Provisioning of optical connectivity. The provisioning of optical connectivity is the service in charge of establishing dynamic optical paths over the data centre network infrastructure, to provide the connectivity required to support overlay virtual networks or data centre management tasks which require the exchange of large bulks of data across the network. The service is implemented by an internal module of the SDN controller and exposes a REST API, compliant with the RESTCONF protocol, to create, modify, retrieve and delete optical connections. The consumers of the service are the overlay-based network virtualization application, the cloud orchestrator or a management platform for the administration of the whole data centre.
