Project ONOFRE-2

Optical Networks Convergence in the Future Internet - 2

What is ONOFRE-2?

Optical fibre and 5G infrastructures are key technologies to support the Future Internet. Emerging paradigms like the Internet of Things (IoT), Industry 4.0 or the tactile internet impose stringent requirements that current networks cannot provide. In the area of backhaul infrastructure, optical access and metro networks are evolving to address the continuous increase in traffic volume, traffic dynamicity and number of connected devices, while providing low latencies. In the access network segment, Passive Optical Networks (PONs) are the best infrastructure to provide high bandwidth in a cost-effective way. In the metro segment, the adoption of elastic infrastructure in combination with an efficient and open control layer based on SDN (Software-Defined Networks) can prepare the backhaul to deal with the future applications and services. In this context, the integration of both access and metro networks is a must. Two key technologies for that aim are network function virtualization (NFV) and, again, SDN. These technologies will allow for the support of every kind of service while being efficient from the point of view of energy consumption (and, hence, CO2 emissions) and costs.

ONOFRE-2 aims at extending the capabilities offered by the converged access/metro network designed in the previous national project ONOFRE by encouraging NFV techniques over a virtualized infrastructure. Virtualization, together with the use of the MEC paradigm, enable both energy consumption and cost reductions, and open the door to new IoT or tactile Internet services. The novelties of ONOFRE-2 are (1) the proposal of architectures, planning methods and holistic control techniques for converged access/metro networks able to comply with the requirements of 5G, IoT and Tactile Internet services, (2) the introduction of the MEC paradigm as a key ingredient to attain the previous objective, and (3) the use of SDN and NFV techniques as additional enabling tools.
