Figure 1 illustrates a flow diagram of a method of deploying a virtualized network function, VNF, entity, in accordance with some embodiments of the present disclosure. The method may be performed by, for example, a network function virtualization orchestrator NFVO.
As shown in FIG. 1, the method of this embodiment includes steps 101-105.
In step 101, the nfvo determines a corresponding virtualized network function manager VNFM according to the VNF entity to be deployed.
In VNF technology, the NFVO may host one or more VNFMs and one or more VIMs, where each VIM may be called by one or more VNFMs, and accordingly, each VNFM may also call one or more VIMs.
The NFVO determines a corresponding VNFM according to a VNF entity to be deployed, and the VIM managed by the VNFM can be used for deploying the VNF entity. According to the VNF entity to be deployed, the preset attribute information required for deploying the VNF entity, such as the preset capability attribute information, the preset location attribute information, the preset usage attribute information, and the like, may be determined, which is not limited to the illustrated example.
At step 102, the nfvo obtains attribute information for each virtualized infrastructure manager VIM that it sets up to manage by the VNFM.
The NFVO sets corresponding attribute information for each virtualization infrastructure manager VIM, and acquires the attribute information of the VIM set by the NFVO. The attribute information of the VIM includes, for example, capability attribute information, location attribute information, and usage attribute information of the VIM, and is not limited to the illustrated examples.
The capability attribute information includes a capability of the VIM to support a preset mobile communication technology, for example, a capability of the VIM to support a 3G/4G/5G (not limited to the illustrated example) mobile communication technology. The location attribute information includes that the VIM is a VIM in an edge VIM resource pool, or the VIM is a VIM in a core VIM resource pool. The usage attribute information may include, for example, a VIM that is a VIM having a user plane function UPF, and is not limited to the illustrated example.
After step 102, either step 103 or 104 is performed.
In step 103, the nfvo matches the preset attribute information required for deploying the VNF entity with the acquired attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs.
In some embodiments, selecting a target VIM comprises: the NFVO matches one or more items of preset capability attribute information, preset position attribute information and preset use attribute information required by the VNF entity with corresponding attribute information in the acquired capability attribute information, position attribute information and use attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs. And selecting a target VIM for deploying the VNF entity according to preset attribute information required by the VNF entity to be deployed and attribute information of each VIM managed by the VNFM, so that the VIM meeting the deployment requirement of the VNF entity can be selected, and the VNF entity can be deployed on the target VIM.
And if only one item of preset attribute information required for deploying the VNF entity exists, matching the preset attribute information required for deploying the VNF entity with the attribute information corresponding to each VIM managed by the VNFM, and selecting the target VIM for deploying the VNF entity. For example, the NFVO matches preset capability attribute information required for deploying the VNF entity with the acquired capability attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs. For another example, the NFVO matches the preset location attribute information required for deploying the VNF entity with the acquired location attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs. For another example, the NFVO matches the preset use attribute information required for deploying the VNF entity with the obtained use attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs.
In the above embodiment, the target VIM is selected according to a certain preset attribute information required for deploying the VNF entity, and the VIM meeting the deployment requirement can be selected, thereby implementing the deployment of the VNF entity.
And if the preset attribute information required for deploying the VNF entity comprises a plurality of items, matching the plurality of items of preset attribute information required for deploying the VNF entity with the attribute information corresponding to each VIM managed by the VNFM, and selecting the target VIM for deploying the VNF entity.
For example, if the preset attribute information required for deploying the VNF entity includes preset capability attribute information and preset location attribute information of the VIM, the NFVO matches the preset capability attribute information and the preset location attribute information required for deploying the VNF entity with the acquired capability attribute information and location attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs. For another example, if the preset attribute information required for deploying the VNF entity includes preset capability attribute information and preset usage attribute information of the VIMs, the NFVO matches the preset capability attribute information and the preset usage attribute information required for deploying the VNF entity with the acquired capability attribute information and usage attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs. For another example, if the preset attribute information required for deploying the VNF entity includes preset location attribute information and preset usage attribute information of the VIM, the NFVO matches the preset location attribute information and the preset usage attribute information required for deploying the VNF entity with the acquired location attribute information and usage attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs. For another example, if the preset attribute information required for deploying the VNF entity includes preset capability attribute information, preset location attribute information, and preset usage attribute information of the VIMs, the NFVO matches the preset capability attribute information, the preset location attribute information, and the preset usage attribute information required for deploying the VNF entity with the acquired capability attribute information, location attribute information, and usage attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs.
In the above embodiment, the target VIM is selected according to a plurality of items of preset attribute information required for deploying the VNF entity, and the VIM meeting the requirements for deploying the VNF entity can be selected, so that the VNF entity is deployed.
If the matched VIM is only one VIM, selecting the VIM as a target VIM; if there are multiple VIMs matching, one VIM may be randomly selected as the target VNF, for example.
In step 104, the nfvo matches the preset attribute information required for deploying the VNF entity with the acquired attribute information of each VIM managed by the VNFM, and selects a target VIM from the matched VIMs according to the resource information of each VIM.
The resource information of the VIM comprises one or more of CPU resources, memory resources and hard disk resources. And selecting a target VIM from each matched VIM according to the resource information of each VIM, thereby realizing the efficient utilization of the idle VIM resources.
If the matched VIM is only one VIM, selecting the VIM as a target VIM; if there are multiple matched VIMs, for example, one VIM with the largest free resources (e.g., CPU resources, memory resources, or hard disk resources) may be selected as the target VIM according to the resource information of each VIM.
For example, the VIM with the largest free CPU resource is selected from the matched VIMs as the target VIM, or the VIM with the largest free memory resource is selected as the target VIM, or the VIM with the largest free hard disk resource is selected as the target VIM, so that the VIM meeting the requirement of the VNF entity deployment can be selected, and meanwhile, the efficient utilization of the free VIM resource can be realized.
For another example, according to the resource information required by the VNF entity to be deployed, a VIM whose idle CPU resource matches the resource information required by the VNF entity is selected from the matched VIMs as a target VIM, or a VIM whose idle memory resource matches the resource information required by the VNF entity is selected as a target VIM, or a VIM whose idle hard disk resource matches the resource information required by the VNF entity is selected as a target VIM. The VIM required by the VNF entity can be selected and deployed, and meanwhile, efficient utilization of idle VIM resources can be achieved.
At step 105, nfvo deploys VNF entities on the target VIM.
In the above embodiment, the NFVO sets corresponding attribute information for each VIM in each VIM resource pool managed by each VNFM, and identifies information such as a use attribute, an action attribute, and a location attribute of each VIM. When the VNF entity is deployed, the attribute information of the VIM set by the NFVO is matched with the preset attribute information of the VIM required by the VNF entity to be deployed, and the target VIM can be selected from a plurality of sets of VIM resource pools by a dynamic scheduling method, so that the VIM meeting the deployment requirement of the VNF entity can be selected, and the VNF entity can be deployed on the target VIM. In addition, the target VIM can be selected from the matched VIMs according to the resource information of the VIMs, so that the efficient utilization of the idle VIM resources can be realized.
