Consumer VNF instantiation method and device

The embodiment of the present invention discloses a consumer VNF instantiation method and device and relates to the technical field of communications, for solving the technical problem that NFV in theprior art cannot provide a PaaS service to VNF. The method comprises the following steps: a virtual network layer manager VNFM receives an instantiation request of a consumer virtual network functionVNF sent via a network function virtualization coordinator NFVO; the instantiation request of the consumer VNF carries consumer VNFD of the consumer VNF; the VNFM determines that a target platform corresponding to the consumer VNF is a service PaaS service according to the consumer VNFD; the VNFM obtains an identifier of a target PaaS service; and the VNFM obtains PaaS service information of thePaaS service instance corresponding to the identifier of the target PaaS service according to the identifier of the target PaaS service. The consumer VNF instantiation method and device in the invention can be applied to realiz
