Abstract

We present a technique for designing reconfiguration controllers in the Fractal component-based framework. We obtain discrete control loops that automatically enforce safety properties on the interactions between components, concerning, e.g., mutual exclusions, forbidden or imposed sequences. We use a reactive programming language, with a new mechanism of behavioural contracts. Its compilation involves discrete controller synthesis, which automatically generates the correct adaptation controllers. We apply our approach to the problem of adaptive ressource management, illustrated by the example of a HTTP server.
