Introduction
The goal of the ONS department is to contribute in defining the evolution of future transport networks (spanning from metro packet/circuit aggregation to core optical networks) towards intelligent (dynamic, self-star), high-capacity, low-cost, highly-flexible, scalable, and energy-efficient software-defined optical networks seamlessly integrated with massive cloud/fog computing and storage services. To achieve this goal, it focuses on two main research lines: i) Network Control and Service Management, to introduce automated, adaptive and virtualized end-to-end network functionalities in heterogeneous multi-domain networks based on the Software Defined Networking (SDN) and Network Function Virtualization (NFV) paradigms; ii) Optical Transmission and Subsystems to provide SDN-enabled, programmable, adaptive and resource-efficient multi-dimensional optical transmission systems based on multicarrier modulation (MCM) technologies for dynamic and scalable elastic optical networks, as well as advanced performance monitoring and impairment mitigation techniques, fostering photonics technologies/devices to target novel advanced features and cost / energy consumption requirements.
Demonstration and validation of proof of concepts are performed by means of the ADRENALINE Testbed®, an experimental infrastructure designed and developed by the CTTC ONS Department to conduct cutting-edge research activities in the context of: i) end-to-end SDN and NFV services integrating cloud, metro and core networks; ii) coherent and direct detection Optical MCM and programmable multi-adaptive systems for backhaul and backbone networks.
