Use Case of a Management and Orchestration for Network Functions Virtualization in a VoIP Testbed

This paper examines a practical approach for Network Functions Virtualization (NFV) management and orchestration (MANO) based on the Open Source MANO (OSM). The proposed testbed uses the OSM Open Source orchestration platform, in order to handle and orchestrate the NFV Voice over Internet Protocol (VoIP) in OpenStack used as Virtual Infrastructure Manager (VIM). On top of this, we implemented Software-Defined Networking (SDN) by means of the Open Network Operating System (ONOS) controller and Open vSwitch. Our experiments show that the solution is feasible, with the latency, jitter, packet-loss and Mean Opinion Score (MOS) all within the range.
