and/or a VNF manager (VNFM) that reads a Virtualized Network Function Descriptor (VNFD) provided with an entry defining dependency between a VM and a prescribed element, and creates the VM and the prescribed element according to the dependency defined in the VNFD. ## Claims ### Claim 1 A virtualization management/orchestration apparatus, comprising: a Network Function Virtualization Orchestrator (NFVO) that reads a Network Service Descriptor (NSD) provided with an entry defining dependency between a Virtualized Network Function (VNF) and a prescribed element, and creates said VNF and said prescribed element according to the dependency defined in said NSD; and/or a VNF manager (VNFM) that reads a Virtualized Network Function Descriptor (VNFD) provided with an entry defining dependency between a Virtual Machine (VM) and a prescribed element, and creates said VM and said prescribed element according to the dependency defined in said VNFD. ### Claim 2 (depends on 1) The virtualization management/orchestration apparatus according to claim 1, wherein said NSD comprises an entry of an identifier of said VNF, and an identifier of said prescribed element to be created before or created after said VNF. ### Claim 3 (depends on 1) The virtualization management/orchestration apparatus according to claim 1, wherein said VNFD comprises an entry of an identifier of said VM, and an identifier of said prescribed element to be created before or created after said VM. ### Claim 4 (depends on 1) The virtualization management/orchestration apparatus according to claim 1, wherein said NFVO confirms whether or not there is a constraint violation among plural dependencies defined in said NSD. ### Claim 5 (depends on 1) The virtualization management/orchestration apparatus according to claim 1, wherein said VNFM confirms whether or not there is a constraint violation among plural dependencies defined in said VNFD. ### Claim 6 (depends on 5) The virtualization management/orchestration apparatus according to claim 5, wherein said VNFM creates a plurality of creation sequences representing sequences of creating VMs and prescribed elements in accordance with plural dependencies defined in said VNFD, and adjusts the sequences in the plurality of creation sequences so that the constraint violation does not occur among said created plurality of creation sequences. ### Claim 7 (depends on 1) The virtualization management/orchestration apparatus according to claim 1, wherein said NSD comprises an entry defining dependency related to a creation sequence among a VNF and at least one of another VNF, an external NW and storage, and/or said VNDF comprises an entry defining dependency related to a creation sequence among a VM and at least one of another VM, an external NW, an inter-VNFC NW, and storage. ### Claim 8 A virtualization management/orchestration method, comprising: reading a Network Service Descriptor (NSD) provided with an entry defining dependency between a Virtualized Network Function (VNF) and a prescribed element, and/or a Virtualized Network Function Descriptor (VNFD) provided with an entry defining dependency between a Virtual Machine (VM) and a prescribed element; and creating said VNF and said prescribed element in accordance with said NSD, and/or creating said VM and said prescribed element in accordance with said VNFD. ### Claim 9 (depends on 8) The virtualization management/orchestration method according to claim 8, wherein said NSD comprises an entry of an identifier of said VNF, and an identifier of said prescribed element to be created before or created after said VNF. ### Claim 10 (depends on 8) The virtualization management/orchestration method according to claim 8, wherein said VNFD comprises an entry of an identifier of said VM, and an identifier of said prescribed element to be created before or created after said VM. ### Claim 11 (depends on 8) The virtualization management/orchestration method according to claim 8, comprising a step of confirming whether or not there is a constraint violation among plural dependencies defined in said NSD. ### Claim 12 (depends on 8) The virtualization management/orchestration method according to claim 8, comprising a step of confirming whether or not there is a constraint violation among plural dependencies defined in said VNFD. ### Claim 13 A non-transitory computer-readable recording medium storing a virtualization management/orchestration program executing on a computer: a process of reading a Network Service Descriptor (NSD) provided with an entry defining dependency between a Virtualized Network Function (VNF) and a prescribed element, and/or a Virtualized Network Function Descriptor (VNFD) provided with an entry defining dependency between a Virtual Machine (VM) and a prescribed element; and a process of creating said VNF and said prescribed element in accordance with said NSD, and/or creating said VM and said prescribed element in accordance with said VNFD. ### Claim 14 (depends on 13) The program according to claim 13, wherein said NSD comprises an entry of an identifier of said VNF, and an identifier of said prescribed element to be created before or created after said VNF. ### Claim 15 (depends on 13) The program according to claim 13, wherein said VNFD comprises an entry of an identifier of said VM, and an identifier of said prescribed element to be created before or created after said VM. ### Claim 16 (depends on 13) The program according to claim 13, comprising executing on a computer a process confirming whether or not there is a constraint violation among plural dependencies defined in said NSD. ### Claim 17 (depends on 13) The program according to claim 13, comprising executing on a computer a process confirming whether or not there is a constraint violation among plural dependencies defined in said VNFD.
