We propose a sliceable bandwidth variable transceiver (S-BVT) architecture suitable for metro/regional elastic networks and highly scalable data center (DC) applications. It adopts multicarrier modulation (MCM), either OFDM or DMT, and a cost-effective optoelectronic front-end. The high-capacity S-BVT is programmable, adaptive and reconfigurable by an SDN controller for efficient resource usage, enabling unique granularity, flexibility and grid adaptation, even in conventional fixed-grid networks. We experimentally demonstrate its multiple advanced functionalities in a four-node photonic mesh network. This includes SDN-enabled rate/distance adaptive multi-flow generation and routing/switching, slice-ability, flexibility and adaptability for the mitigation of spectrum fragmentation as well as for a soft migration towards the flexi-grid paradigm.

A multi-domain and multi-technology optical network orchestration is demonstrated in an international testbed located in Japan, the UK and Spain. The Application-Based Network Operations (ABNO) architecture is proposed as a carrier Software-Defined Network (SDN) solution for provisioning end-to-end optical transport services through a multi-domain multi-technology network scenario, consisting of a 46-108 Gb/s variable-capacity OpenFlow-capable optical packet switching network and a programmable, flexi-grid elastic optical path network.
