In the first part of this thesis we are going to cover an introduction of ETSI NFV Framework and the architecture around it. Mention will be made in the current network architecture and the limitation of existing mode, the advantages of new technologies and a history behind NFV Framework. Afterwards an in depth theoretical study of high and low level of ETSI MANO, in order for the reader to get familiarize with all the layers surround it such as VIM, VNFM, Operation and Orchestration layer and NFV reference points. Second part of this thesis is dedicated in the OSM MANO, an ETSI hosted open source MANO, closely aligned with ETSI NFV. Reader will educate upon OSM history, the scope of NFV, the mapping of OSM to ETSI NFV MANO, MANOs software components such as Interfaces, EPA characteristics, NSDs, VNFDs and VLD. We will cover how OSM MANO is architected, the key components of it, how every key component is configured and the interconnections between them. As NFV are using also SDN technologies, we will also mention how NFV and SDN are collaborated in order that this new network model, of detached software from hardware will be a common established ground, in the future. We will also briefly mention some of the projects that help OSM MANO come to life (LXD, Cloud Platforms, Openstack, OpenDayLight). In the third and last section of this thesis we will see how OSM is installed, what are the specifications around it, a day 0 to day 2 configuration, OSM three new features compared with one and two, and our experiences and problems with the installation.
