Research of Hybrid Scheduling Based on Network Calculus in Coal Mine Ethernet

Abstract:

According to the characteristics of data in coalmine industrial Ethernet ring networks and in order to guarantee the demand of the real-time data in it, a hybrid scheduling method with non-preemptive priority and EDF scheduling method based on the IEEE802.1p protocol is proposed in the switch. We calculate the maximum transmitting delay of the real-time data using network calculus theory. The result shows that EDF decreases transmission delay for non-periodic data better than FCFS by theoretical computation and simulation.
