Dynamic reconfiguration increases the availability of distributed applications by allowing them to evolve at run-time. This paper deals with the formal specification and model-checking verification of a dynamic reconfiguration protocol used in industrial agent-based applications. Starting from a reference implementation in Java, we produced a specification of the protocol using the Formal Description Technique LOTOS. We also specified a set of temporal logic formulas characterizing the correct behaviour of each protocol primitive. Finally, we studied various finite state configurations of the protocol, on which we verified these requirements using the CADP protocol engineering tool set.
