This paper focuses on a Hybrid-SDN approach, which is able to narrow this gap via a more natural split of local and remote control functions. The described horizontal split keeps the impact on network design and operation less revolutionary and therefore such a Hybrid-SDN approach could provide a more realistic introduction of SDN in real transport network scenarios.
