Implementing a rule-driven approach for architectural self configuration in collaborative activities using a graph rewriting formalism

8 pagesInternational audienceArchitectural adaptation is important for handling self- con- figuring properties of autonomic distributed systems. It can be achieved by model-based management of dynamic archi- tectures. Describing dynamic architectures includes defin- ing rules for reconfiguration management. Within this re- search context, several works have been conducted using formal specification to handle this complexity. Graph and graph rewriting-based approaches showed, through many studies, their appropriateness to tackle architectural adap- tation problems. However, scalability of such approaches remains an open issue and has been rarely explored. In this paper, we investigate this issue. We introduce a graph-based general approach for handling of dynamic architectures, and we illustrate it within a scenario of collaboration support in Crisis Management Systems. We elaborate the formal mod- els for dynamic architecture management. Using the French Grid GRID5000, we conducted an experimental study to assess the scalability of the elaborated models
