Qualité de service et ordonnancement dans les systèmes de communication temps réel

Abstract : In this thesis, we are interested in special real time communication systems called Fieldbus networks, i.e. without network nor transport layers. Most of these systems are designed to satisfy certain user time-related requirements, basically the periodic exchanges and sometimes the sporadic exchanges. Generally, the requirements are met and guaranteed by a static or off-line configuration of the message scheduling. We propose a dynamic solution in place of the static solutions. This solution takes as starting points the Quality of Service architecture defined in the wide-area networks and the Integrated service model of the Internet community which are generally used at the network layer. We propose then a dynamic resource reservation protocol which can be used by any MAC protocol of type centralized and for any topology. In addition, this protocol can accept various scheduling algorithms. It was specified in terms of state-transition systems and was validated using the ObjectGEODE tool.
