Although it has been recognized as crucial, it has received relatively little attention. We present a policy refinement framework grounded in goal-elaboration methodologies and reactive systems analysis. Through linear-time model checking, we obtain system trace executions aimed at fulfilling lower-level goals refined with the KAOS goal-elaboration method. From system executions, we abstract managed entities, conditions and actions to encode the refined policies. We present our framework and provide a refinement scenario applied to the DiffServ QoS management domain.Javier Rubio-LoyolaJoan SerratParis FlegkasGeorge PavlouAlberto Lluch-Lafuentealberto.lluch@imtlucca.it
