Multi-modal network control-data plane consistency verification method and device

The invention provides a multi-modal network control-data plane consistency verification method and device. The method comprises the following steps: loading a consistency verification component in a multi-modal network control plane, and loading a probe generation component and a log sampling component in a multi-modal network data plane, wherein the probe generation component injects detection flow into a network, so that the detection flow is forwarded through a data plane; using the log sampling component for sampling, analyzing and sorting the detection flow which is forwarded and output by the data plane, and sending a sorting result to the consistency checking component; and enabling the consistency verification component to compare a network configuration information analysis result in the control plane with a sorting result generated by the log sampling component to complete verification work, wherein the network configuration information analysis result and the sorting result generated by the log sa
