Abstract :
Real-time local area networks like Fieldbus have to handle two types of data transfer, synchronous and asynchronous. Synchronous data are generated periodically and have to be transmitted before fixed deadlines. Asynchronous messages are generated by unforeseen events and thus cannot be predicted. The data transfer is handled in two different phases. In this paper the authors study the properties of some scheduling algorithms to see how best the asynchronous messages are scheduled so that they meet their deadlines
