Scenario-Driven Dynamic Analysis of Distributed Architectures

Abstract. Software architecture constitutes a promising approach to the development of large-scale distributed systems, but architecture description languages (ADLs) and their associated architectural analysis techniques suffer from several important shortcomings. This paper presents a novel approach that reconceptualizes ADLs within the model-driven engineering (MDE) paradigm to address their shortcomings. Our approach combines extensible modeling languages based on architectural constructs with a model interpreter framework that enables rapid implementation of customized dynamic analyses at the architectural level. Our approach is demonstrated in XTEAM, a suite of ADL extensions and model transformation engines targeted specifically for highly distributed, resource-constrained, and mobile computing environments. XTEAM model transformations generate system simulations that provide a dynamic, scenario- and risk-driven view of the executing system. This information allows an architect t...
