Abstract: Disclosed are a method and apparatus for modeling a network configuration protocol (NETCONF)-based network device instruction with a yet another next generation (YANG) language. The method of modeling the NETCONF)-based network device instruction with the YANG language includes: searching for at least one instruction from a source file for controlling a NETCONF-based network device; parsing the retrieved instruction into a plurality of tokens; mapping each parsed token with a data type of the YANG language according to a previously defined mapping rule; and generating a YANG model corresponding to the at least one instruction according to mapping results. Accordingly, the YANG model is immediately generated reflecting changes in an instruction of a network system.

Abstract: An operation method of a server in a communication system may comprise receiving device information from each of a plurality of devices; generating service modeling information for each of a plurality of services; generating category modeling information for sub-services of each of the plurality of services based on the device information and the service modeling information; receiving service information; generating device modeling information corresponding to the category modeling information based on the service information; and transmitting the device modeling information to each of the plurality devices corresponding to the device modeling information, wherein the device modeling information includes configuration information for a network service function corresponding to a device corresponding to the device modeling information.
