A network function virtualization system, comprising: a single-domain virtualized network function manager (VNFM), a single-domain virtualized network function (VNF) entity, and a virtualized infrastructure manager (VIM); one or more network function virtualization single-domain organizers (NFV-DO), the NFV-DO corresponding to single domains on a one-to-one basis, and the NFV-DO comprising: a virtualized network function organizer (VNFO) arranged to manage any one or more functions of the single domain in which it is located as follows: a network service instance, a network service life cycle, VNFM instantiation, VNF instantiation, and the life cycle of the VNF. The solution can satisfy the requirement of phased evolution, and the requirement of cross-border, cross-region and multi-manufacturer service provision and multi-layer management implemented in current NFV systems. |
