An architectural pattern for non-functional dependability requirements

We address the research question of transforming dependability requirements into corresponding software architecture constructs, by proposing first that dependability needs can be classified into three types of requirements and second, an architectural pattern that allows requirements engineers and architects to map the three types of dependability requirements into three corresponding types of architectural components. The proposed pattern is general enough to work with existing requirements techniques and existing software architectural styles, including enterprise and product-line architectures.
