[Abstract] Software-defined optical networks (SDONs), which is characterized by the software-defined networks (SDNs) optical control plane, represent the trend of future transport networks. SDONs enable new-type ultralarge-capacity optical networks to achieve a high degree of intelligence. SDONs enable the structure and functionality of optical networks to be customized through software. They also enable optical device configuration, transmission parameter adjustment, and elastic bandwidth allocation by introducing a control plane solution based on SDNs. It perfectly caters for the novel architecture of intelligent optical networks. The innovative application of SDONs has become a new research direction.
