By using NFV technology, software and hardware isolation may be implemented for various network devices such as servers, routers, storage devices and switches. By using NFV technology, the above devices can be deployed in a data center, network node, or user home.

That is, NFV technology primarily integrates the hardware resources of various computers on the network that have data processing capabilities, so that these computers can function as devices in a communication network (eg, server, router, Storage device, or switch).

The method for deploying network services in this embodiment of the present application may be used to complete the deployment of network service 01 and similar network services.

FIG. 2 is a flowchart of Embodiment 1 of a method for deploying a network service according to the present application. As shown in FIG. 2, the method may include the following steps.

Step 201: The primary orchestrator obtains a network service instantiation request. The network service instantiation request is used to request the primary orchestrator to instantiate the network service.

The network service instantiation request may carry network instantiation parameters.

Optionally, the network service instantiation request may be sent to the primary orchestrator by another device or entered by the user into the primary orchestrator. Optionally, the device that sends the network service instantiation request to the primary orchestrator may be an OSS or a business support system (BSS).

It should be noted that the instantiation in the embodiments of the present application mainly includes VNF instantiation or NS instantiation.

VNF instantiation means that VNF software is deployed on the corresponding Network Function Virtualization Infrastructure (NFVI). In VNF instantiation, the process of allocating corresponding computation, storage, and network resources to VNFs needs to be completed.

NS instantiation means that the VNFs and virtual links (VLs) included in the NS are individually instantiated. VL refers to a virtual link between VNFs. VL instantiation means that by allocating corresponding network resources, a virtual link between VNFs is established so that network connections and interactions can be performed between VNFs.

In this embodiment of the present application, the primary orchestrator is specifically a network function virtualization orchestrator (NFVO), a network service orchestrator (NSO), or a network service orchestrator (NSO) or an orchestrator. Orchestrator, RO).

Specifically, the secondary orchestrator in this embodiment of the present application may also be NFVO, NSO, or RO.

In a practical application, the primary orchestrator and the secondary orchestrator may form at least the following combinations. The primary orchestrator is specifically a network function virtualization orchestrator, and the secondary orchestrator is specifically a network function virtualization orchestrator. Alternatively, the primary orchestrator is specifically a resource orchestrator, and the secondary orchestrator is specifically a resource orchestrator. Alternatively, the primary orchestrator is specifically a network service orchestrator and the secondary orchestrator is specifically a network service orchestrator. Alternatively, the primary orchestrator is specifically a network function virtualization orchestrator and the secondary orchestrator is specifically a network service orchestrator. Alternatively, the primary orchestrator is specifically a network service orchestrator and the secondary orchestrator is specifically a network function virtualization orchestrator. Alternatively, the primary orchestrator is specifically a network service orchestrator and the secondary orchestrator is specifically a resource orchestrator. Alternatively, the primary orchestrator is specifically a network function virtualization orchestrator, and the secondary orchestrator is specifically a resource orchestrator.

Optionally, the primary orchestrator and secondary orchestrator in this embodiment may not have been assigned a role before the primary orchestrator obtained the network service instantiation request. That is, the network service instantiation request or network service instantiation parameter may include role information, where the first orchestrator is a primary orchestrator of the network service and the second orchestrator is a secondary orchestrator of the network service. Used to indicate an orchestrator. Only after receiving the network service instantiation request, the first orchestrator determines that the first orchestrator is the primary orchestrator for the network service and the second orchestrator is the secondary orchestrator for the network service.

Optionally, for different network services, the orchestrator may have different roles. Optionally, the orchestrator role information may further be included in a Network Service Descriptor (NSD). That is, in the NSD, the two orchestrators to which the NS corresponding to the NSD is to be deployed are deployed, and the role corresponding to each orchestrator is indicated. The network service instantiation request may be sent to the primary orchestrator by another device or triggered by the primary orchestrator according to the operation entered by the operator.

The upload of the NSD and virtualized network function program packages (VNF packages) may first be completed before the network service instantiation request is obtained. After the upload is complete, the primary orchestrator stores information about NSD and VNF packages.

NSD is used to describe network services and may be used by NFVO, NSO or RO to instantiate NS. The NS includes one or more virtualized network functions (VNFs) and virtual links (Virtual-links, VLs). The NSD may refer to the corresponding Virtualized Network Function Descriptor (VNFD) and Virtual Link Descriptor (VLD).

A VNF package is a VNF program package and may include VNFD and software image files. The VNFD has a one-to-one correspondence with the VNF and describes the virtual resource parameters and requirements necessary to implement the VNF. The VNFD is mainly used by a Virtualized Network Function Manager (VNFM) to create a VNF instance and manage the life cycle of the VNF.

Step 202: Obtain network service description information. The network service description information is used to indicate attribute information of the virtualized network function included in the network service.

The network service description information may be the above NSD. And/or it may be the information carried in the network service instantiation request sent to the primary orchestrator, ie network service instantiation parameters.

If the NSD has been previously uploaded to the primary orchestrator, the NSD information can be obtained directly from the primary orchestrator, or if the NSD has not been previously uploaded to the primary orchestrator, the NSD can be another device or operator. It should be noted that may be sent to the primary orchestrator by

Step 203: Determine some virtualized network functions that need to be deployed in the management domain of the primary orchestrator according to the network service description information.

The network service description information may include information describing the domain corresponding to each VNF. That is, according to the network service description information, it can be determined in which orchestrator's management domain each VNF needs to be deployed. Optionally, in this embodiment of the present application, the plurality of VNFs included in the NS described in the network service description information needs to be respectively deployed in at least two domains. Some VNFs may be deployed in the domain corresponding to the primary orchestrator and other VNFs may be deployed in the domain corresponding to the secondary orchestrator. Optionally, the plurality of VNFs included in the NS described in the network service description information may be deployed only in the domain corresponding to the secondary orchestrator.

Step 204: Instantiate some virtualized network functions.

Some virtualized network functions that need to be deployed in the primary orchestrator's administrative domain can be instantiated directly by the primary orchestrator. For other virtualized network functions that need to be deployed in the secondary orchestrator's administrative domain, the primary orchestrator may inform the secondary orchestrator of relevant information, and the secondary orchestrator may Virtualized network functionality may be deployed. The virtualized network function deployed by the secondary orchestrator may be defined as the first virtualized network function and the virtualized network function deployed by the primary orchestrator may be defined as the second virtualized network function.

The relevant information may include the ID of the primary orchestrator or the ID of the administrative domain of the primary orchestrator. Optionally, the pertinent information further includes the NSD ID, the VNFD IDs corresponding to the VNFs that need to be instantiated by the secondary orchestrator, the IDs of the NS instances that contain these VNFs, and other related VNF deployments. And constraints. This information may be sent by the primary orchestrator individually to the secondary orchestrator, or it may be retained in the instantiation request message when the primary orchestrator sends a VNF instantiation request to the secondary orchestrator. obtain.

Step 205: Determine other virtualized network functions that need to be deployed in the management domain of the secondary orchestrator according to the network service description information.

Step 206: Send a VNF instantiation request to the secondary orchestrator, and the VNF instantiation request is used to request the secondary orchestrator to instantiate another virtualized network function.

The VNF instantiation request includes the ID of the primary orchestrator or the ID of the management domain of the primary orchestrator. Optionally, the VNF instantiation request further includes an NSD ID, a VNFD ID corresponding to the VNF that needs to be instantiated by the secondary orchestrator, an NS instance that includes the VNF that needs to be instantiated by the secondary orchestrator. ID, or another constraint related to VNF deployment. The primary orchestrator and the secondary orchestrator each manage different domains.

In summary, in this embodiment, some virtualized network functions for which the network service description information needs to be obtained and deployed in the management domain of the primary orchestrator are determined according to the network service description information, and some of these virtual network functions are determined. Other virtualized network functions that need to be instantiated and deployed in the administrative domain of the secondary orchestrator are determined according to the network service description information and the VNF service instantiation request is sent to the secondary orchestrator. Sent to. Therefore, cross-domain deployment of NS can be implemented through information exchange between the primary and secondary orchestrator.

It should be noted that in a practical application, the secondary orchestrator may instantiate other virtualized network functions after the primary orchestrator sends a VNF instantiation request to the secondary orchestrator. After instantiating the other virtualized network function, the secondary orchestrator may send instantiation completion notification information to the primary orchestrator. Correspondingly, the primary orchestrator may further obtain the instantiation completion notification information fed back by the secondary orchestrator, and according to the instantiation completion notification information, the network function virtualization instance catalog (NFV Instances catalog) and the network function may be acquired. The Virtualization Infrastructure Resource Catalog (NFVI resources catalog) may be updated. The network function virtualization instance catalog is mainly used for recording information related to the instantiated NS instance and VNF instance, and the network function virtualization infrastructure resource catalog is mainly occupied by the instantiated VNF. Used to record information about virtual resources that are present.

In an actual application, when the secondary orchestrator needs to perform scaling on the virtual resources used by the VNFs in the administrative domain, the secondary orchestrator is the primary orchestrator. It should be further noted that scaling may be applied for. After approval or acknowledgment by the primary orchestrator, the secondary orchestrator performs scaling on the VNF. Scaling includes upscaling and downscaling. Upscaling means increasing resources and downscaling means reducing resources. In the process of performing scaling for VNFs in the administrative domain that the secondary orchestrator is responsible for, the primary orchestrator obtains the scaling request sent by the secondary orchestrator, where the scaling request is , A step used to request other instantiated virtualized network functions to perform scaling, a step deciding to allow the scaling request, and a scaling request acknowledgment message. And transmitting to the next orchestrator.

In the above step, after getting the scaling request sent by the secondary orchestrator, the primary orchestrator decides whether or not to allow the scaling request according to the policy, and confirms the scaling request if the scaling request is allowed. A response message may be sent to the secondary orchestrator, or a scaling request reject message may be sent to the secondary orchestrator if the scaling request was not granted.

In a practical application, the secondary orchestrator performs another lifecycle management operation, such as software update and upgrade, instance termination, or instance modification, on the instantiated VNF in the administrative domain that the secondary orchestrator is responsible for. It should be further noted that the secondary orchestrator needs to apply for approval from the primary orchestrator when needed. The secondary orchestrator may apply to the primary orchestrator each time the secondary orchestrator performs a VNF lifecycle management operation, or the primary orchestrator may send a policy to the secondary orchestrator. , The secondary orchestrator may perform the associated VNF lifecycle management operations according to the policy.

Each time after performing a VNF life cycle management operation, the secondary orchestrator needs to send a VNF life cycle change notification to the primary orchestrator.

Step 401: The primary orchestrator obtains a network service instantiation request, the network service instantiation request is used to request the primary orchestrator to instantiate the network service, and the network service is sent to the network service. It includes nested sub-network services and one or more virtualized network functions.

Step 402: Obtain network service description information, and the network service description information is used to describe the attribute information of the virtualized network function and the attribute information of the sub-network service.

In this embodiment, the network service described in the network service description information is specifically a network service in which sub-network services are nested. The sub-network service includes at least one virtualized network function. Network services NS1 are assumed to include VNF1, VNF2, VNF3 and NS2. NS2 includes VNF4 and VNF5. Next, NS2 is a sub-network service nested in NS1.

Step 403: Determine the virtualized network function that needs to be deployed in the management domain of the primary orchestrator according to the network service description information.

According to the above assumptions, if VNF1, VNF2 and VNF3 need to be deployed on the primary orchestrator and NS2 needs to be deployed on the secondary orchestrator, the virtualized network functions are VNF1, VNF2. And VNF3.

The network service description information may include information describing a domain corresponding to each VNF and a domain corresponding to a sub-network service. That is, it can be determined according to the network service description information to which orchestrator's administrative domain each VNF and sub-network service needs to be deployed. In this embodiment, the plurality of VNFs and sub-network services included in the NS described in the network service description information need to be deployed in at least two domains, respectively. The plurality of VNFs may be deployed in the domain corresponding to the primary orchestrator and the subnetwork service may be deployed in the domain corresponding to the secondary orchestrator.

Step 404: Instantiate the virtualized network function.

VNF1, VNF2, and VNF3 may be instantiated by the primary orchestrator because VNF1, VNF2, and VNF3 need to be the primary orchestrator deployed in the administrative domain of the primary orchestrator.

Step 405: Determine the sub-network service that needs to be deployed to the secondary orchestrator according to the network service description information.

A sub-network service may be a network service that is nested in a network service and needs to be a secondary orchestrator deployed in the administrative domain of the secondary orchestrator. In the above assumptions, the sub-network service may be NS2.

Step 406: Send a subnetwork service instantiation request to the secondary orchestrator, and the subnetwork service instantiation request is used to request the secondary orchestrator to instantiate the subnetwork service.

The primary orchestrator and the secondary orchestrator each manage different domains.

After receiving the sub-network service instantiation request, the secondary orchestrator determines the NSD information corresponding to the sub-network service in the sub-network service instantiation request or the network service instantiation held in the sub-network service instantiation request. The VNFs and VLs included in the sub-network service may be determined according to the parameters, and then each VNF and VL is instantiated according to the descriptive information about the VNFs and VLs.

The network service instantiation request includes the ID of the primary orchestrator, the ID of the administrative domain of the primary orchestrator, or the NSD ID of the sub-network service that needs to be instantiated by the secondary orchestrator. Optionally, the network service instantiation request may further include the NSD ID or NS instance ID of the network service to which the sub-network service belongs, or another constraint related to the deployment of the sub-network service.

In summary, in this embodiment, the primary orchestrator needs to obtain the network service instantiation request, obtain the network service description information, and deploy to the management domain of the primary orchestrator according to the network service description information. The virtualized network function, instantiate the virtualized network function, determine the subnetwork service that needs to be deployed in the administrative domain of the secondary orchestrator according to the network service description information, and request the subnetwork service instantiation request. Send to the next Orchestrator. Therefore, cross-domain deployment of network services can be implemented through the exchange of information between the primary and secondary orchestrator.

It should be noted that in this embodiment, the secondary orchestrator may deploy sub-network services included in the network service.

In practical application, in the process of network service cross-domain deployment, some other technical means are further added so that the process of network service cross-domain deployment matches the existing process of network service deployment. It should be further noted that the gain is obtained. See FIG. 5 for details.

FIG. 5 is a signaling diagram of Embodiment 3 of a method for deploying a network service according to the present application. As shown in FIG. 5, the method may include the following steps.

Step 501: Complete on-board of network service descriptor (NSD) and virtualized network function program package (VNF package).

Can be onboard.

Step 502: The primary orchestrator receives the NS instantiation request.

The NS instantiation request may include instruction information indicating that the NS needs to be deployed across multiple domains, and may further include NS role information. The role information can be used to inform the orchestrator receiving the instantiation request that the orchestrator is the primary orchestrator, and also provide the orchestrator with information such as the identifier of the secondary orchestrator. You can be notified.

NS role information may alternatively be described in the NSD.

When the NS is instantiated, the NSD ID is used to indicate the corresponding NSD. The VNFD ID is used to indicate the VNFD that needs to be used to instantiate the VNF. The NS instance ID is used to indicate the NS instance to which the VNF instance belongs. The primary orchestrator sends the above information to the secondary orchestrator. The secondary orchestrator may obtain the VNFD according to the VNFD ID, then instantiate the VNF based on the VNFD, and further search the connection relationship between the corresponding VNFD ID and the corresponding VNF according to the NSD ID. Once this is done, it performs instantiation and lifecycle management for the VNF.

Step 508: The secondary orchestrator verifies the validity and correctness of the VNF instantiation request sent by the primary orchestrator.

The verification can be performed in the existing manner. If the NS instantiation request is valid and valid, step 509 is performed.

Step 510a: The primary orchestrator connects the VNF in the administrative domain of the primary orchestrator to the network.

Step 510b: The secondary orchestrator connects the VNF in the administrative domain of the secondary orchestrator to the network.

Step 511: The secondary orchestrator sends a VNF instantiation completion confirmation response message to the primary orchestrator.

Step 512: The primary orchestrator updates the primary orchestrator's NFV instance catalog and NFVI resource catalog.

Step 513: The primary orchestrator sends an NS instantiation completion confirmation response message to the sender.
