5G-Crosshaul

The 5G-Crosshaul project aims at developing a 5G integrated backhaul and fronthaul transport network enabling a flexible and software-defined reconfiguration of all networking elements in a  multi-tenant and service-oriented unified management environment.

The 5G-Crosshaul transport  network envisioned will consist of high-capacity switches and heterogeneous transmission links (e. g., fibre or wireless optics, high-capacity copper, mmWave) interconnecting Remote Radio Heads,  5GPoAs (e.g., macro and small cells), cloud-processing units (mini data centres), and points-of- presence of the core networks of one or multiple service providers. This transport network will  flexibly interconnect distributed 5G radio access and core network functions, hosted on in- network cloud nodes, through the implementation of: (i) a control infrastructure using a unified,  abstract network model for control plane integration (Crosshaul Control Infrastructure, XCI); (ii) a unified data plane encompassing innovative high-capacity transmission technologies and novel deterministic-latency switch architectures (Crosshaul Packet Forwarding Element, XFE). The 5G- Crosshaul proposal addresses the ICT 14-2014 call of the Horizon 2020 Work Programme 2014-15  with a special focus on the P7 objectives defined by the 5GPPP IA.
