Measurement-as-a-Service: VNF-to-VNF Performance Measurement in Federated Testbed

In 5G and beyond, Network Function Virtualization (NFV) and Software Defined Networking (SDN) technologies enables an easy deployment of Virtualized Network Functions (VNF). However, designing and building scalable NFV infrastructure is quite challenging to adopt and making VNFs deployment on existing hardware. To understand such behaviour, the EU SoftFire project developed federated virtualization testbed for NFV/SDN experiments. This paper outlines the SoftFire Middleware framework and proposes an automated Measurement-as-a-Service (MaaS) for performing VNF-to-VNF performance metrics, such measurements can be exploited by an orchestrator to perform VNF instantiate selection.
