一种虚拟资源的部署方法、装置及系统A method, device and system for deploying virtual resources

技术领域technical field

本发明涉及通信技术领域，尤其涉及一种虚拟资源的部署方法、装置及系统。The present invention relates to the field of communication technologies, and in particular, to a method, device and system for deploying virtual resources.

背景技术Background technique

随着虚拟化技术的飞速发展，在通用的物理设备上，实现网络中专用的网元设备的功能的网络功能虚拟化(英文：network function virtualization，缩写：NFV)系统逐渐受到人们的重视。With the rapid development of virtualization technology, a network function virtualization (English: network function virtualization, abbreviated: NFV) system that realizes the functions of dedicated network element devices in a network on a general-purpose physical device has gradually attracted people's attention.

在NFV系统中，通常由功能虚拟化调度节点(英文：network functionvirtualization orchestrator，缩写：NFVO)，或者虚拟网络功能管理节点(英文：virtualized network function manager，缩写：VNFM)向虚拟机基础设施管理节点(英文：virtualized infrastructure manager，缩写：VIM)发送资源部署请求消息，以请求VIM将待部署的虚拟资源在该VIM所管理的区域上进行部署。例如，在实例化某个虚拟网络功能(英文：virtualized network function，缩写：VNF)时，NFVO或者VNFM会向VIM发送资源部署请求消息，VIM根据该资源部署请求消息在该VIM所管理的主机(英文：host)上部署组成该VNF所需的虚拟机(英文：virtual machine，VM)。In an NFV system, a function virtualization scheduling node (English: network functionvirtualization orchestrator, abbreviation: NFVO), or a virtual network function management node (English: virtualized network function manager, abbreviation: VNFM) is usually sent to the virtual machine infrastructure management node ( English: virtualized infrastructure manager, abbreviation: VIM) sends a resource deployment request message to request the VIM to deploy the virtual resources to be deployed on the area managed by the VIM. For example, when a virtualized network function (English: virtualized network function, abbreviation: VNF) is instantiated, the NFVO or VNFM will send a resource deployment request message to the VIM, and the VIM will use the resource deployment request message on the host managed by the VIM ( English: host) to deploy the virtual machine (English: virtual machine, VM) required to form the VNF.

然而，通过上述虚拟资源部署的方法，当该VNF的虚拟资源包括多个VM，例如包括5个VM，VIM可能会将该5个VM部署在一台主机上，那么当该主机发生故障时，会导致该5个VM均无法运行，因此，通过上述资源部署的方法会导致虚拟资源部署的可靠性较低。However, through the above virtual resource deployment method, when the virtual resource of the VNF includes multiple VMs, such as including 5 VMs, the VIM may deploy the 5 VMs on one host, then when the host fails, As a result, none of the five VMs can run. Therefore, using the above resource deployment method will result in lower reliability of virtual resource deployment.

VNFM负责VNF的生命周期管理，每个VNF都有一个关联的VNFM。一个VNFM可能管理一个VNF，也可能管理多个相同类型甚至不同类型的VNF。The VNFM is responsible for the lifecycle management of VNFs, and each VNF has an associated VNFM. A VNFM may manage one VNF, or it may manage multiple VNFs of the same type or even different types.

NS目录中存储网络服务描述符(英文：network service descriptor，缩写：NSD)，是描述NS的部署和维护行为的模版，包括业务拓扑以及NS的各项特性，其中，业务拓扑包括VNF的各个组成部分及相互间的关系、虚拟链路(英文：virtual links，缩写：VL)，以及VNF转发表(英文：VNF forwarding graph，缩写：VNFFG)等，可以由NFVO进行读取。NFVO通常根据VSD对NS进行虚拟资源的部署和维护的操作。The network service descriptor (English: network service descriptor, abbreviation: NSD) is stored in the NS directory, which is a template describing the deployment and maintenance behavior of the NS, including the business topology and various features of the NS, where the business topology includes various components of the VNF. Parts and mutual relationships, virtual links (English: virtual links, abbreviation: VL), and VNF forwarding graph (English: VNF forwarding graph, abbreviation: VNFFG), etc., can be read by NFVO. NFVO usually deploys and maintains virtual resources to the NS according to the VSD.

VNF目录存储VNF描述符(英文：VNF descriptor，缩写：VNFD)、软件镜像、文件等，其中VNFD是描述VNF部署和维护行为的模版，可由VNFM或者NFVO进行读取。VNFM或者NFVO通常根据VNFD对VNF进行虚拟资源的部署和维护的操作。The VNF directory stores VNF descriptors (English: VNF descriptor, abbreviation: VNFD), software images, files, etc., where VNFD is a template describing VNF deployment and maintenance behavior, which can be read by VNFM or NFVO. The VNFM or NFVO usually deploys and maintains virtual resources for the VNF according to the VNFD.

VIM负责控制和管理VNFI基础设施中的资源，包括：计算资源、存储资源、网络资源等等，通常这些资源是一个运营商的基础设施。The VIM is responsible for controlling and managing the resources in the VNFI infrastructure, including computing resources, storage resources, network resources, and so on. Usually, these resources are the infrastructure of an operator.

为了便于理解本发明实施例中的方法流程，下面对下述关键词作进一步解释：In order to facilitate understanding of the method flow in the embodiment of the present invention, the following keywords are further explained below:

虚拟单元为虚拟资源的部署过程中的基本单元，例如，在实例化VNF时，需要对组成该VNF的多个VM进行部署，该多个VM中的每个VM即为一个虚拟单元；在实例化NS时，需要对组成该NS的多个VNF进行部署，该多个VNF中的每个VNF即为一个虚拟单元。A virtual unit is a basic unit in the deployment process of virtual resources. For example, when a VNF is instantiated, multiple VMs that make up the VNF need to be deployed, and each VM in the multiple VMs is a virtual unit; When an NS is created, multiple VNFs that make up the NS need to be deployed, and each VNF in the multiple VNFs is a virtual unit.

区域为虚拟资源的部署过程中对可靠性进行限制的区域范围。例如，对于VNF来讲，一个区域可以指一个主机(英文：host)，或者一个机柜(英文：shelve)等，对于NS来讲，一个区域可以指一个郊区的范围，一座城市的范围等具体的地理区域。The region is the region range that limits reliability during the deployment of virtual resources. For example, for VNF, an area can refer to a host (English: host), or a cabinet (English: shelf), etc. For NS, an area can refer to the range of a suburb, the range of a city, etc. geographic area.

可靠性参数具体表现为在对虚拟资源进行部署的过程中，在一个区域上允许部署的虚拟单元的最大数量，可以理解的是，在一个区域上允许部署的虚拟单元的数量越小，该虚拟资源组成的NS或者VNF的可靠性越高。The reliability parameter is specifically expressed as the maximum number of virtual units that can be deployed in an area during the process of deploying virtual resources. It can be understood that the smaller the number of virtual units that can be deployed in an area The reliability of the NS or VNF composed of resources is higher.

需要说明的是，上述NFV系统中的任意一个功能节点可能分布在一个实体设备上，也可能分布在多个实体设备上，NFV系统中的多个功能节点可能分别分布在不同的实体设备上，也可能都分布在同一个实体设备上。可以理解的是，NFV系统中的任意一个功能节点都可能是实体设备内的一个逻辑功能模块，也可能是由多个实体设备组成的一个逻辑功能模块。It should be noted that any functional node in the above-mentioned NFV system may be distributed on one physical device, or may be distributed on multiple physical devices, and multiple functional nodes in the NFV system may be distributed on different physical devices respectively. It may also be distributed on the same physical device. It can be understood that any functional node in the NFV system may be a logical function module in an entity device, or may be a logical function module composed of multiple entity devices.

因此，在本发明实施例中，可以由一个实体设备执行本发明实施例提供的方法中的各个步骤，可以由多个实体设备协作执行本发明实施例提供的方法中的各个步骤，对此本发明不做限定。Therefore, in this embodiment of the present invention, each step in the method provided by the embodiment of the present invention may be performed by one entity device, and each step in the method provided by the embodiment of the present invention may be performed by multiple entity devices in cooperation.

Those skilled in the art should understand that, The specific implementation of the logical function module depends on the hardware resources on the physical device where it is located.

需要说明的是，在本发明实施例中，术语“第一”、“第二”、“第三”仅用于描述目的，用于区分不同的描述对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。It should be noted that, in this embodiment of the present invention, the terms "first", "second" and "third" are only used for description purposes and are used to distinguish different description objects, and cannot be understood as indicating or implying that they are relatively important nature or implicitly indicate the number of technical features indicated.

本发明实施例提供一种虚拟资源的部署方法，如图2所示，该方法可以包括：An embodiment of the present invention provides a method for deploying virtual resources. As shown in FIG. 2 , the method may include:

S101、管理节点向VIM发送第一资源部署请求消息，第一资源部署请求消息用于请求VIM部署待部署的虚拟资源，该虚拟资源中包括至少一个虚拟单元，该第一资源部署请求消息中携带与该虚拟资源对应的可靠性参数。S101. The management node sends a first resource deployment request message to the VIM, where the first resource deployment request message is used to request the VIM to deploy a virtual resource to be deployed, the virtual resource includes at least one virtual unit, and the first resource deployment request message carries Reliability parameters corresponding to the virtual resource.

其中，该可靠性参数用于表征在一个区域内允许部署的虚拟单元的最大数量。Among them, the reliability parameter is used to characterize the maximum number of virtual units allowed to be deployed in an area.

需要说明的是，在本发明实施例中，可靠性参数的表达形式可以包括但不限于绝对参数、相对参数、比例，以及等级中的至少一种。It should be noted that, in this embodiment of the present invention, the expression form of the reliability parameter may include, but is not limited to, at least one of an absolute parameter, a relative parameter, a ratio, and a level.

具体的，例如1、2、5等数值可以表示绝对参数，以绝对参数2为例，表征在同一个区域内最多可以部署2个虚拟单元，例如，实例化某个VNF时，一个主机上最多部署2个组成该VNF的VM，实例化某个NS时，一片郊区范围内最多部署2个组成该NS的VNF。Specifically, values such as 1, 2, and 5 can represent absolute parameters. Takingabsolute parameter 2 as an example, it indicates that at most two virtual units can be deployed in the same area. For example, when a VNF is instantiated, the maximum number of Deploy two VMs that make up the VNF. When an NS is instantiated, a maximum of two VNFs that make up the NS can be deployed within a suburb.

10％、20％、30％等数值可以表示相对参数，以相对参数20％为例，表征在一个区域内最多可以部署多个虚拟单元的数量的20％的虚拟单元。例如组成某个VNF的VM的数量为10，当实例化该VNF时，在一个主机上最多部署10*20％＝2个VM。Values such as 10%, 20%, and 30% can represent relative parameters. Taking the relative parameter 20% as an example, it represents virtual units that can deploy at most 20% of the number of multiple virtual units in an area. For example, the number of VMs constituting a certain VNF is 10. When the VNF is instantiated, a maximum of 10*20%=2 VMs are deployed on one host.

1/2、1/3、2/5等数值可以表示比例，以比例1/3为例，表征在一个区域内最多可以部署多个虚拟单元的数量的1/3的虚拟单元。例如组成某个NS的VNF的数量为8，当实例化该NS时，在一个主机上最多部署2个VNF(8*1/3取整数)。Values such as 1/2, 1/3, and 2/5 can represent the ratio. Taking the ratio of 1/3 as an example, it represents a virtual unit that can be deployed at most 1/3 of the number of multiple virtual units in an area. For example, the number of VNFs that make up an NS is 8. When the NS is instantiated, a maximum of 2 VNFs (8*1/3 are integers) can be deployed on a host.

可选的，还可以将可靠性划分为多个等级，例如可以将可靠性划分为最高、高、中、低，以及最低五个等级，其分别对应的可靠性参数为0％、25％、50％、75％，以及100％。Optionally, reliability can also be divided into multiple levels, for example, reliability can be divided into five levels: highest, high, medium, low, and lowest, and the corresponding reliability parameters are 0%, 25%, 50%, 75%, and 100%.

需要说明的是，网络维护人员可以预先根据网络预计划的部署情况，在每个描述符中设置相对应的可靠性参数，描述符可以包括VNFD或者NSD。从而当管理节点需要部署待部署的虚拟资源时，可以从与该虚拟资源对应的描述符中获取该可靠性参数，从而将该可靠性参数携带在第一资源部署请求消息发送至VIM发送。It should be noted that the network maintenance personnel may set the corresponding reliability parameter in each descriptor according to the pre-planned deployment situation of the network in advance, and the descriptor may include VNFD or NSD. Therefore, when the management node needs to deploy the virtual resource to be deployed, the reliability parameter can be obtained from the descriptor corresponding to the virtual resource, so that the reliability parameter is carried in the first resource deployment request message and sent to the VIM for transmission.

具体的，可靠性参数可以设置在VNFD中的任意模块中，例如VNF模块的部署描述模版(英文：virtualised development unit，缩写：VDU)、内部虚拟链接(英文：internalvirtuallink descriptor，缩写：IVLD)或IVL描述符(英文：IVL descriptor，缩写：IVLD)等。Specifically, the reliability parameter can be set in any module in the VNFD, such as the deployment description template of the VNF module (English: virtualised development unit, abbreviation: VDU), internal virtual link (English: internal virtuallink descriptor, abbreviation: IVLD) or IVL Descriptor (English: IVL descriptor, abbreviation: IVLD) and so on.

因此，管理节点具体可以从VNFC、VDU、IVL、IVLD，或者部署定制化中获取预设的可靠性参数。Therefore, the management node can obtain preset reliability parameters from VNFC, VDU, IVL, IVLD, or deployment customization.

可靠性参数也可以设置在NS D中的任意模块中，例如VL或者VNFFG等。Reliability parameters can also be set in any module in NS D, such as VL or VNFFG.

因此，管理节点具体可以从VL或者VNFFG中获取预设的可靠性参数。Therefore, the management node can specifically acquire the preset reliability parameter from the VL or the VNFFG.

需要说明的是，在本发明实施例中，管理节点可以为NFVO，也可以VNFM。当管理节点为NFVO时，描述符可以为VNFD，也可以为NSD，NFVO可以通过获取VNFD中的信息对VNF进行虚拟资源的部署，也可以通过获取NSD中的信息对NS进行虚拟资源的部署和维护。It should be noted that, in this embodiment of the present invention, the management node may be an NFVO or a VNFM. When the management node is NFVO, the descriptor can be either VNFD or NSD. NFVO can deploy virtual resources to VNF by acquiring information in VNFD, or deploy and deploy virtual resources to NS by acquiring information in NSD. maintain.

当管理节点为VNFM时，描述符可以为VNFD，VNFM可以通过获取VNFD中的信息对VNF进行虚拟资源的部署和维护。When the management node is a VNFM, the descriptor can be a VNFD, and the VNFM can deploy and maintain virtual resources for the VNF by acquiring the information in the VNFD.

S102、VIM接收管理节点发送的第一资源部署请求消息。S102. The VIM receives the first resource deployment request message sent by the management node.

S103、VIM根据该可靠性参数，该VIM所管理的至少一个区域的数量，以及该至少一个虚拟单元的数量，确定该第一资源部署请求消息的请求结果，该请求结果包括该第一资源部署请求消息的请求成功或者失败。S103. The VIM determines a request result of the first resource deployment request message according to the reliability parameter, the number of at least one area managed by the VIM, and the number of the at least one virtual unit, where the request result includes the first resource deployment The request for the request message succeeded or failed.

需要说明的是，该第一资源部署请求消息的请求成功包括VIM成功按照该第一资源部署请求消息中携带的可靠性参数进行资源部署。该第一资源部署请求消息的请求失败包括VIM无法按照该可靠性参数进行资源部署。It should be noted that the successful request of the first resource deployment request message includes that the VIM successfully deploys resources according to the reliability parameter carried in the first resource deployment request message. The request failure of the first resource deployment request message includes that the VIM cannot perform resource deployment according to the reliability parameter.

具体的，上述S103具体可以包括：Specifically, the above S103 may specifically include:

VIM根据该至少一个虚拟单元的数量、该至少一个区域的数量，以及该可靠性参数，确定该至少一个区域的数量是否满足该可靠性参数。The VIM determines whether the number of the at least one area satisfies the reliability parameter according to the number of the at least one virtual unit, the number of the at least one area, and the reliability parameter.

其中，若VIM确定该至少一个区域的数量不满足该可靠性参数，VIM则确定该第一资源部署请求消息的请求失败。Wherein, if the VIM determines that the number of the at least one area does not satisfy the reliability parameter, the VIM determines that the request for the first resource deployment request message fails.

若VIM确定该至少一个区域的数量满足该可靠性参数，VIM则确定该第一资源部署请求消息的请求成功。If the VIM determines that the number of the at least one area satisfies the reliability parameter, the VIM determines that the request of the first resource deployment request message is successful.

示例性的，为了更好的说明VIM根据该至少一个虚拟单元的数量、该至少一个区域的数量，以及该可靠性参数，确定该至少一个区域的数量是否满足该可靠性参数，下面以该至少一个虚拟单元为8台VM，该可靠性参数为2为例进行示例性的说明。Exemplarily, in order to better illustrate that the VIM determines whether the number of the at least one area satisfies the reliability parameter according to the number of the at least one virtual unit, the number of the at least one area, and the reliability parameter, the following uses the at least one area. One virtual unit is 8 VMs, and the reliability parameter is 2 as an example for illustrative description.

VIM接收到该第一资源部署请求消息后，根据该第一资源部署请求消息确定需要部署8台VM，且可靠性参数为2，则VIM确定部署该8台VM至少需要8/2＝4台主机。After the VIM receives the first resource deployment request message, it determines according to the first resource deployment request message that 8 VMs need to be deployed, and the reliability parameter is 2, then the VIM determines that at least 8/2=4 VMs are required to deploy the 8 VMs host.

假设，该VIM所管理的至少一个区域为3台主机，由于在将该8台VM部署在3台主机上时，至少有一台主机上需要部署2台以上的VM，因此并不符合可靠性参数2，而按照可靠性参数2，部署8台VM至少需要4台主机，由于3小于4，因此，VIM确定其管理的主机的数量不满足该可靠性参数，进而VIM确定该第一资源部署请求消息的请求失败，即VIM确定按照该可靠性参数，无法在3台上成功部署该8台VM。Assuming that at least one area managed by the VIM is 3 hosts, since when the 8 VMs are deployed on 3 hosts, at least one host needs to deploy more than 2 VMs, so it does not meet thereliability parameters 2. According toreliability parameter 2, deploying 8 VMs requires at least 4 hosts. Since 3 is less than 4, VIM determines that the number of hosts it manages does not meet the reliability parameter, and then VIM determines the first resource deployment request. The request for the message fails, that is, the VIM determines that the 8 VMs cannot be successfully deployed on the 3 machines according to the reliability parameter.

假设，该VIM所管理的至少一个区域为5台主机，由于5大于4，因此，VIM确定其管理的主机的数量满足该可靠性参数，进而VIM确定该第一资源部署请求消息的请求成功，即VIM确定按照该可靠性参数，能够该5台主机上成功部署该8台VM。Assuming that at least one area managed by the VIM is 5 hosts, since 5 is greater than 4, the VIM determines that the number of hosts managed by the VIM satisfies the reliability parameter, and then the VIM determines that the request for the first resource deployment request message is successful, That is, the VIM determines that the 8 VMs can be successfully deployed on the 5 hosts according to the reliability parameter.

S104、VIM根据该请求结果向管理节点发送资源部署应答消息，该资源部署应答消息用于指示所述第一资源部署请求消息的请求成功或者失败。S104. The VIM sends a resource deployment response message to the management node according to the request result, where the resource deployment response message is used to indicate whether the request of the first resource deployment request message succeeds or fails.

S105、管理节点接收VIM发送的资源部署应答消息。S105. The management node receives the resource deployment response message sent by the VIM.

在本发明实施例中，由于管理节点在向VIM请求资源部署的时，将预设的可靠性参数携带在资源部署请求消息中发送至VIM，从而VIM能够根据该可靠性参数进行虚拟资源的部署，限制了在一个区域上VIM允许部署的虚拟单元的最大数量，从而避免了现有技术中VIM可能将所有的虚拟资源部署在一个区域上，进行提高了资源部署的可靠性。In this embodiment of the present invention, when the management node requests the VIM for resource deployment, the management node carries the preset reliability parameter in the resource deployment request message and sends it to the VIM, so that the VIM can deploy virtual resources according to the reliability parameter , which limits the maximum number of virtual units that the VIM allows to deploy in one area, thereby avoiding that the VIM in the prior art may deploy all virtual resources in one area, thereby improving the reliability of resource deployment.

进一步的，一方面，在该第一资源部署请求消息的请求失败情况下，管理节点和VIM可以执行如下两种后续操作。Further, on the one hand, in the case that the request of the first resource deployment request message fails, the management node and the VIM may perform the following two subsequent operations.

(1)、若VIM确定第一资源部署请求消息的请求失败，则上述资源部署应答消息用于指示该第一资源部署请求消息的请求失败，且该资源部署应答消息中携带VIM所管理的至少一个区域的数量，该至少一个区域的数量用于该管理节点更改可靠性参数，以使得更改后的可靠性参数满足该VIM所管理的区域的数量。(1) If the VIM determines that the request for the first resource deployment request message fails, the above-mentioned resource deployment response message is used to indicate that the request for the first resource deployment request message fails, and the resource deployment response message carries at least one resource managed by the VIM. The number of one area, the number of the at least one area is used by the management node to change the reliability parameter, so that the changed reliability parameter satisfies the number of areas managed by the VIM.

具体的，若VIM确定第一资源部署请求消息的请求失败，结合图2，如图3所示，在上述S105之后，该方法还包括：Specifically, if the VIM determines that the request for the first resource deployment request message fails, with reference to FIG. 2, as shown in FIG. 3, after the above S105, the method further includes:

S106、管理节点根据该至少一个区域的数量和该至少一个虚拟单元的数量，更改该可靠性参数，更改后的可靠性参数满足该至少一个区域的数量。S106. The management node changes the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit, and the changed reliability parameter satisfies the number of the at least one area.

示例性的，假设该至少一个虚拟单元包括8台VM，该至少一个区域包括3台主机。当管理节点接收VIM发送的资源部署应答消息后，确定第一资源部署请求消息的请求失败，并确定VIM所管理的主机共3台，进而管理节点可以确定在3台主机上能够成功部署8台VM的部署方案可以包括“008”和“017”，分别表示8台VM均部署在该3台主机中的同1台主机上，和1台VM部署在3台主机中的某1台主机上，另外7台VM部署在3台主机中的另外1台主机上。以此类推，管理节点可以确定的部署方案还包括“026”、“035”、“044”、“116”、“125”、“134”、“224”，以及“233”。Exemplarily, it is assumed that the at least one virtual unit includes 8 VMs, and the at least one area includes 3 hosts. After the management node receives the resource deployment response message sent by the VIM, it determines that the request for the first resource deployment request message fails, and determines that there are 3 hosts managed by the VIM, and the management node can determine that 8 hosts can be successfully deployed on the 3 hosts. The deployment scheme of VM can include "008" and "017", respectively indicating that 8 VMs are deployed on the same host among the 3 hosts, and 1 VM is deployed on a certain host among the 3 hosts. , another 7 VMs are deployed on another 1 of the 3 hosts. By analogy, the deployment scheme that the management node can determine also includes "026", "035", "044", "116", "125", "134", "224", and "233".

由于在一个区域上允许部署的虚拟单元的最大数量越少，可靠性越高，因此，管理节点可以确定在一个区域上部署的虚拟单元最少的部署方案，即“233”为这10个部署方案中可靠性最高的部署方案，该部署方案中在一个区域上部署的虚拟单元的最大数量为3，即该部署方案对应的可靠性参数为3，因此管理节点可以将可靠性参数由原来的2更改为3。更改后的可靠性参数满足该至少一个区域的数量。Since the less the maximum number of virtual units allowed to be deployed in an area, the higher the reliability. Therefore, the management node can determine the deployment scheme with the fewest virtual units deployed in an area, that is, "233" for these 10 deployment schemes The deployment scheme with the highest reliability in the deployment scheme, the maximum number of virtual units deployed in an area in this deployment scheme is 3, that is, the reliability parameter corresponding to the deployment scheme is 3, so the management node can change the reliability parameter from the original 2. Change to 3. The changed reliability parameter satisfies the number of the at least one area.

S107、管理节点向VIM发送第二资源部署请求消息，该第二资源部署请求消息中携带该更改后的可靠性参数。S107. The management node sends a second resource deployment request message to the VIM, where the second resource deployment request message carries the changed reliability parameter.

值得说明的是，在本发明实施例中，当第一资源部署请求消息的请求失败后，管理节点能够根据实际的物理资源，即该VIM所管理的至少一个区域的数量对原本预设的可靠性参数进行更改，且更改为满足该至少一个区域的数量的参数，并将更改后的可靠性参数携带在第二资源部署请求消息中，发送至VIM，以再次请求VIM根据该更改后的可靠性参数对待部署的虚拟资源进行部署。由于更改后的可靠性参数满足该至少一个区域的数量，因此VIM接收到第二资源部署请求消息后，VIM能够按照更改后的可靠性参数，在该至少一个区域上成功部署该虚拟资源。It is worth noting that, in this embodiment of the present invention, after the request of the first resource deployment request message fails, the management node can, according to the actual physical resources, that is, the number of at least one area managed by the VIM, be more reliable than the original preset. change the reliability parameters to meet the parameters of the number of the at least one area, carry the changed reliability parameters in the second resource deployment request message, and send them to the VIM to request the VIM again according to the changed reliability parameters. The virtual resources to be deployed are deployed with the property parameters. Since the changed reliability parameter satisfies the number of the at least one area, after the VIM receives the second resource deployment request message, the VIM can successfully deploy the virtual resource in the at least one area according to the changed reliability parameter.

可以理解的是，在本发明实施例提供的虚拟资源的部署方法中，由于预设的可靠性参数具有可调性，因此能够在VIM所管理的区域的数量不满足预设的可靠性参数时，对该可靠性进行更改，以保证虚拟资源能够成功部署在该区域上，并保证该虚拟资源部署的可靠性，提高了虚拟资源部署的灵活性。It can be understood that, in the method for deploying virtual resources provided in this embodiment of the present invention, since the preset reliability parameter is adjustable, it can be used when the number of areas managed by the VIM does not meet the preset reliability parameter. , the reliability is changed to ensure that the virtual resource can be successfully deployed in the area, and the reliability of the virtual resource deployment is guaranteed, and the flexibility of the virtual resource deployment is improved.

可选的，在实际应用中，存在一种可能的应用场景，即根据实际工程的需要，在进行虚拟资源部署的过程中，必须严格按照预设的可靠性参数进行资源部署，即不允许更改可靠性参数。那么在本发明实施例中，可以在描述符中设置一个开关项，用于指示是否允许管理节点更改该描述符中预设的可靠性参数。Optionally, in practical applications, there is a possible application scenario, that is, according to the needs of actual projects, in the process of virtual resource deployment, resource deployment must be performed strictly according to the preset reliability parameters, that is, changes are not allowed. reliability parameters. Then, in this embodiment of the present invention, a switch item may be set in the descriptor to indicate whether the management node is allowed to change the reliability parameter preset in the descriptor.

具体的，若开关项开启，则表征允许管理节点更改可靠性参数；若开关项关闭，则表征不允许管理节点更改可靠性参数。Specifically, if the switch item is turned on, it indicates that the management node is allowed to change the reliability parameter; if the switch item is turned off, it indicates that the management node is not allowed to change the reliability parameter.

示例性的，开关项可以为一个标志位，若该标志位赋值为1，则表示开关项开启，若该标志位赋值为0，则表示开关项关闭；也可以用字符串off和on来表征该开关项的关闭和开启，对此，本发明实施例不做限制。Exemplarily, the switch item can be a flag bit, if the flag bit is assigned a value of 1, it means that the switch item is turned on, and if the flag bit is assigned a value of 0, it means that the switch item is turned off; it can also be represented by the strings off and on. The turning off and turning on of the switch item are not limited in this embodiment of the present invention.

进一步的，管理节点在根据至少一个区域的数量和至少一个虚拟单元的数量，更改该可靠性参数之前，管理节点可以先查询保存该可靠性参数的描述符中预设的开关项是否开启，若该开关项开启，管理节点即可执行根据该至少一个区域的数量和该至少一个虚拟单元的数量，更改该可靠性参数的步骤。否则，管理节点不对该可靠性参数进行更改，在这种情况下，管理节点可以向网络维护人员提示该第一资源部署请求消息的请求失败，并将该至少一个区域的数量通知给网络维护人员，从而网络维护人员可以获知VIM所管理的区域的数量不足，进而网络维护人员可以增加部署物理资源，以使得该物理资源可以满足部署待部署的虚拟资源的需求，从而使得待部署的虚拟资源能够按照要求的可靠性参数成功进行部署。Further, before the management node changes the reliability parameter according to the number of at least one area and the number of at least one virtual unit, the management node may first query whether the preset switch item in the descriptor for saving the reliability parameter is enabled, if When the switch is turned on, the management node can execute the step of changing the reliability parameter according to the quantity of the at least one area and the quantity of the at least one virtual unit. Otherwise, the management node does not change the reliability parameter. In this case, the management node may prompt the network maintenance personnel that the request for the first resource deployment request message fails, and notify the network maintenance personnel of the number of the at least one area. , so that the network maintenance personnel can know that the number of areas managed by the VIM is insufficient, and then the network maintenance personnel can increase the deployment of physical resources, so that the physical resources can meet the needs of deploying the virtual resources to be deployed, so that the virtual resources to be deployed can be deployed. The deployment succeeds according to the required reliability parameters.

(2)、若该第一资源部署请求消息的请求失败，则该资源部署应答消息用于指示所述第一资源部署请求消息的请求失败。(2) If the request of the first resource deployment request message fails, the resource deployment response message is used to indicate that the request of the first resource deployment request message fails.

进一步的，在上述S104之前，该方法还包括：Further, before the above S104, the method further includes:

S1、该VIM根据该至少一个区域的数量和该至少一个虚拟单元的数量，更改该可靠性参数，更改后的可靠性参数满足该至少一个区域的数量。S1. The VIM changes the reliability parameter according to the quantity of the at least one area and the quantity of the at least one virtual unit, and the changed reliability parameter satisfies the quantity of the at least one area.

即在本发明实例中，VIM可以自行对该可靠性参数进行修改，确定一个该VIM所管理的区域的数量满足的可靠性参数。That is, in the example of the present invention, the VIM can modify the reliability parameter by itself to determine a reliability parameter that satisfies the number of areas managed by the VIM.

具体的，VIM根据该至少一个区域的数量和该至少一个虚拟单元的数量，更改该可靠性参数的具体方法，可以参见上述S106中管理节点根据该至少一个区域的数量和该至少一个虚拟单元的数量，更改该可靠性参数的具体方法，此处不再赘述。Specifically, the specific method for the VIM to change the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit can be referred to in the above S106 by the management node according to the number of the at least one area and the at least one virtual unit. The specific method for changing the reliability parameter will not be repeated here.

进一步的，当VIM确定该更改后的可靠性参数后，即可将该更改后的可靠性参数携带在资源部署应答消息中发送至管理节点，以询问管理节点是否可以使用将该更改后的可靠性参数。Further, after the VIM determines the changed reliability parameter, it can carry the changed reliability parameter in the resource deployment response message and send it to the management node, so as to ask the management node whether the changed reliability parameter can be used. Sexual parameters.

进一步的，上述S105之后，所述方法还包括：Further, after the above S105, the method further includes:

S2、管理节点确定是否允许使用该更改后的可靠性参数。S2. The management node determines whether to allow the changed reliability parameter to be used.

示例性的，管理节点可以通过查询保存该可靠性参数的描述符中开关项是否开启，若该开关项开启，则管理节点确定允许使用该更改后的可靠性参数；若该开关项关闭，则管理节点确定不允许使用该更改后的可靠性参数。Exemplarily, the management node can query whether the switch item in the descriptor that saves the reliability parameter is turned on, if the switch item is turned on, the management node determines that the changed reliability parameter is allowed to be used; if the switch item is turned off, then The management node determines that the changed reliability parameter is not allowed.

管理节点也可以通过向网络维护人员提示该VIM发送的该更改后的可靠性参数，根据网络维护人员的指示确定是否允许使用该更改后的可靠性参数。The management node may also prompt the network maintenance personnel for the changed reliability parameters sent by the VIM, and determine whether to allow the changed reliability parameters to be used according to the instructions of the network maintenance personnel.

需要说明的是，管理节点确定是否允许使用该更改后的可靠性参数的方式，可以更具实际工程中的需要进行设置，本发明不作限制。It should be noted that the manner in which the management node determines whether to allow the use of the changed reliability parameter may be set according to actual engineering needs, which is not limited in the present invention.

S3、管理节点向VIM发送更改响应消息，该更改响应消息用于指示是否允许使用该更改后的可靠性参数。S3. The management node sends a change response message to the VIM, where the change response message is used to indicate whether the changed reliability parameter is allowed to be used.

S4、VIM接收该管理节点发送的更改响应消息。S4. The VIM receives the change response message sent by the management node.

S5、若该更改响应消息用于指示允许使用该更改后的可靠性参数，VIM则根据该更改后的可靠性参数部署所述虚拟资源。S5. If the modification response message is used to indicate that the modified reliability parameter is allowed to be used, the VIM deploys the virtual resource according to the modified reliability parameter.

另一方面，若第一资源部署请求消息的请求成功，则VIM至少可以通过如下两种方式，按照可靠性参数进行虚拟资源的部署。On the other hand, if the request of the first resource deployment request message is successful, the VIM can deploy the virtual resource according to the reliability parameter in at least the following two ways.

方式一，结合图2，如图4所示，在上述S104之前，该方法还包括：Manner 1, with reference to FIG. 2, as shown in FIG. 4, before the above S104, the method further includes:

S108、VIM根据该至少一个虚拟单元的数量和该至少一个区域，确定满足该可靠性参数且VIM允许的至少一种部署方案。S108. The VIM determines at least one deployment scheme that satisfies the reliability parameter and is allowed by the VIM according to the number of the at least one virtual unit and the at least one area.

示例性的，以可靠性参数为4，8台VM和3台主机为例。Illustratively, take the reliability parameters as 4, 8 VMs and 3 hosts as an example.

根据可靠性参数4，VIM确定在3台主机上能够成功部署8台VM的所有部署方案，该VIM允许的所有部署方案包括“044”、“134”、“224”，以及“233”。其中，由于部署方案“233”为这些部署方案中在一台主机上部署VM最少的部署方案，因此，部署方案“233”为该VIM允许的所有部署方案中可靠性最高的部署方案。According to reliability parameter 4, VIM determines all deployment scenarios that can successfully deploy 8 VMs on 3 hosts. All deployment scenarios allowed by this VIM include "044", "134", "224", and "233". Among them, since the deployment scheme "233" is the deployment scheme that deploys the fewest VMs on one host among the deployment schemes, the deployment scheme "233" is the deployment scheme with the highest reliability among all the deployment schemes allowed by the VIM.

当VIM确定满足该可靠性参数且该VIM允许的所有部署方案后，VIM即可将该所有部署方案中的至少一种部署方案携带在该资源部署应答消息中发送至管理节点。After the VIM determines all deployment schemes that satisfy the reliability parameter and are allowed by the VIM, the VIM can carry at least one deployment scheme among all the deployment schemes in the resource deployment response message and send it to the management node.

需要说明的是，至少一种部署方案可以包括该VIM允许的所有部署方案，即该VIM可以将该VIM允许的所有部署方案均携带在资源部署应答消息中发送至管理节点，以请求管理节点从该VIM允许的所有部署方案中选择一种部署方案。It should be noted that at least one deployment scheme may include all deployment schemes allowed by the VIM, that is, the VIM may carry all the deployment schemes allowed by the VIM in the resource deployment response message and send it to the management node, to request the management node from Choose one of the deployment scenarios allowed by this VIM.

至少一种部署方案可以包括该VIM允许的所有部署方案中可靠性最高的部署方案，即VIM可以先在该VIM允许的所有部署方案中选择可靠性最高的部署方案，再将该可靠性最高的部署方案携带在资源部署应答消息中发送至管理节点，以询问管理节点是否可以根据该可靠性最高的部署方案进行资源部署。At least one deployment scheme can include the deployment scheme with the highest reliability among all the deployment schemes allowed by the VIM, that is, the VIM can first select the deployment scheme with the highest reliability among all the deployment schemes allowed by the VIM, and then select the deployment scheme with the highest reliability among all the deployment schemes allowed by the VIM. The deployment scheme is carried in the resource deployment response message and sent to the management node to inquire whether the management node can deploy resources according to the deployment scheme with the highest reliability.

进一步的，在方式一中，上述S105之后，该方法还包括：Further, in the first way, after the above S105, the method further includes:

S109、管理节点从该至少一种部署方案中确定第一部署方案。S109. The management node determines a first deployment scheme from the at least one deployment scheme.

即当管理节点接收到资源部署应答消息，确定第一资源部署请求消息的请求成功，并从该资源部署应答消息中获知该VIM允许的至少一种部署方案后，管理节点可以从该至少一种部署方案中随机选择一种部署方案作为第一部署方案，也可以选择该至少一种部署方案中可靠性最高的一种部署方案作为第一部署方案，本发明不作具体限定。That is, when the management node receives the resource deployment response message, determines that the request of the first resource deployment request message is successful, and learns from the resource deployment response message at least one deployment scheme allowed by the VIM, the management node can obtain the at least one deployment scheme from the resource deployment response message. Among the deployment schemes, one deployment scheme is randomly selected as the first deployment scheme, and a deployment scheme with the highest reliability among the at least one deployment scheme may also be selected as the first deployment scheme, which is not specifically limited in the present invention.

S110、管理节点向VIM发送资源部署指示消息，该资源部署指示消息中携带该第一部署方案。S110. The management node sends a resource deployment instruction message to the VIM, where the resource deployment instruction message carries the first deployment scheme.

当管理节点从该至少一种部署方案中确定第一部署方案后，即可将该第一部署方案携带在该资源部署指示消息中发送至VIM，以指示VIM根据第一部署方案部署虚拟资源。After the management node determines the first deployment scheme from the at least one deployment scheme, the first deployment scheme can be carried in the resource deployment instruction message and sent to the VIM to instruct the VIM to deploy virtual resources according to the first deployment scheme.

S111、VIM接收管理节点发送的资源部署指示消息。S111. The VIM receives the resource deployment indication message sent by the management node.

S112、VIM根据第一部署方案在至少一个区域上部署该虚拟资源。S112. The VIM deploys the virtual resource in at least one area according to the first deployment scheme.

示例性的，结合上述S107中的举例，假设第一部署方案为“233”，则VIM即可在3台主机中的其中一台主机上部署2个VM，另外两台主机上分别部署3个VM。Exemplarily, with reference to the example in S107 above, assuming that the first deployment scheme is "233", then VIM can deploy 2 VMs on one of the 3 hosts, and deploy 3 VMs on the other two hosts respectively. VM.

方式二，结合图2，如图5所示，在上述S104之前，该方法还包括：Manner 2, with reference to FIG. 2, as shown in FIG. 5, before the above S104, the method further includes:

S108、VIM根据该至少一个虚拟单元的数量和该至少一个区域，确定满足该可靠性参数且VIM允许的至少一种部署方案。S108. The VIM determines at least one deployment scheme that satisfies the reliability parameter and is allowed by the VIM according to the number of the at least one virtual unit and the at least one area.

S113、VIM根据部署方案选择规则从该至少一种部署方案中确定第一部署方案。S113. The VIM determines a first deployment scheme from the at least one deployment scheme according to the deployment scheme selection rule.

需要说明的是，在方式二中，管理节点向VIM发送的第一资源部署请求消息中还携带部署方案选择规则，该部署方案选择规则用于VIM从至少一种部署方案中确定第一部署方案。It should be noted that, in the second mode, the first resource deployment request message sent by the management node to the VIM also carries a deployment scheme selection rule, and the deployment scheme selection rule is used by the VIM to determine the first deployment scheme from at least one deployment scheme. .

示例性的，部署方案选择规则可以为从至少一种部署方案中选择可靠性最高的部署方案，例如，如图4所示实施例中的举例，选择部署方案“233”。部署方案选择规则也可以为需要区域的个数最少的部署方案，例如，如图4所示实施例中的举例，选择部署方案“044”，在该部署方案中，仅需要两台主机即可按照可靠性参数4的要求，成功部署8台VM。Exemplarily, the deployment scheme selection rule may be to select the deployment scheme with the highest reliability from at least one deployment scheme. For example, in the example of the embodiment shown in FIG. 4 , the deployment scheme "233" is selected. The deployment scheme selection rule can also be the deployment scheme that requires the least number of areas. For example, in the example shown in the embodiment shown in Figure 4, the deployment scheme "044" is selected. In this deployment scheme, only two hosts are required. According to the requirements of reliability parameter 4, 8 VMs were successfully deployed.

S 114、VIM根据第一部署方案在至少一个区域上部署该虚拟资源。S114. The VIM deploys the virtual resource on at least one area according to the first deployment scheme.

进一步的，当VIM根据该第一部署方案完成虚拟资源的部署后，即可向管理节点发送资源部署应答消息，以指示管理节点该第一资源部署请求消息的请求成功。Further, after the VIM completes the deployment of the virtual resources according to the first deployment scheme, it can send a resource deployment response message to the management node to indicate that the management node has successfully requested the first resource deployment request message.

值得说明的是，本发明提供的虚拟资源的部署方法，可以应用于多种应用场景中，例如VNF的实例化，NS的实例化，VNF的扩展过程，NS的扩展，VNF的迁移，以及NS的迁移等场景，这些场景中均包括虚拟资源的部署过程。It is worth noting that the method for deploying virtual resources provided by the present invention can be applied to various application scenarios, such as VNF instantiation, NS instantiation, VNF expansion process, NS expansion, VNF migration, and NS migration and other scenarios, all of which include the deployment process of virtual resources.

其中，虚拟资源的部署可以是虚拟资源的预留，虚拟资源的分配，或者虚拟资源的迁移。The deployment of virtual resources may be reservation of virtual resources, allocation of virtual resources, or migration of virtual resources.

进一步的，若虚拟资源的部署具体指虚拟资源的分配，则上述第一资源部署请求消息具体为第一资源分配请求消息，且该第一资源分配请求消息用于请求VIM分配该虚拟资源；若虚拟资源的部署具体指虚拟资源的预留，则上述第一资源部署请求消息具体为第一资源预留请求消息，且该第一资源预留请求消息用于请求VIM预留该虚拟资源；若虚拟资源的部署具体指虚拟资源的迁移，则上述第一资源部署请求消息具体为第一资源迁移请求消息，且该第一资源迁移请求消息用于请求VIM将该虚拟资源迁移到该VIM管理的至少一个区域上。Further, if the deployment of virtual resources specifically refers to the allocation of virtual resources, the above-mentioned first resource deployment request message is specifically a first resource allocation request message, and the first resource allocation request message is used to request the VIM to allocate the virtual resource; if The deployment of virtual resources specifically refers to the reservation of virtual resources, and the above-mentioned first resource deployment request message is specifically a first resource reservation request message, and the first resource reservation request message is used to request the VIM to reserve the virtual resource; if The deployment of virtual resources specifically refers to the migration of virtual resources, and the above-mentioned first resource deployment request message is specifically a first resource migration request message, and the first resource migration request message is used to request the VIM to migrate the virtual resource to the management of the VIM. in at least one area.

需要说明的是，由于在VNF的实例化过程或者VNF的扩展过程中，可以由VNFM向VIM发送资源分配请求消息，请求VIM为VNF分配虚拟资源，因此，当本发明实施例提供的虚拟资源的部署方法，应用于VNF的实例化过程或者VNF的扩展过程中，且虚拟资源的部署具体指虚拟资源的分配时，管理节点可以为VNFM。It should be noted that, since the VNFM may send a resource allocation request message to the VIM during the VNF instantiation process or the VNF expansion process, requesting the VIM to allocate virtual resources to the VNF, therefore, when the virtual resources provided by the embodiments of the present invention are The deployment method is applied to the instantiation process of the VNF or the expansion process of the VNF, and when the deployment of virtual resources specifically refers to the allocation of virtual resources, the management node may be a VNFM.

特别的，当管理节点为VNFM时，VNFM可以具备更改可靠性参数的功能，从而当第一资源分配请求消息的请求失败时，VNFM可以自行更改可靠性参数。当然，VNFM也可以不具备更改可靠性参数的功能，从而当第一资源分配请求消息的请求失败时，VNFM可以请求NFVO对可靠性参数进行更改。Particularly, when the management node is a VNFM, the VNFM may have the function of changing the reliability parameter, so that when the request of the first resource allocation request message fails, the VNFM may change the reliability parameter by itself. Of course, the VNFM may not have the function of changing the reliability parameter, so when the request of the first resource allocation request message fails, the VNFM may request the NFVO to change the reliability parameter.

可以理解的是，若描述符中设置有开关项，则NFVO接收到VNFM的请求，对可靠性参数进行修改前，先查询该开关项是否开启，并在开关型开启的时候，响应VNFM的请求，对可靠性参数进行修改。It can be understood that if a switch item is set in the descriptor, NFVO receives the VNFM request, and before modifying the reliability parameter, it first checks whether the switch item is enabled, and responds to the VNFM request when the switch type is enabled. , modify the reliability parameters.

具体的，如图6所示，当VNFM不具备更改可靠性参数的功能时，且在第一资源分配请求消息的请求失败的情况下，本发明实施例提供的虚拟资源部署的方法可以包括：Specifically, as shown in FIG. 6, when the VNFM does not have the function of changing the reliability parameter, and in the case that the request of the first resource allocation request message fails, the method for deploying virtual resources provided by the embodiment of the present invention may include:

S201、VNFM向VIM发送第一资源分配请求消息，该第一资源分配请求消息中携带可靠性参数。S201. The VNFM sends a first resource allocation request message to the VIM, where the first resource allocation request message carries a reliability parameter.

S202、VIM接收VNFM发送的第一资源分配请求消息。S202. The VIM receives the first resource allocation request message sent by the VNFM.

S203、VIM根据该可靠性参数，该VIM所管理的至少一个区域的数量，以及该至少一个虚拟单元的数量，确定该第一资源分配请求消息的请求失败。S203. The VIM determines that the request for the first resource allocation request message fails according to the reliability parameter, the number of at least one area managed by the VIM, and the number of the at least one virtual unit.

S204、VIM向VNFM发送资源部署应答消息，该资源部署应答消息用于指示所述第一资源分配请求消息的请求失败，该资源部署应答消息中携带该至少一个区域的数量。S204. The VIM sends a resource deployment response message to the VNFM, where the resource deployment response message is used to indicate that the request of the first resource allocation request message fails, and the resource deployment response message carries the quantity of the at least one area.

S205、VNFM接收VIM发送的资源部署应答消息。S205. The VNFM receives the resource deployment response message sent by the VIM.

S206、VNFM向NFVO发送该至少一个区域的数量和该至少一个虚拟单元的数量。S206. The VNFM sends the quantity of the at least one area and the quantity of the at least one virtual unit to the NFVO.

其中，VNFM可以将该至少一个区域的数量和该至少一个虚拟单元的数量携带在VNFM和VNFO之间进行信息传输的消息中发送至NFVO。Wherein, the VNFM may carry the quantity of the at least one area and the quantity of the at least one virtual unit in a message for information transmission between the VNFM and the VNFO, and send it to the NFVO.

S207、NFVO根据该至少一个区域的数量和该至少一个虚拟单元的数量，更改该可靠性参数。S207. NFVO changes the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit.

S208、NFVO向VNFM发送更改后的可靠性参数。S208. The NFVO sends the changed reliability parameter to the VNFM.

S209、VNFM接收到NFVO发送的更改后的可靠性参数后，向VIM发送第二资源分配请求消息，该第二资源分配请求消息中携带该更改后的可靠性参数。S209. After receiving the changed reliability parameter sent by the NFVO, the VNFM sends a second resource allocation request message to the VIM, where the second resource allocation request message carries the changed reliability parameter.

进而，当VIM接收到第二资源分配请求消息后，即可按照更改后的可靠性参数进行虚拟资源的部署。可以理解的是，由于修改后的可靠性参数满足该VIM所管理的区域的数量，因此，VIM可以成功按照修改后的可靠性参数进行虚拟资源的部署。Furthermore, after the VIM receives the second resource allocation request message, the virtual resource can be deployed according to the changed reliability parameter. It can be understood that since the modified reliability parameter satisfies the number of areas managed by the VIM, the VIM can successfully deploy virtual resources according to the modified reliability parameter.

本发明实例提供一种虚拟资源的部署方法，管理节点能够将可靠性参数携带在第一资源部署请求消息中，由于该可靠性参数表征了在一个区域内允许部署的虚拟单元的最大数量，因此VIM VIM接收到第一资源部署请求消息后，可以确定在一个区域内能够部署的虚拟单元的最大数量，并按照该可靠性参数进行虚拟资源的部署，进而避免了现有技术中VIM可能将所有的虚拟资源部署在一个区域上，进行提高了资源部署的可靠性。An example of the present invention provides a method for deploying virtual resources. The management node can carry the reliability parameter in the first resource deployment request message. Since the reliability parameter represents the maximum number of virtual units allowed to be deployed in an area, therefore VIM After VIM receives the first resource deployment request message, it can determine the maximum number of virtual units that can be deployed in an area, and deploy virtual resources according to the reliability parameter, thereby avoiding the possibility of VIM in the prior art The virtual resources are deployed in one area, which improves the reliability of resource deployment.
