Abstract: An orchestrating apparatus, comprising: a receiving part that receives virtual resource information attached to a VNF (Virtualized Network Function) from a VNFM (Virtualized Network Function Manager) that generated the VNF; a storage part that stores the virtual resource information in correspondence with the VNF; and a synchronizing part that transmits the virtual resource information corresponding to a designated VNF to a VNFM that has lost correspondence between the VNF and the virtual resource information, and causes the VNFM to restore the virtual resource information assigned to the VNF.

Abstract: A network function virtualization management and orchestration apparatus includes a VIM(s) and an upper entity(ies) of the VIM(s). The VIM(s) performs resource management and control of an NFVI(s) that provides an execution infrastructure(s) for a VNF(s) implemented and virtualized by software that operates on a virtual machine(s). The upper entity(ies) collects resource information about the NFVI(s) from the VIM(s) and determines a virtual machine allocation destination(s) based on the collected resource information about the NFVI(s). The VIM(s) generates a virtual machine(s) at the determined virtual machine allocation destination(s).
