An XML-Based Language to Support Performance and Reliability Modeling and Analysis in Software Architectures

Abstract

Abstract. 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.

Optimizing decomposition of software architecture for local recovery

“…4. The concept of analytical interface has been borrowed from (Grassi et al 2005), where Grassi et al define an extension to the xADL language to be able to specify parameters for performance analysis. They introduce a new type of interface that comprises two types of parameters: constructive parameter and analytic parameter.…”

Guiding Architects in Selecting Architectural Evolution Alternatives

“…In order to capture these quality attributes in architectural changes and models, we have extended the existing xADL schema with new types; namely reliability interface and cost component. The concept of an interface with analytical parameters has been borrowed from [10]. The reliability interface is added to components/connectors and it consists of a reliability value R, where 0 < R < 1.…”

Architecting fault-tolerant software systems

“…A part of the corresponding XML schema that introduces the new properties is shown in Figure 5.7. The concept of an interface with analytical parameters has been borrowed from [49], where Grassi et al define an extension to the xADL language to be able to specify parameters for performance analysis. They introduce a new type of interface that comprises two type of parameters; constructive parameter and analytic parameter.…”
