The paper presents the secure based Traffic Engineering Model in softwarized networks. The proposed mathematical model belongs to the class of flow solutions and is a development of the classic Traffic Engineering model. The novelty of proposed model is the modification of the load balancing conditions in the software-defined network, which in addition to bandwidth (service quality indicator) also takes into account the probability of compromising it (network security indicator). Within the proposed model, the obtained routing solutions are aimed at reducing the load on communication links, which have a high probability of compromise, by redirecting traffic to more reliable ones. The numerical example demonstrates the efficiency of the model and the adequacy of the obtained route solutions.
