Optical Networks & Systems

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:

  1. Network Control and Service Management, to perform research on advanced service and resource control and orchestration, in an environment characterized by automated, adaptive and virtualized end-to-end infrastructures encompassing both heterogeneous multi-domain networks spanning access, aggregation metro and backbone network segments and geographically distributed computational resources, extending the Software Defined Networking (SDN) and Network Function Virtualization (NFV) principles, main concepts and models;
  2. Optical Transmission and Subsystems to provide SDN-enabled, adaptive and resource-efficient multi-dimensional transmission systems based on optical OFDM for dynamic and scalable elastic optical networks, as well as advanced performance monitoring and impairment mitigation techniques.

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 OFDM systems for backhaul and backbone networks.
