Demonstration of Adaptive SDN Orchestration: A Real-Time Congestion-Aware Services Provisioning Over OFDM-Based 400G OPS and Flexi-WDM OCS

In this Paper, we experimentally demonstrate highly flexible and intelligent interdomain coordinated actions based on adaptive software-defined networking (SDN) orchestration. An advanced multidomain multitechnology testbed is implemented, which …

SDN-Enabled Sliceable BVT Based on Multicarrier Technology for Multiflow Rate #x002F;Distance and Grid Adaptation

We propose a sliceable bandwidth variable transceiver (S-BVT) architecture suitable for metro/regional elastic networks and highly scalable data center applications. It adopts multicarrier modulation, either OFDM or DMT, and a cost-effective …

SDN-Enabled Sliceable BVT Based on Multicarrier Technology for Multi-Flow Rate/Distance and Grid Adaptation

We experimentally demonstrate multiple advanced functionalities of a cost-effective high-capacity sliceable-BVT using multicarrier technology. It is programmable, adaptive and reconfigurable by an SDN controller for efficient resource usage, enabling …

IDEALIST Data Plane Solutions for Elastic Optical Networks

The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable, for …

Chirp and Frequency Offset Tolerant Coherent Burst-Mode Receiver Using Directly Modulated DFB Lasers for Coherent PON Systems

Burst-mode receiver (BMR) is one of the key components in passive optical networks (PONs). When directly-modulated distribution feedback (DFB) lasers are used as transmitter source, the BMR needs to take additional measures to compensate the effects …
