A method includes obtaining a first service requirement related to a first device; determining, based on the first service requirement, a first host core model and at least one component hooked to the first host core model; generating a first packet based on the host core model and the at least one component; and configuring the first device based on the first packet. Because a configuration apparatus can run independently of a device that is in a service requirement, configuration can be completed on the device based on the service requirement when a service of the device is not broken. Difficulty in configuration can be effectively reduced by hooking the component to the host core model.
