Model-Driven Engineering (MDE) is a relevant approach to support the engineering of distributed embedded systems with performance and dependability constraints. MDE involves models definitions and transformations to cover most of the system life-cycle: design; implementation and Verification & Validation activities towards system qualification. Still; few works evaluate the early integration of performance evaluation based on architectural models. In this paper; we investigate the early-stage use of analysis in AADL modeling. Precisely; we exemplify on an avionics case study how to dimension the data flows for an application distributed over an AFDX network. Based on the insight from this study; we suggest a simple framework and associated techniques to efficiently support analysis activities in the early-stage design phases.
