Future traffic patterns in transport networks will be much more volatile than today due to emerging applications like connected cars or the Internet of Things. The multitude and frequency of change of their connections requires a high level of automation for which an SDN-controlled network architecture is indispensable. We therefore present three SDN-based reconfiguration approaches covering QoS-aware routing, load balancing and optical band defragmentation. We show that the presented approaches are capable of handling such volatile traffic and are improving network efficiency.
