Experimental demonstration of distributed multi-tenant cloud/fog and heterogeneous SDN/NFV orchestration for 5G services

It is expected that in 5G networks billions of smart devices will generate huge aggregated volumes of data that will be processed in distributed cloud/fog infrastructure. To this end, it is required an integrated management of the network and the cloud resources forming a converged end-to-end system. Software Defined Networking (SDN) and Network Function Virtualization (NFV) architectures are the key enablers to integrate both network and cloud resources, enabling cross-optimization in both sides. This paper presents the experimental activities related to 5G services using the ADRENALINE testbed located at CTTC premises in Castelldefels (Barcelona, Spain). SDN orchestration is presented as a feasible and scalable solution for providing end-to-end connectivity between heterogeneous networks and cloud/edge computing. Moreover, we present the demonstration of an SDN/NFV orchestrator to dynamically create virtual backhaul tenants over a multi-layer (packet/optical) aggregation network and deploy virtual network functions to better adapt the capacity increase of Mobile Network Operators.
