Therefore, after the control plane generates the flow table, the generated flow table is directly issued to the data plane of the kernel mode, the data plane can be directly forwarded based on the flow table in the data plane after receiving the network flow, and compared with the prior art that the flow table is not hit in the data plane, the kernel mode and the user mode need not be switched back and forth, the method and the device do not need to be switched back and forth between the user mode and the kernel mode, the processing time of the network flow in the SDN network is saved, and the data transmission efficiency is improved.
Step S13: and storing the flow table through the data surface, and forwarding the input network flow based on the flow table when the input network flow is received.
