In recent years, the focus of software development has progressively shifted upward, in the direction of the abstract level of architecture specification. However, while the functional properties of the systems have been extensively dealt with in the literature, relatively less attention has been given until recently to the specification and analysis at the architectural level of quality attributes such as performance and reliability. The contribution of this paper is twofold: first we discuss the type of information that should be provided at the architectural level in order to successfully address the problem of performance and reliability modeling and analysis of software systems; based on this discussion, we define an extension of the xADL architectural language that enables the support for stochastic modeling and analysis of performance and reliability in software architectures.
