Common service resource application method, related device, and system

A common service resource application apparatus comprising:

• a common service manager (CSM), a virtualized infrastructure manager (VIM), a network functions virtualization orchestrator (NFVO), and a virtualized network function manager (VNFM), wherein
• the CSM includes a processor coupled to a transceiver and is configured to:
• receive resource requirement information of a common service required by a virtual network function (VNF), wherein the resource requirement information of the common service of the VNF comprises a service type, an instance specification, and an instance quantity, and wherein the service type and the instance specification are indicated by a common service member in a virtualized network function descriptor (VNFD), and the instance quantity is indicated by a common service constituent member in a deployment configuration of the VNFD, and
• request, based on the resource requirement information of the common service required by the VNF, the VIM to allocate a resource required by the common service required by the VNF,
• wherein the CSM is configured to receive the resource requirement information of the common service required by the VNF (i) from the NFVO by using an interface between the CSM and the NFVO, wherein the resource requirement information of the common service is sent by the VNFM to the NFVO, or (ii) from the VNFM by using an interface between the CSM and the VNFM, wherein the CSM unifies the respective interfaces for the NFVO and the VNFM to reserve resources and manage lifecycle of the common service;
• and
• the VIM is configured to:
• receive a request for allocating the resource required by the common service required by the VNF, and allocate the resource to the common service.

A non-transitory computer readable storage medium, comprising programming instructions stored thereon, wherein the programming instructions are executable by at least one computer to cause the at least one computer to perform a common service resource application method including:

• receiving resource requirement information of a common service required by a virtual network function (VNF), wherein the resource requirement information of the common service of the VNF comprises a service type, an instance specification, and an instance quantity, and wherein the service type and the instance specification are indicated by a common service member in a virtualized network function descriptor (VNFD), and the instance quantity is indicated by a common service constituent member in a deployment configuration of the VNFD;
• and
• requesting, based on the resource requirement information of the common service required, a virtualized infrastructure manager (VIM) to allocate a resource required by the common service of the VNF,
• wherein receiving the resource requirement information of the common service required by the VNF comprises:
• receiving, from a network functions virtualization orchestrator (NFVO) by using an interface between a common service manager (CSM) and the NFVO, the resource requirement information of the common service required by the VNF, wherein the resource requirement information of the common service is sent by a virtualized network function manager (VNFM) to the NFVO, and wherein the CSM unifies respective interfaces for the NFVO and the VNFM to reserve resources and manage lifecycle of the common service.
