Towards an SDN/NFV-based multi-tenant network and cloud testbed for end-to-end 5G services

Abstract

5G has a main requirement of highly flexible, ultralow latency and ultra-high bandwidth virtualized infrastructure in order to deliver end-to-end services. This requirement can be met by efficiently integrating all network segments (radio access, aggregation and core) with heterogeneous wireless and optical technologies (5G, mmWave, LTE/LTE-A, Wi-Fi, Ethernet, MPLS, WDM, software-defined optical transmission, etc.), and massive computing and storage cloud services (offered in edge/core data centers, and even, distributed in network nodes). This paper introduces the preliminary architecture aiming at integrating three consolidated and standalone experimental in- frastructures at CTTC, in order to deploy the required end-to- end top-to-bottom converged infrastructure pointed out above for testing and developing advanced 5G services. The existing experimental facilities cover complementary technologies from terminals to radio access, aggregation/core and cloud, and are: the GEDOMIS R testbed (LTE/5G PHY testbed), the EXTREME Testbed R (wireless HetNet and backhaul, edge datacenter,a d distributed computing nodes), and the ADRENALINE Testbed R (packet aggregation and optical core network, core data-center). Two uses cases addressing Fixed Mobile Convergence (FMC) developed in ADRENALINE and EXTREME, and virtual mobile network function splitting and deployment, involving EXTREME and GEDOMIS, are also presented
