Fieldbuses and Real-Time MAC Protocols
Résumé
An analysis of the Fieldbuses and MAC protocols is presented in this paper. The analysis takes into account both the temporal requirements of the applications and the characteristics of the services provided by the communication system in order to fulfill requirements such as periodicity, jitter, transfer delay, temporal coherence and spatial coherence. These characteristics are then analyzed as possible solutions leading to integration of a more general concept of Quality of Service in Fieldbuses and MAC protocols.
