背景技术Background technique
网络功能虚拟化(Network Function Virtualization，NFV)是电信网络运营商通过借鉴信息技术(Information Technology，IT)领域的虚拟化技术，在通用的云服务器、交换机和存储器中将部分电信网络功能进行软件和硬件解耦，从而实现网络服务(NetworkService，NS)快速、高效部署，同时达到节省投资成本和运营成本的运营目标。Network Function Virtualization (Network Function Virtualization, NFV) is a telecom network operator, by referring to the virtualization technology in the field of Information Technology (IT), to integrate some telecom network functions into software and Hardware decoupling enables rapid and efficient deployment of Network Services (NS), and at the same time achieves the operational goal of saving investment and operating costs.
在NFV的环境下，NS是由一组虚拟化网络功能(Virtualized Network Functions，VNF)和/或一组嵌套的网络服务(Nested NS)组成的呈现网络连接特征的完整功能。NS由其功能和行为特性所确定，在欧洲通信标准化协会(European TelecommunicationsStandards Institute，ETSI)的网络功能虚拟化管理和编排(Network FunctionVirtualization Management and Orchestration，NFV MANO)标准中实现一组生命周期管理(Life Cycle Management，LCM)的功能。目前，NS LCM操作是非实时性的。例如，当按需实例化、弹性伸缩或更新一个NS实例时，耗费的时间通常短到数分钟，长到数十分钟。其中虚拟资源的分配是耗时的主要部分。In the environment of NFV, NS is a complete function that presents the characteristics of network connection composed of a set of virtualized network functions (Virtualized Network Functions, VNF) and/or a set of nested network services (Nested NS). NS is determined by its functional and behavioral characteristics, and implements a set of life cycle management (Lifecycle Management) in the Network Function Virtualization Management and Orchestration (NFV MANO) standard of the European Telecommunications Standards Institute (ETSI). Cycle Management, LCM) functions. Currently, NS LCM operations are not real-time. For example, when on-demand instantiation, auto-scaling, or updating an NS instance, the time spent is usually as short as a few minutes and as long as tens of minutes. The allocation of virtual resources is the main part of time-consuming.
另外，第五代移动通信(5th Generation，5G)切片管理(Slice Management)场景的引入带来了NFV环境下NS LCM管理多样性的新特点，要求NS LCM操作加强实时响应和处理的能力。典型的场景包括：自动驾驶应用、远程医疗、娱乐与游戏等。需要将管理面的NFVMANO操作时延降至秒级甚至更低，以应对NFV技术支持5G切片管理场景中对时延非常敏感的垂直应用的需求。但是现有的NFV MANO功能无法实现这一目标。In addition, the introduction of the fifth generation mobile communication (5th Generation, 5G) slice management (Slice Management) scenario brings new features of NS LCM management diversity in the NFV environment, requiring NS LCM operations to enhance real-time response and processing capabilities. Typical scenarios include: autonomous driving applications, telemedicine, entertainment and games, etc. It is necessary to reduce the delay of NFVMANO operations on the management plane to the second level or even lower to meet the requirements of NFV technology to support vertical applications that are very sensitive to delay in the 5G slice management scenario. But existing NFV MANO capabilities cannot achieve this goal.

本发明提出一种虚拟资源分配方法、装置和系统，根据一类具有超低时延或实时性需求的垂直应用的典型业务特征将NFVI层的虚拟机或容器资源提前组装成不同规格的VNFC、VNF实例和/或嵌套NS实例，当NFVO执行NS LCM操作时，直接从可用的半成品VNFC、VNF实例和/或嵌套NS实例中选择组装或更新待操作的NS实例。The present invention proposes a virtual resource allocation method, device and system. According to the typical business characteristics of a class of vertical applications with ultra-low latency or real-time requirements, virtual machines or container resources at the NFVI layer are assembled in advance into VNFCs of different specifications, VNF instances and/or nested NS instances, when NFVO executes NS LCM operations, directly select and assemble or update NS instances to be operated from available semi-finished VNFCs, VNF instances and/or nested NS instances.
以下举例说明利用5G切片实现的垂直行业应用的典型业务特征如何确定满足超低时延或实时性需求的不同规格的VNFC，VNF实例和/或嵌套NS实例。例如，某体育场举行热门比赛，在观看比赛中观众通过手机视频在朋友圈或推特上分享。在这个过程中要求上传视频不能卡顿，具有较强的实时互动性。业务资源特征分析如下：The following example illustrates how typical business characteristics of vertical industry applications implemented using 5G slicing determine VNFCs of different specifications, VNF instances and/or nested NS instances that meet ultra-low latency or real-time requirements. For example, a popular game is held in a stadium, and the audience uses mobile phone videos to share on Moments or Twitter while watching the game. In this process, it is required that the uploaded video should not be stuck, and it has strong real-time interactivity. The characteristics of business resources are analyzed as follows:
1、比赛前半小时之前，业务流量非常小，主要终端用户为场地工作人员。1. Before half an hour before the game, the business traffic is very small, and the main end users are venue staff.
2、比赛前半小时之内到开场，业务流量逐渐增大，而且主要是下行数据，体现为不断到场的观众以及场馆周边的观众下载刷新比赛相关的新闻、宣传广告或赛前预测等视频。2. From half an hour before the game to the opening, the business traffic gradually increases, and it is mainly downlink data, which is reflected in the download and refresh of news, advertisements or pre-match predictions related to the game by the audience who are constantly present and around the venue.
3、比赛开始后，随着比赛的进行，上行业务流逐渐增大，下行业务流保持不变或减少，体现为观众不断地录得视频上传到网络与朋友分享。3. After the start of the competition, as the competition progresses, the upstream business flow gradually increases, while the downstream business flow remains unchanged or decreases, which is reflected in the fact that the audience continuously records videos and uploads them to the network to share with friends.
4、比赛结束时，上行业务流达到峰值，体现为观众的情绪达到最高，同时录取视频上传网络的数量达到顶峰。4. At the end of the game, the upstream business flow reaches its peak, which is reflected in the highest emotion of the audience, and the number of recorded videos uploaded to the network reaches its peak.
5、比赛结束后半小时，观众逐渐散去。业务流量递减，最后恢复到比赛前的状态。5. Half an hour after the game ended, the audience gradually dispersed. The business flow decreased, and finally returned to the state before the game.
根据上述应用的典型业务流特征，应用的提供商可以提前组装出与不同的业务流模型相匹配的不同虚拟资源规格的VNFC或VNF实例。例如：对于以上例子中需要部署在体育馆的虚拟化分组交换网关(virtualized Packet switching GateWay，vPGW)(其可以理解为一种VNF实例)，可以确定五档不同资源规格：According to the typical service flow characteristics of the above applications, the application provider can assemble VNFC or VNF instances with different virtual resource specifications matching different service flow models in advance. For example: for the virtualized packet switching gateway (virtualized Packet switching GateWay, vPGW) (which can be understood as a VNF instance) that needs to be deployed in the stadium in the above example, five different resource specifications can be determined:
规格1：低资源配置的VNF(低计算资源、低存储资源、低网络资源)。Specification 1: VNF with low resource configuration (low computing resources, low storage resources, low network resources).
规格2：上行网络资源较高配置的VNF(中计算资源、中存储资源、中上行网络资源、低下行网络资源)。Specification 2: VNF with higher configuration of uplink network resources (medium computing resources, medium storage resources, medium uplink network resources, low downlink network resources).
规格3：上行网络资源高配置的VNF(高计算资源、高存储资源、高上行网络资源、中下行网络资源)。Specification 3: VNF with high configuration of uplink network resources (high computing resources, high storage resources, high uplink network resources, medium downlink network resources).
规格4：下行网络资源较高配置的VNF(中计算资源、中存储资源、中下行网络资源、低上行网络资源)。Specification 4: VNF with higher configuration of downlink network resources (medium computing resources, medium storage resources, medium downlink network resources, low uplink network resources).
规格5：下行网络资源高配置的VNF(高计算资源、高存储资源、高下行网络资源、中上行网络资源)。Specification 5: VNF with high configuration of downlink network resources (high computing resources, high storage resources, high downlink network resources, medium uplink network resources).
当NFVO监控到NS所占用虚拟资源的动态变化越过预定的门限后，或者当NFVO接收到OSS/BSS发起的特定NS LCM操作请求后，NFVO直接从包括不同虚拟资源规格的VNF实例和/或嵌套NS实例的资源池中，选择满足NS LCM操作请求中资源需求的一类规格的半成品VNF实例和/或嵌套NS实例，来组装或更新NS实例。When NFVO monitors that the dynamic change of the virtual resources occupied by NS exceeds the predetermined threshold, or when NFVO receives a specific NS LCM operation request initiated by OSS/BSS, NFVO directly selects the VNF instance and/or embedded In the resource pool of the nested NS instance, select a semi-finished VNF instance and/or nested NS instance that meet the resource requirements in the NS LCM operation request to assemble or update the NS instance.

S103、当第一NS实例化请求中的指示信息指示进行实时化处理时，NFVO根据NS实例化限制条件、第一VNF实例化参数从NS实例资源池中选择VNF实例，和/或，NFVO根据NS实例化限制条件、第一嵌套NS实例化参数从NS实例资源池中选择嵌套NS实例，其中，NS实例资源池包括使用不同资源规格的VNF实例和/或嵌套NS实例。S103. When the indication information in the first NS instantiation request indicates to perform real-time processing, NFVO selects a VNF instance from the NS instance resource pool according to the NS instantiation restriction conditions and the first VNF instantiation parameters, and/or, NFVO selects a VNF instance according to The NS instantiation restriction and the first nested NS instantiation parameter select a nested NS instance from the NS instance resource pool, wherein the NS instance resource pool includes VNF instances and/or nested NS instances using different resource specifications.
NS实例化限制条件包括但不限于：VNF实例之间和/或嵌套NS实例之间的位置约束、亲和性、反亲和性规则等限定条件。NS instantiation restrictions include, but are not limited to: location constraints, affinity, and anti-affinity rules between VNF instances and/or nested NS instances.
NS实例资源池可以认为是一个模拟的NS实例，是一个普通的NS实例经过资源裁剪和功能裁剪后形成的一种特殊的NS实例。NS实例资源池包含一组反映不同虚拟资源规格的VNF实例和/或嵌套NS实例，这些VNF实例和/或嵌套NS实例面向具有超低时延和/或实时性强的一类垂直行业应用的业务特征而量身定制的。以上述体育馆观赛的场景为例，服务提供商可以为该类特定的应用创建一个NS实例资源池，NS实例资源池包含5个定制化的VNF实例，每个VNF实例所分配的虚拟资源分别对应规格1到规格5中的一种。鉴于体育馆观赛是一类在固定场所或地点发生的有规律性的业务流量变化特征的应用，该NS实例资源池中的VNF实例所使用的资源可以在同一资源位置(例如，相同的数据中心、资源区和主机)进行分配，或者该NS实例资源池中的VNF实例无需进行亲和性和/或反亲和性规则的限定。对于NS实例资源池而言，它最重要的特征是拥有这些已经分配了虚拟资源的反映不同资源规格的VNF实例和/或嵌套的NS实例，这些VNF实例和/或嵌套的NS实例之间没有通过虚拟链路进行连接，能够被该类垂直应用中的实际NS实例灵活地调用来进行自身实例的组装或更新。The NS instance resource pool can be considered as a simulated NS instance, which is a special NS instance formed after a common NS instance undergoes resource pruning and function pruning. The NS instance resource pool contains a group of VNF instances and/or nested NS instances that reflect different virtual resource specifications. These VNF instances and/or nested NS instances are aimed at a class of vertical industries with ultra-low latency and/or strong real-time performance Tailored to the business characteristics of the application. Taking the above scenario of watching a game in a stadium as an example, the service provider can create an NS instance resource pool for this type of specific application. The NS instance resource pool contains 5 customized VNF instances, and the virtual resources allocated by each VNF instance are respectively Corresponds to one of specifications 1 to 5. In view of the fact that stadium viewing is a type of application with regular service traffic changes occurring in a fixed place or location, the resources used by the VNF instances in the NS instance resource pool can be in the same resource location (for example, the same data center , resource zone and host), or the VNF instance in the NS instance resource pool does not need to be limited by affinity and/or anti-affinity rules. For the NS instance resource pool, its most important feature is to have these VNF instances and/or nested NS instances reflecting different resource specifications that have been allocated virtual resources, and one of these VNF instances and/or nested NS instances They are not connected by virtual links, and can be flexibly called by actual NS instances in this type of vertical application to assemble or update their own instances.
第一VNF实例化参数或第一嵌套NS实例化参数并非用于显式地指示对应的VNF实例资源规格或嵌套NS实例资源规格，而是NFVO需要根据第一VNF实例化参数和NS实例化限制条件来选择NS实例资源池中的一种VNF实例资源规格，以满足第一VNF实例化参数中所描述的对VNF实例化的要求，例如：实例化容量的大小。与之类似的，NFVO需要根据第一嵌套NS实例化参数和NS实例化限制条件来选择NS实例资源池中的一种嵌套NS实例资源规格，以满足第一嵌套NS实例化参数中所描述的对嵌套NS实例化的要求。The first VNF instantiation parameter or the first nested NS instantiation parameter is not used to explicitly indicate the corresponding VNF instance resource specification or nested NS instance resource specification, but NFVO needs to use the first VNF instantiation parameter and NS instance A VNF instance resource specification in the NS instance resource pool is selected according to the constraints of the instantiation, so as to meet the requirements for VNF instantiation described in the first VNF instantiation parameter, for example, the size of the instantiation capacity. Similarly, NFVO needs to select a nested NS instance resource specification in the NS instance resource pool according to the first nested NS instantiation parameters and NS instantiation constraints, so as to satisfy the first nested NS instantiation parameters Described requirements for nested NS instantiations.
需要说明的是，如果指示信息指明该NS实例化操作不需要进行实时化处理，则NFVO按照常规的NS实例化过程进行。It should be noted that, if the indication information indicates that the NS instantiation operation does not need to be processed in real time, the NFVO is performed according to a conventional NS instantiation process.
S104、NFVO对所选择的VNF实例和/或嵌套NS实例进行组装和/或配置以实例化第一NS实例。S104. The NFVO assembles and/or configures the selected VNF instance and/or nested NS instance to instantiate the first NS instance.
本申请实施例提供的虚拟资源分配方法，当有实时化需求时，根据NS实例化限制条件和实例化参数从NS实例资源池中选择满足要求的VNF实例和/或嵌套NS实例，进行组装和/或配置以实例化NS实例。由于NS实例资源池中的VNF实例和/或嵌套NS实例事先分配了虚拟资源，不需要在NS LCM操作中再次分配虚拟资源，节省了操作响应时间，从而降低NSLCM操作的时延。The virtual resource allocation method provided by the embodiment of the present application, when there is a real-time requirement, selects a VNF instance and/or nested NS instance that meet the requirements from the NS instance resource pool according to the NS instantiation constraints and instantiation parameters, and assembles them and/or configure to instantiate an NS instance. Since the VNF instances and/or nested NS instances in the NS instance resource pool have allocated virtual resources in advance, there is no need to allocate virtual resources again in the NS LCM operation, which saves the operation response time and reduces the delay of the NSLCM operation.
