Networks have been the main method of transferring data for more than forty years. The traffic volumes and sizes of networks have increased considerably in the last two decades. The traditional methods used in the networks to transfer data become inefficient due to this growth. Therefore, network planning and smart delivery methods have gained importance. Accordingly, traffic engineering methods are deployed to meet the faster and more efficient delivery requirements. These methods have been proven beneficial and they are still being used on every level of networking. Recently, software defined networking redefined the architecture of networks and network devices. This new architecture paved the way for more flexible network and traffic management techniques. In this thesis, we propose a new routing method, which minimizes the maximum link utilization in the software-defined networks. The proposed method defines a new cost metric based on statistical inference to distribute load evenly in the network. The method is demonstrated, and its performance is evaluated on virtual software defined network topologies under various artificial network loads. The experiments show that the proposed algorithm achieves the even distribution of traffic and minimizes the maximum link utilization in software defined networks.
