Management and Orchestration for Network Function Virtualization: An Open Source MANO Approach

Abstract

This paper presents a functional solution for the management and orchestration (MANO) of the Network Function Virtualization (NFV), based on Open Source MANO (OSM). Two different Virtual Infrastructure Managers (VIMs) were tested: OpenVIM and OpenStack. Following the European Telecommunications Standards Institute (ETSI) requirements two experimental scenarios were devised: (1) with OpenVIM in test mode: two Ubuntu 16.04.6 virtual machines (VMs), hosted by different physical computers, acted as two virtual infrastructure managers (VIMs); one of them was collocated with Open Source MANO (OSM); (2) with OpenStack as a VIM and OSM running on an Ubuntu 18.04 virtual machine. The experimental results helped us defined some best practices for integrating OSM with both VIMs. In the future, we plan on extending the infrastructure orchestrated by OSM to include an SDN controller and several clouds acting as VIMs.
