NFV Manager. The NFV Manager takes care of handling the experiment’s NFV resources. It communicates with Open Baton’s Network Function Virtualization Orchestrator (NFVO) using its REST API. In case of an experiment deployment it uploads a Network Service Descriptor (NSD) in TOSCA format to the NFVO and triggers the deployment of a Network Service Record (NSR). When the experiment is deleted it removes the NSR and NSD from the NFVO. The NFV Manager sends the NSR’s status periodically to the EM. Furthermore, the NFV Manager is involved in the creation and removal of SoftFIRE users. For this it interfaces the OpenStack testbeds. In the process of user creation, it creates a new OpenStack user and project and a new Open Baton user and project. When removing a SoftFIRE user, it removes also the Open Baton and Open Stack users and projects. It also makes sure that there are no leftovers in Open Stack after deleting the user and project. The NFV Manager provides two NFV resources to the experimenters, which they can use out of the box. One is a VNF for deploying an iPerf server and client in two virtual machines and the other one is the Open IMS Core which is an Open Source implementation of IMS Call Session Control Functions (CSCFs) and a lightweight Home Subscriber Server (HSS), which together form the core elements of all IMS/NGN architectures as specified today within 3GPP, 3GPP2, ETSI TISPAN and the PacketCable initiative. Besides the two provided Network Services (NS) the experimenters can use their own CSAR files for describing the NS they want to deploy.
