Abstract
Abstract—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) technology, 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 the four-node
photonic mesh network of the ADRENALINE testbed. 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.
