The invention discloses an SDDCN energy-saving routing method, system and device based on bandwidth matching, and a storage medium, and the method comprises the steps: sorting data streams needing to be transmitted according to the deadline of the data streams, and then updating link weights in a topology according to the data volume needing to be transmitted of each sorted data stream; and deleting the links of which the available bandwidths do not meet the transmission data volume to obtain a new topological graph. And in the redefined topological graph, all available links between the source node and the target node are calculated, and a link which is most matched with the bandwidth required by the flow transmission data volume is selected from the available links for routing. According to the method, the energy-saving and flow load balancing scheme in the DCNs is researched, the network throughput is improved while the network energy consumption is reduced, and the method is of great significance. 本发明公开了基
