1. A method implemented by a network functions virtualization orchestrator (NFVO), wherein the method comprises:
creating virtualized network function package information (VNFPI) for each virtualized network function (VNF) included in a network service (NS);
obtaining a node type of each VNF from a respective VNF package (VNFP) corresponding to the VNF, wherein the VNFP comprises a VNF descriptor (VNFD);
associating the node type with the respective VNFPI;
obtaining a first identifier of the VNFD indicating the VNFD from each VNFP;
storing the first identifier of the VNFD in the respective VNFPI;
receiving a NS instantiation request for the NS;
providing network service description information (NSD) based on the NS instantiation request, wherein the NSD comprises the node type of each VNF;
obtaining the respective VNFPI associated with the node type;
obtaining the first identifier of the VNFD from the respective VNFPI; and
requesting, based on the first identifier, a virtualized network function manager (VNFM) to instantiate the respective VNF.
