Description

负载均衡器的连接方法、业务的实例化部署方法及装置Load balancer connection method, business instantiation deployment method and device

技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种负载均衡器的连接方法、业务的实例化部署方法及装置。The present application relates to the field of communications technologies, and in particular, to a method for connecting a load balancer, an exemplary deployment method, and a device.

背景技术Background technique

网络功能虚拟化(英文：Network Function Virtualization，简称：NFV)通过使用通用的硬件设备及虚拟化技术，来承载传统网络中专用设备的功能，从而降低因为部署专用设备带来的昂贵成本。通过软硬件解耦，使网络设备功能不再依赖于专用硬件。其中，能够接收虚拟化请求，并根据请求对相应业务进行虚拟化处理的一方，一般称为虚拟化业务提供方(简称业务提供方)，发起虚拟化请求的一方一般称为业务请求方。Network Function Virtualization (English: Network Function Virtualization, NFV for short) uses the common hardware devices and virtualization technologies to carry the functions of dedicated devices in traditional networks, thereby reducing the expensive cost of deploying dedicated devices. By decoupling hardware and software, network device functions are no longer dependent on dedicated hardware. The party that can receive the virtualization request and perform the virtualization process on the corresponding service according to the request is generally referred to as a virtualization service provider (referred to as a service provider), and the party that initiates the virtualization request is generally referred to as a service requester.

NFV中虚拟化的网络服务(英文：Network Service，简称：NS)可以是一个网络协议多媒体子***(英文：Internet Protocol Multimedia Subsystem，简称：IMS)的网络服务，也可以是一个下一代移动核心网络(英文：Evolved Packet Core，简称：EPC)的网络服务。一个NS中还可能包含若干个虚拟化网络功能模块(英文：Virtualized Network Function，简称：VNF)。在一个VNF中还可以包含多个模块，一个模块可以被称为一个VNFC(VNF component)。The virtualized network service (English: Network Service, NS for short) can be a network service of the Internet Protocol Multimedia Subsystem (IMS) or a next-generation mobile core network. (English: Evolved Packet Core, referred to as: EPC) network services. An NS may also contain several virtualized network function modules (English: Virtualized Network Function, VNF for short). A module can also be included in a VNF, and a module can be called a VNFC (VNF component).

当一个NS在实例化部署时，根据业务的需要，NS内的VNF有可能需要多个实例，同样在VNF内，VNFC也可能需要多个实例。所以在业务进行时，需要利用负载均衡技术对VNF的实例进行选择，从而尽量选择负载较轻的实例为当前的业务服务。When an NS is deployed in an instantiation, the VNF in the NS may need multiple instances according to the needs of the service. Similarly, in the VNF, the VNFC may also need multiple instances. Therefore, when the service is running, it is necessary to use the load balancing technology to select an instance of the VNF, so as to select an instance with a light load as the current service service.

目前NFV中定义了三种负载均衡模型，其中图1a中表示的是外设负载均衡模型。Three load balancing models are currently defined in NFV, and the peripheral load balancing model is shown in Figure 1a.

在图1a的模型中，VNF1与VNF2相互连接。负载均衡器(英文：Load Balancer，简称：LB)是一个单独的VNF，可以为VNF2的实例提供负载均衡的功能。在图1a中，右边的VNF2实例1、VNF2实例2、VNF2实例3是VNF2的3个实例。对于左边的V NF1来说，右边只有一个逻辑的VNF2，当数据从对VNF1发往VNF2时，LB负责选择负载较轻的实例为其服务。在该模型中，LB可以由平台方提供。In the model of Figure 1a, VNF1 and VNF2 are interconnected. Load Balancer (English: Load Balancer, LB for short) is a separate VNF that provides load balancing for instances of VNF2. The function. In Figure 1a, VNF2 instance 1, VNF2 instance 2, VNF2 instance 3 on the right are 3 instances of VNF2. For the left V NF1, there is only one logical VNF2 on the right. When data is sent from VNF1 to VNF2, the LB is responsible for selecting the lighter instance to serve it. In this model, the LB can be provided by the platform side.

再请参考图1b所示，为端到端负载均衡模型。在该模型中，LB设置在对VNF1中。该LB可以为连接的VNF2的多个实例进行负载均衡选择。具体来说，当VNF1需要发送数据到VNF2时，VNF1根据其内置的LB判断VNF2的哪个实例上的负载相对较轻，从而直接将数据发向负载较轻的实例。Referring again to Figure 1b, it is an end-to-end load balancing model. In this model, the LB is set in the pair VNF1. The LB can perform load balancing selection for multiple instances of the connected VNF2. Specifically, when VNF1 needs to send data to VNF2, VNF1 determines which instance of VNF2 is relatively lightly loaded according to its built-in LB, thereby directly transmitting data to the lightly loaded instance.

再请参考图1c所示，为基于基础设施的负载均衡模型。基于基础设施的负载均衡模型在架构上同外设负载均衡相似，最大的区别是外设负载均衡模型(如图1a)中的LB是一个VNF，LB主要通过同被服务的VNF2的交互获取被服务的VNF2上的负载情况，从而实现负载均衡的功能。基于基础设施的负载均衡模型中LB是配置在基础设施层的，比如可以配置在物理服务器上的虚拟机管理器上的虚拟交换机上，或是配置在基础设施层的一个专有的物理设备上。图1c的模型中的LB可以直接同被服务的VNF2上的虚拟机通信，从而获知被服务的VNF2的负载情况。Referring again to Figure 1c, it is an infrastructure-based load balancing model. The infrastructure-based load balancing model is similar in architecture to peripheral load balancing. The biggest difference is that the LB in the peripheral load balancing model (Figure 1a) is a VNF, and the LB is mainly obtained through the interaction with the served VNF2. The load condition on the service VNF2, thus implementing the load balancing function. In an infrastructure-based load balancing model, LB is configured at the infrastructure layer, such as on a virtual switch on a virtual machine manager on a physical server, or on a proprietary physical device at the infrastructure layer. . The LB in the model of Figure 1c can communicate directly with the virtual machine on the served VNF2 to learn the load of the served VNF2.

在现有NFV中虽然定义了以上三种负载均衡模型，却没有定义如何在关于业务的实例化部署过程中如何确定使用的LB类型以及如何将LB连接在业务的VNF的实例之间。Although the above three load balancing models are defined in the existing NFV, there is no definition of how to determine the type of LB used in the process of instantiation deployment of the service and how to connect the LB between instances of the VNF of the service.

The service requesting device can correspond to the network function virtualization service requester. Generally, a service requester is, for example, a carrier network, such as an operational support and billing system.

所述NSD可以采用多种规范进行描述，例如云应用的拓扑和运维规范(英文：Topology and Orchestration Specification for Cloud Applications，简称：TOSCA)。其中第一种描述方法如下：The NSD can be described by using various specifications, such as a topology and an operation specification (English: Topology and Orchestration Specification for Cloud Applications, TOSCA). The first method described is as follows:

tosca_definitions_version:tosca_simple_yaml_1_0_0#定义一个TOSCA的业务模板Tosca_definitions_version:tosca_simple_yaml_1_0_0#Define a TOSCA business template

description:Template with a generic connection between two nodes.#定义该模板的作用为两个节点之间的通用的连接Description:Template with a generic connection between two nodes.#Define the role of this template as a universal connection between two nodes

在本实施例中，描述信息为另一种标记语言(英文：Yet Another Markup Language，简称：YAML)语言版本的TOSCA规范。在本实施例中包含两个节点，分别对应两个VNF。节点1对应连接的第一VNF。节点2对应被连接的第二VNF。根据上述Scalable参数中包含节点2支持的最小实例化个数为3可知节点2在部署时有部署多个实例的需求。所以需要在节点1和节点2之间使用LB。In this embodiment, the description information is another TOSCA specification of a language version of the Yet Another Markup Language (YAML) language. In this embodiment, two nodes are included, which respectively correspond to two VNFs. Node 1 corresponds to the first VNF of the connection. Node 2 corresponds to the second VNF being connected. According to the above Scalable parameter, the minimum number of instantiations supported by the node 2 is 3, and it is known that the node 2 has a requirement to deploy multiple instances at the time of deployment. So you need to use LB between node 1 and node 2.

具体的，在节点1的描述信息中，即第一VNFD中，包含：Capabilities：Loadbalance：E2E。其中，Capabilities是对节点1的能力信息的描述。Loadbalance是本发明新增的一种能力信息，用来表示节点1支持的负载均衡模型。在本实施例中，E2E表明节点1支持端到端的负载均衡模型(如图1b所示的负载均衡模型)。该模型可以用来为被连接的节点2提供端到端的LB。requirements参数中包含了节点1的需求信息，其中connect:Node 2，表明节点1需要同节点2连接，即第一VNF和第二VNF之间的连接信息。Specifically, in the description information of the node 1, that is, the first VNFD, includes: Capabilities: Loadbalance: E2E. Capabilities is a description of the capability information of node 1. Loadbalance is a new capability information of the present invention, which is used to represent the load balancing model supported by node 1. In this embodiment, E2E indicates that node 1 supports an end-to-end load balancing model (as shown in Figure 1b). Balance model). This model can be used to provide an end-to-end LB for connected nodes 2. The requirement parameter contains the requirement information of the node 1, where connect: Node 2, indicating that the node 1 needs to be connected with the node 2, that is, the connection information between the first VNF and the second VNF.

“Loadbalance:external"Loadbalance:external

class：3Class:3

Loadbalance:infrastructureLoadbalance: infrastructure

Loadbalance:E2ELoadbalance: E2E

class：1”代码段表示节点1同节点2之间的连接的进一步需求。在本实施例中，Loadbalance参数是本发明新增的参数，用来表示节点1和节点之间的连接对负载均衡模型的需求。每个loadbalance参数下还有class参数。class参数用来表示对应的负载均衡模型的需求优先级别，比如本实施例中“external”，即外设负载均衡模型(如图1a所示的负载均衡模型)的优先级最高，端到端的负载均衡模型的优先级最低。换言之，所述对LB类型的描述信息包括第一VNFD中包含的第一VNF需求的LB的类型信息或者第二VNFD中包含的第二VNF需求的LB的类型信息，以及每种类型的优先级信息。所述对LB类型的描述信息还包括第一VNFD中包含的第一VNF支持的LB的类型信息。The class: 1" code segment represents a further requirement for the connection between node 1 and node 2. In this embodiment, the Loadbalance parameter is a new parameter of the present invention and is used to indicate that the connection between node 1 and the node is load balanced. The requirements of the model. There is also a class parameter under each loadbalance parameter. The class parameter is used to indicate the priority level of the corresponding load balancing model. For example, in this embodiment, “external” is the peripheral load balancing model (as shown in Figure 1a). The load balancing model has the highest priority, and the end-to-end load balancing model has the lowest priority. In other words, the description information of the LB type includes the type information of the LB of the first VNF requirement included in the first VNFD or the second The type information of the LB of the second VNF requirement included in the VNFD, and the priority information of each type. The description information of the LB type further includes type information of the LB supported by the first VNF included in the first VNFD.

节点2的描述信息中的capabilities参数定义的是节点2的能力信息。在本实施例中，定义了端口的能力信息。该能力信息定义了节点2上对外暴露的连接点的信息，即其他的节点可以通过该端口同该节点相连。在该例中定义了2个连接点，一个是端口号为253的端口，支持的协议为传输控制协议(英文：Transmission Control Protocol，简称：TCP)。参数usage为本发明新增加的参数，用来表示端口253的用途。在本实施例中，端口253可以用来连接负载均衡器。另一个端口采用的协议为超文本传送协议(英文：Hypertext transfer protocol，简称：HTTP)，端口号为254。进一步，端口254可以用来连接业务数据。换言之，第二VNFD中包括第二VNF的端口能力信息，例如端口的端口号、端口的功能信息、端口支持的传输协议等。The capabilities parameter in the description information of the node 2 defines the capability information of the node 2. In this embodiment, the capability information of the port is defined. The capability information defines information about the externally exposed connection point on node 2, that is, other nodes can be connected to the node through the port. In this example, two connection points are defined, one is the port number 253, and the supported protocol is the Transmission Control Protocol (English: Transmission Control Protocol, TCP for short). The parameter usage is a newly added parameter of the invention and is used to indicate the purpose of the port 253. In this embodiment, port 253 can be used to connect to a load balancer. The protocol used by the other port is Hypertext Transfer Protocol (English: Hypertext transfer protocol, HTTP), and the port number is 254. Further, port 254 can be used to connect to the service. data. In other words, the second VNFD includes port capability information of the second VNF, such as a port number of the port, function information of the port, a transmission protocol supported by the port, and the like.

Capabilities参数中还有“scalable”参数。scalable参数定义了实例化部署节点2时所需要的实例的个数，其中“Min_instance”定义的是最小实例化个数，“Max_instance”定义的是最大实例化个数。There is also a "scalable" parameter in the Capabilities parameter. The scalable parameter defines the number of instances needed to instantiate the deployment of node 2, where "Min_instance" defines the minimum number of instantiations, and "Max_instance" defines the maximum number of instantiations.

对所述NSD的第二种描述方法可以是：A second method of describing the NSD can be:

上述第二种描述方法同样为YAML语言版本的TOSCA规范。其中，在对节点1的描述中，与前面的第一种描述方法不同的是，在capabilities参数下不仅增加了Loadbalance参数，在Loadbalance参数下还新增了class参数，用于表示节点1所支持的负载均衡模型的优先级别。例如：在本实施例中，class的值为1，说明对应的E2E模型的优先级最低。换言之，第一VNFD包括第一VNF支持的LB的类型信息以及每种类型的优先级信息。The second description method described above is also the TOSCA specification of the YAML language version. The description of the node 1 is different from the previous description method in that the load balance parameter is added to the capability parameter, and the class parameter is added under the load balance parameter to indicate that the node 1 supports The priority level of the load balancing model. For example, in this embodiment, the value of class is 1, indicating that the corresponding E2E model has the lowest priority. In other words, the first VNFD includes type information of the LB supported by the first VNF and priority information of each type.

在对节点2的描述中，与前面的第一种描述方法不同的是，在requirements参数下新增Loadbalance参数，用来表示节点2对负载均衡模型的需求。该需要是对虚拟业务提供设备提出的需求，即希望虚拟业务提供设备提供怎样的负载均衡器。In the description of node 2, unlike the first method described above, a new Loadbalance parameter is added under the requirements parameter to indicate the requirement of node 2 for the load balancing model. This need is a requirement put forward by the virtual service providing device, that is, what kind of load balancer is desired by the virtual service providing device.

节点2中标示的infrastructure模型的class为“2”，external模型的class为“3”。换言之，第二VNFD包括第二VNF需求的LB的类型信息，以及每种类型的优先级信息。The class of the infrastructure model indicated in node 2 is "2", and the class of the external model is "3". In other words, the second VNFD includes type information of the LB of the second VNF demand, and priority information of each type.

在实际运用中，NSD还包括其他信息，例如NSD的标识信息、生产厂商、版本号、弹性策略、生命周期管理、部署喜好等。这些信息为本领域技术人员所熟知的内容，所以在此不再赘述。In practice, NSD also includes other information, such as NSD identification information, manufacturer, version number, resiliency strategy, lifecycle management, deployment preferences, and so on. These information are well known to those skilled in the art and will not be described here.

在一实施例中，在步骤102中，业务提供设备根据实例化请求获取所述业务的NSD。具体来说，实例化请求中携带有该业务的NSD，所以业务提供设备通过分析所述实例化请求即可获得所述NSD。In an embodiment, in step 102, the service providing device acquires the NSD of the service according to the instantiation request. Specifically, the instantiation request carries the NSD of the service, so the service providing device can obtain the NSD by analyzing the instantiation request.

在另一实施例中，在步骤101之前，所述方法还包括：业务提供设备接收业务请求设备发送的关于所述业务的注册(on-boarding)请求，在该请求中携带所述业务的NSD。业务提供设备将所述NSD信息发送至数据库进行保存。在数据保存完成后，数据库向业务提供设备返回保存成功响应。业务提供设备向业务请求设备发送注册成功响应。在该情况下，在步骤101中，实例化请求中会携带NSD的标识信息。步骤102具体包括：业务提供设备根据实例化请求中携带的NSD的标识信息向数据库获取与该标识信息对应的NSD。在数据库根据该标识信息查询到保存的NSD，业务提供设备接收数据库返回的所述NSD。In another embodiment, before step 101, the method further includes: receiving, by the service providing device An on-boarding request for the service sent by the service requesting device, in which the NSD of the service is carried. The service providing device sends the NSD information to a database for storage. After the data is saved, the database returns a save success response to the service provider. The service providing device sends a registration success response to the service requesting device. In this case, in step 101, the instantiation request carries the identification information of the NSD. The step 102 includes: the service providing device acquires the NSD corresponding to the identifier information from the database according to the identifier information of the NSD carried in the instantiation request. The service providing device receives the NSD returned by the database, by querying the saved NSD according to the identification information.

因此，对应在业务请求设备侧提供的一种业务的实例化的部署方法包括：业务请求设备向业务提供设备发送关于业务的实例化请求；其中，所述实例化请求中携带所述业务的NSD的标识信息或者所述NSD。Therefore, the deployment method corresponding to the instantiation of a service provided on the service requesting device side includes: the service requesting device sends an instantiation request for the service to the service providing device; wherein the instantiated request carries the NSD of the service Identification information or the NSD.

接下来执行步骤103，即业务提供设备获取所述业务提供设备支持的LB类型的信息。其中，所述业务提供设备支持的LB类型的信息例如是存储在存储单元中，业务提供设备通过查询即可获得。Next, step 103 is performed, that is, the service providing device acquires information of the LB type supported by the service providing device. The information of the LB type supported by the service providing device is, for example, stored in a storage unit, and the service providing device is obtained by querying.

接下来执行步骤104，即业务提供设备根据对LB类型的描述信息和业务提供设备支持的LB类型的信息确定所使用的LB类型。Next, step 104 is performed, that is, the service providing device determines the used LB type according to the description information of the LB type and the information of the LB type supported by the service providing device.

可选的，当所述对LB类型的描述信息为需求的LB的类型信息，以及每种类型的优先级信息时，步骤103包括：业务提供设备根据所述需求的LB的类型信息和业务提供设备支持的LB类型的信息确定是否有共同的LB类型；若有，业务提供设备根据优先级信息确定共同的LB类型中的优先级最高的LB类型作为所述所使用的LB类型。其中，所述需求的LB的类型信息为第一VNFD中包含的第一VNF需求的LB的类型信息，或第二VNFD中包含的第二VNF需求的LB的类型信息。Optionally, when the description information of the LB type is the type information of the required LB, and the priority information of each type, the step 103 includes: the service providing device provides the type information and service provision of the LB according to the requirement. The information of the LB type supported by the device determines whether there is a common LB type; if yes, the service providing device determines, according to the priority information, the LB type with the highest priority among the common LB types as the used LB type. The type information of the required LB is the type information of the LB of the first VNF requirement included in the first VNFD, or the type information of the LB of the second VNF requirement included in the second VNFD.

继续以前述第一种和第二种描述方式描述的NSD为例进行说明。假设虚拟业务提供设备既支持外设类型，也支持基于基础设施的类型的负载均衡模型。那么业务提供设备确定出的共同的LB类型为外设类型和基于基础设施的类型。在对LB类型的描述信息中，外设类型的LB的优先级最高，那么业务提供设备就确定外设类型为所述所使用的LB类型。The NSD described in the foregoing first and second descriptions will be described as an example. Assume that the virtual service provider supports both the peripheral type and the infrastructure-based type of load balancing module. type. Then the common LB type determined by the service providing device is a peripheral type and an infrastructure based type. In the description information of the LB type, the LB of the peripheral type has the highest priority, and the service providing device determines that the peripheral type is the LB type used.

如前所述，当对LB类型的描述信息还包括支持的LB的类型信息时，可选的，还包括支持的LB的每种类型的优先级。在该情况下，方法还包括：业务提供设备根据所述需求的LB的类型信息和所述业务提供设备支持的LB类型的信息确定没有共同的LB类型；业务提供设备确定支持的LB的类型作为所述所使用的LB类型。其中，所述支持的LB的类型信息为第一VNFD中包括的第一VNF支持的LB的类型信息。As described above, when the description information of the LB type further includes the type information of the supported LB, optionally, each type of priority of the supported LB is also included. In this case, the method further includes: the service providing device determines that there is no common LB type according to the type information of the required LB and the information of the LB type supported by the service providing device; the service providing device determines the type of the supported LB as The type of LB used. The type information of the supported LB is type information of the LB supported by the first VNF included in the first VNFD.

举例来说，假设虚拟业务提供设备既不支持外设类型，也不支持基于基础设施的类型的负载均衡模型，则确定E2E类型为所述所使用的LB类型。换言之，在该业务实例化部署时，虚拟业务提供设备不提供任何负载均衡器，节点1和节点2之间使用E2E类型的负载均衡器，即使用节点1所携带的LB。For example, assuming that the virtual service providing device supports neither the peripheral type nor the infrastructure-based type of load balancing model, it is determined that the E2E type is the used LB type. In other words, when the service is instantiated, the virtual service providing device does not provide any load balancer, and the E2E type load balancer is used between the node 1 and the node 2, that is, the LB carried by the node 1 is used.

当确定了所使用的LB类型，接下来执行步骤105，即业务提供设备获取所述所使用的LB类型的LB的描述信息。根据确定的所使用的LB的类型的不同，步骤104的具体实施方式也不相同，下面将分别举例进行说明。When the LB type used is determined, step 105 is performed, that is, the service providing device acquires description information of the LB of the used LB type. The specific implementation of step 104 is also different according to the determined type of LB used, which will be respectively exemplified below.

当所述所使用的LB类型为外设LB类型时，步骤105包括：业务提供设备向数据库发送查询可用的外设LB类型的LB实例的请求；如果有，数据库会返回可用的LB实例的地址信息，对应的，业务提供设备将接收到的数据库返回的可用的LB实例的地址信息作为所述LB的描述信息。可选的，除了地址信息，LB的描述信息还可以包括其他信息，例如LB的最大处理容量(比如可连接的实例个数)，处理时间等信息。其中，在本申请所有实施例中，可用的LB实例是指在查询的时刻能够使用的LB实例，例如处于空闲状态的LB实例。When the used LB type is a peripheral LB type, step 105 includes: the service providing device sends a request to the database to query the available LB instance of the peripheral LB type; if there is, the database returns the address of the available LB instance. The information, correspondingly, the service providing device uses the address information of the available LB instance returned by the received database as the description information of the LB. Optionally, in addition to the address information, the description information of the LB may further include other information, such as information about a maximum processing capacity of the LB (such as the number of connectable instances), processing time, and the like. In all the embodiments of the present application, the available LB instance refers to an LB instance that can be used at the time of the query, for example, an LB instance in an idle state.

因为可能在实例化所述业务之前，在其他业务实例化的过程中，生成了外设LB类型的LB实例，所以可以先向数据库查询是否有可用的外设LB类型的LB实例。Because it may be generated during the process of instantiating other services before the business is instantiated. Set the LB instance of the LB type, so you can first query the database for the available LB instance of the peripheral LB type.

可选的，当数据库没有可用的LB实例时，数据库就会返回可用的LB实例的虚拟网络功能描述信息VNFD，对应的，该方法还包括：业务提供设备接收数据库返回的可用的LB实例的VNFD；业务提供设备根据所述LB实例的VNFD向虚拟网络功能管理器(英文：Virtualized Network Function Manager，简称：VNFM)发起实例化外设LB的请求；业务提供设备将接收到的VNFM发送的外设LB实例的地址信息作为所述LB的描述信息。其中，实例化外设LB的请求中需要包含所述LB实例的VNFD。Optionally, when the database does not have an available LB instance, the database returns the virtual network function description information VNFD of the available LB instance. Correspondingly, the method further includes: the service providing device receives the VNFD of the available LB instance returned by the database. The service providing device initiates a request for instantiating the peripheral LB according to the VNFD of the LB instance to the virtual network function manager (English: Virtualized Network Function Manager, VNFM for short); the service providing device will receive the peripheral device sent by the VNFM. The address information of the LB instance is used as the description information of the LB. The VNFD of the LB instance needs to be included in the request for instantiating the peripheral LB.

具体来说，如果数据库中没有可用的外设LB的实例，那么就需要重新实例化一个外设LB的实例，然后在实例化完成之后，业务提供设备获取到该外设LB的实例的地址信息作为所述LB的描述信息。Specifically, if there is no instance of the peripheral LB available in the database, then an instance of a peripheral LB needs to be instantiated, and then after the instantiation is completed, the service providing device obtains the address information of the instance of the peripheral LB. As the description information of the LB.

可选的，在一实施例中，业务请求设备可以事先在业务的实例化请求发起之前，将外设类型的LB的VNFD注册到业务提供设备。在业务的实例化过程中，对LB类型的描述信息中还包括所述VNFD的标识信息。因此，考虑到这种情况，在业务提供设备向数据库查询是否有可用的外设LB类型的LB实例之前，该方法还包括：业务提供设备确定所述对LB类型的描述信息中未包含所述外设LB类型的VNFD的标识信息。换言之，就是在没有事先注册VNFD的情况下，才向数据库发送查询可用的外设LB类型的LB实例的请求。Optionally, in an embodiment, the service requesting device may register the VNFD of the LB of the peripheral type to the service providing device before the initiation of the instantiation request of the service. In the instantiation process of the service, the description information of the LB type further includes the identifier information of the VNFD. Therefore, in consideration of the situation, before the service providing device queries the database for an available LB instance of the peripheral LB type, the method further includes: the service providing device determines that the description information of the LB type does not include the Identification information of the peripheral LB type VNFD. In other words, the request to query the available LB instance of the peripheral LB type is sent to the database without registering the VNFD in advance.

可选的，当所述对LB类型的描述信息中包含所述外设LB类型的VNFD的标识信息时，就说明事先已注册过外设LB的VNFD，所以步骤105包括：业务提供设备根据所述标识信息获取与所述标识信息对应的VNFD；业务提供设备根据所述VNFD向VNFM发起实例化外设LB的请求；业务提供设备将接收到的VNFM发送的外设LB实例的地址信息作为所述LB的描述信息。其中，实例化外设LB的请求包括所述VNFD。Optionally, when the description information of the LB type includes the identifier information of the VNFD of the peripheral LB type, it indicates that the VNFD of the peripheral LB has been registered in advance, so step 105 includes: the service providing device according to the The identifier information acquires a VNFD corresponding to the identifier information; the service providing device initiates a request for instantiating the peripheral LB according to the VNFD to the VNFM; the service providing device uses the received address information of the peripheral LB instance sent by the VNFM as the location Describe the description information of LB. Among them, instantiation The request of the peripheral LB includes the VNFD.

当所述所使用的LB类型为基于基础设施的LB类型时，步骤105具体包括：业务提供设备向VIM发起为所述业务分配基于基础设施的LB的请求；业务提供设备将接收到的VIM发送的可用的基于基础设施的LB的地址信息作为所述LB的描述信息。When the LB type used is an infrastructure-based LB type, the step 105 specifically includes: the service providing device initiates, to the VIM, a request for allocating an infrastructure-based LB for the service; and the service providing device sends the received VIM. The address information of the available infrastructure-based LB is used as the description information of the LB.

通常来讲，在业务提供设备与VIM之间具有“虚拟资源管理”接口。该接口由VIM提供。业务提供设备可以使用该接口向VIM发送资源管理的请求，比如资源的分配，资源的查询，资源的更新，资源的迁移，资源的释放等。但是该接口更多的是提供对业务中VNF资源的管理，比如为某个VNF分配资源以及资源的更新和释放等。在业务提供设备向VIM发起为所述业务分配基于基础设施的LB的请求的步骤中，需要VIM分配基于基础设施的负载均衡器，并不是为VNF本身分配负载均衡器资源，所以需要在业务提供设备和VIM之间使用新的接口来传递负载均衡器的分配请求。在本实施例中，可以定义新的接口名称为“基于基础设施负载均衡器管理”接口。该接口用于业务提供设备向VIM申请基于基础设施负载均衡器的操作，比如申请新的负载均衡器，更新负载均衡器，负载均衡器预留，删除负载均衡器等。步骤105中，使用新的接口向VIM申请分配新的负载均衡器。Generally speaking, there is a "virtual resource management" interface between the service providing device and the VIM. This interface is provided by VIM. The service providing device can use the interface to send resource management requests to the VIM, such as resource allocation, resource query, resource update, resource migration, and resource release. However, the interface is more to provide management of VNF resources in the service, such as allocating resources for a VNF and updating and releasing resources. In the step of the service providing device initiating a request for the VIM to allocate an infrastructure-based LB for the service, the VIM needs to allocate an infrastructure-based load balancer, and does not allocate load balancer resources for the VNF itself, so it needs to be provided in the service. A new interface is used between the device and the VIM to pass the load balancer's allocation request. In this embodiment, a new interface name can be defined as an "infrastructure based load balancer management" interface. The interface is used by the service providing device to apply for an infrastructure load balancer based operation to the VIM, such as applying for a new load balancer, updating the load balancer, balancing the load balancer, and deleting the load balancer. In step 105, the new interface is used to allocate a new load balancer to the VIM.

在VIM接收到分配请求之后，就向基础设施层请求分配基于基础设施的LB。基础设施层然后向VIM返回可用的基于基础设施的LB的地址信息。然后VIM向业务提供设备返回所述地址信息。然后业务提供设备将所述地址信息作为所述LB的描述信息。After the VIM receives the allocation request, it requests the infrastructure layer to allocate the infrastructure-based LB. The infrastructure layer then returns the address information of the available infrastructure-based LB to the VIM. The VIM then returns the address information to the service providing device. The service providing device then uses the address information as the description information of the LB.

需要说明的是，当确定的所使用的LB类型为基于基础设施的LB类型时，另一种可能的实施方式为将连接请求和分配请求合一。具体来说，在步骤104之后，不需要执行步骤105，并且在步骤106中，业务提供设备在接收到所述第一VNF和所述第二VNF都实例化成功的响应消息后，将连接信息和端口能力信息发送给VIM。那么VIM在接收到连接信息和端口能力信息之后，先向基础设施层请求分配基于基础设施的LB。基础设施层然后向VIM返回可用的基于基础设施的LB的地址信息。然后VIM根据LB的地址信息、连接信息和端口能力信息将所述LB连接在第一VNF的实例和第二VNF的实例之间。It should be noted that when the determined LB type used is an infrastructure-based LB type, Another possible implementation is to unify the connection request and the allocation request. Specifically, after step 104, step 105 is not required to be performed, and in step 106, after receiving the response message that both the first VNF and the second VNF are successfully instantiated, the service providing device will connect the information. And port capability information is sent to VIM. Then, after receiving the connection information and port capability information, the VIM first requests the infrastructure layer to allocate the infrastructure-based LB. The infrastructure layer then returns the address information of the available infrastructure-based LB to the VIM. The VIM then connects the LB between the instance of the first VNF and the instance of the second VNF based on the address information, connection information, and port capability information of the LB.

当确定的所使用的LB类型为E2E类型时，因为E2E类型的LB为第一VNF的一部分，在第一VNFD中会携带该LB的LB的描述信息，例如为该LB的地址信息。因此步骤105包括：业务提供设备在第一VNFD中获取E2E类型的LB的LB的描述信息。When the determined LB type is the E2E type, because the LB of the E2E type is part of the first VNF, the description information of the LB of the LB, for example, the address information of the LB, is carried in the first VNFD. Therefore, the step 105 includes: the service providing device acquiring, in the first VNFD, description information of the LB of the E2E type LB.

在步骤105中获取到所使用的LB类型的LB的描述信息之后，并且在接收到第一VNF和第二VNF都实例化成功的响应消息后，接下来执行步骤106，即业务提供设备将所述LB的描述信息发送给VIM，以使VIM能够根据所述连接信息、端口能力信息和所述LB的描述信息将所使用的LB类型的LB连接在第一VNF的实例和第二VNF的实例之间。After obtaining the description information of the used LB of the LB type in step 105, and after receiving the response message that both the first VNF and the second VNF are successfully instantiated, step 106 is performed next, that is, the service providing device will The description information of the LB is sent to the VIM, so that the VIM can connect the used LB type LB to the instance of the first VNF and the instance of the second VNF according to the connection information, the port capability information, and the description information of the LB. between.

具体来说，VIM接收业务提供设备发送的连接请求，在该连接请求中包括业务提供设备在步骤106中所发送的信息。VIM根据所述连接信息，可知第一VNF和第二VNF需要连接，所以将第一VNF的实例同LB相连。VIM再根据第二VNF的端口能力信息，根据端口的功能信息将LB上与所述端口的功能信息相对应的接口与第二VNF上对应的功能的端口连接。例如：LB上用于传输负载检测相关的接口同第二VNF上“usage”为“loadbalance”的端口相连。LB 上用于转发第一VNF发送过来的数据接口同第二VNF上“usage”为“data”的端口相连。可选的，在连接完成后，VIM向业务提供设备发送连接完成的响应消息。Specifically, the VIM receives a connection request sent by the service providing device, and includes, in the connection request, information sent by the service providing device in step 106. Based on the connection information, the VIM knows that the first VNF and the second VNF need to be connected, so the instance of the first VNF is connected to the LB. The VIM further connects the interface corresponding to the function information of the port on the LB to the port corresponding to the function on the second VNF according to the port capability information of the second VNF. For example, the interface on the LB for transmitting load detection is connected to the port on the second VNF whose usage is loadbalance. LB The data interface sent by the first VNF is connected to the port whose "usage" is "data" on the second VNF. Optionally, after the connection is completed, the VIM sends a response message to the service providing device to complete the connection.

进一步，业务提供设备在接收到连接完成的响应消息之后，向业务请求设备发送实例化完成响应。对应的，业务请求设备接收所述实例化完成响应。Further, after receiving the response message that the connection is completed, the service providing device sends an instantiation completion response to the service requesting device. Correspondingly, the service requesting device receives the instantiation completion response.

由以上描述可以，通过本申请实施例中的方法，能够在业务的实例化的部署过程中，确定所使用的LB类型，并将所使用的LB类型的LB连接在两个VNF的实例之间。According to the foregoing description, by using the method in the embodiment of the present application, the LB type used can be determined during the deployment process of the instantiation of the service, and the LB of the LB type used is connected between the instances of the two VNFs. .

以下举几个具体的例子说明本申请实施例中的负载均衡器的连接方法的具体实施过程。Several specific examples are given below to illustrate the specific implementation process of the connection method of the load balancer in the embodiment of the present application.

第一例，请参考图4所示，为本实施例中负载均衡器的连接方法的流程图。该方法包括如下内容。For the first example, please refer to FIG. 4, which is a flowchart of a method for connecting a load balancer in this embodiment. The method includes the following.

步骤201：业务请求设备向虚拟业务提供设备发送业务的注册(on boarding)请求。该请求中包含该业务的NSD。Step 201: The service requesting device sends an on boarding request for the service to the virtual service providing device. The request contains the NSD for the service.

接下来执行步骤202：当业务提供设备接收到注册请求之后，将请求中的NSD发送给数据库进行保存。Next, step 202 is performed: after the service providing device receives the registration request, the NSD in the request is sent to the database for saving.

步骤203：数据库保存完成之后，向业务提供设备返回保存成功响应。Step 203: After the database is saved, return a save success response to the service providing device.

步骤204：业务提供设备在接收到数据库发送的保存成功响应之后，向业务请求设备发送注册成功响应。Step 204: After receiving the save success response sent by the database, the service providing device sends a registration success response to the service requesting device.

步骤205：业务请求设备向业务提供设备发起关于该业务的实例化请求。在该请求中携带该业务的NSD对应的标识信息。Step 205: The service requesting device initiates an instantiation request for the service to the service providing device. The request carries the identification information corresponding to the NSD of the service.

步骤206：业务提供设备根据NSD的标识信息向数据库获取NSD。Step 206: The service providing device acquires the NSD from the database according to the identifier information of the NSD.

步骤207：数据库根据NSD的标识信息查询到NSD，并将NSD返回给业务提供设备。 Step 207: The database queries the NSD according to the NSD identification information, and returns the NSD to the service providing device.

步骤208：业务提供设备对NSD进行分析，根据该NSD对节点1和节点2发起实例化请求的流程。具体来说，业务提供设备针对节点1向虚拟网络功能管理器(英文：Virtualised Network Function Manager，简称：VNFM)发送实例化该节点1的请求。在该请求中包含节点1的VNFD标识。VNFM根据VNFD的标识向数据库查询节点1的VNFD。然后数据库在查询到节点1的VNFD之后，将VNFD返回给VNFM。VNFM根据VNFD向业务提供设备申请资源。资源包括节点1需要的中央处理器(英文：Central Processing Unit，简称：CPU)资源、存储资源等。业务提供设备将资源申请请求发送给VIM，要求VIM为节点1分配相应的资源。VIM向网络功能虚拟化基础设施(英文：Network Functions Virtualization Infrastructure，简称：NFVI)层申请需要的资源。NFVI在确认资源分配成功后，返回资源的地址等信息。VIM向业务提供设备确认资源分配成功，并返回资源的地址等信息。业务提供设备向VNFM确认资源分配成功，并返回资源的地址等信息。VNFM根据分配的资源在分配的地址上创建节点1的实例。业务提供设备确定节点1实例化成功。然后重复上述步骤，对节点2进行实例化。对节点1和节点2的实例化过程为本领域技术人员所熟知的内容，所以在此不再赘述。Step 208: The service providing device analyzes the NSD, and initiates a process of instantiating the request according to the NSD to the node 1 and the node 2. Specifically, the service providing device sends a request for instantiating the node 1 to the virtual network function manager (English: Virtualised Network Function Manager, VNFM for the node 1). The VNFD identity of node 1 is included in the request. The VNFM queries the database for the VNFD of the node 1 based on the identity of the VNFD. The database then returns the VNFD to the VNFM after querying the VNFD of Node 1. The VNFM applies for resources to the service provisioning device according to the VNFD. The resources include the central processing unit (English: Central Processing Unit, CPU for short) resources and storage resources required by the node 1. The service providing device sends a resource request request to the VIM, and the VIM is required to allocate the corresponding resource to the node 1. VIM applies for the required resources to the Network Functions Virtualization Infrastructure (NFVI) layer. After confirming the successful allocation of resources, NFVI returns information such as the address of the resource. The VIM provides the device with the service confirmation that the resource allocation is successful, and returns information such as the address of the resource. The service providing device confirms that the resource allocation is successful to the VNFM, and returns information such as the address of the resource. The VNFM creates an instance of Node 1 at the assigned address based on the allocated resources. The service providing device determines that node 1 is instantiated successfully. Then repeat the above steps to instantiate node 2. The instantiation process for Node 1 and Node 2 is well known to those skilled in the art, and therefore will not be described herein.

步骤209：业务提供设备对NSD中包含的负载均衡模型相关的描述信息做判断。在本实施例中，外设负载均衡模型的优先级最高(前述描述实例中class为3，所以优先级最高)，业务提供设备所在的云平台也支持外设负载均衡模型，那么就确定外设类型的LB作为节点1的实例和节点2的实例之间的LB。Step 209: The service providing device determines the description information related to the load balancing model included in the NSD. In this embodiment, the peripheral load balancing model has the highest priority (class 3 in the foregoing description, so the priority is the highest), and the cloud platform where the service providing device is also supports the peripheral load balancing model, then the peripheral is determined. The type of LB acts as the LB between the instance of node 1 and the instance of node 2.

步骤210：业务提供设备向数据库发送查询其所在的云平台是否有可用的外设负载均衡器的实例。Step 210: The service providing device sends an instance of the peripheral load balancer that is available to the database to query whether the cloud platform is located.

步骤211：如果有查询到可用的外设负载均衡器的实例，数据库则向业务提供设备返回该实例的地址等信息。如果没有可用的实例，则返回可用的外设负载均衡器的描述信息，即外设负载均衡器的VNFD。Step 211: If there is an instance of the available peripheral load balancer queried, the database returns information such as the address of the instance to the service providing device. Returns available peripherals if no instances are available The description of the load balancer, which is the VNFD of the peripheral load balancer.

步骤212：如果数据库返回的是外设负载均衡器的VNFD，业务提供设备则使用该VNFD向VNFM发起实例化一个对应的外设LB实例的请求。在该请求中携带该VNFD。Step 212: If the database returns the VNFD of the peripheral load balancer, the service providing device uses the VNFD to initiate a request to the VNFM to instantiate a corresponding peripheral LB instance. The VNFD is carried in the request.

步骤213：业务提供设备接收VNFM返回的外设LB实例的地址信息。Step 213: The service providing device receives the address information of the peripheral LB instance returned by the VNFM.

步骤214：当节点1和节点2都实例化之后，业务提供设备向VIM请求建立VNF之间的连接，即节点1和节点2的连接。还建立节点2的实例和外设负载均衡器实例之间的连接。在该请求中包括外设LB实例的地址信息、连接信息和端口能力信息。在本实施例中，节点1的实例先和负载均衡器的实例相连，负载均衡器在与节点2的多个实例相连。其中，负载均衡器上用于传输负载检测相关的接口同节点2上“usage”为“Loadbalance”的“Endpoint”相连，负载均衡器上用于转发节点1发送过来的数据接口同节点2上“usage”为“data”的“Endpoint”相连。Step 214: After both node 1 and node 2 are instantiated, the service providing device requests the VIM to establish a connection between the VNFs, that is, the connection between node 1 and node 2. A connection between the instance of Node 2 and the Peripheral Load Balancer instance is also established. The address information, connection information, and port capability information of the peripheral LB instance are included in the request. In this embodiment, the instance of node 1 is first connected to an instance of the load balancer, and the load balancer is connected to multiple instances of node 2. The interface for transmitting load detection on the load balancer is connected to the "Endpoint" where the "usage" is "Loadbalance" on the node 2, and the data interface sent by the forwarding node 1 on the load balancer is the same as the node 2 The usage" is connected to the "Endpoint" of "data".

步骤215：当建立完成之后，VIM向业务提供设备发送完成响应。Step 215: After the establishment is completed, the VIM sends a completion response to the service providing device.

步骤216：业务提供设备向业务请求设备发送实例化完成响应。Step 216: The service providing device sends an instantiation completion response to the service requesting device.

第二例，在本实施例中，业务请求设备设置外设负载均衡模型的优先级最高，当虚拟业务提供设备支持外设负载均衡模型时，在部署过程中会为该业务提供外设负载均衡器。在本实施例中还假设该外设类型的负载均衡器是由请求方提供。因此，请求方在发起注册请求之前将外设类型的负载均衡器的VNFD注册到虚拟业务提供设备。并在业务实例化时，携带该负载均衡器的VNFD的标识信息，指明需要使用该负载均衡器。虚拟业务提供设备会根据请求中的VNFD的标识信息，找到对应的LB的VNFD，并使用该对应的LB的VNFD实例化负载均衡器的实例，并使用该实例为请求的业务提供负载均衡功能。具体请参考图5所示，为本实施例中负载均衡器的连接方法的流程图。该方法包括以下内容。 In the second example, in this embodiment, the service requesting device sets the peripheral load balancing model with the highest priority. When the virtual service providing device supports the peripheral load balancing model, the peripheral load balancing is provided for the service during the deployment process. Device. It is also assumed in this embodiment that the peripheral type of load balancer is provided by the requesting party. Therefore, the requesting party registers the VNFD of the peripheral type load balancer to the virtual service providing device before initiating the registration request. And when the service is instantiated, carrying the identification information of the VNFD of the load balancer, indicating that the load balancer needs to be used. The virtual service providing device finds the VNFD of the corresponding LB according to the identification information of the VNFD in the request, and instantiates the instance of the load balancer by using the VNFD of the corresponding LB, and uses the instance to provide a load balancing function for the requested service. For details, please refer to FIG. 5, which is a flowchart of a method for connecting a load balancer in this embodiment. The method includes the following.

步骤301：业务请求设备发起注册LB的请求。该注册请求中携带该LB的VNFD。该LB的构成及组件都由业务请求设备提供。Step 301: The service requesting device initiates a request to register the LB. The registration request carries the VNFD of the LB. The composition and components of the LB are provided by the service requesting device.

该VNFD的一种可能的描述方式为：One possible way to describe this VNFD is:

其中，“LB123”为该节点模板的标识，即VNFD的标识信息。该节点模板是一个负载均衡器类型的节点。The LB123 is the identifier of the node template, that is, the identifier information of the VNFD. The node template is a node of the load balancer type.

步骤302：业务提供设备将收到的VNFD发送至数据库进行保存。Step 302: The service providing device sends the received VNFD to the database for storage.

步骤303：数据库在保存完成之后向业务提供设备发送保存完成响应。Step 303: The database sends a save completion response to the service providing device after the saving is completed.

步骤304：业务提供设备向业务请求设备发送注册完成响应。Step 304: The service providing device sends a registration completion response to the service requesting device.

步骤305:业务请求设备发起网络服务的注册请求。该请求信息中包含的NSD与第一例中基本相同。不同的是在“external”负载均衡器的需求下面又增加了该负载均衡器的VNFD的标识信息。如果采用步骤201中第一种描述方式的话，可以是：Step 305: The service requesting device initiates a registration request of the network service. The NSD included in the request information is basically the same as in the first example. The difference is that under the "external" load balancer requirements The identification information of the VNFD of the load balancer is added. If the first description in step 201 is used, it can be:

如上所述，新增了“ref_Node_ID”参数。该参数携带一个“external”类型的负载均衡器的VNFD的标识信息，即LB123。该标识信息即对应步骤301中需要保存在数据库上的负载均衡器的VNFD。As mentioned above, the "ref_Node_ID" parameter has been added. This parameter carries the identification information of the VNFD of an "external" type load balancer, that is, LB123. The identification information corresponds to the VNFD of the load balancer that needs to be saved in the database in step 301.

接下来的步骤与第一例基本相同，不同的是，业务提供设备需要确定VNFD的标识信息对应的负载均衡器作为该网络服务的负载均衡器。因此，业务提供设备需要根据VNFD的标识信息，即“LB123”向数据库请求该标识信息对应的VNFD。数据库在查询到该VNFD后发送给业务提供设备。然后业务提供设备使用该VNFD向VNFM发起实例化该负载均衡器的流程。接下来的步骤与第一例相同，在此不再赘述。The next step is basically the same as the first example. The difference is that the service providing device needs to determine the load balancer corresponding to the identification information of the VNFD as the load balancer of the network service. Therefore, the service providing device needs to request the VNFD corresponding to the identifier information according to the identification information of the VNFD, that is, “LB123”. The database is sent to the service providing device after querying the VNFD. The service providing device then uses the VNFD to initiate a process of instantiating the load balancer to the VNFM. The next steps are the same as the first example and will not be described here.

第三例，在本实施例中，业务请求设备设置基于基础设施的负载均衡模型的优先级最高。当虚拟业务提供设备支持基于基础设施负载均衡模型时，在部署过程中会为该业务提供基于基础设施的负载均衡器。请参考图6所示，为本实施例中负载均衡连接方法的流程图。该方法包括以下内容。In the third example, in the present embodiment, the service requesting device sets the infrastructure-based load balancing model with the highest priority. When a virtual service provisioning device supports an infrastructure-based load balancing model, an infrastructure-based load balancer is provided for the service during deployment. Please refer to FIG. 6 , which is a flowchart of a load balancing connection method in this embodiment. The method includes the following.

步骤401与步骤201基本相同，不同的是在NSD中，“infrastructure”类型的class设置为“3”，即基于基础设施的负载均衡模型的优先级最高。Step 401 is basically the same as step 201, except that in the NSD, the class of the "infrastructure" type is set to "3", that is, the load balancing model based on the infrastructure has the highest priority.

步骤402-步骤408与步骤201-步骤208基本相同，在此不再赘述。Steps 402 to 408 are substantially the same as steps 201 to 208, and details are not described herein again.

步骤409：因为假设业务提供设备也支持基于基础设施的LB，所以根据NSD中的需求信息确定LB类型为基于基础设施的LB。Step 409: Since it is assumed that the service providing device also supports the infrastructure-based LB, the LB type is determined to be an infrastructure-based LB according to the demand information in the NSD.

步骤410：业务提供设备向VIM发起请求，为当前业务选择基于基础设施的LB类型。Step 410: The service providing device initiates a request to the VIM, and selects an infrastructure based on the current service. The type of LB applied.

步骤411：VIM向基础设施层请求分配负载均衡器。Step 411: The VIM requests the infrastructure layer to allocate a load balancer.

步骤412：基础设施层向VIM返回基于基础设施的负载均衡器的地址等信息。Step 412: The infrastructure layer returns information such as the address of the infrastructure-based load balancer to the VIM.

步骤413：VIM向业务提供设备返回基于基础设施的负载均衡器的地址等信息。Step 413: The VIM returns information such as an address of the infrastructure-based load balancer to the service providing device.

步骤414：业务提供设备向VIM请求VNF实例之间的连接。其中包括业务中相关的VNF同选择的基于基础设施的负载均衡器的连接。在本实施例中，节点1的实例先同负载均衡器相连。负载均衡器再同节点2的多个实例相连。其中负载均衡器上用于传输负载检测相关的接口同节点2上“usage”为“Loadbalance”的“Endpoint”相连。负载均衡器上用于转发节点1发送过来的数据接口同节点2上“usage”为“data”的“Endpoint”相连。Step 414: The service providing device requests the VIM to connect between the VNF instances. This includes the connection of the relevant VNF in the business to the selected infrastructure-based load balancer. In this embodiment, the instance of node 1 is first connected to the load balancer. The load balancer is then connected to multiple instances of node 2. The interface on the load balancer for transmitting load detection is connected to the Endpoint where the usage is "Loadbalance" on node 2. The data interface sent by the forwarding node 1 on the load balancer is connected to the "Endpoint" whose "usage" is "data" on the node 2.

步骤415：VIM完成连接的建立，向业务提供设备返回完成响应。Step 415: The VIM completes the establishment of the connection, and returns a completion response to the service providing device.

步骤416：业务提供设备向业务请求设备返回实例化完成响应。Step 416: The service providing device returns an instantiation completion response to the service requesting device.
