一种生命周期管理方法及管理单元Life cycle management method and management unit

技术领域Technical field

本发明涉及通信技术领域，尤其涉及一种生命周期管理方法及管理单元。The present invention relates to the field of communications technologies, and in particular, to a lifecycle management method and a management unit.

背景技术Background technique

随着云计算技术的不断成熟，信息技术(Information Techonology，IT)与通讯技术(Communication Techonology，CT)相互渗透融合，CT运营商为应对未来竞争挑战，顺应当前虚拟化、云计算的技术发展趋势，提出了信息与通讯技术(Information and Communications Technology，ICT)领域的网络功能虚拟化(Network Function Virtualization，NFV)技术。With the continuous maturity of cloud computing technology, Information Technology (IT) and Communication Technology (CT) are mutually infiltrated and integrated, and CT operators respond to the current competitive challenges and adapt to the current development trend of virtualization and cloud computing. Network Function Virtualization (NFV) technology in the field of Information and Communications Technology (ICT) was proposed.

NFV技术基于海量的、归一化的服务器和交换机，通过软件实现多种网络功能(例如：虚拟运营、虚拟广域网、虚拟应用接入路由器等功能)，从而降低成本，加速业务部署、资源弹性伸缩，构建创新生态链。NFV技术中，一台计算机被虚拟为多台虚拟逻辑计算机，即虚拟机(Virtual Machine，VM)。虚拟机一般使用连接机框内交换机或者架顶交换机的服务器物理网口、虚拟网卡以及虚拟交换机，与服务器外部进行数据通信。NFV technology is based on massive and normalized servers and switches, and implements various network functions (such as virtual operations, virtual wide area networks, and virtual application access routers) through software to reduce costs and accelerate service deployment and resource flexibility. , build an innovative ecological chain. In NFV technology, a computer is virtualized into multiple virtual logical computers, namely virtual machines (VMs). A virtual machine generally uses a server physical network port, a virtual network card, and a virtual switch connected to the switch in the chassis or the top switch to perform data communication with the outside of the server.

NFV技术通过借用信息技术(Information Technology，IT)的虚拟化技术，使得许多类型的网络设备可以合并到工业标准中，例如，使得业务、交换、存储等网络设备可以部署在数据中心或者网络节点中。NFV技术将各种网络功能以软件方式实现，并能在工业标准的服务器上运行这些网络功能，还能根据需要对这些网络功能进行迁移、实例化、以及重新部署等等，并且不需要安装新的设备。即通过NFV技术可以产生虚拟网络功能(Virtualized Network Function，VNF)。多个VNF之间可以实现网络服务(Network Service，NS)。虚拟网络功能描述符(Virtualized Network Function Descriptor，VNFD)是VNF部署和维护行为的描述模板。网络服务描述符(Network Service Descriptor，NSD)是描述NS的部署和维护的模板，包括服务拓扑(VNF的各个组成部分及相互间的关系、虚拟链路、VNF转发图)以及网络服务的各项特性(例如服务等级协议、NS实例的运行及生命周期管理所具备的相关特性)。NSD包括VNFD、VNF转发图描述符、虚拟链接描述符、物理网络功能描述符等描述符。By borrowing the information technology (Information Technology, IT) virtualization technology, NFV technology enables many types of network devices to be incorporated into industry standards. For example, network devices such as services, switching, and storage can be deployed in data centers or network nodes. . NFV technology implements various network functions in software and can run these network functions on industry-standard servers. It can also migrate, instantiate, redeploy, etc. these network functions as needed, and does not need to install new ones. device of. That is, the virtualized network function (VNF) can be generated by the NFV technology. Network Service (NS) can be implemented between multiple VNFs. The Virtualized Network Function Descriptor (VNFD) is a description template for VNF deployment and maintenance behavior. The Network Service Descriptor (NSD) is a template for describing the deployment and maintenance of the NS, including the service topology (the various components of the VNF and the relationship between them, the virtual link, the VNF forwarding map), and the various network services. Features (such as service level agreements, NS instance operations, and related features of lifecycle management). The NSD includes descriptors such as VNFD, VNF forwarding map descriptors, virtual link descriptors, and physical network function descriptors.

目前，网络功能虚拟化调度(NFV Orchestrator，NFVO)单元在实现NS的生命周期管理时，往往需要经历多个参数的条件过滤流程、额外查找流程及策略性参数筛选流程等，来获取合适的实例。这使得生命周期管理过程较为复杂、处理效率低。At present, the NFV Orchestrator (NFVO) unit often needs to undergo a conditional filtering process with multiple parameters and an additional search process when implementing NS lifecycle management. Strategic parameter screening process, etc., to obtain suitable examples. This makes the lifecycle management process more complicated and less efficient.

Increase the autonomy of the first management unit; or, the first management unit may send a selection request to the second management unit, the selection request is used to instruct the second management unit to select an equal number of VNF instances as the preset threshold, so that the first management The unit performs lifecycle management on the target NS according to the selected VNF instance.

下面将基于上面所述的本发明实施例涉及的共性方面，对本发明实施例进一步详细说明。The embodiments of the present invention will be further described in detail below based on the common aspects of the embodiments of the present invention described above.

目前，厂商配置的NSD包括VNFD、虚拟网络功能转发图描述符(Virtualized Network Function Forwarding Graph Descriptor，VNFFGD)、虚拟链接描述符(Virtualized Link Descriptor，VLD)、物理网络功能描述符(Physics Network Function Descriptor，PNFD)等描述符。以NS的实例化为例，NS的生命周期管理可以通过新建VNF实例来实现，具体过程为：NFVO接收OSS/BSS发送的针对目标NS的实例化请求，该实例化请求包括目标NS的目标NSD ID，NFVO根据目标NSD ID查找目标NSD，该目标NSD包括多组实例需求信息，多组实例需求信息中每组实例需求信息包括VNFD、VNFFGD、VLD、PNFD等描述符，NFVO根据多组实例需求信息向VNFM发送实例化请求，由VNFM根据多组实例需求信息实例化出多个VNF实例，这些VNF实例存在于图1所示的网络架构中。Currently, vendor-configured NSDs include VNFD, Virtualized Network Function Forwarding Graph Descriptor (VNFFGD), Virtualized Link Descriptor (VLD), and Physical Network Function Descriptor (Physics Network Function Descriptor, PNFD) and other descriptors. Taking the instantiation of NS as an example, the lifecycle management of the NS can be implemented by creating a VNF instance. The specific process is: the NFVO receives an instantiation request for the target NS sent by the OSS/BSS, and the instantiation request includes the target NSD of the target NS. ID, NFVO finds the target NSD according to the target NSD ID. The target NSD includes multiple sets of instance requirement information, and each set of instance requirement information in the plurality of sets of instance requirement information includes descriptors such as VNFD, VNFFGD, VLD, PNFD, etc., and NFVO according to multiple sets of instance requirements The information sends an instantiation request to the VNFM, and the VNFM instantiates a plurality of VNF instances according to the plurality of sets of instance requirement information. The VNF instances exist in the network architecture shown in FIG.

图1所示的网络架构中除包括VNF实例外，还包括其它实例，例如，虚拟链路(Virtualized Link，VL)实例等，这些实例可以长期稳定地存在于网络架构中，并且这些实例中的每个实例可能被多个NS的生命周期管理调用。例如，网络架构中的移动性管理实体(Mobility Management Entity，MME)可以被多个服务网关(Serving-GateWay，S-GW)调用。 In addition to the VNF instance, the network architecture shown in FIG. 1 includes other examples, such as virtualized link (VL) instances, etc., which can exist stably in the network architecture for a long time, and in these examples. Each instance may be called by the lifecycle management of multiple NSs. For example, a Mobility Management Entity (MME) in a network architecture may be invoked by multiple Serving-GateWays (S-GWs).

由于网络架构中存在一些实例，因此NS的生命周期管理还可以通过查找NS实例化所需的实例来实现，具体过程为：NFVO接收OSS/BSS发送的针对目标NS的实例化请求，该实例化请求包括目标NS的目标NSD ID，NFVO根据目标NSD ID查找目标NSD，该目标NSD包括多组实例需求信息，多组实例需求信息中每组实例需求信息包括VNFD、VNFFGD、VLD、PNFD等描述符，NFVO根据多组实例需求信息在网络架构中查找与实例需求信息相匹配的VNF实例，从而实现目标NS的实例化。在通过VNFD等描述符来查找匹配的实例的过程中，可能查找到多个符合要求的实例，但是生命周期管理可能只需要与描述符相匹配的一个实例即可，因此需要通过多个参数进行条件过滤、额外查找流程以及策略性参数筛选从多个实例中选择一个实例，导致生命周期管理的过程复杂，耗时较长，影响处理效率。Because there are some instances in the network architecture, the lifecycle management of the NS can also be implemented by searching for the required instance of the NS instantiation. The specific process is: the NFVO receives the instantiation request for the target NS sent by the OSS/BSS, and the instantiation is performed. The request includes the target NSD ID of the target NS, and the NFVO searches for the target NSD according to the target NSD ID, where the target NSD includes multiple sets of instance requirement information, and each set of instance requirement information in the plurality of sets of instance requirement information includes descriptors such as VNFD, VNFFGD, VLD, and PNFD. The NFVO finds the VNF instance matching the instance requirement information in the network architecture according to the multiple sets of instance requirement information, thereby realizing the instantiation of the target NS. In the process of finding matching instances through descriptors such as VNFD, it may be possible to find multiple instances that meet the requirements, but lifecycle management may only need one instance that matches the descriptor, so it needs to be performed by multiple parameters. Conditional filtering, additional discovery processes, and strategic parameter filtering select one instance from multiple instances, resulting in a complex lifecycle management process that takes a long time and affects processing efficiency.

基于此，本发明实施例提供一种生命周期管理方法，和基于这个方法的第一管理单元、第二管理单元和***，以精简生命周期管理过程，提高处理效率。在该方法中，第一管理单元从第二管理单元接收目标NS的生命周期管理请求，该生命周期管理请求包括目标NSD ID；第一管理单元根据目标NSD ID查找目标NSD，该目标NSD包括实例标识，或该目标NSD包括标识和VNFD ID，该实例标识和/或VNFD ID用于确定目标NS的生命周期管理所需的实例；第一管理单元根据实例标识和/或VNFD ID对目标NS进行生命周期管理。本发明实施例中，目标NSD包括的实例标识和/或VNFD ID用于确定目标NS的生命周期管理所需的实例，第一管理单元能够根据该实例标识和/或VNFD ID实现对目标NS的生命周期管理，从而既充分利用网络架构中的实例，又能精简生命周期管理过程，提高处理效率。其中，对目标NS进行生命周期管理可以为对目标NS进行实例化，即实例化出目标NS所需的一个或多个VNF实例；对目标NS进行生命周期管理也可以为对目标NS进行更新。需要说明的是，上述第一管理单元为接收生命周期管理请求的一端，例如可以为图1中的NFVO单元；上述第二管理单元为发送生命周期管理请求的一端，例如可以为图1中的OSS/BSS。Based on this, an embodiment of the present invention provides a lifecycle management method, and a first management unit, a second management unit, and a system based on the method, to streamline the lifecycle management process and improve processing efficiency. In the method, the first management unit receives a lifecycle management request of the target NS from the second management unit, the lifecycle management request includes a target NSD ID; the first management unit searches for the target NSD according to the target NSD ID, the target NSD includes an instance The identifier, or the target NSD includes an identifier and a VNFD ID, the instance identifier and/or the VNFD ID is used to determine an instance required for lifecycle management of the target NS; the first management unit performs the target NS according to the instance identifier and/or the VNFD ID Lifecycle management. In the embodiment of the present invention, the instance identifier and/or the VNFD ID included in the target NSD is used to determine an instance required for lifecycle management of the target NS, and the first management unit can implement the target NS according to the instance identifier and/or the VNFD ID. Lifecycle management, which not only makes full use of the examples in the network architecture, but also streamlines the lifecycle management process and improves processing efficiency. The lifecycle management of the target NS may be to instantiate the target NS, that is, to instantiate one or more VNF instances required by the target NS; and to perform lifecycle management on the target NS may also update the target NS. It should be noted that the first management unit is one end that receives the lifecycle management request, and may be, for example, the NFVO unit in FIG. 1; the second management unit is one end that sends a lifecycle management request, and may be, for example, the one in FIG. OSS/BSS.

本发明实施例的方案可以应用于图1所示的基于NFV的网络架构，通过本发明实施例的方案可以精简生命周期管理过程，提高处理效率。The solution of the embodiment of the present invention can be applied to the NFV-based network architecture shown in FIG. 1. The solution of the embodiment of the present invention can simplify the lifecycle management process and improve processing efficiency.

下面结合附图2～图4对本发明实施例提供的方案进行详细说明。The solution provided by the embodiment of the present invention is described in detail below with reference to FIG. 2 to FIG.

图2示出了本发明实施例提供的一种生命周期管理方法。图2所示的方法可以应用于图1所示的网络架构，其中，第一管理单元可以为NFVO单元，第二管理单元可以为OSS/BSS。FIG. 2 shows a lifecycle management method provided by an embodiment of the present invention. The method shown in Figure 2 It can be applied to the network architecture shown in FIG. 1, wherein the first management unit can be an NFVO unit, and the second management unit can be an OSS/BSS.

在201部分，第二管理单元确定目标NS、目标NSD和目标NSD ID。In section 201, the second management unit determines the target NS, the target NSD, and the target NSD ID.

其中，上述目标NS为待进行生命周期管理的NS，上述目标NSD和目标NSD ID分别为目标NS的NSD和NSD ID。The target NS is an NS to be subjected to lifecycle management, and the target NSD and the target NSD ID are respectively an NSD and an NSD ID of the target NS.

在一个示例中，第二管理单元可以根据实际需要确定目标NS、目标NSD和目标NSD ID。目标NSD用于描述目标NS的部署和维护，目标NSD ID为目标NSD的标识，用于区分目标NSD与其它NSD。每个NSD唯一对应一个NSD ID，根据NSD ID可以查找对应的NSD。In one example, the second management unit may determine the target NS, the target NSD, and the target NSD ID according to actual needs. The target NSD is used to describe the deployment and maintenance of the target NS. The target NSD ID is the identifier of the target NSD, which is used to distinguish the target NSD from other NSDs. Each NSD uniquely corresponds to an NSD ID, and the corresponding NSD can be found according to the NSD ID.

在一个示例中，第二管理单元在确定目标NS时，可以确定目标NSD所包括的内容。在本发明实施例中，目标NSD可以包括实例标识，实例标识可用于确定目标NS的生命周期管理所需的实例。实例标识可以包括以下至少一种：VNF实例标识、物理网络功能(Physics Network Function，PNF)实例标识、虚拟网络功能转发图(Virtualized Network Function Forwarding Graph，VNFFG)实例标识、网络功能路径(Network Function Path，NFP)实例标识、虚拟链接(Virtualized Link，VL)实例标识、NS实例标识或服务接入点(Service Accessing Point，SAP)实例标识。其中，每种实例标识用于标识一种实例，例如，VNF实例标识用于标识VNF实例，每个VNF实例对应不同的VNF实例标识。换言之，VNF实例标识即VNF实例ID，PNF实例标识即PNF实例ID，VNFFG实例标识即VNFFG实例ID，VL实例标识即VL实例ID，NS实例标识即NS实例ID，SAP实例标识即SAP实例ID。可选的，上述实例标识可以为一组或多组实例标识，其中，一组实例标识可以包括VNF实例标识、PNF实例标识、VNFFG实例标识、NFP实例标识、VL实例标识、NS实例标识或SAP实例标识中的至少一种。可以理解的是，一组实例标识用于指示一个VNF实例以及该VNF实例的链路接口实例，例如转发图实例、虚拟链接实例、接入点实例等。某一组实例标识的具体内容可由网络服务的规划设计工程师或第二管理单元的网络管理员选定并录入。In one example, the second management unit may determine the content included in the target NSD when determining the target NS. In an embodiment of the present invention, the target NSD may include an instance identifier that may be used to determine an instance required for lifecycle management of the target NS. The instance identifier may include at least one of the following: a VNF instance identifier, a physical network function (PNF) instance identifier, a virtualized network function forwarding graph (VNFFG) instance identifier, and a network function path (Network Function Path) , NFP) instance ID, virtual link (VL) instance ID, NS instance ID, or Service Access Point (SAP) instance ID. Each instance identifier is used to identify an instance. For example, the VNF instance identifier is used to identify the VNF instance, and each VNF instance corresponds to a different VNF instance identifier. In other words, the VNF instance identifier is the VNF instance ID, the PNF instance identifier is the PNF instance ID, the VNFFG instance identifier is the VNFFG instance ID, the VL instance identifier is the VL instance ID, the NS instance identifier is the NS instance ID, and the SAP instance identifier is the SAP instance ID. Optionally, the foregoing instance identifier may be one or more sets of instance identifiers, where the set of instance identifiers may include a VNF instance identifier, a PNF instance identifier, a VNFFG instance identifier, an NFP instance identifier, a VL instance identifier, an NS instance identifier, or an SAP. At least one of the instance identifiers. It can be understood that a set of instance identifiers is used to indicate a VNF instance and a link interface instance of the VNF instance, such as a forwarding map instance, a virtual link instance, an access point instance, and the like. The specific content of a certain group of instance identifiers may be selected and entered by the planning design engineer of the network service or the network administrator of the second management unit.

在一个示例中，上述实例标识包括复用指示信息，该复用指示信息用于指示实例标识所标识的实例是否可以被至少两个NS复用。该复用指示信息可以是某个字段，该字段的数值可以指示实例标识所标识的实例是否可以被至少两个NS复用。例如某个VNFFG实例标识包括该字段，该字段指示该VNFFG实例标识所标识的VNFFG实例1可以被至少两个NS复用，那么其它NS在生命周期管理过程可直接调用VNFFG实例1，精简生命周期管理过程。第二管理单元在确定目标NSD所包括的内容时，确定上述每种实例标识是否包含对应的实例可以被至少两个NS复用的字段，该字段可由第二管理单元的网络管理员或网络服务的规划设计工程师录入，第二管理单元对其进行识别即可。In an example, the foregoing instance identifier includes multiplexing indication information, where the multiplexing indication information is used to indicate whether the instance identified by the instance identifier can be multiplexed by at least two NSs. The multiplexing indication information may be a field, and the value of the field may indicate whether the instance identified by the instance identifier can be at least two NS multiplexing. For example, a certain VNFFG instance identifier includes the field, and the field indicates that the VNFFG instance ID identified by the VNFFG instance identifier can be multiplexed by at least two NSs, and the other NS can directly invoke the VNFFG instance 1 in the lifecycle management process to simplify the life cycle. Management process. When determining the content included in the target NSD, the second management unit determines whether each of the instance identifiers includes a field in which the corresponding instance can be multiplexed by at least two NSs, and the field may be served by a network administrator or network service of the second management unit. The planning and design engineer enters and the second management unit identifies it.

在一个示例中，上述实例标识所标识的实例包括复用指示信息，该复用指示信息用于指示实例是否可以被至少两个NS复用。该复用指示信息可以是实例中的某个字段，该字段可以指示实例是否可以被至少两个NS复用。例如，某个VNF实例标识所标识的VNF实例1包括该字段，那么其它NS在生命周期管理过程可直接调用VNF实例1，精简生命周期管理过程。In an example, the instance identified by the example identifier includes multiplexing indication information, and the multiplexing indication information is used to indicate whether an instance can be multiplexed by at least two NSs. The multiplexing indication information may be a certain field in the instance, which may indicate whether the instance can be multiplexed by at least two NSs. For example, if the VNF instance 1 identified by a VNF instance identifier includes the field, the other NS can directly invoke the VNF instance 1 in the lifecycle management process to streamline the lifecycle management process.

在一个示例中，目标NSD可以包括VNFD ID，VNFD ID可用于确定目标NS的生命周期管理所需的实例。In one example, the target NSD can include a VNFD ID that can be used to determine the instances required for lifecycle management of the target NS.

在一个示例中，目标NSD可以包括上述实例标识和上述VNFD ID。在这种情况下，可以先根据实例标识对目标NS进行生命周期管理；在无法根据上述实例标识对目标NS进行生命周期管理的情况下，可根据VNFD ID对目标NS进行生命周期管理。VNFD ID所标识的虚拟网络功能描述符VNFD可以包括复用指示信息，指示VNFD对应的VNF实例是否可以被至少两个NS复用。或者，VNFD ID所标识的VNFD对应的VNF实例包括复用指示信息，该复用指示信息指示VNF实例是否可以被至少两个NS复用。上述目标NS是否包括VNFD ID，以及VNFD是否包括复用指示信息可以由第二管理单元的网络管理员或网络服务的规划设计工程师设定。In one example, the target NSD can include the above instance identification and the VNFD ID described above. In this case, the lifecycle management of the target NS may be performed according to the instance identifier. If the lifecycle management of the target NS cannot be performed according to the foregoing instance identifier, the lifecycle management of the target NS may be performed according to the VNFD ID. The virtual network function descriptor VNFD identified by the VNFD ID may include multiplexing indication information indicating whether the VNF instance corresponding to the VNFD can be multiplexed by at least two NSs. Alternatively, the VNF instance corresponding to the VNFD identified by the VNFD ID includes multiplexing indication information indicating whether the VNF instance can be multiplexed by at least two NSs. Whether the above target NS includes the VNFD ID, and whether the VNFD includes the multiplexing indication information may be set by the network administrator of the second management unit or the planning design engineer of the network service.

在202部分，第二管理单元向第一管理单元发送目标NS的生命周期管理请求，该生命周期管理请求包括目标NSD ID。In section 202, the second management unit sends a lifecycle management request of the target NS to the first management unit, the lifecycle management request including the target NSD ID.

在一个示例中，第二管理单元可以通过第二管理单元与第一管理单元之间的通信接口向第一管理单元发送目标NS的生命周期管理请求，该生命周期管理请求包括目标NSD ID。在本示例中，第二管理单元可以仅在该生命管理请求中携带目标NSD ID，而无需将目标NSD所包括的内容携带在该生命周期管理请求中。如此实施的前提条件是，第一管理单元已将目标NSD上载(onboard)，即第一管理单元已上载目标NSD以及目标NSD所包括的内容。可选的，第一管理单元可以将目标NSD以及目标NSD所包括的内容上载至目录，该目录可以是图1所示网络结构中的VNF服务目录、VNF目录，也可以是图1所示网络结构中的其它目录，在此不做限定。In one example, the second management unit may send a lifecycle management request of the target NS to the first management unit through a communication interface between the second management unit and the first management unit, the lifecycle management request including the target NSD ID. In this example, the second management unit may carry the target NSD ID only in the life management request without carrying the content included in the target NSD in the lifecycle management request. The prerequisite for such implementation is that the first management unit has uploaded the target NSD, that is, the first management unit has uploaded the content included in the target NSD and the target NSD. Optionally, the first management unit may upload the content included in the target NSD and the target NSD to the directory, where the directory may be a VNF service directory, a VNF directory, or a network shown in FIG. 1 in the network structure shown in FIG. Other directories in the structure are not limited herein.

在一个示例中，第一管理单元从第二管理单元接收目标NS的生命周期管理请求之前，还可以从第二管理单元接收目标NSD的上载请求，并上载该目标NSD。可选的，第一管理单元上载目标NSD之前，还可以确定该上载请求有效，例如第一管理单元可以根据上述复用指示信息确定该上载请求有效。其中，第一管理单元上载目标NSD的过程可以参考图3所示的方式，具体实现可参见后面图3部分的介绍。In one example, before the first management unit receives the lifecycle management request of the target NS from the second management unit, the first management unit may also receive an upload request of the target NSD from the second management unit and upload the target NSD. Optionally, before the first management unit uploads the target NSD, the upload request may be determined to be valid. For example, the first management unit may determine, according to the multiplexing indication information, that the upload request is valid. The process of uploading the target NSD by the first management unit may refer to the manner shown in FIG. 3. For specific implementation, refer to the description in the following FIG.

在一个示例中，第一管理单元还可以从第二管理单元接收目标NSD的修改请求，修改请求用于请求第一管理单元修改目标NSD，然后，第一管理单元修改该目标NSD，并上载修改后的目标NSD。可选的，第一管理单元修改目标NSD之前，还可以确定该修改请求有效，例如第一管理单元可以根据上述复用指示信息确定该修改请求有效。其中，第一管理单元修改目标NSD的过程可以参考图4所示的方式，具体实现可参见后面图4部分的介绍。In an example, the first management unit may further receive a modification request of the target NSD from the second management unit, where the modification request is used to request the first management unit to modify the target NSD, and then the first management unit modifies the target NSD and uploads the modification After the target NSD. Optionally, before the first management unit modifies the target NSD, the modification request may be determined to be valid. For example, the first management unit may determine, according to the multiplexing indication information, that the modification request is valid. The process of modifying the target NSD by the first management unit may refer to the manner shown in FIG. 4, and the specific implementation may be referred to the description in the following FIG.

在203部分，第一管理单元根据目标NSD ID查找目标NSD，该目标NSD包括实例标识，或该目标NSD包括实例标识和VNFD ID。In section 203, the first management unit looks up the target NSD according to the target NSD ID, the target NSD includes an instance identifier, or the target NSD includes an instance identifier and a VNFD ID.

在一个示例中，第一管理单元根据上述生命周期管理请求所包括的目标NSD ID查找目标NSD，该目标NSD包括实例标识，或该目标NSD包括实例标识和VNFD ID。该VNFD ID的数量可与实例标识的组数相同，也可以不相同。可选的，第一管理单元根据目标NSD ID在目录中查找目标NSD以及目标NSD所包括的内容。In one example, the first management unit looks up the target NSD according to the target NSD ID included in the lifecycle management request, the target NSD includes an instance identifier, or the target NSD includes an instance identifier and a VNFD ID. The number of VNFD IDs may or may not be the same as the number of groups identified by the instance. Optionally, the first management unit searches the directory for the target NSD and the content included in the target NSD according to the target NSD ID.

在204部分，第一管理单元根据实例标识和/或VNFD ID对目标NS进行生命周期管理。In section 204, the first management unit performs lifecycle management on the target NS based on the instance identification and/or the VNFD ID.

在一个示例中，第一管理单元根据实例标识查找实例，对目标NS进行生命周期管理。上述生命周期管理请求可以为实例化请求或更新请求。In one example, the first management unit performs a lifecycle management on the target NS according to the instance identification lookup instance. The above lifecycle management request may be an instantiation request or an update request.

在一个示例中，若上述生命周期管理请求为实例化请求，则第一管理单元可以确定目标NSD所包括的实例标识是否包括VNF实例标识。可选的，由于实例标识可以为一组或多组实例标识，因此，若实例标识为一组实例标识，则第一管理单元确定该组实例标识是否包括VNF实例标识；若实例标识为多组实例标识，则第一管理单元确定每组实例标识中是否均包括VNF实例标识。In an example, if the lifecycle management request is an instantiation request, the first management unit may determine whether the instance identifier included in the target NSD includes the VNF instance identifier. Optionally, the instance identifier may be one or more sets of instance identifiers. Therefore, if the instance identifier is a set of instance identifiers, the first management unit determines whether the group instance identifier includes the VNF instance identifier; The instance identifier, the first management unit determines whether each group instance identifier includes a VNF instance identifier.

在一种可能的实施方式中，若上述实例标识包括VNF实例标识，则第一管理单元可以查找或获取VNF实例标识对应的VNF实例，并根据获取的VNF实例对目标NS进行实例化。可选的，由于实例标识可以为一组或多组实例标识，因此，若实例标识为一组实例标识，该组实例标识包括VNF实例标识，则第一管理单元查找或获取该VNF实例标识对应的VNF实例；若实例标识为多组实例标识，多组实例标识中每组实例标识均包括VNF实例标识，则第一管理单元分别查找或获取每个VNF实例标识对应的VNF实例，并根据获取的多个VNF实例对目标NS进行实例化。In a possible implementation, if the instance identifier includes the VNF instance identifier, the first management unit may find or obtain the VNF instance corresponding to the VNF instance identifier, and instantiate the target NS according to the obtained VNF instance. Optionally, the instance identifier may be one or more groups of instance identifiers. Therefore, if the instance identifier is a set of instance identifiers, and the group instance identifier includes the VNF instance identifier, the first management unit searches for or obtains the VNF instance identifier. The VNF instance; if the instance identifier is a plurality of sets of instance identifiers, and each of the plurality of sets of instance identifiers includes the VNF instance identifier, the first management unit respectively searches for or obtains the VNF instance corresponding to each VNF instance identifier, and obtains the VNF instance according to the Multiple VNF instances instantiate the target NS.

在另一种可能的实施方式中，若上述实例标识不包括VNF实例标识，则第一管理单元可以根据目标NSD所包括的VNFD ID查找与VNFD ID相匹配的VNF实例。可选的，第一管理单元可以在已存在的VNF实例集合中查找与VNFD ID相匹配的VNF实例，其中，已存在的VNF实例集合即为网络架构中存在的VNF实例集合。可选的，由于实例标识可以为一组或多组实例标识，因此，若实例标识为一组实例标识，该组实例标识不包括VNF实例标识，则第一管理单元根据目标NSD所包括的VNFD ID查找与该VNFD ID相匹配的VNF实例；若实例标识为多组实例标识，多组实例标识均不包括VNF实例标识，则第一管理单元根据目标NSD所包括的多个VNFD ID中每个VNFD ID分别查找与每个VNFD ID相匹配的VNF实例。In another possible implementation manner, if the foregoing instance identifier does not include the VNF instance identifier, the first management unit may look up the VNF instance that matches the VNFD ID according to the VNFD ID included in the target NSD. Optionally, the first management unit may search for a VNF instance that matches the VNFD ID in the existing VNF instance set, where the existing VNF instance set is a VNF instance set existing in the network architecture. Optionally, the instance identifier may be one or more groups of instance identifiers. Therefore, if the instance identifier is a group instance identifier, and the group instance identifier does not include the VNF instance identifier, the first management unit is configured according to the VNFD included in the target NSD. The ID searches for a VNF instance that matches the VNFD ID; if the instance identifier is a plurality of sets of instance identifiers, and the plurality of sets of instance identifiers do not include the VNF instance identifier, the first management unit is configured according to each of the plurality of VNFD IDs included in the target NSD. The VNFD ID looks for a VNF instance that matches each VNFD ID, respectively.

在一个示例中，第一管理单元根据与VNFD ID相匹配的VNF实例对目标NS进行生命周期管理的过程可以为：In one example, the process by which the first management unit performs lifecycle management on the target NS according to the VNF instance matching the VNFD ID may be:

(1)确定与VNFD ID相匹配的VNF实例的数量是否等于预设阈值，例如，该预设阈值可以为1或2或其它数值；可选的，该预设阈值为1，在该预设阈值为1的情况下，确定与VNFD ID相匹配的VNF实例的数量是否等于预设阈值即确定VNFD ID与相匹配的VNF实例是否为一一对应的关系；(1) determining whether the number of VNF instances matching the VNFD ID is equal to a preset threshold, for example, the preset threshold may be 1 or 2 or other values; optionally, the preset threshold is 1, at the preset If the threshold value is 1, determining whether the number of VNF instances matching the VNFD ID is equal to a preset threshold, that is, determining whether the VNFD ID and the matching VNF instance have a one-to-one correspondence;

(2)若与VNFD ID相匹配的VNF实例的数量等于预设阈值，则第一管理单元根据与VNFD ID相匹配的VNF实例的全部实例对目标NS进行生命周期管理；(2) If the number of VNF instances matching the VNFD ID is equal to a preset threshold, the first management unit performs lifecycle management on the target NS according to all instances of the VNF instance matching the VNFD ID;

(3)若与VNFD ID相匹配的VNF实例的数量小于预设阈值，表明可能不存在与VNFD ID相匹配的VNF实例，则第一管理单元向VNFM单元发送实例化请求，该实例化请求包括VNFD ID，该实例化请求用于请求VNFM单元根据VNFD ID实例化出VNF实例并将VNF实例反馈给第一管理单元，第一管理单元根据VNF实例对目标NS进行生命周期管理；(3) If the number of VNF instances matching the VNFD ID is less than a preset threshold, indicating that there may be no VNF instance matching the VNFD ID, the first management unit sends the VNFM unit to the VNFM unit. And instantiating the request, the instantiation request includes a VNFD ID, the instantiation request is used to request the VNFM unit to instantiate the VNF instance according to the VNFD ID, and feed back the VNF instance to the first management unit, where the first management unit targets the target NS according to the VNF instance. Conduct life cycle management;

(4)若与VNFD ID相匹配的VNF实例的数量大于预设阈值，则第一管理单元向第二管理单元发送选择请求，该选择请求用于指示第二管理单元选择与预设阈值相等数量的VNF实例，该选择请求可以包括VNFD ID以及与VNFD ID相匹配的数量大于预设阈值的VNF实例，第二管理单元的工程师或网络管理员从数量大于预设阈值的VNF实例中选择与预设阈值相等数量的VNF实例，第二管理单元将选择的VNF实例反馈给第一管理单元；或者第一管理单元自主从相匹配的数量大于预设阈值的VNF实例中选择与预设阈值相等数量的VNF实例，第一管理单元可以根据自身或第二管理单元选择的VNF实例对目标NS进行生命周期管理。可选的，第二管理单元或第一管理单元选择的VNF实例为最优的VNF实例。(4) If the number of VNF instances matching the VNFD ID is greater than a preset threshold, the first management unit sends a selection request to the second management unit, where the selection request is used to indicate that the second management unit selects the same amount as the preset threshold. The VNF instance, the selection request may include a VNFD ID and a VNF instance whose number matching the VNFD ID is greater than a preset threshold, and the engineer or network administrator of the second management unit selects and pre-selects from the VNF instance whose number is greater than a preset threshold. Setting a threshold number of VNF instances, the second management unit feeds back the selected VNF instance to the first management unit; or the first management unit autonomously selects the same number of preset VNF instances from the VNF instance that is greater than the preset threshold. The VNF instance, the first management unit may perform lifecycle management on the target NS according to the VNF instance selected by itself or the second management unit. Optionally, the VNF instance selected by the second management unit or the first management unit is an optimal VNF instance.

可以理解的是，第一管理单元根据与VNFD ID相匹配的VNF实例对目标NS进行生命周期管理的过程，可以包括上述“(2)”、“(3)”或“(4)”部分，也可以在此基础上还包括上述“(1)”部分。It can be understood that the process of lifecycle management of the target NS by the first management unit according to the VNF instance matching the VNFD ID may include the foregoing “(2)”, “(3)” or “(4)” part, It is also possible to include the above-mentioned "(1)" portion on the basis of this.

可选的，若上述实例标识为多组实例标识，且有些组实例标识包括VNF实例标识，有些组实例标识不包括VNF实例标识，则对于包括VNF实例标识的实例标识，根据VNF实例标识查找或获取VNF实例标识所对应的VNF实例；对于不包括VNF实例标识的实例标识，根据VNFD ID查找或获取与VNFD ID相匹配的VNF实例，从而对目标NS进行生命周期管理。Optionally, if the instance identifier is a group of instance identifiers, and some group instance identifiers include a VNF instance identifier, and some group instance identifiers do not include the VNF instance identifier, the instance identifiers including the VNF instance identifiers are searched according to the VNF instance identifiers. The VNF instance corresponding to the VNF instance identifier is obtained. For the instance identifier that does not include the VNF instance identifier, the VNF instance matching the VNFD ID is searched or obtained according to the VNFD ID, thereby performing lifecycle management on the target NS.

在一个示例中，若上述生命周期管理请求为更新请求，上述目标NSD还包括新的VNFD ID和新的VNFFG实例标识，则第一管理单元可以根据新的VNFD ID查找与新的VNFD ID相匹配的VNF实例。可选的，第一管理单元可以在已存在的VNF实例集合中查找与新的VNFD ID相匹配的VNF实例。若与新的VNFD ID相匹配的VNF实例的数量大于上述预设阈值，则由第二管理单元或第一管理单元从数量大于预设阈值的VNF实例中选择与预设阈值相等数量的VNF实例。第一管理单元可以根据与新的VNFD ID相匹配的VNF实例和新的VNFFG实例标识对应的VNFFG实例更新目标NS。例如，第一管理单元可以将与新的VNFD ID相匹配的VNF实例和新的VNFFG实例标识对应的VNFFG实例写入目标NS中，以更新目标NS；第一管理单元还可以从目录中获取目标NSD，并将与新的VNFD ID相匹配的VNF实例对应的VNF实例标识和新的VNFFG实例标识写入目标NSD中，以更新目标NSD。第一管理单元在更新目标NS的同时，控制被更新的VNF实例和被更新的VNFFG实例处于终止状态，即不能被其它NS调用。其中，VNFFG实例用于描述VNF实例之间连接关系，因此新的VNFFG实例标识对应的VNFFG实例用于更新与新的VNFD ID相匹配的VNF实例与其它VNF实例之间的连接关系。In an example, if the lifecycle management request is an update request, the target NSD further includes a new VNFD ID and a new VNFFG instance identifier, and the first management unit can match the new VNFD ID according to the new VNFD ID search. The VNF instance. Optionally, the first management unit may look up a VNF instance that matches the new VNFD ID in the existing VNF instance set. If the number of VNF instances matching the new VNFD ID is greater than the preset threshold, the second management unit or the first management unit selects an instance of the VNF that is equal to the preset threshold from the VNF instances whose number is greater than the preset threshold. . The first management unit may update the target NS according to the VNF FF instance corresponding to the new VNFD ID and the new VNFFG instance identifier. For example, the first management unit may identify the VNF instance and the new VNFFG instance identity pair that match the new VNFD ID. The VNFFG instance should be written to the target NS to update the target NS; the first management unit can also obtain the target NSD from the directory, and the VNF instance identifier corresponding to the VNF instance matching the new VNFD ID and the new VNFFG instance. The identifier is written to the target NSD to update the target NSD. The first management unit controls the updated VNF instance and the updated VNFFG instance to be in a terminated state while updating the target NS, that is, cannot be called by other NSs. The VNFFG instance is used to describe the connection relationship between the VNF instances. Therefore, the VNFFG instance of the new VNFFG instance is used to update the connection relationship between the VNF instance matching the new VNFD ID and other VNF instances.

在本发明实施例中，通过第一管理从第二管理单元接收目标NS的生命周期管理请求，该生命周期管理请求包括目标NSD ID；第一管理单元根据目标NSD ID查找目标NSD，该目标NSD包括实例标识，或该目标NSD包括实例标识和VNFD ID，并根据目标NSD包括的实例标识和/或VNFD ID对目标NS进行生命周期管理，从而实现根据NSD所包括的实例标识和/或VNFD ID进行生命周期管理，无需过滤、筛选等过程，精简生命周期管理过程，提高处理效率。In the embodiment of the present invention, the lifecycle management request of the target NS is received from the second management unit by the first management, where the lifecycle management request includes the target NSD ID; the first management unit searches for the target NSD according to the target NSD ID, the target NSD Include an instance identifier, or the target NSD includes an instance identifier and a VNFD ID, and perform lifecycle management on the target NS according to the instance identifier and/or the VNFD ID included in the target NSD, thereby implementing an instance identifier and/or a VNFD ID included according to the NSD.

请参见图3，图3为本发明实施例提供的上载NSD的通信示意图。Referring to FIG. 3, FIG. 3 is a schematic diagram of communication of uploading an NSD according to an embodiment of the present invention.

在301部分，第二管理单元向第一管理单元发送目标NSD的上载请求。In Section 301, the second management unit sends an upload request for the target NSD to the first management unit.

在一个示例中，第二管理单元可以通过第二管理单元与第一管理单元之间的通信接口向第一管理单元发送目标NS的上载请求。现有上载过程中的上载请求包括目标NSD所包括的多个描述符的ID，这些描述符包括VNFD、VNFFGD、VLD、PNFD等。在本发明实施例中，该上载请求除包括上述多个描述符的ID外，还包括目标NSD所包括的实例标识，使得上载至目录的目标NSD的内容更加丰富，便于第二管理单元在根据目标NSD ID查找目标NSD时，能够获取目标NSD所包括的实例标识，从而根据实例标识进行生命周期管理。In one example, the second management unit may send an upload request of the target NS to the first management unit through a communication interface between the second management unit and the first management unit. The upload request in the existing upload process includes IDs of a plurality of descriptors included in the target NSD, and these descriptors include VNFD, VNFFGD, VLD, PNFD, and the like. In the embodiment of the present invention, the upload request includes an instance identifier included in the target NSD in addition to the IDs of the plurality of descriptors, so that the content of the target NSD uploaded to the directory is richer, so that the second management unit is When the target NSD ID finds the target NSD, the instance identifier included in the target NSD can be obtained, thereby performing lifecycle management according to the instance identifier.

可选的，本发明实施例中的上载请求所包括的目标NSD的内容可以由第二管理单元的网络管理员或网络服务的规划设计工程师选定并录入。例如，运营商规划用于服务上海浦东区域视频业务的NSD，则工程师会预先知道已有的上海MME大区的实例和浦东的S-GW/数据网关(Packet Data Network Gateway，P-GW)，那么工程师将两个已有的VNF实例ID(及其它链路接口实例，如VL实例ID，VNFFG实例ID等)作为实例标识输入第二管理单元。 Optionally, the content of the target NSD included in the upload request in the embodiment of the present invention may be selected and input by a network administrator of the second management unit or a planning and design engineer of the network service. For example, if an operator plans to serve an NSD for the Shanghai Pudong regional video service, the engineer will know in advance the existing instance of the Shanghai MME region and the Pudong S-GW/Data Gateway (P-GW). Then, the engineer inputs two existing VNF instance IDs (and other link interface instances, such as VL instance ID, VNFFG instance ID, etc.) as an instance identifier into the second management unit.

对应的，第一管理单元可以从第二管理单元接收上载请求，例如通过第二管理单元与第一管理单元之间的通信接口接收第二管理单元发送的上载请求；并获取该上载请求所包括的内容。Correspondingly, the first management unit may receive an upload request from the second management unit, for example, receiving an upload request sent by the second management unit by using a communication interface between the second management unit and the first management unit; and acquiring the upload request includes Content.

在302部分，第一管理单元上载目标NSD。In section 302, the first management unit uploads the target NSD.

在一个示例中，第一管理单元可以将目标NSD以及目标NSD所包括的内容上载至目录中，该目录可以是图1所示网络结构中的VNF服务目录、VNF目录，也可以是图1所示网络结构中的其它目录，在此不做限定。该目录对目标NSD以及目标NSD所包括的内容进行关联存储，即目标NSD所包括的内容存储在目标NSD名下。In an example, the first management unit may upload the content included in the target NSD and the target NSD to the directory, where the directory may be a VNF service directory, a VNF directory in the network structure shown in FIG. 1, or may be in FIG. Other directories in the network structure are not limited herein. The directory stores the content included in the target NSD and the target NSD, that is, the content included in the target NSD is stored under the target NSD name.

在一个示例中，第一管理单元在上载目标NSD之前，还可以检验上述上载请求是否有效。在一种可能实现的方式中，第一管理单元通过检验该上载请求所包括的实例标识所标识的实例是否存在于网络架构中来检验该上载请求是否有效，例如，该上载请求包括两组实例标识，第一组实例标识包括VNF实例ID 1，VNF实例ID 1所标识的VNF实例1存在于网络架构中；第二组实例标识包括VNF实例ID 2，VNF实例ID 2所标识的VNF实例2存在于网络架构中，那么可确定该上载请求有效。在另一种可能实现的方式中，第一管理单元通过检验该上载请求所包括的实例标识所包括的复用指示信息来检验该上载请求是否有效，即检测实例标识所标识的实例是否允许被至少两个NS调用来检验该上载请求是否有效，具体的通过检验实例标识是否包括可以被至少两个NS复用的字段或实例标识所标识的实例是否包括可以被至少两个NS复用的字段来检验上载请求是否有效，还可通过检验目标NSD所包括的VNFD或VNFD对应的VNF实例是否包括可以被至少两个NS复用的字段来检验上载请求是否有效。若检验出该上载请求有效，则第一管理单元将目标NSD以及目标NSD所包括的内容上载至目录中。In one example, the first management unit may also check whether the upload request is valid before uploading the target NSD. In a possible implementation manner, the first management unit checks whether the upload request is valid by checking whether the instance identified by the instance identifier included in the upload request exists in the network architecture, for example, the upload request includes two sets of instances. The first set of instance identifiers includes the VNF instance ID 1, and the VNF instance ID 1 identified by the VNF instance ID 1 exists in the network architecture; the second set of instance identifiers includes the VNF instance ID 2, and the VNF instance ID 2 identifies the VNF instance 2 Exist in the network architecture, then it can be determined that the upload request is valid. In another possible implementation manner, the first management unit checks whether the upload request is valid by checking the multiplexing indication information included in the instance identifier included in the upload request, that is, detecting whether the instance identified by the instance identifier is allowed to be At least two NS calls to verify whether the upload request is valid, specifically by verifying whether the instance identifier includes a field that can be identified by at least two NS multiplexed fields or instance identifiers, including a field that can be multiplexed by at least two NSs To verify whether the upload request is valid, it is also possible to verify whether the upload request is valid by checking whether the VNF instance corresponding to the VNFD or VNFD included in the target NSD includes a field that can be multiplexed by at least two NSs. If it is checked that the upload request is valid, the first management unit uploads the content included in the target NSD and the target NSD to the directory.

在303部分，第一管理单元向第二管理单元发送确认上载信息。In section 303, the first management unit sends a confirmation upload information to the second management unit.

在一个示例中，第一管理单元在完成上载之后，通过第一管理单元与第二管理单元之间的通信接口向第二管理单元发送确认上载信息，通知第二管理单元目标NSD以及目标NSD所包括的内容已完成上载。这样第二管理单元在向第一管理单元发送生命周期管理请求时，无需发送目标NSD所包括的内容，节省信令开销。 In one example, after the uploading is completed, the first management unit sends a confirmation upload information to the second management unit through the communication interface between the first management unit and the second management unit, and notifies the second management unit of the target NSD and the target NSD. The included content has been uploaded. In this way, the second management unit does not need to send the content included in the target NSD when sending the lifecycle management request to the first management unit, thereby saving signaling overhead.

需要说明的是，图3所示的方法中，上述303部分为可选的部分。It should be noted that in the method shown in FIG. 3, the above-mentioned part 303 is an optional part.

在第一管理单元将目标NSD以及目标NSD所包括的内容上载之后，若第二管理单元接收到工程师或网络管理员输入的针对目标NSD所包括的内容的修改指令，则第二管理单元可以请求第一管理单元对已上载的目标NSD进行修改。After the first management unit uploads the content included in the target NSD and the target NSD, if the second management unit receives the modification instruction input by the engineer or the network administrator for the content included in the target NSD, the second management unit may request The first management unit modifies the uploaded target NSD.

请参见图4，图4为本发明实施例提供的修改NSD的通信示意图。Referring to FIG. 4, FIG. 4 is a schematic diagram of communication for modifying an NSD according to an embodiment of the present invention.

在401部分，第二管理单元向第一管理单元发送目标NSD的修改请求，该修改请求用于请求第一管理单元修改目标NSD。In section 401, the second management unit sends a modification request of the target NSD to the first management unit, the modification request for requesting the first management unit to modify the target NSD.

例如，在第一种情况中，在上载目标NSD时并没有录入某个实例的实例标识，后来又有了该实例，那么工程师或网络管理员需要将该实例标识录入目标NSD中。又例如，在第二种情况中，由于设计调整，工程师或网络管理员需要更改目标NSD中的某个实例标识。基于上述两种情况，在第二管理单元接收到设计师或网络管理员输入的修改指令时，通过第二管理单元与第一管理单元之间的通信接口向第一管理单元发送针对目标NSD的修改请求，该修改请求包括需要增加或更新的实例标识。For example, in the first case, when the target NSD is uploaded and the instance ID of an instance is not entered, and then the instance is created, the engineer or network administrator needs to enter the instance ID into the target NSD. As another example, in the second case, due to design adjustments, the engineer or network administrator needs to change an instance ID in the target NSD. Based on the above two cases, when the second management unit receives the modification instruction input by the designer or the network administrator, the target management node is sent to the first management unit through the communication interface between the second management unit and the first management unit. Modify the request, which includes the instance ID that needs to be added or updated.

对应的，第一管理单元可以从第二管理单元接收目标NSD的修改请求，例如可以通过第一管理单元与第二管理单元之间的通信接口从第二管理单元接收修改请求，并获取该修改请求所包括的增加的或更新的实例标识。Correspondingly, the first management unit may receive the modification request of the target NSD from the second management unit, for example, may receive the modification request from the second management unit by using a communication interface between the first management unit and the second management unit, and obtain the modification.

Specifically, the second management unit may modify the target NSD according to the added or updated instance identifier included in the modification request.

在一个示例中，第一管理单元在修改更新目标NSD之前，还可以检验上述修改请求是否有效。在一种可能实现的方式中，第一管理单元可以通过检验该修改请求所包括的增加的或更新的实例标识所标识的实例是否存在于网络架构中来检验该修改请求是否有效，若存在于网络架构中，则确定该修改请求有效。在另一种可能实现的方式中，第一管理单元可以通过检验该修改请求所包括的增加的或更新的实例标识所包括的复用指示信息来检验该修改请求是否有效，即检测所增加或所更新的实例标识所标识的实例是否允许被至少两个NS调用来检验该修改请求是否有效，具体的通过检验所增加或所更新的实例标识所标识是否包括可以被至少两个NS复用的字段，或所增加或所更新的实例标识所标识的实例是否包括可以被至少两个NS复用的字段来检验修改请求是否有效，若包括该字段，则确定该修改请求有效。若检验出该修改请求有效，则第一管理单元根据该修改请求所包括的增加的或更新的实例标识修改目标NSD。In one example, the first management unit may also check whether the modification request is valid before modifying the update target NSD. In a possible implementation manner, the first management unit may verify whether the modification request is valid by verifying whether the identified instance of the added or updated instance identifier included in the modification request exists in the network architecture, if present, In the network architecture, it is determined that the modification request is valid. In another possible implementation manner, the first management unit may verify whether the modification request is valid by checking the multiplexing indication information included in the added or updated instance identifier included in the modification request, that is, detecting the added or The updated instance identifies whether the identified instance is allowed to be checked by at least two NSs to verify whether the modification request is valid, specifically by verifying the added or updated instance Identifying whether the identifier includes a field that can be multiplexed by at least two NSs, or whether the instance identified by the added or updated instance identifier includes a field that can be multiplexed by at least two NSs to verify whether the modification request is valid, if included This field determines that the modification request is valid. If it is checked that the modification request is valid, the first management unit modifies the target NSD according to the added or updated instance identifier included in the modification request.

在403部分，第一管理单元上载修改后的目标NSD。In section 403, the first management unit uploads the modified target NSD.

在一个示例中，第一管理单元可以上载修改后的目标NSD至目录中。In one example, the first management unit can upload the modified target NSD to the directory.

在404部分，第一管理单元向第二管理单元发送确认修改信息。In section 404, the first management unit sends confirmation modification information to the second management unit.

在一个示例中，第一管理单元可以通过第一管理单元与第二管理单元之间的通信接口向第二管理单元发送确认修改信息，通知第二管理单元目标NSD已完成修改。In an example, the first management unit may send the confirmation modification information to the second management unit through the communication interface between the first management unit and the second management unit to notify the second management unit that the target NSD has completed the modification.

需要说明的是，图4所示的方法中，上述404部分为可选的部分。It should be noted that in the method shown in FIG. 4, the above 404 part is an optional part.
