Abstract
The programmability of upcoming transport optical networks is handled by a centralized Transport SDN (T-SDN) controller. The T-SDN controller dynamically computes and selects the resources to automatically accommodate optical connection requests by configuring the involved network elements and devices (i.e., optical switches and transceivers). Additionally, the T-SDN controller should provide management functions to ensure high reliability and correct service status in terms of QoS, QoT, failure detection, etc. during the whole connection duration. These management functions are typically addressed by the operation, administration and maintenance (OAM) Handler. ...
