Zusammenfassung:	There is provided a network node and method for placement of virtual network functions managers (VNFMs) in a network functions virtualization (NFV) system. The method comprises determining a number of VNFMs for the NFV system, determining a type for each VNFM, determining a placement for each VNFM over distributed Network Function Virtualization Infrastructure Points of Presence (NFVI-PoPs) and determining a plurality of associations between the VNFMs and VNF instances in the system, thereby generating a VNFMs placement solution.
