TL;DR: In this paper, an impairment aware network planning and operation tool (NPOT) is proposed to consider the impact of physical layer impairments in the planning of all-optical (and translucent) networks.

TL;DR: A protocol enhancement to manage the power state of optoelectronic interfaces in automatically reconfigurable optical networks for dynamic traffic scenarios and 67% of energy savings have been estimated.

TL;DR: This paper reports the first harmonious integration of an optical flexible hardware framework operated by an agile software and virtualization platform and demonstrates a fully functional complete unification of an advanced optical data plane with an SDN control plane, promising more efficient management of the next-generation data center compute and network resources.

TL;DR: Experimental results validate the successful setup of virtual network slices for intra-data center interconnect and quality of service (QoS) guarantee for high-priority application flows and enable the implementation and experimental validation of load balancing algorithms to improve the QoS performance.

TL;DR: Experimental results show that distributed scheme yields one fifth of setup time required by previously reported alternatives, compared to centralized impairment-aware control plane schemes.
