error propagation in component-based software systems.…”

Evaluating Software System Reliability Using Architecture Based Approach

“…Propagation-based models concentrate on slip proliferation around segments which representable the likelihood about dependencies from claiming part disappointments. [2].…”
