The first live demonstration of the blueSPACE NFV MANO platform for SDM networks was shown at the European Conference on Optical Communications (ECOC) 2018 on the 25th of September 2018 at demo session TuDS.2 from 12:30 to 17:00. It was very successful and many attendees from the industry and academy came to the booth to know more details. The demonstration was carried out by blueSPACE consortium members CTTC and Nextworks.
The integration of the transport SDN controller into the NFV MANO framework is key for the deployment of NFV network services for 5G. We presented the developed extensions for the control of SDM/WDM-enabled fronthaul and packet-based backhaul transport networks, in order to offer NFV network services. We have developed a novel hierarchical transport SDN solution for the fronthaul/backhaul networks that extends the Open Networking Foundation (ONF) transport API (TAPI) as the northbound interface towards the NFV service platform. Additionally, we also presented the YANG data models for the control of the central offices and the cell site nodes. We have also extended the NFV MANO framework with an NFV orchestrator able to configure the underlying transport networks, as an integrated part of the resource allocation procedures, interacting with the transport SDN controller.
In the demonstration, we targeted the experimental validation of NFV network services using an NFV orchestrator supporting the extended TAPI. NFV network services were deployed by instantiating VNFs located in the edge datacentre of the central office and automatically provisioning the required connectivity through the developed transport SDN controller using the extended TAPI. In the demo environment, the optical network data plane was emulated together with the RRHs and BBUs (modelled as particular network nodes), while an OpenStack instance controlled compute nodes representing the central office.
