Abstract :
To overcome the drawback that switched Ethernet does not guarantee the timely delivery of real-time messages in industrial communication, an improved FTT (flexible time-triggered communication) paradigm was proposed for hard real-time communications of periodic messages on switched Ethernet. In addition, an optimization condition for feasibility check of periodic messages was given. Particularly, we proposed an EDF-based algorithm to schedule periodic messages to be transmitted within their deadlines over COTS switched Ethernet running in the cut-through mode. Simulation results showed the advantages of the proposed real-time scheduling algorithm in terms of using the aggregated switch throughput.
