技术领域Technical field

本发明涉及网络功能虚拟化技术领域，尤其涉及一种虚拟网络业务部署方法和设备。The present invention relates to the field of network function virtualization technologies, and in particular, to a virtual network service deployment method and device.

背景技术Background technique

随着互联网技术的发展，网络运营商部署的网络是由多种多样的物理设备组成。不同的网络业务需要不同的物理设备，每开发一个新的网络业务，相应需要增加新类型的物理设备，但是确定新增物理设备的空间位置以及供电线路随着网络业务的增加变得越来越困难，这样就严重抑制了新网络业务的部署。With the development of Internet technology, the network deployed by network operators is composed of a variety of physical devices. Different network services require different physical devices. Each time a new network service is developed, a new type of physical device needs to be added, but the spatial location of the newly added physical device and the power supply line become more and more as the network service increases. Difficulties, this severely inhibited the deployment of new network services.

为了解决上述存在的问题，提出了网络功能虚拟化(NFV，Network Functions Virtualization)，其中，网络功能虚拟化是指在通用物理设备上运行网络功能，常见的形式为：在物理设备上部署虚拟机。In order to solve the above problems, Network Function Virtualization (NFV) is proposed. Among them, network function virtualization refers to running network functions on general physical devices. The common form is: deploying virtual machines on physical devices. .

目前提出的NFV架构包含了业务运营和管理平台(OSS/BSS，Operation-Support System/Business Support System)，服务、虚拟化的网络功能和基础设备描述单元(Service，VNF(Virtual Network Function)and Infrastructure Description)、网络功能虚拟化管理和编排平台(NFV Management and Orchestration)。The current NFV architecture includes the Operational and Support System/Business Support System (OSS/BSS), the service, the virtualized network function, and the basic device description unit (Service, VNF (Virtual Network Function) and Infrastructure. Description), Network Function Virtualization Management and Orchestration (NFV Management and Orchestration).

具体地，OSS/BSS除了传统管理功能之外，针对虚拟化应用与Orchestrator交互完成对网络的操作和维护。Specifically, in addition to the traditional management functions, the OSS/BSS interacts with the Orchestrator for the operation and maintenance of the network for the virtualized application.

服务、虚拟化的网络功能和基础设备描述单元包含了NS信息模型描述模板(NSD，NS Descriptor)、VNF信息模型描述模板(VNFD，VNF Descriptor)、虚拟链路描述模板(VLD，Virtual Link Descriptor)、VNF软件镜像等。The service, virtualized network function and basic device description unit include an NS information model description template (NSD, NS Descriptor), a VNF information model description template (VNFD, VNF Descriptor), Virtual link description template (VLD, Virtual Link Descriptor), VNF software image, and so on.

其中，NSD由运营商或者集成商规划网络信息，该网络信息包含使用VNFD列表、支持的网络业务(NS，Network Service)容量以及不同NS容量对应的VNF实例列表以及VLD列表等。The NSD is planned by the operator or the integrator, and the network information includes a VNFD list, a supported network service (NS, Network Service) capacity, and a VNF instance list and a VLD list corresponding to different NS capacities.

VNFD由虚拟化的网络功能(VNF，Virtual Network Function)提供商提供，包含了VNF功能、VNF支持的容量列表、不同容量情况下需要的虚拟机列表、各虚拟机的部署软件信息以及外出端口等。The VNFD is provided by a Virtual Network Function (VNF) provider, which includes VNF functions, a list of capacities supported by the VNF, a list of virtual machines required for different capacity, deployment software information of each virtual machine, and outgoing ports. .

VLD用于描述VNF实例链路需求，链路的两端由VNF实例类型的连接点(CP，Connect Point)(例如：VNF_CP标识)表示。The VLD is used to describe the link requirements of the VNF instance. The two ends of the link are represented by the connection point (CP, Connect Point) of the VNF instance type (for example, VNF_CP identifier).

Orchestrator(编排平台)是对至少一个数据中心的NS生命周期管理(例如：部署/扩容/下线等)、NFVI资源编排，主要是利用NSD完成对NS的网络规划，分解出各VNF的需求，并将VNFD以及VNF的容量需求下发给VNF管理***(VNFM，NFV Manager)，再由VNFM完成VNF的部署。Orchestrator (Organization Platform) is the NS lifecycle management (for example: deployment/expansion/downline, etc.) and NFVI resource orchestration for at least one data center. It mainly uses NSD to complete network planning for NS and decomposes the requirements of each VNF. The VNFD and VNF capacity requirements are sent to the VNF management system (VNFM, NFV Manager), and the VNFM is deployed by the VNFM.

具体地，Orchestrator在接收到OSS发送的NS实例化请求时，根据NS实例化请求中携带的NSD索引，获取NSD索引对应的NSD，并从获取的NSD中得到需要实例化的VNF实例列表；再根据得到的VNF实例列表中的VNF实例，选择满足该VNF实例的VNFD索引，并利用VNFD索引对应的VNFD进行实例化操作。Specifically, when receiving the NS instantiation request sent by the OSS, the Orchestrator obtains the NSD corresponding to the NSD index according to the NSD index carried in the NS instantiation request, and obtains a list of VNF instances that need to be instantiated from the obtained NSD; According to the VNF instance in the obtained VNF instance list, the VNFD index that satisfies the VNF instance is selected, and the VNFD corresponding to the VNFD index is used for instantiation operation.

其中，在NSD中，部署在同一个NS的不同VNF实例的容量与NS容量是相同的。The capacity of the different VNF instances deployed in the same NS is the same as the NS capacity in the NSD.

由此可见，在Orchestrator对VNF实例化进行部署时，Orchestrator按照NS总容量，部署每一个VNF实例的容量(即部署每一个VNF实例的容量与NS总容量相同)，存在资源浪费的问题。Therefore, when the Orchestrator deploys the VNF instantiation, the Orchestrator deploys the capacity of each VNF instance according to the total NS capacity (that is, the capacity of each VNF instance is the same as the total NS capacity), and there is a problem of waste of resources.

发明内容Summary of the invention

Effectively save virtual resources.

实施例二：Embodiment 2:

如图2所示，为本发明实施例二提供的一种虚拟网络业务部署方法的流程示意图。所述方法可以如下所述。FIG. 2 is a schematic flowchart diagram of a virtual network service deployment method according to Embodiment 2 of the present invention. The method can be as follows.

步骤201：Orchestrator根据接收到的网络业务NS实例化请求中携带的NS信息模型描述模板NSD索引，获取所述NSD索引对应的NSD信息。Step 201: The Orchestrator obtains the NSD index corresponding to the NSD index according to the NS information model description template NSD index carried in the received NS instantiation request.

The scale parameter of the VNF instance corresponding to the type.

在步骤201中，运营商向设备商购买VNF时，设备提供商需要提供相应的Orchestrator能够正确解读的VNFD模板以及VNF软件包，运营商通过OSS或者Orchestrator开放的接口将VNFD模板以及VNF软件包注册到Catalog中，并得到每一个VNFD模板对应的VNFD索引。In step 201, when the operator purchases the VNF from the equipment vendor, the equipment provider needs to provide the VNFD template and the VNF software package that the Orchestrator can correctly interpret, and the operator registers the VNFD template and the VNF software package through the open interface of the OSS or the Orchestrator. Go to the Catalog and get the VNFD index for each VNFD template.

当运营商规划网络时，由***集成商或者运营商按照业务需要完成网络规划，并按照Orchestrator支持的格式完成NSD模板以及VLD模板的构建，并将构建的NSD模板以及VLD模板通过OSS或者Orchestrator开放的接口注册到Catalog中，并得到每一个NSD模板对应的NSD索引，以及每一个VLD模板对应的VLD索引。When the operator plans the network, the system integrator or the operator completes the network planning according to the business needs, and completes the NSD template and VLD template construction according to the format supported by the Orchestrator, and opens the constructed NSD template and VLD template through OSS or Orchestrator. The interface is registered in the Catalog, and the NSD index corresponding to each NSD template and the VLD index corresponding to each VLD template are obtained.

具体地，在需要进行虚拟网络部署时，需要对NS进行实例化，具体方式包括但不限于：Specifically, when the virtual network needs to be deployed, the NS needs to be instantiated, including but not limited to:

第一步，OSS向Orchestrator发起NS实例化请求。In the first step, the OSS initiates an NS instantiation request to the Orchestrator.

其中，实例化请求中携带了NS的容量以及NSD(NS信息模型描述模板，NS Descriptor)索引。 The instantiation request carries the capacity of the NS and the NSD (NS Descriptor, NS Descriptor) index.

第二步，Orchestrator根据NS实例化请求中携带的NSD索引，从Catalog中获取该NSD索引对应的NSD模板。In the second step, the Orchestrator obtains the NSD template corresponding to the NSD index from the catalog according to the NSD index carried in the NS instantiation request.

其中，NSD模板中包含了至少一个NS部署参数。The NSD template includes at least one NS deployment parameter.

其中，每一个VNF实例类型对应的VNFD信息可以是VNFD索引，还可以是Vendor(运营商)标识和VNFD索引，这里不做限定。The VNFD information corresponding to each VNF instance type may be a VNFD index, or may be a Vendor (operator) identifier and a VNFD index, which are not limited herein.

同一个VNF实例类型对应至少一个VNF实例，不同VNF实例对应的VNFD信息可以相同，也可以不同。The same VNF instance type corresponds to at least one VNF instance. The VNFD information corresponding to different VNF instances may be the same or different.

其中，不同VNF实例对应的VNFD信息不同至少包含：Vendor标识不同、VNFD索引不同中的一种或者多种。The VNFD information corresponding to different VNF instances includes at least one or more of different Vendor identifiers and different VNFD indexes.

其中，Vendor标识不同是指运营商标识不同。The difference between the Vendor logos means that the carrier identifiers are different.

由此可见，本发明实施例的方案可以实现相同VNF实例类型对应的不同VNF实例采用不同Vendor的产品，保证了各个运营商产品的兼容性。It can be seen that the solution of the embodiment of the present invention can implement different Vendor products of different VNF instances corresponding to the same VNF instance type, and ensure the compatibility of each carrier product.

例如：如表1所示的一个NSD模板中包含的至少两个NS部署参数(其中，VNF实例类型对应的VNFD信息包含VNFD索引)：For example, at least two NS deployment parameters included in an NSD template as shown in Table 1 (where the VNFD information corresponding to the VNF instance type includes a VNFD index):

表1Table 1

从表1中可以看出，一旦确定采用哪个NS部署参数，即可确定VNF实例类型、以及VNF实例类型对应的VNFD索引以及VNF实例的比例参数。As can be seen from Table 1, once the NS deployment parameters are determined, the VNF instance type and the VNFD index corresponding to the VNF instance type and the scale parameter of the VNF instance can be determined.

其中，同一个VNF实例类型对应的VNF实例可以是一个，还可以是多个；当同一个VNF实例类型对应的VNF实例为多个VNF实例时，对于同一个VNF实例类型对应的多个VNF实例，不同VNF实例对应的VNFD索引可以相同，也可以不同；当同一个VNF实例类型对应的多个VNF实例，且不同VNF实例对应的VNFD索引相同时，可以通过实例编号区分相同VNFD索引对应的VNF实例，例如：2*VNF C实例对应两个VNF实例，该两个VNF实例对应的VNDF索引为VNFD 4，此时对于2*VNF C实例对应两个VNF实例可以通过No_4和No_5区分。The VNF instance corresponding to the same VNF instance type may be one or more. When the VNF instance corresponding to the same VNF instance type is multiple VNF instances, multiple VNF instances corresponding to the same VNF instance type are used. The VNFD index corresponding to the different VNF instances may be the same or different. When multiple VNF instances corresponding to the same VNF instance type and the VNFD indexes corresponding to different VNF instances are the same, the VNF corresponding to the same VNFD index may be distinguished by the instance number. For example, the 2*VNF C instance corresponds to two VNF instances, and the VNDF index corresponding to the two VNF instances is VNFD 4. In this case, the two VNF instances corresponding to the 2*VNF C instance can be distinguished by No_4 and No_5.

如表2所示的一个NSD模板中包含的至少两个NS部署参数(其中，VNF实例类型对应的VNFD信息包含Vendor标识和NSD中公共Common信息中的VNFD索引)：At least two NS deployment parameters included in an NSD template as shown in Table 2 (wherein the VNFD information corresponding to the VNF instance type includes the Vendor identifier and the VNFD index in the common Common information in the NSD):

表2Table 2

从表2中可以看出，一旦确定采用哪个NS部署参数，即可确定VNF实例类型、以及VNF实例类型对应的Vendor标识以及VNF实例的比例参数。As can be seen from Table 2, once the NS deployment parameter is determined, the VNF instance type, and the Vendor identifier corresponding to the VNF instance type and the scale parameter of the VNF instance can be determined.

其中，同一个VNF实例类型对应的VNF实例可以是一个，还可以是多个；当同一个VNF实例类型对应的VNF实例为多个VNF实例时，对于同一个VNF实例类型对应的多个VNF实例，不同VNF实例对应的Vendor标识可以相同，也可以不同；当同一个VNF实例类型对应的多个VNF实例，且不同VNF实例对应的Vendor标识相同时，可以通过实例编号区分相同VNFD索引对应的VNF实例，例如：2*VNF C实例对应两个VNF实例，每一个VNF实例对应的Vendor标识为Vendor D，此时对于2*VNF C实例对应两个VNF实例可以通过No_4和No_5区分。The VNF instance corresponding to the same VNF instance type may be one or more. When the VNF instance corresponding to the same VNF instance type is multiple VNF instances, multiple VNF instances corresponding to the same VNF instance type are used. The Vendor identifiers of different VNF instances may be the same or different. When multiple VNF instances of the same VNF instance type are used, and the Vendor identifiers of different VNF instances are the same, the VNFs corresponding to the same VNFD index can be distinguished by instance numbers. For example, the 2*VNF C instance corresponds to two VNF instances, and the Vendor identifier corresponding to each VNF instance is Vendor D. In this case, two VNF instances corresponding to the 2*VNF C instance can be distinguished by No_4 and No_5.

步骤202：Orchestrator从获取的所述NSD信息中，确定能够满足接收到的NS实例化请求中携带的待实例化的NS的容量需求的VNF实例。Step 202: The Orchestrator determines, from the obtained NSD information, a VNF instance that can satisfy the capacity requirement of the NS to be instantiated carried in the received NS instantiation request.

在步骤202中，假设接收到的NS实例化请求中携带的待实例化的NS的容量为500Kcaps，那么从步骤101中获取的所述NSD信息中查找与待实例化的NS的容量500Kcaps相同的NS部署参数，即NS部署参数1。In step 202, it is assumed that the capacity of the NS to be instantiated in the received NS instantiation request is 500 Kcaps, and the NSD information obtained in step 101 is the same as the capacity of the NS to be instantiated 500Kcaps. NS deployment parameter, that is, NS deployment parameter 1.

由此可见，NS部署参数1中至少需要建立的实例化包含了1*VNF A实例、2*VNF B实例和2*VNF C实例。It can be seen that at least the instantiation that needs to be established in the NS deployment parameter 1 includes a 1*VNF A instance, a 2*VNF B instance, and a 2*VNF C instance.

具体地，从获取的所述NSD信息中，查找满足接收到的NS实例化请求中携带的待实例化的NS的容量需求的NS部署参数。Specifically, the NS deployment parameter that meets the capacity requirement of the NS to be instantiated carried in the received NS instantiation request is searched for from the obtained NSD information.

具体地，所述网络业务NS实例化请求中携带已进行实例化的VNF实例类型对应的VNF实例的标识，确定尚未进行实例化的VNF实例，包括：Specifically, the network service NS instantiation request carries the VNF instance class that has been instantiated The identifier of the VNF instance corresponding to the type, and the VNF instance that has not been instantiated is determined, including:

将查找到的NS部署参数中包含的每一个VNF实例类型与所述网络业务NS实例化请求中携带已进行实例化的VNF实例类型进行比较。Each VNF instance type included in the found NS deployment parameter is compared with the VNF instance type that is instantiated in the network service NS instantiation request.

也就是说部署参数1中包含的需要建立的实例化中存在已经实例化的VNF实例，那么在本发明实施例中可以不再进行实例化。That is to say, in the instantiation that needs to be established in the deployment parameter 1, there is a VNF instance that has been instantiated, so that it can be no longer instantiated in the embodiment of the present invention.

步骤203：Orchestrator根据确定的VNF实例的比例参数以及所述待实例化的NS的容量，计算所述确定的VNF实例的容量。Step 203: The Orchestrator calculates the capacity of the determined VNF instance according to the determined proportional parameter of the VNF instance and the capacity of the NS to be instantiated.

在步骤203中，假设计算1*VNF A实例对应的NO_1的VNF实例的容量，那么从步骤202得到的NSD模板中查找到VNF部署参数1中1*VNF A实例对应的NO_1的VNF实例的比例参数为100％，再根据待实例化的NS的容量500Kcaps，计算得到1*VNF A实例对应的NO_1的VNF实例的容量为500Kcaps。In step 203, assuming that the capacity of the VNF instance of NO_1 corresponding to the 1*VNF A instance is calculated, the proportion of the VNF instance corresponding to the NO_1 corresponding to the 1*VNF A instance in the VNF deployment parameter 1 is found in the NSD template obtained in step 202. The parameter is 100%, and according to the capacity of the NS to be instantiated, 500Kcaps, the capacity of the VNF instance of NO_1 corresponding to the 1*VNF A instance is calculated to be 500Kcaps.

假设计算2*VNF B实例对应的NO_2的VNF实例的容量，那么从步骤202 得到的NSD模板中查找到VNF部署参数1中2*VNF B实例对应的NO_2的VNF实例的比例参数为50％，再根据待实例化的NS的容量500Kcaps，计算得到2*VNF A实例对应的NO_2的VNF实例的容量为250Kcaps。Assuming that the capacity of the VNF instance of NO_2 corresponding to the 2*VNF B instance is calculated, then from step 202 In the obtained NSD template, the ratio of the VNF instance of the NO 2 corresponding to the 2*VNF B instance in the VNF deployment parameter 1 is 50%, and then the 2*VNF A instance corresponding to the NS capacity to be instantiated is calculated. The capacity of the VNF instance of NO_2 is 250Kcaps.

由此可见，计算得到的所述每一个VNF实例类型对应的VNF实例的容量与NS容量可以相同，也可以不同，与目前将NS容量作为VNF实例的容量相比，节省了***资源。It can be seen that the calculated capacity of the VNF instance corresponding to each VNF instance type may be the same as or different from the NS capacity, and the system resources are saved compared with the current capacity of the NS capacity as the VNF instance.

步骤204：Orchestrator根据所述确定的VNF实例的容量以及所述确定的VNF实例对应的VNFD信息，得到确定的VNF实例需要的资源。Step 204: The Orchestrator obtains the resources required by the determined VNF instance according to the determined capacity of the VNF instance and the VNFD information corresponding to the determined VNF instance.

所述NSD信息中还包含了公共Common信息，其中，所述Common信息中包含了VNFD索引。The NSD information further includes public Common information, where the Common information includes a VNFD index.

当所述每一个VNF实例类型对应的VNFD信息包含Vendor标识时，根据所述确定的VNF实例对应的Vendor标识和所述确定的VNF实例对应的VNF实例类型，从获取的所述NSD信息中，选择Common信息中满足所述确定的VNF实例对应的Vendor标识和所述确定的VNF实例对应的VNF实例类型的VNFD索引；根据所述选择的VNFD索引，获取所述VNFD索引对应的VNFD；针对所述VNFD，根据所述确定的VNF实例的容量，得到确定的VNF实例对应的VDU列表；并利用所述VDU列表，得到每一个VDU对应的虚拟资源、软件资源和端口。When the VNFD information corresponding to each VNF instance type includes a Vendor identifier, according to the Vendor identifier corresponding to the determined VNF instance and the VNF instance type corresponding to the determined VNF instance, from the obtained NSD information, And selecting, in the common information, a VNFD index that meets the Vendor identifier corresponding to the determined VNF instance and the VNF instance type corresponding to the determined VNF instance; and acquiring, according to the selected VNFD index, a VNFD corresponding to the VNFD index; The VNFD is configured to obtain a VDU list corresponding to the determined VNF instance according to the determined capacity of the VNF instance, and obtain the virtual resource, the software resource, and the port corresponding to each VDU by using the VDU list.

例如：如表2所示，1*VNF A实例对应的NO_1的Vendor标识为Vendor A；2*VNF B实例对应的NO_2的Vendor标识为Vendor B；2*VNF B实例对应的NO_3的Vendor标识为Vendor C；等等。For example, as shown in Table 2, the Vendor identifier of NO_1 corresponding to the 1*VNF A instance is Vendor A; the Vendor identifier of NO_2 corresponding to the 2*VNF B instance is Vendor B; the Vendor identifier of NO_3 corresponding to the 2*VNF B instance is Vendor C; and so on.
