In this paper, we review current initiatives of SBI to control optical components which include ad-hoc extensions of OpenFlow and YANG modelling proposals combined with the NETCONF / RESTCONF protocols. Then we overview different tools and frameworks available for quick prototyping and deployment of software services that are compliant with such interfaces. Finally, we discuss the advantages and drawbacks of the reviewed initiatives considered key enablers for standardized end-to-end network programmability.

Moreover, its increasing heterogeneity is driving research trends in network functions virtualization and software-defined networking (SDN) to guarantee high levels of reconfigurability, adaptability, and flexibility. Therefore, hardware infrastructures must be capable of playing different roles according to service and traffic requirements. In this context, reconfigurable optical add/drop multiplexers (ROADMs) are key elements since they route signals directly in the optical domain. Thus, it is crucial to design ROADMs with easy maintenance, a low manual intervention rate, and high reconfigurability, flexibility, and adaptability. In this work, we experimentally demonstrate our recently proposed add/drop on demand (ADoD) architecture for ROADMs in a SDN metropolitan mesh optical network test-bed with 80 dual-polarization quadrature phase-shift-keying channels at 128 Gb/s. In addition, we extend our quantitative measurement of flexibility considering the system’s entropy, showing that ADoD provides higher flexibility and lower loss than current proposals.

Results show that AoD can bring energy savings at node level.
