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

  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 comprise 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 a network service.

  The network service instantiation request may hold network instantiation parameters.

  Optionally, the network service instantiation request can be sent by another device to the primary orchestrator 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 instantiation in the present embodiment 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 assigning corresponding computation, storage, and network resources to VNF needs to be completed.

  NS instantiation means that VNFs and virtual links (VL) included in NS are instantiated individually. 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 (Resource Service Orchestrator, NSor), Orchestrator, RO).

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

  In practical applications, the primary or 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 or secondary orchestrator in this embodiment may not have been assigned a role before the primary orchestrator obtains the network service instantiation request. That is, the network service instantiation request or the network service instantiation parameter may include role information, where the first orchestrator is the primary orchestrator of the network service and the second orchestrator is the secondary of the network service. Used to indicate that it is 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, in 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, NS corresponding to the NSD is deployed in a domain managed by which two orchestrators, and a role corresponding to each orchestrator is indicated. The network service instantiation request may be sent by another device to the primary orchestrator or may be triggered by the primary orchestrator according to the operation entered by the operator.

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

  NSD is used to describe network services and can be used by NFVO, NSO or RO to instantiate NS. The NS includes one or a plurality of virtualized network functions (Virtualized Network Function, VNF) and virtual links (Virtual-link, VL). The NSD may refer to the corresponding virtualized network function descriptor (VNFD) and virtual link descriptor (Virtual-link Descriptor, VLD).

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

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

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

  If the NSD is pre-uploaded to the primary orchestrator, the NSD information can be obtained directly from the primary orchestrator, or if the NSD is not pre-uploaded to the primary orchestrator, the NSD can be another device or operator Note that can be sent to the primary orchestrator.

  Step 203: Determine a number of virtual 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 a domain corresponding to each VNF. That is, according to the network service description information, it can be determined to 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 need to be deployed in at least two domains, respectively. Some VNFs can be deployed in the domain corresponding to the primary orchestrator and other VNFs can 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 can 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 administrative domain of the primary orchestrator can be instantiated directly by the primary orchestrator. For other virtualized network functions that need to be deployed in the secondary orchestrator administrative domain, the primary orchestrator can notify the secondary orchestrator of relevant information, and the secondary orchestrator can Virtual network functions can be deployed. The virtualized network function deployed by the secondary orchestrator can be defined as the first virtualized network function, and the virtualized network function deployed by the primary orchestrator can be defined as the second virtualized network function.

  The related information may include the ID of the primary orchestrator or the management domain ID of the primary orchestrator. Optionally, the related information further includes the NSD ID, the VNFD ID corresponding to the VNF that needs to be instantiated by the secondary orchestrator, the ID of the NS instance that contains these VNFs, and the other associated with the VNF deployment. Constraints. These information can be sent individually by the primary orchestrator to the secondary orchestrator, or 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 other virtualization network functions.

  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 NS instance including an NSD ID, a VNFD ID corresponding to the VNF that needs to be instantiated by the secondary orchestrator, and a VNF that needs to be instantiated by the secondary orchestrator. Or other constraints related to VNF deployment. Each primary or secondary orchestrator manages a different domain.

  In summary, in this embodiment, the network service description information is obtained and several virtualized network functions that need to be deployed in the management domain of the primary orchestrator are determined according to the network service description information. The virtualized network function is instantiated and other virtualized network functions that need to be deployed in the secondary orchestrator's management domain are determined according to the network service description information, and the VNF service instantiation request is sent to the secondary orchestrator. Sent to. Thus, NS cross-domain deployment can be implemented through information exchange between primary and secondary orchestrators.

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

  In actual application, the secondary orchestrator is the primary orchestrator when coordination (scaling) needs to be performed on the virtual resources used by the VNF in the management domain served by the secondary orchestrator. It should be further noted that you can apply for scaling. 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 decreasing resources. In the process of performing scaling on the VNF in the management domain served by the secondary orchestrator, the primary orchestrator is the stage where the primary orchestrator obtains the scaling request sent by the secondary orchestrator, where the scaling request is Used to request other instantiated virtualization network functions to perform scaling, a stage to decide to allow the scaling request, and a scaling request acknowledgment message. Transmitting to the next orchestrator.

  In the above stage, after getting the scaling request sent by the secondary orchestrator, the primary orchestrator decides whether 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 is not granted.

  In actual 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 management domain served by the secondary orchestrator. It should be further noted that the secondary orchestrator needs to apply for approval from the primary orchestrator when needed. The secondary orchestrator can apply to the primary orchestrator every time the secondary orchestrator performs a VNF lifecycle management operation, or the primary orchestrator can send a policy to the secondary orchestrator. The secondary orchestrator may perform related VNF lifecycle management operations according to policy.

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

FIG. 3B is a schematic architectural diagram of yet another NFV system according to the present application. In comparison, the difference that distinguishes the system architecture shown in FIGS. 3A and 3B from the system architecture shown in FIG. 1 is that the network function virtualization orchestrator is connected to a network service orchestrator (NSO) and a resource orchestrator. (Resource Orchestrator, RO) is divided into two modules. The specific examples in FIGS. 1 and 3A are used for illustration. That is, the network function virtualization orchestrator 101 is divided into a network service orchestrator 303 and a resource orchestrator 301, and the network function virtualization orchestrator 102 is divided into a network service orchestrator 304 and a resource orchestrator 302.

  The network service orchestrator is responsible for life cycle management for network services, and the resource orchestrator is responsible for virtual resource management.

  In FIG. 3A, there is a communication link between the resource orchestrator 301 and the resource orchestrator 302. In FIG. 3B, there is a communication link between the network service orchestrator 303 and the network service orchestrator 304.

  As used herein, the primary or secondary orchestrator is a network function virtualization orchestrator, or the primary or secondary orchestrator is a network service orchestrator, or the primary or secondary orchestrator. It should be noted that when the lator is a resource orchestrator, the method for deploying network services in the embodiments of the present application may be performed or used.

  FIG. 4 is a flowchart of Embodiment 2 of a method for deploying a network service according to the present application. As shown in FIG. 4, the method may comprise the following steps.

  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 Includes nested subnetwork 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 attribute information of a virtual network function and attribute information of a 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 virtual network function. Assume that the network service NS1 includes VNF1, VNF2, VNF3, and NS2. NS2 includes VNF4 and VNF5. Next, NS2 is a sub-network service nested in NS1.

  Step 403: Determine a 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 to the primary orchestrator and NS2 needs to be deployed to the secondary orchestrator, the virtualized network functions will be VNF1, VNF2 And VNF3.

  The network service description information may include information describing a domain corresponding to each VNF and a domain corresponding to the sub-network service. That is, according to the network service description information, it can be determined to which orchestrator's management domain each VNF and sub-network service needs to be deployed. In this embodiment, a 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. Multiple VNFs can be deployed in the domain corresponding to the primary orchestrator, and sub-network services can be deployed in the domain corresponding to the secondary orchestrator.

  Step 404: Instantiate a virtualized network function.

  Since VNF1, VNF2, and VNF3 need to be primary orchestrators deployed in the administrative domain of the primary orchestrator, VNF1, VNF2 and VNF3 can be instantiated by the primary orchestrator.

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

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

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

  Each primary or secondary orchestrator manages a different domain.

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

  The network service instantiation request includes the ID of the primary orchestrator, the ID of the primary orchestrator's management domain, 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 subnetwork service belongs, or another constraint related to the deployment of the subnetwork service.

  In summary, in this embodiment, the primary orchestrator acquires the network service instantiation request, acquires the network service description information, and the virtual that needs to be deployed in the management domain of the primary orchestrator according to the network service description information. The virtual network function is determined, the virtual network function is instantiated, the sub network service that needs to be deployed in the management domain of the secondary orchestrator is determined according to the network service description information, and the sub network service instantiation request is Send to the next orchestrator. Thus, cross-domain deployment of network services can be implemented through the exchange of information between primary and secondary orchestrators.

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

  In practical application, the network service cross-domain deployment process further adds some other technical means so that the network service cross-domain deployment process matches the existing network service deployment process.

The NS instance ID is used to indicate the NS instance to which the VNF instance belongs. The primary orchestrator transmits the above information to the secondary orchestrator. The secondary orchestrator can obtain the VNFD according to the VNFD ID, then instantiates the VNF based on the VNFD, and further retrieves the connection relationship between the corresponding VNFD ID and the corresponding VNF according to the NSD ID. Thus, instantiation and lifecycle management is performed on the VNF.

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

  Verification can be performed in an existing manner. If the NS instantiation request is valid and valid, step 509 is executed.
