Scheduling mechanism of switched Ethernet for control network
Zude Zhou · Computer Engineering and Applications Journal · 2012
Considering the challenges in the application of the virtual-output-queue based input-queue switches to control network,a new switch structure is proposed in this paper.Accordingly,the switch structure based on the record matrix and demand matrix sequence control of the cell,which eliminates the uncertainty of cells'behavior and delay in switches,is designed.The characteristics of the traffic in control network are taken into account and a two-level scheduling mechanism is applied.The link scheduler provides the class of service while the switch scheduler is responsible for the match.
