In a method of deploying a virtualised network function (VNF), a virtual network function manager (VNFM) obtains a virtualized network function descriptor (VNFD) that includes a primary file and one or more secondary files that have a mapping relationship with the primary file. The primary file includes a deployment parameter of each secondary file, and a association relationship indicating that a value of a flavour parameter of the VNF is associated with the deployment parameter of the secondary file. The VNFM then determines a target file from the one or more secondary files based on the value of the flavour parameter of the VNF and deploy S the VNF based on the association relationship and a mapping relationship between the primary file and the target file.

Method and apparatus for deploying virtualised network function

A virtualization management method is disclosed. The method includes: A virtual network function manager (VNFM) receives a first instantiation request message of a virtual network function (VNF) sent by a service orchestrator (SO) or a network functions virtualization orchestrator (NFVO), where the first instantiation request message includes a VNF identifier and virtualised infrastructure manager (VIM) information, and the VIM information includes a VIM type and a supported template language. The VNFM obtains a VNF package based on the VNF identifier. When determining that the supported template language of the VIM information is a first template language, the VNFM obtains first VNF sub-information that is consistent with the first template language from template information, where the first VNF sub-information is used to deploy the VNF. The template information is included in a virtual network function descriptor (VNFD) of the VNF package. The VNFM sends the first VNF sub-information to a multi-cloud platform, so that the multi-cloud platform deploys the VNF on a corresponding VIM.

The method includes: An NFVO obtains a VNFD, where the VNFD is for instantiating a VNF, the VNFD includes 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. Then, the NFVO sends an external network instantiation request to a VIM, where the external network instantiation request is used by the VIM to instantiate, based on the resource requirement information of the first internal network, an external network connected to the VNF. Then, the NFVO sends a VNF instantiation request to a VNFM. The VNF instantiation request is used by the VNFM to instantiate the VNF based on the VNFD.

A method and system which provides a solution of cross-platform application deployment, which is based on a Topology and Orchestration Specific for Cloud Applications (TOSCA) template and is compatible with application deployment on other platforms. This solution supports cross-platform application deployment on both a TOSCA platform and a non-TOSCA platform. By adding information about a target platform and application deployment information required for application deployment on the target platform to a deployment template, an upper server performs parsing and sends the application deployment information to the target platform, thereby implementing cross-platform application deployment on the TOSCA platform and the non-TOSCA platform by using one universal template.
