[Abstract] With software-adjusted lightpath transmission, software-programmed lightpath switching, and software-scaled lightpath networking, a software-defined optical network can flexibly change transmission for optical network elements and on-demand allocation of service bandwidth. This is especially important for unified control over heterogeneous networks, virtualized resource provisioning, and datacenter networking. Software-defined optical networking is becoming an important way of heightening the intelligence of optical networks.
