And after the sequence is successfully verified, the network equipment stores the version number successfully verified, and replaces the original basic version number as a new basic version number for carrying out version number verification when the network equipment is configured next time. In the embodiment, the version number is added to the resource change information so that different network resource change requests can be processed in sequence, and the network device can judge the configuration sequence of a plurality of change values according to the version number, thereby preventing the configuration error of the network device when services are concurrent. In a specific example, the basic version number may be 0, and the version number generated based on the basic version number may be obtained by adding 1 to the basic version number, so that the network device may determine whether the sequence of the received version numbers is correct according to the basic version number and the size of the received version number.
