In this application.
技术领域Technical field
本发明涉及通信技术领域，特别涉及一种资源申请、VNF实例创建方法及装置。The present invention relates to the field of communications technologies, and in particular, to a resource application, a VNF instance creation method and apparatus.
背景技术Background technique
传统的电信***通过各种专用的硬件设备组成，不同的应用采用不同的硬件设备。随着网络规模的增长，***越来越复杂，带来了诸多的挑战，包括新增业务的开发上线、***的运维、资源利用率等。为了应对这些挑战及利用IT业界的虚拟化技术及云计算技术，在2012年10月22日召开的“SDN and OpenFlow World Congress”会议上，全球主要的13个电信运营商联合发布了网络功能虚拟化(Network Functions Virtualization，NFV)***，并宣布在ETSI成立NFV ISG，制定NFV的需求及技术框架。The traditional telecommunication system is composed of various dedicated hardware devices, and different applications use different hardware devices. As the scale of the network grows, the system becomes more and more complex, which brings many challenges, including the development of new services, the operation and maintenance of the system, and resource utilization. In response to these challenges and the use of virtualization technology and cloud computing technology in the IT industry, at the "SDN and OpenFlow World Congress" conference held on October 22, 2012, the world's 13 major telecom operators jointly released network function virtualization. Network Functions Virtualization (NFV) white paper, and announced the establishment of NFV ISG at ETSI to develop NFV requirements and technical framework.
NFV ISG定义的网络功能虚拟化(Network Functions Virtualization，NFV)的框架中包括：NFV管理和编排***(NFV Management and Orchestration，NFV MANO)、NFV基础设施层(NFV Infrastructure，NFVI)、多个虚拟网络功能(Virtual Network Function，VNF)、多个网元管理(Element Management，EM)、网络服务、VNF和基础设施描述(Network Service,VNF and Infrastructure Description)，以及业务支持管理***(Operation-Support System/Business Support System，OSS/BSS)。其中，NFV管理和编排***包括NFV编排器(NFV Orchestrator，NFVO)，一个或多个VNF管理器(VNF Manager，VNFM)和虚拟化基础设施管理器(Virtualized Infrastructure Manager，VIM)。The NFV ISG defines the Network Functions Virtualization (NFV) framework: NFV Management and Orchestration (NFV MANO), NFV Infrastructure (NFV), and multiple virtual networks. Virtual Network Function (VNF), Multiple Element Management (EM), Network Services, VNF and Network Service (VNF and Infrastructure Description), and Operation Support System (Operation-Support System/) Business Support System, OSS/BSS). Among them, the NFV management and orchestration system includes NFV Orchestrator (NFVO), one or more VNF Manager (VNFM) and Virtualized Infrastructure Manager (VIM).
由上述架构可知，NFV中没有独享的物理资源，因此虚拟资源的申请和释放是NFV规范中比较重要的内容。在ETSI NFV标准中，现在定义的虚拟资源的申请和释放的流程是通过NFVO/VNFM和VIM之间的交互来实现的，而每个VNF对于资源的需求是通过一个事先定义好的VNFD文件来描述，由MANO(NFVO和VNFM)根据VNFD文件向VIM申请资源。由于VNFD文件是事先准备好的，若资源需求发生变化，则会导致VNFD文件无法满足这一需求。It can be seen from the above architecture that there is no exclusive physical resource in the NFV, so the application and release of the virtual resource is a relatively important content in the NFV specification. In the ETSI NFV standard, the process of applying and releasing virtual resources defined now is implemented through the interaction between NFVO/VNFM and VIM, and each VNF needs resources through a predefined VNFD file. Description, MANO (NFVO and VNFM) apply for resources from VIM based on the VNFD file. Since the VNFD file is prepared in advance, if the resource requirements change, the VNFD file will not meet this requirement.
综上，目前亟需一种资源申请方法，用于解决现有技术中根据事先准备好的VNFD文件进行资源申请无法满足动态变化的资源需求的技术问题。To sum up, there is a need for a resource application method for solving the technical problem that the resource application according to the previously prepared VNFD file cannot meet the dynamically changing resource requirement in the prior art.

The VNFM 104 and VIM 106 can communicate with one another for resource allocation and exchange of configuration and status information for virtualized hardware resources.
所述NFVI 130包括硬件资源、软件资源或两者的组合来完成虚拟化环境的部署。换句话说，硬件资源和虚拟化层用于提供虚拟化的资源，例如作为虚拟机和其它形式的虚拟容器，用于VNF 108。硬件资源包括计算硬件112、存储硬件114和网络硬件116。计算硬件112可以是市场上现成的硬件和/或用户定制的硬件，用来提供处理和计算资源。存储硬件114可以是网络内提供的存储容量或驻留在存储硬件114本身的存储容量(位于服务器内的本地存储器)。在一种可能的实现方案中，计算硬件112和存储硬件114的资源可以被集中在一起。网 络硬件116可以是交换机、路由器和/或配置成具有交换功能的任何其他网络设备。网络硬件116可以横跨多个域，并且可以包括多个由一个或一个以上传输网络互连的网络。The NFVI 130 includes hardware resources, software resources, or a combination of both to complete the deployment of the virtualized environment. In other words, the hardware resources and virtualization layers are used to provide virtualized resources, such as virtual machines and other forms of virtual containers, for VNF 108. Hardware resources include computing hardware 112, storage hardware 114, and network hardware 116. Computing hardware 112 may be off-the-shelf hardware and/or user-customized hardware used to provide processing and computing resources. Storage hardware 114 may be storage capacity provided within the network or storage capacity resident in storage hardware 114 itself (local storage located within the server). In one possible implementation, the resources of computing hardware 112 and storage hardware 114 can be grouped together. Network hardware 116 can be a switch, a router, and/or any other network device configured to have switching functionality. Network hardware 116 can span multiple domains and can include multiple networks interconnected by one or more transport networks.
NFVI 130里面的虚拟化层可以从物理层抽象硬件资源和解耦VNF 108，以便向VNF 108提供虚拟化资源。虚拟资源层包括虚拟计算110，虚拟存储118和虚拟网络120。虚拟计算110和虚拟存储118可以以虚拟机、和/或其他虚拟容器的形式提供给VNF 108。例如，一个或一个以上的VNF 108可以部署在一个虚拟机(Virtual Machine)上。虚拟化层抽象网络硬件116从而形成虚拟网络120，虚拟网络120可以包括虚拟交换机(Virtual Switch)，所述虚拟交换机用来提供虚拟机和其他虚拟机之间的连接。此外，网络硬件116中的传输网络，可以采用集中式控制平面和一个单独的转发平面(如软件定义网络，SDN)虚拟化。The virtualization layer within NFVI 130 can abstract hardware resources from the physical layer and decouple VNF 108 to provide virtualized resources to VNF 108. The virtual resource layer includes virtual computing 110, virtual storage 118, and virtual network 120. Virtual computing 110 and virtual storage 118 may be provided to VNF 108 in the form of virtual machines, and/or other virtual containers. For example, one or more VNFs 108 can be deployed on a virtual machine. The virtualization layer abstracts network hardware 116 to form a virtual network 120, which may include a virtual switch that is used to provide connectivity between virtual machines and other virtual machines. In addition, the transport network in network hardware 116 can be virtualized using a centralized control plane and a separate forwarding plane (eg, software defined network, SDN).

The VNF 108 can be configured to virtualize at least one network function performed by one physical network device. For example, in a possible implementation, the VNF 108 can be configured to provide functions of different network elements in the IMS network, such as Proxy Call Session Control Function (P-CSCF), service. The network function of the Serving Call Session Control Function (S-CSCF) or the Home Subscriber Server (HSS). The EM 122 is configured to manage one or more VNFs 108.
基于上述***架构，图2为由NFVO发起的VNF部署实例化的流程图，此流程的主要步骤如下：Based on the above system architecture, Figure 2 is a flow chart of instantiation of VNF deployment initiated by NFVO. The main steps of this process are as follows:
步骤201，NFVO收到实例化VNF的请求(此请求可能是维护人员手工发起，或者是通过OSS/BSS自动发起)；Step 201, the NFVO receives the request to instantiate the VNF (this request may be initiated manually by the maintenance personnel, or automatically initiated by the OSS/BSS);
步骤202，NFVO请求VNFM发起实例化VNF的操作，在此请求中包含了VNF实例化所需要的信息；Step 202, the NFVO requests the VNFM to initiate an operation of instantiating the VNF, where the request includes information required for VNF instantiation;
步骤203，VNFM请求NFVO准许根据VNFD中描述的资源信息，实例化VNF所需的资源；Step 203: The VNFM requests the NFVO to authorize the resources required by the VNF according to the resource information described in the VNFD.
以下是一个简单的VNFD文件描述的片段实例：The following is an example of a fragment of a simple VNFD file description:
Figure PCTCN2018077067-appb-000001
Figure PCTCN2018077067-appb-000001
Figure PCTCN2018077067-appb-000002
Figure PCTCN2018077067-appb-000002
此VNFD中描述VNF所需要的CPU、存储资源，以及镜像文件；NFVO/VNFM即根据此VNFD文件进行虚拟资源的申请；This VNFD describes the CPU, storage resources, and image files required by the VNF; NFVO/VNFM applies for virtual resources based on this VNFD file;
步骤204，NFVO检查实例化VNF所需要的资源的满足情况；Step 204, the NFVO checks the satisfaction of the resources required to instantiate the VNF;
步骤205至步骤206，可选地，NFVO可以到VIM去预留实例化VNF所需要的资源；Step 205 to step 206, optionally, the NFVO may go to the VIM to reserve the resources required to instantiate the VNF;
步骤207，作为对于步骤203的响应，NFVO将VIM的标识通知给VNFM，以便VNFM去申请虚拟化资源，如果NFVO执行过步骤205和步骤206，NFVO也会将资源预留的相关信息通知给VNFM；Step 207: In response to step 203, the NFVO notifies the VNFM of the VIM, so that the VNFM requests the virtualized resource. If the NFVO performs steps 205 and 206, the NFVO also notifies the VNFM of the resource reservation related information. ;
步骤208，VNFM根据收到的VIM标识，发送请求给VIM去申请虚拟资源，创建和启动虚拟机VMs；VNF实例化所需的资源需求是在VNFD文件中描述；Step 208: The VNFM sends a request to the VIM to apply for the virtual resource according to the received VIM identifier, and creates and starts the virtual machine VMs. The resource requirements required for the VNF instantiation are described in the VNFD file.
步骤209，VIM根据VNFM的请求创建和启动虚拟机，以及相应的网络资源，回送成功响应给VNFM；Step 209: The VIM creates and starts a virtual machine according to the request of the VNFM, and corresponding network resources, and sends a successful response to the VNFM.
步骤210，虚拟机创建完成以后，VNFM可以对于VNF做一些VNF特有的配置；Step 210: After the virtual machine is created, the VNFM may perform some VNF-specific configurations for the VNF.
步骤211，VNFM通知EM一个新的VNF实例已经被创建；Step 211, the VNFM notifies the EM that a new VNF instance has been created;
步骤212，EM和VNFM添加新的VNF实例为管理对象；Step 212: EM and VNFM add a new VNF instance as a management object;
步骤213，EM可以对于VNF做上层应用配置；Step 213, the EM can perform upper layer application configuration for the VNF;
步骤214，作为对于步骤202的回应，VNFM通知NFVO VNF实例化已成功完成；Step 214, in response to step 202, the VNFM notifies that the NFVO VNF instantiation has been successfully completed;
步骤215，NFVO将VNF映射到正确的VIM资源池模型；Step 215, NFVO maps the VNF to the correct VIM resource pool model;
在以上步骤中，涉及资源申请和释放的流程主要是步骤203至步骤209，可以看出所有的资源管理都是通过NFVO/VNFM与VIM的交互来完成的，而具体资源的需求(CPU，内存，网络等)是通过VNFD文件描述的，NFVO/VNFM通过解析事先准备好的VNFD文件得到一个VNF所需要的资源，NFVO/VNFM在申请资源的过程中(步骤203至步骤209)与VNF之间不存在交互。然而，针对一些资源需求不断变化的场景，例如，灰度升级过程，若仍采用事先准备好的VNFD文件来进行资源申请，则难以适用资源需求的动态变化。In the above steps, the process involving resource application and release is mainly steps 203 to 209. It can be seen that all resource management is completed by the interaction of NFVO/VNFM and VIM, and the requirements of specific resources (CPU, memory). , network, etc.) is described by the VNFD file. NFVO/VNFM obtains the resources required by a VNF by parsing the prepared VNFD file. NFVO/VNFM is in the process of applying for resources (steps 203 to 209) and VNF. There is no interaction. However, for some scenarios where resource requirements are constantly changing, for example, the grayscale upgrade process, if a previously prepared VNFD file is still used for resource application, it is difficult to apply dynamic changes in resource requirements.
基于此，本发明实施例提供一种资源申请方法，用以解决现有技术中根据事先准备好的VNFD文件进行资源申请无法满足动态变化的资源需求的技术问题。Based on this, the embodiment of the present invention provides a resource application method, which is used to solve the technical problem that the resource application cannot meet the dynamically changing resource requirement according to the prepared VNFD file in the prior art.
本发明实施例中的资源申请方法可适用于多种场景中，尤其适用于灰度升级场景。灰度升级是在黑与白之间，能够平滑过渡的一种发布方式，例如，AB版本测试就是一种灰度发布方式，具体来说，让一部分用户继续用版本A，一部分用户开始用版本B，如果使用版本B的用户对版本B无反对意见，则可逐步扩大范围，把所有用户都迁移到版本B。由此可知，采用这种发布方式，可以保证整体***的稳定，而且，在初始灰度时能够及时发现和调整问题，以保证其影响度。如此，若在NFV中应用灰度升级，由于VNF的AB版本同时存在，则可能会涉及到对已有资源的动态调整，具体来说，由于升级过程中灰度用户的比例会不断发生变化，很可能对于资源的需求就不断发生变化，例如，开始仅对几个友好用户开通业务进行测试，只需要很少的资源，慢慢再对某个区域，某几个区域开通业务进行测试，从而使得资源需求不断变化。The resource application method in the embodiment of the present invention can be applied to various scenarios, and is particularly applicable to a grayscale upgrade scenario. Grayscale upgrade is a release method that can smoothly transition between black and white. For example, the AB version test is a grayscale publishing method. Specifically, some users continue to use version A, and some users start using the version. B. If users using version B have no objection to version B, they can gradually expand the scope and migrate all users to version B. It can be seen from this that the release mode can ensure the stability of the overall system, and the problem can be discovered and adjusted in time in the initial gray scale to ensure its influence. Thus, if grayscale upgrade is applied in NFV, since the AB version of VNF exists at the same time, it may involve dynamic adjustment of existing resources. Specifically, the proportion of grayscale users will constantly change during the upgrade process. It is very likely that the demand for resources will continue to change. For example, starting testing only a few friendly users, only a small amount of resources are needed, and then a certain area and a certain area are opened for testing. Make resource requirements constantly changing.
根据上述内容可知，在NFV下的VNF灰度升级过程中，存在着不同的灰度策略、级别和范围，对于资源的需求可能是动态变化的，通过事先指定VNFD进行资源申请的方式不太容易满足这个动态变化的要求，因此，本发明实施例通过MANO在资源管理过程中增加和VNF交互 的方式，来动态的进行资源申请，相当于动态的生成VNFD，满足VNF灰度升级过程中资源需求的动态变化。According to the above, in the VNF grayscale upgrade process under NFV, there are different grayscale strategies, levels and ranges, and the demand for resources may be dynamically changed. It is not easy to specify the VNFD for resource application in advance. The requirements of this dynamic change are met. Therefore, the embodiment of the present invention dynamically requests the resource by adding a VNF interaction in the resource management process, which is equivalent to dynamically generating the VNFD to meet the resource requirements in the VNF grayscale upgrade process. Dynamic changes.
实施例一 Embodiment 1
基于上述***结构，图3为本发明实施例一提供的资源申请方法对应的流程示意图。如图3所示，该方法包括：Based on the above system structure, FIG. 3 is a schematic flowchart of a resource application method according to Embodiment 1 of the present invention. As shown in FIG. 3, the method includes:
步骤301，VNF确定待申请资源的数量； Step 301, the VNF determines the quantity of resources to be applied;
步骤302，VNF向VNFM发送资源申请消息，所述资源申请消息用于所述VNFM根据所述待申请资源的数量进行资源申请；Step 302: The VNF sends a resource application message to the VNFM, where the resource application message is used by the VNFM to perform resource application according to the quantity of the to-be-applied resource;
步骤303，VNFM接收VNF发送的资源申请消息；Step 303: The VNFM receives the resource application message sent by the VNF.
步骤304，VNFM根据所述待申请资源的数量进行资源申请；Step 304: The VNFM performs a resource application according to the quantity of the to-be-applied resources;
步骤305，VNFM向所述VNF发送申请响应消息，所述申请响应消息为资源申请成功响应或资源申请失败响应；Step 305: The VNFM sends an application response message to the VNF, where the application response message is a resource application success response or a resource application failure response.
步骤306，VNF接收所述VNFM返回的申请响应消息。Step 306: The VNF receives an application response message returned by the VNFM.
由此可知，本发明实施例中在资源申请过程中，引入了VNF和VNFM之间的交互，由于VNF能够根据资源需求，灵活确定待申请资源的数量，从而使得VNFM申请的资源能够灵活满足资源需求的动态变化；且，由于待申请资源的数量是由VNF动态生成的，相对于现有技术中事先通过人工准备VNFD的方式更加便捷可行。Therefore, in the embodiment of the present invention, the interaction between the VNF and the VNFM is introduced in the resource application process. The VNF can flexibly determine the quantity of the resource to be applied according to the resource requirement, so that the VNFM application resource can flexibly satisfy the resource. Dynamic changes in demand; and, since the number of resources to be applied is dynamically generated by the VNF, it is more convenient and feasible to manually prepare the VNFD in advance than in the prior art.
为对上述过程进行具体说明，下面以灰度升级场景为例，结合图4进行详细描述。In order to specifically describe the above process, the grayscale upgrade scenario is taken as an example and described in detail in conjunction with FIG. 4.
步骤401，升级管理向VNF下发灰度升级任务开始的灰度升级请求消息，灰度升级请求消息中可以包含灰度升级的不同阶段，以及对应的灰度策略；比如，灰度阶段1：有10％的用户使用新版本；灰度阶段2：有50％的用户使用新版本，最终阶段全部用户使用新版本。Step 401: The upgrade management sends a grayscale upgrade request message to the VNF to start the grayscale upgrade task, and the grayscale upgrade request message may include different stages of the grayscale upgrade and the corresponding grayscale policy; for example, the grayscale phase 1: 10% of users use the new version; gray level 2: 50% of users use the new version, and all users use the new version in the final stage.
需要说明的是：本发明实施例中的升级管理为一个逻辑功能实体，用来控制和协调整个灰度升级的过程，反馈不同阶段的结果。升级管理程序可以部署在不同的功能节点上，比如，部署在EM、NFVO、VNFM、或者VNF，具体不做限制。It should be noted that the upgrade management in the embodiment of the present invention is a logical functional entity, which is used to control and coordinate the entire grayscale upgrade process, and feedback the results of different phases. The upgrade management program can be deployed on different functional nodes, for example, deployed in EM, NFVO, VNFM, or VNF, without limitation.
步骤402，VNF收到灰度升级任务和灰度策略以后，根据当前所处的阶段，计算额外所需要的灰度资源(即确定待申请资源的数量)；举例来说，假设灰度阶段1有10％的用户需要升级新版本处理，在VNF现有资源基础上，需要额外4个业务处理单元来处理，则需要新增4个某类型的虚拟机。Step 402: After receiving the grayscale upgrade task and the grayscale policy, the VNF calculates additional required grayscale resources according to the current phase (ie, determines the number of resources to be applied); for example, assumes that the grayscale phase 1 10% of users need to upgrade the new version. On the basis of VNF's existing resources, an additional 4 service processing units are required for processing. Four new types of virtual machines need to be added.
步骤403，VNF向VNFM发送资源确认消息，所述资源确认消息中包括待申请资源的数量，以便于向VNFM确认是否可以满足资源要求。Step 403: The VNF sends a resource confirmation message to the VNFM, where the resource confirmation message includes the number of resources to be applied, so as to confirm whether the resource requirement can be met to the VNFM.
步骤404，VNFM向NFVO发送确认消息，确认是否可以满足资源要求。In step 404, the VNFM sends an acknowledgement message to the NFVO to confirm whether the resource requirement can be met.
步骤405至步骤408，与图2中所描述的现有流程类似，NFVO确定当前的资源是否能满足VNFM发送的资源请求，并返回结果给VNFM；可选的步骤，NFVO可以到VIM去预留资源；Step 405 to step 408, similar to the existing process described in FIG. 2, the NFVO determines whether the current resource can satisfy the resource request sent by the VNFM, and returns the result to the VNFM; in an optional step, the NFVO can go to the VIM to reserve Resource
步骤409，作为对于步骤403的响应，VNFM向VNF返回对于灰度资源确认的结果；Step 409, as a response to step 403, the VNFM returns a result for the grayscale resource confirmation to the VNF;
步骤410，VNF根据VNFM返回的结果确定下一步的动作，例如，若当前资源可以满足要求，则VNF可以进一步请求VNFM创建新的虚拟资源，并执行步骤411；若当前资源不能满足要求，则VNF需要调整灰度策略(比如降低灰度用户的比例，即降低待申请资源的数量)，或者返回结果给升级管理，由操作员人工干预(比如降低灰度用户比例)。Step 410: The VNF determines the next action according to the result returned by the VNFM. For example, if the current resource can meet the requirement, the VNF may further request the VNFM to create a new virtual resource, and perform step 411; if the current resource cannot meet the requirement, the VNF Need to adjust the grayscale strategy (such as reducing the proportion of grayscale users, that is, reducing the number of resources to be applied), or return the results to the upgrade management, manually intervention by the operator (such as reducing the proportion of grayscale users).
步骤411至步骤412，VNFM到VIM去申请虚拟资源并得到结果。Step 411 to step 412, the VNFM goes to the VIM to apply for the virtual resource and obtain the result.
步骤413，作为对于步骤410的响应，VNFM将虚拟资源申请结果发送给VNF。Step 413, in response to step 410, the VNFM sends the virtual resource application result to the VNF.
步骤414，VNF可将灰度资源申请结果发送给升级管理。In step 414, the VNF may send the grayscale resource application result to the upgrade management.
步骤415，升级管理开始启动对应的后续灰度升级的流程处理。In step 415, the upgrade management starts to start the process processing of the corresponding subsequent grayscale upgrade.
本发明实施例侧重于灰度升级中资源的管理，灰度升级的流程本身与现有流程相同，此处不做详细描述。The embodiment of the present invention focuses on the management of resources in the grayscale upgrade, and the process of the grayscale upgrade itself is the same as the existing process, and will not be described in detail herein.
步骤416至步骤417，当前阶段的灰度升级完成以后，开始进行当前阶段的灰度测试验证，VNF将灰度验证的结果上报给升级管理；Step 416 to step 417, after the gray level upgrade of the current stage is completed, the gray level test verification of the current stage is started, and the VNF reports the result of the gray level verification to the upgrade management;
步骤418至步骤419，升级管理启动灰度升级的下一个阶段；Step 418 to step 419, the upgrade management starts the next stage of the grayscale upgrade;
步骤420，VNF根据新阶段的灰度策略(比如此阶段需要50％的用户使用新版本)计算所额外需要的虚拟资源，即重复上述步骤402至步骤413的流程。In step 420, the VNF calculates the additionally required virtual resources according to the gray policy of the new stage (for example, 50% of the users need to use the new version at this stage), that is, repeats the processes of steps 402 to 413 described above.
在上述过程中，升级管理向VNF灰度升级请求消息，由VNF根据灰度升级请求消息确定出待申请资源的数量，并由VNFM基于确定出的待申请资源的数量进行资源申请，通过在资源申请过程中引入VNF和VNFM的交互，实现了灰度升级过程中动态确定需要申请的资源，有效解决了资源需求不断变化的问题。In the above process, the upgrade management sends a request message to the VNF grayscale upgrade request, and the VNF determines the number of resources to be applied according to the grayscale upgrade request message, and the VNFM performs resource application based on the determined number of resources to be applied, and passes the resource in the resource. The interaction between VNF and VNFM is introduced during the application process, which realizes the dynamic determination of the resources that need to be applied during the grayscale upgrade process, and effectively solves the problem of constantly changing resource requirements.

The VNF can flexibly determine the quantity of the resource to be applied according to the resource requirement, and generate a VNFD file, so that the VNFM application resource can flexibly satisfy the resource. Dynamic changes in demand; and, since the VNFD file is dynamically generated by the VNF, it is more convenient and feasible to manually prepare the VNFD file in advance than in the prior art.
为对上述过程进行具体说明，下面以灰度升级场景为例，结合图6进行详细描述。In order to specifically describe the above process, the grayscale upgrade scenario is taken as an example and described in detail with reference to FIG. 6.
本发明实施例中，图6中所示出的方案和图4中所示出的方案类似，不同之处在于灰度升级初始的第一阶段，VNF根据灰度策略计算灰度资源以后，根据灰度资源情况直接生成一个新的VNFD，上传到VNFM，并请求VNFM按照此VNFD部署一个新的灰度VNF实例，因此，图6中所示出的方案适用于需要创建一个额外的VNF灰度实例的场景。In the embodiment of the present invention, the scheme shown in FIG. 6 is similar to the scheme shown in FIG. 4, except that the first stage of the grayscale upgrade is initial, after the VNF calculates the grayscale resource according to the grayscale policy, according to The grayscale resource situation directly generates a new VNFD, uploads it to VNFM, and requests VNFM to deploy a new grayscale VNF instance according to this VNFD. Therefore, the scheme shown in Figure 6 is suitable for creating an additional VNF grayscale. The scenario of the instance.
步骤601，升级管理给VNF下发灰度升级任务开始的灰度升级请求消息请求，灰度升级请求消息中可以包含灰度升级的不同阶段，以及对应的灰度策略；比如，灰度阶段1：有10％的用户使用新版本；灰度阶段2：有50％的用户使用新版本，最终阶段全部用户使用新版本。Step 601, the upgrade management sends a grayscale upgrade request message request to the VNF to issue a grayscale upgrade task, and the grayscale upgrade request message may include different stages of grayscale upgrade, and corresponding grayscale policies; for example, grayscale phase 1 : 10% of users use the new version; gray level 2: 50% of users use the new version, and all users use the new version in the final stage.
需要说明的是：本发明实施例中的升级管理为一个逻辑功能实体，用来控制和协调整个 灰度升级的过程，反馈不同阶段的结果。升级管理程序可以部署在不同的功能节点上，比如，部署在EM、NFVO、VNFM、或者VNF，具体不做限制。It should be noted that the upgrade management in the embodiment of the present invention is a logical functional entity, which is used to control and coordinate the entire grayscale upgrade process, and feedback the results of different phases. The upgrade management program can be deployed on different functional nodes, for example, deployed in EM, NFVO, VNFM, or VNF, without limitation.
步骤602，VNF收到灰度升级任务和灰度策略以后，根据当前所处的阶段，计算所额外需要的灰度资源(即确定待申请资源的数量)，并根据灰度升级所需要的资源要求，生成一个新的VNFD文件。Step 602: After receiving the grayscale upgrade task and the grayscale policy, the VNF calculates the additional required grayscale resources (that is, determines the number of resources to be applied) according to the current stage, and upgrades the required resources according to the grayscale. Request to generate a new VNFD file.
步骤603，VNF向VNFM发送实例创建消息，用于将新的VNFD文件上传给VNFM，并请求VNFM根据新的VNFD文件部署一个新的灰度VNF实例。Step 603: The VNF sends an instance creation message to the VNFM for uploading the new VNFD file to the VNFM, and requests the VNFM to deploy a new grayscale VNF instance according to the new VNFD file.
步骤604，VNFM向NFVO发送确认消息，确认是否可以满足资源要求。In step 604, the VNFM sends an acknowledgement message to the NFVO to confirm whether the resource requirement can be met.
步骤605至步骤610，与图2中所描述的现有流程类似，NFVO确定当前的资源是否能满足VNFM发送的资源请求，并返回结果给VNFM；可选的步骤，NFVO可以到VIM去预留资源；VNFM到VIM去申请资源创建一个新的VNF实例。Step 605 to step 610, similar to the existing process described in FIG. 2, the NFVO determines whether the current resource can satisfy the resource request sent by the VNFM, and returns the result to the VNFM; in an optional step, the NFVO can go to the VIM to reserve Resources; VNFM to VIM to apply for resources to create a new VNF instance.
步骤611，VNFM将创建VNF实例的结果通知给VNF。In step 611, the VNFM notifies the VNF of the result of creating the VNF instance.
步骤612，VNF根据VNFM返回的结果确定下一步的动作，例如，若当前灰度VNF实例创建成功，则可通知升级管理灰度资源申请完成，并执行步骤613；若当前灰度VNF实例创建不成功，则VNF需要调整灰度策略(比如降低灰度用户的比例)，或者返回结果给升级管理，由操作员人工干预(比如降低灰度用户比例)。Step 612, the VNF determines the next action according to the result returned by the VNFM. For example, if the current grayscale VNF instance is successfully created, the upgrade management grayscale resource application completion may be notified, and step 613 is performed; if the current grayscale VNF instance is created, If successful, the VNF needs to adjust the grayscale strategy (such as reducing the proportion of grayscale users), or return the results to the upgrade management, manually intervention by the operator (such as reducing the proportion of grayscale users).
