In the NFV architecture, there can be multiple VNFM122, which is responsible for life cycle management of different types of VNFs.
VIM113，控制和管理VNF140与计算硬件151，存储硬件152，网络硬件153，虚拟计算(virtual computing)154，虚拟存储155，虚拟网络156的交互。例如VIM113执行资源管理功能，包括管理基础设施资源、分配(例如增加资源给虚拟容器)及运行功能(例如收集NFVI故障信息)。VNFM112及VIM113可以相互通信，请求资源分配，交换虚拟化硬件资源配置和状态信息。VIM 113 controls and manages the interaction between VNF 140 and computing hardware 151, storage hardware 152, network hardware 153, virtual computing (virtual computing) 154, virtual storage 155, and virtual network 156. For example, VIM113 performs resource management functions, including managing infrastructure resources, allocation (such as adding resources to virtual containers), and operation functions (such as collecting NFVI fault information). VNFM112 and VIM113 can communicate with each other, request resource allocation, and exchange virtualized hardware resource configuration and status information.
OSS/BSS120主要面向电信服务运营商，支持各种端到端电信业务，可以提供综合的网络管理和业务运营功能。其中，OSS支持的管理功能包括：网络配置，业务提供，故障管理等。BSS处理订单，付费，收入等，支持产品管理，订单管理，收益管理及客户管理。OSS/BSS120 is mainly aimed at telecommunications service operators, supports various end-to-end telecommunications services, and can provide comprehensive network management and business operation functions. Among them, the management functions supported by OSS include: network configuration, service provision, fault management, etc. BSS handles orders, payments, revenue, etc., and supports product management, order management, revenue management and customer management.
EM130用于针对VNF执行传统的故障、配置、用户、性能和安全管理(fault management,configuration management,account management,performance management,security management，FCAPS)功能，以及向VNFM发起新的VNF的实例化等生命周期管理操作。EM130 is used to perform traditional fault management, configuration, user, performance and security management (fault management, configuration management, account management, performance management, security management, FCAPS) functions for VNF, as well as initiate the instantiation of new VNF to VNFM, etc. Cycle management operations.
VNF140对应于传统非虚拟化网络中的物理网络功能(physical network function，PNF)，如虚拟化的分组核心网(evolved packet core，EPC)节点(例如，移动性管理实体(mobility management entity，MME)，服务网关(serving gateway，SGW)，公用数据网网关(public data network gateway，PGW)等)。网络功能的功能性行为和状态与虚拟化与否无关，NFV技术需求希望VNF和PNF拥有相同的功能性行为和外部接口。VNF140可以由一个或多个更低功能级别的VNF组件(VNF component，VNFC)未组成。因此，一个VNF可以部署在多个虚拟机(virtual machine，VM)上，每个VM承载一个VNFC的功能，VNF也可以部署在一个VM上。VNF140 corresponds to the physical network function (PNF) in traditional non-virtualized networks, such as virtualized packet core (EPC) nodes (e.g., mobility management entity (MME)) , service gateway (serving gateway, SGW), public data network gateway (public data network gateway, PGW), etc.). The functional behavior and status of network functions have nothing to do with whether they are virtualized or not. NFV technical requirements hope that VNF and PNF have the same functional behavior and external interfaces. VNF 140 may be composed of one or more lower functional level VNF components (VNF components, VNFC).

The virtual resource layer may include multiple VMs, or may also include virtual storage, virtual networks, etc. (not shown in Figure 1). The hardware resource layer may include computing hardware, storage hardware, network hardware, etc. (not shown in Figure 1). Hardware in the hardware resource layer may include dedicated processors or general-purpose processors used to provide processing and computing functions, such as central processing units (CPU), devices used to provide storage capabilities, such as disks or Network attached storage (NAS), as well as switches, routers and/or other network devices. The virtual resource layer can be provided to the VNF140 in the form of a virtual machine, for example, one or more virtual machines form a VNF140. The virtualization layer forms a virtual network through hardware in the hardware resource layer to implement communication between multiple virtual machines. For example, the virtual network can encapsulate network virtualization through virtual local area network (VLAN), virtual private LAN service (virtual private LAN service, VPLS), virtual extensible local area network (VxLAN) or universal routing. (nerwork virtualization using generic routing encapsulation, NVGRE) and other technologies are implemented. The virtualization layer in NFVI150 is used to abstract the hardware resources of the hardware resource layer, decouple the VNF140 from the physical layer to which the hardware resources belong, and provide virtual resources to the VNF.

NSD mainly describes the topology structure of network services, and the description information (VNFD, VNF descriptor) of each VNF included in NS. The virtualization connection information VLD (virtual link descriptor) is used in the topology information to describe the connection between VNFs. .
(3)VNFD(3)VNFD
VNFD指的是VNF的描述信息，或者也可以称为VNF描述模板，或者VNF部署模板。VNFD可以包括如下信息：一个或多个VDU的描述信息，一个或多个内部和/或外部连接点(connection point，CP)的描述信息，一个或多个虚拟连接(virtual link，VL)的描述信息等。其中，VDU可以视为一个安装了应用软件的虚拟机，在VDU的描述中包含对该虚拟机的所有虚拟资源的需求描述；CP代表虚拟机上的连接信息，如虚拟网卡(virtual network interface card，vNIC)信息，可以采用互联网(internet protocol，IP)地址或媒体接入控制(media access control，MAC)地址来表示；VL是VNF内连接多个VDU的虚拟连接，可以用连接类型，带宽等信息来表示。VNFD refers to the description information of VNF, or it can also be called VNF description template or VNF deployment template.

(4)虚拟网络的网络类型(4) Network type of virtual network
同VIM创建的虚拟网络主要是两种类型，一种是租户网络(tenant network)，另一种是管理员网络(provider network)，图2示出了一种包括租户网络和管理员网络的网络框架示意图。There are two main types of virtual networks created with VIM, one is the tenant network and the other is the administrator network (provider network). Figure 2 shows a network including the tenant network and the administrator network. Frame diagram.
在图2中，服务器节点一般指的是物理服务器，一个物理服务器上可以部署多个虚拟机。一般物理服务器都是连接在数据中心的路由设备上，这部分连接是物理网络(物理电缆)，一个物理服务器和路由设备之间可以有多条物理网络(如图2中实线所示)。In Figure 2, server nodes generally refer to physical servers, and multiple virtual machines can be deployed on one physical server. Generally, physical servers are connected to the routing equipment in the data center. This part of the connection is the physical network (physical cable). There can be multiple physical networks between a physical server and the routing equipment (as shown by the solid line in Figure 2).
管理员网络是权限比较高的虚拟网络，需要具有数据中心管理权限才可以创建，并且管理员网络需要同某一个物理网络绑定，即管理员网络是基于某个物理网络之上创建的虚拟网络(如图2中点划线所示)。管理员网络还有一个特点是具有同外出网关连接的能力，即可以通过管理员网络实现同数据中心外的设备通信。管理员网络由于需要绑定固定的物理网络，所以在资源数量上有限，同时也可以提供基于物理网络的隔离特性，隔离性更好。The administrator network is a virtual network with relatively high authority. It can be created only if it has data center management permissions. The administrator network needs to be bound to a physical network. That is, the administrator network is a virtual network created based on a physical network. (As shown by the dotted line in Figure 2). Another feature of the administrator network is its ability to connect to outbound gateways, that is, it can communicate with devices outside the data center through the administrator network. The administrator network needs to be bound to a fixed physical network, so it has a limited number of resources. At the same time, it can also provide isolation features based on the physical network, with better isolation.
租户网络是针对普通租户创建使用的网络，不需要数据中心管理权限就可以由租户请求创建，也不需要同特定的物理网络绑定，但是租户网络没有外出通信的功能，不能直接接入外出网关。The tenant network is a network created and used by ordinary tenants. It can be created by tenants without data center management permissions, and does not need to be bound to a specific physical network. However, the tenant network does not have the function of outbound communication and cannot be directly connected to the outbound gateway. .

If the value is any non-empty value, it indicates that the first virtual network is the administrator network. If the value of the first network type information is empty, it indicates that the first virtual network is the tenant network.
作为另一种可能的实现方式，可以通过在网络服务的描述信息中携带或不携带网络类型信息来指示第一虚拟网络的网络类型。例如，在网络服务的描述信息中携带有网络类型信息的情况下，表示第一虚拟网络为管理员网络，在网络服务的描述信息中没有携带网络类型信息的情况下，则隐性指示第一虚拟网络为租户网络。As another possible implementation manner, the network type of the first virtual network may be indicated by carrying or not carrying network type information in the description information of the network service.

示例性地，虚拟基础设施管理器接收来自虚拟网络功能管理器的第二网络创建请求消息之后，根据该第二网络创建请求消息中携带的第二物理网络的信息，创建管理员权网络类型的第二虚拟网络。然后将创建完成的第二虚拟网络的信息发送给网络功能虚拟化编排器。Exemplarily, after the virtual infrastructure manager receives the second network creation request message from the virtual network function manager, it creates an administrative rights network type based on the information of the second physical network carried in the second network creation request message.

Correspondingly, the virtual network function manager receives the authorization response message from the network function virtualization orchestrator.
基于上述方案，可以根据实际需要创建不同类型的虚拟网络。并且，在创建管理员网络时还可以提供用于创建管理员网络的信息(例如物理网络的信息以及管理员权限信息)以保障管理员网络可以成功创建。Based on the above solution, different types of virtual networks can be created according to actual needs. In addition, when creating the administrator network, information used to create the administrator network (such as physical network information and administrator permission information) can also be provided to ensure that the administrator network can be successfully created.

Method 400 may be a possible implementation of the process of creating the first virtual network (eg, S301-S303) in method 300. In the method 400, the operation support system/business support system is OSS/BSS, the network function virtualization orchestrator is NFVO, the virtual network function manager is VNFM, and the virtual infrastructure manager is VIM. The first request message is an NS instantiation request message, and the description is given by taking the description information of the network service as NSD as an example.
在方法400中，NFVO在NS实例化流程中，根据NSD中携带的网络类型信息(即“network-type”参数)确定待创建的虚拟网络的网络类型，并请求VIM创建该网络类型对应的虚拟网络。下面结合图4中的各个步骤对方法400作示例性说明。In method 400, during the NS instantiation process, NFVO determines the network type of the virtual network to be created based on the network type information carried in the NSD (i.e., the "network-type" parameter), and requests VIM to create a virtual network corresponding to the network type. network. The method 400 is illustratively described below in conjunction with each step in FIG. 4 .
S401，OSS/BSS向NFVO发送NSD文件。对应地，NFVO接收来自OSS/BSS的该NSD文件。S401, OSS/BSS sends the NSD file to NFVO. Correspondingly, NFVO receives the NSD file from OSS/BSS.
S402，NFVO保存NSD文件。例如，NFVO将NSD保存在数据库中，并且，该NSD与该NSD的标识对应。S402, NFVO saves the NSD file. For example, NFVO stores the NSD in the database, and the NSD corresponds to the identification of the NSD.
S403，NFVO向OSS/BSS发送响应消息，以指示NSD接收成功。S403, NFVO sends a response message to OSS/BSS to indicate that NSD received successfully.
通过S401-S403，NFVO从OSS/BSS获取并保存了NSD。该NSD可以用于实例化对应的网络服务。下面结合图5介绍一种可能的NSD模型。Through S401-S403, NFVO obtains and saves the NSD from OSS/BSS. This NSD can be used to instantiate the corresponding network service. A possible NSD model is introduced below in conjunction with Figure 5.
从图5中可以看出，NS包括3个VNF，即VNF_1、VNF_2、VNF_3。其中，VNF_1通过接口extCp_1与NsVL_1相连，VNF_2通过接口extCp_2与NsVL_1相连，VNF_3通过接口extCp_3以及extCp_4与NsVL_1相连。NSD例如可以包括如下信息(#后面为注释的内容)：

As can be seen from Figure 5, NS includes 3 VNFs, namely VNF_1, VNF_2, and VNF_3. Among them, VNF_1 is connected to NsVL_1 through interface extCp_1, VNF_2 is connected to NsVL_1 through interface extCp_2, and VNF_3 is connected to NsVL_1 through interfaces extCp_3 and extCp_4. NSD may include, for example, the following information (# followed by comments):

下面针对上述NSD里的基本部署信息进行说明。The following describes the basic deployment information in the above NSD.
在针对VNF_1的虚拟链路连接(nsVirtualLinkConnectivity)信息中，“virtualLinkProfileId＝a”表示VNF_1与NsVL_1连接，其中“a”为NsVL_1的profile id。也就是说，可以在VNF的nsVirtualLinkConnectivity中引用该profile id(即a)，来表示这个VNF与NsVL_1连接。“constituentCpdInfo＝{vnf1Profile-1,extCp_1}”表示VNF_1通过extCp_1连接点与NsVL_1连接。VNF_1与NsVL_1之间的连接可以理解为VNF_1所连接的虚拟网络。“affinityOrAntiAffinityGroupId＝{Group_1}”表示VNF_1(通过extCp_1)所连接的虚拟网络属于Group_1。“network-type”为网络 类型信息，该网络类型信息用于指示VNF_1(通过extCp_1)所连接的虚拟网络的网络类型。“network-type:tenant_network”表示VNF_1(通过extCp_1)所连接的虚拟网络为租户网络。也就是说，在该示例中，当网络类型信息(network-type)取值为“tenant_network”时，表示该网络类型信息所对应的虚拟网络的网络类型为租户网络。In the virtual link connection (nsVirtualLinkConnectivity) information for VNF_1, "virtualLinkProfileId=a" indicates that VNF_1 is connected to NsVL_1, where "a" is the profile id of NsVL_1. In other words, the profile id (i.e. a) can be referenced in the VNF's nsVirtualLinkConnectivity to indicate that this VNF is connected to NsVL_1. "constituentCpdInfo={vnf1Profile-1,extCp_1}" indicates that VNF_1 is connected to NsVL_1 through the extCp_1 connection point. The connection between VNF_1 and NsVL_1 can be understood as the virtual network connected to VNF_1. "affinityOrAntiAffinityGroupId={Group_1}" indicates that the virtual network connected to VNF_1 (through extCp_1) belongs to Group_1. "network-type" is network Type information, which is used to indicate the network type of the virtual network connected to VNF_1 (through extCp_1). "network-type:tenant_network" indicates that the virtual network connected to VNF_1 (through extCp_1) is the tenant network. That is to say, in this example, when the value of the network type information (network-type) is "tenant_network", it means that the network type of the virtual network corresponding to the network type information is a tenant network.
可以理解的是，在另一种可能的实现方式中，也可以通过不在“nsVirtualLinkConnectivity”中携带“network-type”参数来隐性指示VNF_1(通过extCp_1)所连接的虚拟网络为租户网络。It can be understood that in another possible implementation, it is also possible to implicitly indicate that the virtual network connected to VNF_1 (through extCp_1) is a tenant network by not carrying the "network-type" parameter in "nsVirtualLinkConnectivity".
在针对VNF_2的虚拟链路连接(nsVirtualLinkConnectivity)信息中，“virtualLinkProfileId＝a”表示VNF_2与NsVL_1连接；“constituentCpdInfo＝{vnf2Profile-1,extCp_2}”表示VNF_2通过extCp_2连接点同NsVL_1相连。VNF_2与NsVL_1之间的连接可以理解为VNF_2所连接的虚拟网络。“affinityOrAntiAffinityGroupId＝{Group-2}”表示VNF_2(通过extCp_2)所连接的虚拟网络属于Group_2。“network-type:provider_network”表示VNF_2(通过extCp_2)所连接的虚拟网络为管理员网络。也就是说，在该示例中，当网络类型信息(network-type)取值为“provider_network”时，表示该网络类型信息所对应的虚拟网络的网络类型为管理员网络。“externalNetwork:www.network-A.com”表示该管理员网络有访问外部网络的需求，且该外部网络的URL为“www.network-A.com”。In the virtual link connection (nsVirtualLinkConnectivity) information for VNF_2, "virtualLinkProfileId=a" indicates that VNF_2 is connected to NsVL_1; "constituentCpdInfo={vnf2Profile-1, extCp_2}" indicates that VNF_2 is connected to NsVL_1 through the extCp_2 connection point. The connection between VNF_2 and NsVL_1 can be understood as the virtual network connected to VNF_2. "affinityOrAntiAffinityGroupId={Group-2}" indicates that the virtual network connected to VNF_2 (through extCp_2) belongs to Group_2. "network-type:provider_network" indicates that the virtual network connected to VNF_2 (through extCp_2) is the administrator network. That is to say, in this example, when the value of the network type information (network-type) is "provider_network", it means that the network type of the virtual network corresponding to the network type information is the administrator network. "externalNetwork:www.network-A.com" indicates that the administrator network needs to access the external network, and the URL of the external network is "www.network-A.com".
可以理解的是，在另一种可能的实现方式中，在VNF_2所连接的虚拟网络为管理员网络的情况下，“nsVirtualLinkConnectivity”中也可以不携带“network-type”参数，而只携带“externalNetwork”参数，来隐性指示VNF_2所连接的虚拟网络为管理员网络。也就是说，也可以通过“externalNetwork”参数来指示VNF_2所连接的虚拟网络的网络类型。It can be understood that in another possible implementation, when the virtual network connected to VNF_2 is the administrator network, "nsVirtualLinkConnectivity" may not carry the "network-type" parameter, but only carry "externalNetwork" " parameter to implicitly indicate that the virtual network connected to VNF_2 is the administrator network. That is to say, the network type of the virtual network connected to VNF_2 can also be indicated through the "externalNetwork" parameter.
在针对VNF_3的虚拟链路连接(nsVirtualLinkConnectivity)信息中，“virtualLinkProfileId＝a”表示VNF_3与NsVL_1连接；“constituentCpdInfo＝{vnf3Profile-1,extCp_3}”表示VNF_3通过extCp_3同NsVL_1相连。VNF_3与NsVL_3之间的连接可以理解为VNF_3所连接的虚拟网络。“affinityOrAntiAffinityGroupId＝{Group_1,Group_3}”表示VNF_3(通过extCp_3)所连接的虚拟网络属于Group_1和Group_3。该连接没有对应的“network-type”参数和“externalNetwork”参数，表示VNF_3(通过extCp_3)所连接的虚拟网络为租户网络。“constituentCpdInfo＝{vnf3Profile-1,extCp_4}”表示VNF_3还通过extCp_4同NsVL_1相连。“affinityOrAntiAffinityGroupId＝{Group_2,Group_3}”表示VNF_3(通过extCp_4)所连接的虚拟网络属于Group_2和Group_3。“network-type:provider_network”表示VNF_3(通过extCp_4)所连接的虚拟网络为管理员网络。“externalNetwork:www.network-A.com”表示该管理员网络有访问外部网络的需求，且该外部网络的URL为“www.network-A.com”。也就是说，VNF_3包含两个VL连接，描述在VNF_3的nsVirtualLinkConnectivity参数内，其中一个连接描述了VNF_3通过extCp_3同NsVL_1相连，该连接即属于Group_1也属于Group_3；另一个连接描述了VNF_3通过extCp_4同NsVL_1相连，该连接既属于Group_2也属于Group_3。In the virtual link connection (nsVirtualLinkConnectivity) information for VNF_3, "virtualLinkProfileId=a" indicates that VNF_3 is connected to NsVL_1; "constituentCpdInfo={vnf3Profile-1, extCp_3}" indicates that VNF_3 is connected to NsVL_1 through extCp_3. The connection between VNF_3 and NsVL_3 can be understood as the virtual network connected to VNF_3. "affinityOrAntiAffinityGroupId={Group_1,Group_3}" indicates that the virtual network connected to VNF_3 (through extCp_3) belongs to Group_1 and Group_3. This connection has no corresponding "network-type" parameter and "externalNetwork" parameter, indicating that the virtual network connected to VNF_3 (through extCp_3) is a tenant network. "constituentCpdInfo={vnf3Profile-1, extCp_4}" indicates that VNF_3 is also connected to NsVL_1 through extCp_4. "affinityOrAntiAffinityGroupId={Group_2,Group_3}" indicates that the virtual network connected to VNF_3 (through extCp_4) belongs to Group_2 and Group_3. "network-type:provider_network" indicates that the virtual network connected to VNF_3 (through extCp_4) is the administrator network. "externalNetwork:www.network-A.com" indicates that the administrator network needs to access the external network, and the URL of the external network is "www.network-A.com". That is to say, VNF_3 contains two VL connections, which are described in the nsVirtualLinkConnectivity parameter of VNF_3. One of the connections describes that VNF_3 is connected to NsVL_1 through extCp_3. This connection belongs to both Group_1 and Group_3; the other connection describes that VNF_3 is connected to NsVL_1 through extCp_4. connected, the connection belongs to both Group_2 and Group_3.
在针对“Group_1”的描述信息中，“affinityOrAntiAffinity:AFFINITY”表示Group_1是一个亲和组；“scope:L2_NETWORK”表示Group_1的组内成员需要连接在同一个2层网络上。也就是说，VNF_1(通过extCp_1)与NsVL_1之间的连接，和VNF_3(通过extCp_3)与NsVL_1之间的连接需要连接在同一个2层网络上，或者说，VNF_1(通过extCp_1)连接的虚拟网络与VNF_3(通过extCp_3)连接的虚拟网络为同一个2层网络。In the description information for "Group_1", "affinityOrAntiAffinity:AFFINITY" indicates that Group_1 is an affinity group; "scope:L2_NETWORK" indicates that group members of Group_1 need to be connected to the same Layer 2 network. In other words, the connection between VNF_1 (through extCp_1) and NsVL_1, and the connection between VNF_3 (through extCp_3) and NsVL_1 need to be connected to the same layer 2 network, or in other words, the virtual network connected by VNF_1 (through extCp_1) The virtual network connected to VNF_3 (via extCp_3) is the same Layer 2 network.
在针对“Group_2”的描述信息中，“affinityOrAntiAffinity:AFFINITY”表示Group_2是一个亲和组；“scope:L2_NETWORK”表示Group_2的组内成员需要连接在同一个2层网络上。也就是说，VNF_2(通过extCp_2)与NsVL_1之间的连接，和VNF_3(通过extCp_4)与NsVL_1之间的连接需要连接在同一个2层网络上，或者说，VNF_2(通过extCp_2)连接的虚拟网络与VNF_3(通过extCp_4)连接的虚拟网络为同一个2层网络。In the description information for "Group_2", "affinityOrAntiAffinity:AFFINITY" indicates that Group_2 is an affinity group; "scope:L2_NETWORK" indicates that group members of Group_2 need to be connected to the same Layer 2 network. In other words, the connection between VNF_2 (through extCp_2) and NsVL_1, and the connection between VNF_3 (through extCp_4) and NsVL_1 need to be connected to the same layer 2 network, or in other words, the virtual network connected by VNF_2 (through extCp_2) The virtual network connected to VNF_3 (via extCp_4) is the same Layer 2 network.
在针对“Group_2”的描述信息中，“affinityOrAntiAffinity:ANTI-AFFINITY”表示Group_3是一个反亲和组，“scope:L2_NETWORK”表示Group_3的组内成员需要连接在同一个2层网络上。也就是说，VNF_3通过(extCp_3)与NsVL_1之间的连接，和VNF_3通过(extCp_4)与NsVL_1之间的连接不能连接在同一个2层网络上(即需要2层隔离)，或者说，VNF_3(通过extCp_3)连接的虚拟网络，和VNF_3(通过extCp_4)连接的虚拟网络不是同一个2层网络。In the description information for "Group_2", "affinityOrAntiAffinity:ANTI-AFFINITY" indicates that Group_3 is an anti-affinity group, and "scope:L2_NETWORK" indicates that group members of Group_3 need to be connected to the same Layer 2 network. In other words, the connection between VNF_3 through (extCp_3) and NsVL_1, and the connection between VNF_3 through (extCp_4) and NsVL_1 cannot be connected to the same layer 2 network (that is, layer 2 isolation is required), or in other words, VNF_3 ( The virtual network connected via extCp_3) and the virtual network connected by VNF_3 (via extCp_4) are not the same Layer 2 network.
可以理解的是，上述示例是以网络类型信息(即“network-type”参数)和外部网络的信息(即 “externalNetwork”参数)包括在网络服务虚拟链路连接信息(即nsVirtualLinkConnectivity)中为例进行说明的，但本申请并不限于此。在NS中的VL只需要创建一个网络的情况下，还可以将网络类型信息(即“network-type”参数)和外部网络的信息(即“externalNetwork”参数)携带在虚拟链路的描述信息(即VLD)中，本申请对此不作限定。可以理解的是，上述示例中的NSD模型对应多个虚拟网络的创建，因此还可以在NSD中VNF通VLD的描述关系中加入网络标识，该标识用于确认VNF连接对应的网络。例如，可以为VNF_1通过extCp_1与NsVL_1之间的连接分配网络标识#1，为VNF_2通过extCp_2与NsVL_1之间的连接分配网络标识#2，为VNF_3通过extCp_3与NsVL_1之间的连接分配网络标识#3，为VNF_3通过extCp_4与NsVL_1之间的连接分配网络标识#4，这样就可以通过不同的网络标识来区分不同的网络以及不同网络的需求，从而更高效得实现网络的部署。It can be understood that the above example is based on network type information (i.e. "network-type" parameter) and external network information (i.e. The "externalNetwork" parameter) is included in the network service virtual link connection information (ie, nsVirtualLinkConnectivity) as an example for explanation, but the application is not limited to this. When the VL in NS only needs to create one network, you can also carry the network type information (i.e. "network-type" parameter) and external network information (i.e. "externalNetwork" parameter) in the description information of the virtual link ( That is, VLD), this application does not limit this. It can be understood that the NSD model in the above example corresponds to the creation of multiple virtual networks. Therefore, a network identifier can also be added to the description relationship between VNF and VLD in NSD. This identifier is used to confirm the network corresponding to the VNF connection. For example, VNF_1 can be assigned network identification #1 through the connection between extCp_1 and NsVL_1, VNF_2 can be assigned network identification #2 through the connection between extCp_2 and NsVL_1, and VNF_3 can be assigned network identification #3 through the connection between extCp_3 and NsVL_1. , assign network identifier #4 to VNF_3 through the connection between extCp_4 and NsVL_1, so that different networks and different network requirements can be distinguished through different network identifiers, thereby achieving more efficient network deployment.
根据上述NSD的定义，最终部署的NS实例如图6所示。其中，虚拟网络#1和虚拟网络#2为不同的2层网络。VNF_1通过extCp_1与虚拟网络#1连接，VNF_3通过extCp_3也与该虚拟网络#1连接；VNF_2通过extCp_2与虚拟网络#2连接，VNF_3通过extCp_4也与该虚拟网络#2连接。根据上述NSD中的部署信息可至，虚拟网络#1为租户网络，虚拟网络#2为管理员网络。路由设备(Router)用于3层(IP网络)的连接，即连接虚拟网络#1和虚拟网络#2。According to the above definition of NSD, the final deployed NS instance is shown in Figure 6. Among them, virtual network #1 and virtual network #2 are different layer 2 networks. VNF_1 is connected to virtual network #1 through extCp_1, VNF_3 is also connected to virtual network #1 through extCp_3; VNF_2 is connected to virtual network #2 through extCp_2, and VNF_3 is also connected to virtual network #2 through extCp_4. According to the deployment information in the above NSD, virtual network #1 is the tenant network and virtual network #2 is the administrator network. The routing device (Router) is used for layer 3 (IP network) connection, that is, connecting virtual network #1 and virtual network #2.
S404，OSS/BSS向NFVO发送NS实例化请求消息，该NS实例化请求消息用于请求实例化NS。对应地，NFVO接收来自OSS/BSS的该NS实例化请求消息。S404. OSS/BSS sends an NS instantiation request message to NFVO. The NS instantiation request message is used to request to instantiate NS. Correspondingly, NFVO receives the NS instantiation request message from OSS/BSS.
示例性地，该NS实例化请求消息包括该NS对应的NSD的标识。For example, the NS instantiation request message includes the identifier of the NSD corresponding to the NS.
S405，NFVO获取NSD文件。S405, NFVO obtains the NSD file.
示例性地，NFVO接收来自OSS/BSS的该NS实例化请求消息之后，根据该NS实例化请求消息中携带的NSD的标识，在数据库中查询与该NSD的标识对应的NSD。For example, after receiving the NS instantiation request message from the OSS/BSS, the NFVO queries the database for the NSD corresponding to the NSD identification according to the NSD identification carried in the NS instantiation request message.
S406，NFVO向VIM发送网络创建请求消息。S406, NFVO sends a network creation request message to VIM.
S407，VIM向NFVO发送网络创建成功响应消息。S407, VIM sends a network creation success response message to NFVO.
示例性地，NFVO根据NSD请求VIM创建虚拟网络，VIM在创建完成后向NFVO发送网络创建成功响应消息，并在该网络创建成功响应消息中携带创建完成的虚拟网络的信息。For example, NFVO requests VIM to create a virtual network based on the NSD. After the creation is completed, VIM sends a network creation success response message to NFVO, and the network creation success response message carries information about the created virtual network.
下面以图5和图6给出的NSD模型为例进行对该网络创建过程作详细说明。The following describes the network creation process in detail, taking the NSD model shown in Figures 5 and 6 as an example.
NFVO根据NSD中的部署信息确定创建虚拟网络#1和虚拟网络#2，其中，虚拟网络#1为租户网络，虚拟网络#2为管理员网络。NFVO determines to create virtual network #1 and virtual network #2 based on the deployment information in the NSD, where virtual network #1 is the tenant network and virtual network #2 is the administrator network.
首先以NFVO请求VIM创建虚拟网络#1为例进行说明：NFVO向VIM发送网络创建请求消息。可选地，该网络创建请求消息可以携带指示信息以指示待创建的网络为租户网络。VIM接收来自NFVO的该网络创建请求消息，在该网络创建请求消息携带了用于指示待创建的网络为租户网络的情况下，或者在该网络创建请求消息没有携带用于指示待创建的网络的网络类型的信息的情况下，VIM根据该网络创建请求消息创建租户网络(即虚拟网络#1)，并向NFVO发送网络创建成功响应消息，该网络创建成功响应消息中携带该租户网络的信息。First, take NFVO requesting VIM to create virtual network #1 as an example to illustrate: NFVO sends a network creation request message to VIM. Optionally, the network creation request message may carry indication information to indicate that the network to be created is a tenant network. VIM receives the network creation request message from NFVO, and the network creation request message carries the information indicating that the network to be created is a tenant network, or the network creation request message does not carry the information indicating that the network to be created is a tenant network. In the case of network type information, VIM creates a tenant network (i.e., virtual network #1) based on the network creation request message, and sends a network creation success response message to NFVO. The network creation success response message carries the information of the tenant network.
然后以NFVO请求VIM创建虚拟网络#2为例进行说明：NFVO在请求VIM创建虚拟网络#2之前，即在S408，NFVO根据“externalNetwork”参数的取值查询连接该外部网络的物理网络的信息。例如，NFVO向VIM发送查询请求消息，该查询请求消息包括该“externalNetwork”参数的取值，即“www.network-A.com”。VIM接收来自NFVO的该查询请求消息之后，根据该“externalNetwork”参数的取值查询连接该外部网络的物理网络的信息，然后VIM向NFVO发送查询响应消息，并在该查询响应消息中携带该物理网络的信息。进一步地，NFVO向VIM发送网络创建请求消息，并在该网络创建请求消息中携带该物理网络的信息。VIM根据该物理网络的信息创建管理员网络(即虚拟网络#2)，然后向NFVO发送网络创建成功响应消息，并在该网络创建成功响应消息中携带该管理员网络的信息。Next, take NFVO requesting VIM to create virtual network #2 as an example to illustrate: before NFVO requests VIM to create virtual network #2, that is, in S408, NFVO queries the information of the physical network connected to the external network based on the value of the "externalNetwork" parameter. For example, NFVO sends a query request message to VIM, and the query request message includes the value of the "externalNetwork" parameter, that is, "www.network-A.com". After VIM receives the query request message from NFVO, it queries the information of the physical network connected to the external network based on the value of the "externalNetwork" parameter. Then VIM sends a query response message to NFVO, and carries the physical network information in the query response message. Network information. Further, NFVO sends a network creation request message to the VIM, and carries the information of the physical network in the network creation request message. VIM creates an administrator network (ie, virtual network #2) based on the information of the physical network, and then sends a network creation success response message to NFVO, and carries the information of the administrator network in the network creation success response message.
可以理解的是，NFVO可以先请求VIM创建虚拟网络#1，再请求VIM创建虚拟网络#2；或者，NFVO也可以先请求VIM创建虚拟网络#2，再请求VIM创建虚拟网络#1，本申请对此不作限定。It can be understood that NFVO can first request VIM to create virtual network #1, and then request VIM to create virtual network #2; or, NFVO can also first request VIM to create virtual network #2, and then request VIM to create virtual network #1. This application There is no limit to this.
S409，NFVO向VNFM发送VNF实例化请求消息。对应地，VNFM接收来自该NFVO的该VNF实例化请求消息。S409: NFVO sends a VNF instantiation request message to VNFM. Correspondingly, the VNFM receives the VNF instantiation request message from the NFVO.
示例性地，NFVO分别针对要实例化的VNF向VNFM请求实例化这些VNF。下面以图5和图6给出的NSD模型为例进行对该VNF实例化过程作示例性说明。 Illustratively, the NFVO requests the VNFM to instantiate the VNFs to be instantiated respectively. The following takes the NSD model shown in Figures 5 and 6 as an example to illustrate the VNF instantiation process.
根据NSD中的部署信息，VNF_1(通过extCp-2)和VNF3(通过extCp-3)与虚拟网络#1连接，VNF_2(通过extCp-2)和VNF3(通过extCp-4)与虚拟网络#2连接，因此在针对VNF_1的VNF实例化请求消息中，包括NFVO在S407从VIM获取到的租户网络(即虚拟网络#1)的信息，以及用于指示VNF_1通过extCp_1与该租户网络连接的信息；在针对VNF_2的实例化请求消息中，包括NFVO在S407从VIM获取到的管理员网络(即虚拟网络#2)的信息，以及用于指示VNF_2通过extCp_2与该管理员网络连接的信息；在针对VNF-3的实例化请求中，包括NFVO在S407从VIM获取到的管理员网络(即虚拟网络#2)的信息，以及用于指示VNF_3通过extCp_4与该管理员网络连接的信息，还包括NFVO在S407从VIM获取到的租户网络(即虚拟网络#1)的信息，以及用于指示VNF_3通过extCp_3与该租户网络连接的信息。According to the deployment information in the NSD, VNF_1 (via extCp-2) and VNF3 (via extCp-3) are connected to virtual network #1, and VNF_2 (via extCp-2) and VNF3 (via extCp-4) are connected to virtual network #2 , therefore, the VNF instantiation request message for VNF_1 includes the information of the tenant network (i.e., virtual network #1) obtained by NFVO from VIM in S407, and the information used to instruct VNF_1 to connect to the tenant network through extCp_1; in The instantiation request message for VNF_2 includes the information of the administrator network (i.e., virtual network #2) obtained by NFVO from VIM in S407, and the information used to instruct VNF_2 to connect to the administrator network through extCp_2; in the case of VNF The instantiation request of -3 includes the information of the administrator network (i.e. virtual network #2) obtained by NFVO from VIM in S407, as well as the information used to instruct VNF_3 to connect to the administrator network through extCp_4, and also includes the information of NFVO in S407 obtains the information of the tenant network (ie, virtual network #1) from VIM, and the information used to instruct VNF_3 to connect to the tenant network through extCp_3.
S410，VNFM向VIM申请虚拟资源，并请求建立虚拟连接。S410: VNFM applies for virtual resources from VIM and requests to establish a virtual connection.
示例性地，VNFM在收到VNF实例化请求之后，向VIM为每个VNF申请创建虚拟资源，例如创建虚拟机资源，并根据在S410获取的信息，申请建立虚拟机和网络之间的虚拟连接。具体过程可参考现有协议，本申请不作限定。Illustratively, after receiving the VNF instantiation request, the VNFM applies to the VIM to create virtual resources for each VNF, such as creating virtual machine resources, and applies to establish a virtual connection between the virtual machine and the network based on the information obtained in S410 . The specific process may refer to the existing agreement and is not limited by this application.
S411，VNFM向NFVO发送VNF实例化成功响应消息。对应地，NFVO接收来自VNFM的该VNF实例化成功响应消息。S411, VNFM sends a VNF instantiation success response message to NFVO. Correspondingly, NFVO receives the VNF instantiation success response message from VNFM.
示例性地，在虚拟资源申请以及虚拟连接建立完成之后，VNFM向NFVO发送VNF实例化成功响应消息，以指示VNF实例化成功。For example, after the virtual resource application and virtual connection establishment are completed, the VNFM sends a VNF instantiation success response message to the NFVO to indicate that the VNF instantiation is successful.
S412，NFVO向OSS/BSS发送NS实例化成功响应消息。对应地，OSS/BSS接收来自NFVO的该NS实例化成功响应消息。S412, NFVO sends an NS instantiation success response message to OSS/BSS. Correspondingly, OSS/BSS receives the NS instantiation success response message from NFVO.
通过上述方案，可以根据实际需要创建不同类型的虚拟网络。并且，在多个VNF之间存在不同网络连接需求的情况下，也可以按需创建多个不同类型的虚拟网络。具体来说，在上述方法400给出的示例中，通过在NSD中定义不同的亲和组和反亲和组来描述了不同VNF之间的网络连接关系，即VNF_1(通过extCp_1)和VNF_3(通过extCp_3)连接虚拟网络#1，VNF_2(通过extCp_2)和VNF_3(通过extCp_4)连接虚拟网络#2，并且进一步通过NSD中的网络类型信息(即“network-type”参数)描述了对不同网络连接的需求，即虚拟网络#1为租户网络(即虚拟网络#1仅用于VNF之间的通信)，虚拟网络#2为管理员网络(即虚拟网络#2除了满足VNF之间的通信，还需要能够同外部网络通信)。Through the above solutions, different types of virtual networks can be created according to actual needs. Moreover, when there are different network connection requirements between multiple VNFs, multiple virtual networks of different types can also be created on demand. Specifically, in the example given by the above method 400, the network connection relationship between different VNFs is described by defining different affinity groups and anti-affinity groups in the NSD, that is, VNF_1 (through extCp_1) and VNF_3 ( Connect virtual network #1 via extCp_3), VNF_2 (via extCp_2) and VNF_3 (via extCp_4) connect to virtual network #2, and further describe the connection to different networks through the network type information in the NSD (i.e., the "network-type" parameter) requirements, that is, virtual network #1 is a tenant network (that is, virtual network #1 is only used for communication between VNFs), and virtual network #2 is an administrator network (that is, virtual network #2 not only meets the communication between VNFs, but also Need to be able to communicate with external networks).
因此通过上述方案，NFVO可以根据NSD确定待创建的不同虚拟网络的网络类型，并进一步向VIM请求创建不同网络类型对应的虚拟网络。也就是说，上述方案可以避免由于NSD中只有一个VL导致实例化出的2层网络的属性一致的情况，例如，当虚拟网络#2有连接外部网络的需求，而虚拟网络#1没有连接外部网络的需求，但由于NSD中仅包括NsVL_1，因此虚拟网络#1和虚拟网络#2可能会被创建为同样属性的网络。如果将虚拟网络#1和虚拟网络#2都创建为了租户网络，那么便无法满足虚拟网络#2与外部网络连接的需求；如果将虚拟网络#1和虚拟网络#2都创建为了管理员网络，由于管理员网路需要同物理网络映射，还需要管理员权限，因此可能会浪费较大的成本。本申请实施例提供的上述方案可以在NSD去区分对不同网络的创建需求，因此可以实现仅将虚拟网络#2按照管理员网络创建，而将虚拟网络#1按照租户网络创建，从而可以节省成本，提高用户体验。Therefore, through the above solution, NFVO can determine the network types of different virtual networks to be created based on the NSD, and further request VIM to create virtual networks corresponding to different network types. In other words, the above solution can avoid the situation where the attributes of the instantiated layer 2 network are consistent due to only one VL in the NSD. For example, when virtual network #2 has the need to connect to the external network, but virtual network #1 does not connect to the external network. Network requirements, but since the NSD only includes NsVL_1, virtual network #1 and virtual network #2 may be created as networks with the same attributes. If both virtual network #1 and virtual network #2 are created as tenant networks, then the need for virtual network #2 to connect to the external network cannot be met; if both virtual network #1 and virtual network #2 are created as administrator networks, Since the administrator network needs to be mapped with the physical network and requires administrator rights, it may waste a lot of money. The above solution provided by the embodiment of this application can distinguish the creation requirements for different networks in NSD, so it can be achieved that only virtual network #2 is created as the administrator network, and virtual network #1 is created as the tenant network, thereby saving costs. , improve user experience.
图7示出了本申请实施例提供的方法700的示例性流程图。方法700可以是方法300中创建第二虚拟网络的方案1(例如S305-S311)的一种可能的实现方式。在方法700中，以运营支撑***/业务支撑***为OSS/BSS、网络功能虚拟化编排器为NFVO、虚拟网络功能管理器为VNFM、虚拟基础设施管理器为VIM为例进行说明；另外，以第二请求消息为VNF实例化请求消息、以虚拟网络功能的描述信息为VNFD、第二虚拟网络为虚拟网络#3为例进行说明。Figure 7 shows an exemplary flowchart of the method 700 provided by the embodiment of the present application. Method 700 may be a possible implementation of Solution 1 (for example, S305-S311) of creating a second virtual network in method 300.

方法400主要描述了NFVO在NS实例化过程中，根据NSD中携带的网络类型信息确定NS中的VNF连接的虚拟网络的网络类型，然后根据该网络类型请求创建对应网络类型的虚拟网络的方案。而在方法700中，VNFM在VNF实例化过程中，根据VNFD中携带的网络类型信息确定VNF中VDU连接的虚拟网络的网络类型，然后根据该网络类型请求创建对应网络类型的虚拟网络的方案。Method 400 mainly describes the solution in which NFVO determines the network type of the virtual network connected to the VNF in the NS based on the network type information carried in the NSD during the NS instantiation process, and then requests to create a virtual network corresponding to the network type based on the network type. In method 700, during the VNF instantiation process, the VNFM determines the network type of the virtual network connected to the VDU in the VNF based on the network type information carried in the VNFD, and then requests a solution to create a virtual network corresponding to the network type based on the network type.
可以理解的是，方法700可以独立实施，也可以和方法400结合实施。例如，方法700中的S705-S709可以在方法400中的S409之后实施。下面结合图7中的各个步骤对方法700作示例性说明。It can be understood that method 700 can be implemented independently or in combination with method 400. For example, S705-S709 in method 700 may be implemented after S409 in method 400. The method 700 is illustratively described below with reference to each step in FIG. 7 .
S701，OSS/BSS向NFVO发送VNFD文件。对应地，NFVO接收来自OSS/BSS的该VNFD文件。 S701, OSS/BSS sends the VNFD file to NFVO. Correspondingly, NFVO receives the VNFD file from OSS/BSS.
S702，NFVO保存VNFD文件。例如，NFVO将VNFD保存在数据库中，并且，该VNFD与该VNFD的标识对应。S702, NFVO saves the VNFD file. For example, NFVO stores the VNFD in the database, and the VNFD corresponds to the identification of the VNFD.
S703，NFVO向OSS/BSS发送响应消息，以指示VNFD接收成功。S703, NFVO sends a response message to OSS/BSS to indicate that VNFD received successfully.
通过S701-S703，NFVO从OSS/BSS获取并保存了VNFD。该VNFD可以用于实例化对应的网络服务。Through S701-S703, NFVO obtains and saves VNFD from OSS/BSS. The VNFD can be used to instantiate the corresponding network service.
下面结合图8介绍一种可能的VNFD模型，假设该VNFD模型对应图5和图6的示例中的VNF_1。从图8中可以看出，VNF1包括2个VDU，即VDU_1、VDU_2。VDU_1和VDU_2分别描述了对虚拟机资源的需求信息，例如包括虚拟机的CPU、内存等信息。Cp_1和Cp_2用来描述VDU上的链接点信息，比如IP地址等，VDU通过CP连接到网络(VL)上，例如在图7中，VDU_1通过接口Cp_1与VL_1连接，VDU_2通过接口Cp_2与VL_1连接。extCp_1是VNF的外部连接点，外界通过该连接点同VNF通信。A possible VNFD model is introduced below in conjunction with Figure 8. It is assumed that the VNFD model corresponds to VNF_1 in the examples of Figures 5 and 6. As can be seen from Figure 8, VNF1 includes 2 VDUs, namely VDU_1 and VDU_2. VDU_1 and VDU_2 respectively describe the demand information for virtual machine resources, such as the CPU, memory and other information of the virtual machine. Cp_1 and Cp_2 are used to describe link point information on VDU, such as IP address, etc. VDU is connected to the network (VL) through CP. For example, in Figure 7, VDU_1 is connected to VL_1 through interface Cp_1, and VDU_2 is connected to VL_1 through interface Cp_2 . extCp_1 is the external connection point of VNF, and the outside world communicates with VNF through this connection point.
在一种可能的示例中，该VNFD中的VLD例如包括以下信息：
In a possible example, the VLD in the VNFD includes the following information:
在上述示例中，“network_pattern”参数和“external_Network”参数用来描述VL_1在部署时的需求，其中，“network_pattern:provider”表示VL_1需要按照管理员网络(provider network)来创建，或者说，VDU_1和VDU_2连接的虚拟网络的网络类型为管理员网络。“external_Network:10.0.0.1”表示该管理员网络有外部通信的需求，且需要通信的外部网络的地址为“10.0.0.1”。VNFM根据上述参数确定创建管理员网络。In the above example, the "network_pattern" parameter and the "external_Network" parameter are used to describe the deployment requirements of VL_1. Among them, "network_pattern:provider" indicates that VL_1 needs to be created according to the administrator network (provider network), or in other words, VDU_1 and The network type of the virtual network connected to VDU_2 is the administrator network. "external_Network:10.0.0.1" indicates that the administrator network has external communication requirements, and the address of the external network that requires communication is "10.0.0.1". VNFM determines to create an administrator network based on the above parameters.
根据上述VNFD的定义，最终部署的VNF示例如图9所示。VDU_1和VDU_2分别通过Cp_1和Cp_2与虚拟网络#3连接，该虚拟网络#3为管理员网络。According to the above definition of VNFD, the final deployed VNF example is shown in Figure 9. VDU_1 and VDU_2 are connected to virtual network #3 through Cp_1 and Cp_2 respectively. The virtual network #3 is the administrator network.
S704，NFVO向VNFM发送VNF实例化请求消息，该VNF实例化请求消息用于请求实例化VNF。对应的，VNFM接收来自NFVO的该VNF实例化请求消息。S704: NFVO sends a VNF instantiation request message to the VNFM. The VNF instantiation request message is used to request to instantiate the VNF. Correspondingly, VNFM receives the VNF instantiation request message from NFVO.
示例性地，该VNF实例化请求消息包括待实例化的VNF对应的VNFD的标识。Exemplarily, the VNF instantiation request message includes the identification of the VNFD corresponding to the VNF to be instantiated.
进一步地，VNFM获取VNFD，根据该VNFD确定待创建的虚拟网络#3为管理员网络(对应图7中的S705)，然后通过NFVO获取连接外部网络的物理网络的信息，以及用于创建管理员网络的管理员权限信息(对应图7中的S706-S708)，进一步通过该物理网络的信息和该管理员权限信息向VIM请求创建管理员网络(对应图7中的S709)。S705-S709与方法300中的S306、S308-S311类似，为了简洁，这里不再详细说明。Further, the VNFM obtains the VNFD, determines based on the VNFD that the virtual network #3 to be created is the administrator network (corresponding to S705 in Figure 7), and then obtains the information of the physical network connected to the external network through NFVO, and is used to create the administrator network The administrator authority information of the network (corresponding to S706-S708 in Figure 7), and further requests VIM to create an administrator network (corresponding to S709 in Figure 7) through the information of the physical network and the administrator authority information. S705-S709 are similar to S306 and S308-S311 in method 300. For the sake of simplicity, they will not be described in detail here.
S710，VIM向VNFM发送网络创建响应消息，该网络创建响应消息包括已创建的管理员网络的信息。对应地，VNFM接收来自该VIM的网络创建响应消息。S710: VIM sends a network creation response message to VNFM, where the network creation response message includes information about the created administrator network. Correspondingly, the VNFM receives the network creation response message from the VIM.
S711-S712与方法400中的S411-S412类似，这里不再赘述。S711-S712 are similar to S411-S412 in method 400 and will not be described again here.
通过上述方案，可以根据VNFD中的信息确定VDU之间的网络连接需求，然后根据该需求创建对应的网络类型的虚拟网络。Through the above solution, the network connection requirements between VDUs can be determined based on the information in the VNFD, and then a virtual network of the corresponding network type can be created based on the requirements.
图10示出了本申请实施例提供的方法1000的示例性流程图。方法1000可以是方法300中创建第二虚拟网络的方案2(例如S305-S306、S312-S316)的一种可能的实现方式。在方法1000中，以运营支撑***/业务支撑***为OSS/BSS、网络功能虚拟化编排器为NFVO、虚拟网络功能管理器为VNFM、虚拟基础设施管理器为VIM为例进行说明；另外，以第二请求消息为VNF实例化请求消息、以虚拟网络功能的描述信息为VNFD、第二虚拟网络为虚拟网络#3为例进行说明。Figure 10 shows an exemplary flowchart of the method 1000 provided by the embodiment of the present application. Method 1000 may be a possible implementation of solution 2 (for example, S305-S306, S312-S316) of creating a second virtual network in method 300. In the method 1000, the operation support system/business support system is OSS/BSS, the network function virtualization orchestrator is NFVO, the virtual network function manager is VNFM, and the virtual infrastructure manager is VIM as an example; in addition, take The second request message is a VNF instantiation request message, the description information of the virtual network function is VNFD, and the second virtual network is virtual network #3 as an example.
在方法700中，NFVO接收到来自VNFM的授权请求消息后，如果根据该授权请求消息携带的信息确定待创建的虚拟网络为管理员网络的情况下，则NFVO向VNFM提供用于创建该管理员网络的物理网络的信息和管理员权限信息，VNFM根据从NFVO获取到的物理网络的信息和管理员权限信息向VIM请求创建管理员网络。而在方法1000中，NFVO接收到来自VNFM的授权请求消息后，如果根 据该授权请求消息携带的信息确定待创建的虚拟网络为管理员网络的情况下，则NFVO通过VIM获取对应的物理网络的信息后，直接根据该物理网络的信息请求VIM创建管理员网络，然后将创建完成的管理员网络的信息发送给VNFM。In method 700, after NFVO receives the authorization request message from VNFM, if it is determined that the virtual network to be created is an administrator network based on the information carried in the authorization request message, NFVO provides VNFM with the information to create the administrator network. Based on the physical network information and administrator permission information of the network, VNFM requests VIM to create an administrator network based on the physical network information and administrator permission information obtained from NFVO. In method 1000, after NFVO receives the authorization request message from VNFM, if the root If it is determined that the virtual network to be created is the administrator network based on the information carried in the authorization request message, then NFVO obtains the information of the corresponding physical network through VIM and directly requests VIM to create the administrator network based on the information of the physical network, and then Send the created administrator network information to VNFM.
可以理解的是，方法1000可以独立实施，也可以和方法400结合实施。例如，方法1000中的S1005-S1010可以在方法400中的S409之后实施。下面结合图10中的各个步骤对方法1000作示例性说明。It can be understood that method 1000 can be implemented independently or in combination with method 400. For example, S1005-S1010 in method 1000 may be implemented after S409 in method 400. The method 1000 is illustrated below in conjunction with each step in Figure 10.
首先，NFVO从OSS/BSS获取并保存了VNFD(对应图10中的S1001-S1003)，具体过程与方法700中的S701-S703类似，为了简洁，这里不再赘述。First, NFVO obtains and saves the VNFD from OSS/BSS (corresponding to S1001-S1003 in Figure 10). The specific process is similar to S701-S703 in method 700. For the sake of simplicity, it will not be repeated here.
进一步地，NFVO请求VNFM实例化VNF，VNFM获取对应的VNFD，并根据该VNFM确定待创建的虚拟网络#3的网络类型(对应图10中的S1004-S1005)，具体过程与方法700中的S704-S705类似，这里不再赘述。Further, NFVO requests VNFM to instantiate VNF, VNFM obtains the corresponding VNFD, and determines the network type of virtual network #3 to be created based on the VNFM (corresponding to S1004-S1005 in Figure 10), the specific process and method 700 is S704 -S705 is similar, so I won’t go into details here.
在虚拟网络#3为管理员网络的情况下，VNFM在发送给NFVO的授权请求消息中携带该虚拟网络#3对应的外部网络的信息(即VLD中“external network”参数的取值)(对应图10中的S1006)，NFVO根据该外部网络的信息向VIM查询连接该外部网络的物理网络的信息(对应图10中的S1007)，并通过该物理网络的信息向VIM请求创建管理员网络类型的虚拟网络#3(对应图10中的S1008-S1009)，然后NFVO将从VIM获取到的虚拟网络#3的信息通过授权响应消息发送给VNFM(对应图10中的S1010)。S1006-S1010与方法300中的S312-S316类似，这里不再赘述。When virtual network #3 is the administrator network, VNFM carries the information of the external network corresponding to virtual network #3 (that is, the value of the "external network" parameter in the VLD) in the authorization request message sent to NFVO (corresponding to S1006 in Figure 10), NFVO queries VIM for information about the physical network connected to the external network based on the information about the external network (corresponding to S1007 in Figure 10), and requests VIM to create an administrator network type through the information about the physical network. Virtual network #3 (corresponding to S1008-S1009 in Figure 10), and then NFVO sends the information of virtual network #3 obtained from VIM to VNFM through an authorization response message (corresponding to S1010 in Figure 10). S1006-S1010 are similar to S312-S316 in method 300 and will not be described again here.
S1011-S1012与方法400中的S411-S412类似，这里不再赘述。S1011-S1012 are similar to S411-S412 in method 400 and will not be described again here.
通过上述方案，可以根据VNFD中的信息确定VDU之间的网络连接需求，然后根据该需求创建对应的网络类型的虚拟网络。Through the above solution, the network connection requirements between VDUs can be determined based on the information in the VNFD, and then a virtual network of the corresponding network type can be created based on the requirements.
可以理解的是，上述实施例提供的方法是以虚拟机部署的场景为例进行说明的，但本申请提供的方法还可能应用于其他场景中，如容器部署的场景，尤其是针对虚拟机容器的场景。在该场景中，容器安装在虚拟机之上。图11示出了在该场景下的一种可能的VNFD模型。通过图11所示的模型可以发现，该场景下同虚拟机部署的唯一不同是VDU的内部，在该场景下，VDU由容器实现，其他节点(如VduCp_1,internal VL和extCp)与虚拟机部署的场景中的节点类似。It can be understood that the method provided by the above embodiment is explained by taking the virtual machine deployment scenario as an example, but the method provided by this application may also be applied to other scenarios, such as the container deployment scenario, especially for virtual machine containers. scene. In this scenario, the container is installed on top of a virtual machine. Figure 11 shows a possible VNFD model in this scenario. Through the model shown in Figure 11, it can be found that the only difference between the virtual machine deployment in this scenario is the inside of the VDU. In this scenario, the VDU is implemented by the container, and other nodes (such as VduCp_1, internal VL and extCp) are deployed with the virtual machine. The nodes in the scene are similar.
