A method and a device for obtaining virtual resources are provided and used for solving the current problems of the long time to obtain virtual resources and the waste of system resources in the process of obtaining virtual resource in a VNF. The VNF sends a VDU model obtaining request to a VNFM, which indicates a NFVO to obtain the VDU model that the VIM can offer, and sends the obtained VDU model to the VNF; according to the VDU model, the VNF calculates and obtains the number of VMs needed when the VDU model is applied, and then requests the VIM to obtain the virtual resources corresponding to the number of VMs. With the technical solution, the VNF is not required to consult with a VNFM for several times to determine the type of the VDU model, the signaling interactions between the VNF and the VNFM are reduced, and the efficiency of obtaining a VNF virtual resource is improved. |
