Claim 10:
11. A virtualized network function (VNF) instantiation method, comprising:
sending, by an operations support system/business support system (OSS/BSS), virtualized network function description information (VNFD) to a network functions virtualization orchestrator (NFVO);
receiving, by the NFVO, the VNFD from the OSS/BSS, wherein the VNFD is for instantiating a VNF, the VNFD comprises first indication information and resource requirement information of a first internal network, and the first indication information indicates that the resource requirement information of the first internal network is externally visible;
sending, by the NFVO, an external network instantiation request to a virtualized infrastructure manager (VIM);
receiving, by the VIM, the external network instantiation request;
instantiating, by the VIM using the external network instantiation request and based on the resource requirement information of the first internal network, an external network connected to the VNF;
sending, by the NFVO, a VNF instantiation request to a virtualized network function manager (VNFM);
receiving, by the VNFM, the VNF instantiation request; and
instantiating, by the VNFM using the VNF instantiation request and based on the VNFD, the VNF.
