Abstract
A scheduling method applied in an industrial heterogeneous network in which a TSN and a non-TSN are interconnected is provided. The TSSDN controller classifies data flows according to the delay requirements, and calculates the scheduling priorities of the data flows in the industrial heterogeneous network. The TSSDN controller adopts an improved CSPF algorithm to determine a shortest path in the heterogeneous network, and marks the scheduling priorities of the data flows which are transmitted from the subnet of the heterogeneous network and arrive at the switch for the first time. Flow table matching is performed at the SDN switch. In a case of performing flow table matching successfully, the counter is updated and the instruction included in the flow table is executed. In a case of performing flow table matching unsuccessfully, a PacketIn message is transmitted to the TSSDN controller, and the TSSDN controller performs analysis and makes a decision.
