Metro-Haul - METRO High bandwidth, 5G Application-aware optical network, with edge storage, compUte and low Latency (H2020)

The overall Metro-Haul objective is to architect and design cost-effective, energy-efficient, agile and programmable metro networks that are scalable for 5G access and future requirements, encompassing the design of all-optical metro nodes (including full compute and storage capabilities), which interface effectively with both 5G access and multi-Tbit/s elastic core networks. Metro-Haul has taken the 5G KPIs and already determined their implication for the optical network with these 5 targets: (i) 100 x more 5G capacity supported over the same optical fibre infrastructure, (ii) 10 times less energy consumption, (iii) Latency-aware metro network in which latency-sensitive slices are handled at the metro edge ensuring the metro network adds no additional latency, (iv) End to end SDN-based management framework enabling fast configuration time to set up or reconfigure services handling 5G applications, specifically 1 minute for simple network path set-up and 10 minutes for full installation of a new VNF and 1 hour for setting up a new virtual network slice and (v) reduction in CAPEX of a factor of 10, plus a reduction in OPEX of at least 20%.


ONOFRE 2 - Optical Networks Convergence in the Future Internet 2 (TEC2017-84423-C3-1-P)

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.


ElasticNetworks (TEC2015-71932-REDT)

A number of studies have pointed out on the dramatic increase of Internet traffic exchanged worldwide, around 23% accumulated per year anual, estimated to reach 168 Exabytes exchanged per month by 2019, approximately 22 GB per person. Such an increase is based on several reasons: on one hand the explosive growth of mobile devices along with their popularity and low-cost (estimated 20 billion by 2020); on the other hand the rise and popularity of new interactive services with strict high-bandwidth low-delay requirements, namely video on-demand, online gaming, P2P file sharing, etc. On top of these, the rise of Smart Cities, Internet of Things, Cloud Computing and Big Data suggest that such a percentage of traffic increase may have been underestimated. ElasticNetworks will address the above challenges and will focus on a number of novel approaches for the design of the Future Internet. In particular, ElasticNetworks will contribute to a holistic redesign of the transport network towards a more agile, flexible, programmable Elastic Network, yet with low operation, deployment and maintenance cost, and energy efficient

ONOFRE - Optical Networks cOnvergence in the FutuRE Internet (TEC2014-53071-C3-1-P)

ONOFRE project is focused on an access/metro network convergent design, investigating the effects of NGPON2 and NGPON3 evolutions. Dynamic Bandwidth Allocation (DBA) mechanisms are studied in depth, analyzing how QoS and clock synchronization requirements constraint the network design. Another goal is to investigate on-demand resource allocation schemes that behave efficiently under high traffic variability scenarios in the ROADM-based multilayer optical metro. Moreover in ONOFRE project we seek on implementing an OpenFlow (SDN) framework for a converged access/metro control plane suitable for this scenario.
