5G-Crosshaul project

Visiona contributed to the 5G-Crosshaul project by developing the TVBA, TV Broadcasting Application, and a virtual quality probe that analyses video QoS and QoE.

 

The TVBA uses the 5G-Crosshaul platform to deploy and provide a full broadcasting environment in seconds. Additionally, the TVBA deploy a virtual quality probe in the last node of the network, just before the user. This allows the TVBA from a non-intrusive manner to know the quality of the video the user is receiving. In case that the QoS or QoE metrics don’t meets the expectations, the TVBA is able to act over the network and reconfigure the network path from the source to the users.

 

The TVBA rely on Openbaton as the MANO software that interacts with the Openstack as a VIM to deploy our VNFs in the selected nodes as needed. The VNFs defined and developed in the TVBA are:

–        Virtual Quality Probe: detect QoS and QoE errors without referent image as color errors, packet loss, freezing, audio errors and total video loss.

–        Virtual Video Headend: streams the video the users receive.

OpenDayLight is the SDN controller that allow the TVBA to set new and reconfigure the network paths to connect the video headend to the users.

 

A friendly web interface is in charge of presenting the full solution so the tenant that is operating the TVBA can with see the full network and deploy and provide services in some clicks.

 

5G-Crosshaul H2020 project

  • Audiovisual Sector
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.
