A consortium of 20 industry-leading companies, including NEC, have successfully completed a nearly three-year European Union Horizon 2020 project aimed at developing a 5G integrated backhaul and fronthaul transport network — the project, 5G-Crosshaul, is now the de-facto concept for the 5G integrated fronthaul/backhaul transport network.
The 5G-Crosshaul consortium was selected in 2015 to develop a 5G integrated backhaul and fronthaul transport network that enables a flexible and software-defined reconfiguration of all networking elements in a multi-tenant and service-oriented unified management environment. The transport network flexibly interconnects distributed 5G radio access and core network functions hosted on in-network cloud nodes. This is achieved through the implementation of a control infrastructure using a unified, abstract network model for control plane integration and a unified data plane encompassing innovative high-capacity transmission technologies, as well as novel deterministic-latency switch architectures.
The 5G-Crosshaul solution was demonstrated and validated through 18 experiments integrating multiple technology components from the partners. Real-world trials took place at sites in Berlin, Madrid, Barcelona and Taiwan, and delivered sub-millisecond latency, tens of Gbps throughput, and proven energy and cost savings up to 70%, depending on the deployment scenario. The trials also demonstrated fast service deployment time in the order of minutes, taking advantage of SDN and NFV concepts.
Following its final project review by independent experts appointed by the European Commission, the 5G-Crosshaul project was declared to "have fully achieved its objectives and milestones and delivered exceptional results with significant immediate or potential impact". The EU experts report highlighted "Significant results linked to dissemination, exploitation and impact potential", in particular:
- 91 papers - in several prestigious journals
- 74 presentations/panels/webinars, and 14 (Co-)organized workshops
- 28 demonstrations, including at flagship events such as MWC'16 and MWC'17
- 35 normative contributions feeding into key standardization specifications of eCPRI, G.metro, IETF CCAMP, IETF DETNET, and ONF
- 25 contributions for information purposes in several standardization bodies such as NGMN, ITU-T, FSAN, ETSI, IEEE, BBF, ONF.
