Summary The lack of a Management Plane specification in the software‐defined networking (SDN) is a fundamental problem for the integrated management of networks that follow this paradigm. Several solutions have addressed this problem, but they do not provide data models intended to support Fault, Configuration, Accounting, Performance, and Security (FCAPS) in SDN from a specialized Management Plane. In this paper, we introduce a technology‐agnostic approach that comprises mainly a collection of YANG data models and their relationships. These models characterize SDN management and handle technology heterogeneity. To evaluate our approach, we developed the proof of concept of the YANG data models in an SDN scenario involving the configuration of devices from different vendors supporting diverse technologies. The evaluation results show the efficiency of our approach regarding response time, composition time, consumption time, and network traffic.
