Abstract

Disclosed are a method and device for re-instantiating a virtual network function. The method comprises: a virtual network function manager (VNFM) receives information indicating that a re-instantiation of a virtual network function (VNF) instance is required; the VNFM requests a virtualized infrastructure manager (VIM) to release the virtual resource corresponding to the VNF instance required to be re-instantiated and to allocate a virtual resource required for instantiating a new VNF instance; after completion of the release of the virtual resource corresponding to the VNF instance required to be re-instantiated, the VNFM uses the virtual resource allocated by the VIM to establish a new VNF instance, wherein the new VNF instance has a deployment parameter consistent with a deployment parameter of the VNF instance required to be re-instantiated, and has identification information the same as said VNF instance.

重新实例化虚拟网络功能的方法和装置Method and apparatus for re-instantiating virtual network functions

技术领域Technical field

本申请涉及但不限于通信领域。This application relates to, but is not limited to, the field of communications.

背景技术Background technique

在相关技术的网络架构之中，网络功能与网络设备是超强耦合的关系，网络功能均通过专门设计的、厂商专有的设备来实现。这带来了诸多不便，比如：这些设备在性能上的提高，受限于满足特定/定制化需求而且同时保持电信级可靠性的硬件的发展；又如，当运营商要部署新的业务时，须事先部署新设计的、具有相关专用功能的设备，这会提高运营商的业务部署成本。另一方面，随着CPU及内存的性能快速地提高，通用型服务器上以软件形式运行网络功能就具备了基础条件，网络功能虚拟化(Network Function Virtualization，NFV)技术也应运而生，它目标就是在通用的硬件设备上运行网络功能，从而通过大范围的部署，可降低资本支出(capital expenditures,CAPEX)。虚拟化的技术使得网络功能可以按需地部署及更新，且极大地方便远程管理及维护，可降低运营支出(Operating expenditures，OPEX)。In the network architecture of the related art, the network function and the network device are super-coupled, and the network functions are realized by specially designed, vendor-specific devices. This brings a lot of inconveniences, such as: the performance improvement of these devices is limited by the development of hardware that meets specific/customized requirements while maintaining carrier-class reliability; for example, when operators deploy new services. Newly designed devices with associated special functions must be deployed in advance, which will increase the operator's business deployment costs. On the other hand, with the rapid improvement of the performance of the CPU and memory, the general-purpose server has the basic conditions for running the network function in software form, and Network Function Virtualization (NFV) technology has emerged as the times require. It is the operation of network functions on general-purpose hardware devices, which can reduce capital expenditures (CAPEX) through a wide range of deployments. Virtualized technology enables network functions to be deployed and updated on demand, and greatly facilitates remote management and maintenance, reducing operational expenditures (OPEX).

NFV引入后相关技术的网络的管理架构发生了很大变化，如图1所示，NFV管理调度(NFV Management and Orchestration，NFV-MANO)的架构图及参考点。其中网络功能虚拟化编排器(Network Functions Virtualization Orchestrator，NFVO)负责网络服务的生命周期管理、跨虚拟架构管理实体(Virtualised Infrastructure Manager，VIM)的网络功能虚拟化基础设施(Network Functions Virtualization Infrastructure，NFVI)资源调度等功能，网络功能虚拟化管理实体(VNF Manager，VNFM)负责VNF实例的生命周期管理，每个VNF实例假设都有一个关联的VNFM，VIM负责控制和管理NFVI的计算，存储和网络资源。传统电信网络网管多采用包含网络管理***(Network Management System，NMS)/运营支撑***(Operating Support System，OSS)、网元管理***(Element Management System，EMS)和网元的三层管理结构，其中NMS和EMS之间的接口是北向接口，EMS和网元之间是南向接口。在网络功能虚拟化后，传统网管负责虚拟网络功能应用层的管理。The management architecture of the network after the introduction of NFV has undergone great changes. As shown in Figure 1, the architecture diagram and reference point of NFV Management and Orchestration (NFV-MANO). The Network Functions Virtualization Orchestrator (NFVO) is responsible for the lifecycle management of network services and the Network Functions Virtualization Infrastructure (NFVI) of Virtualised Infrastructure Manager (VIM). For resource scheduling and other functions, the Network Function Virtualization Management Entity (VNFM) is responsible for the lifecycle management of VNF instances. Each VNF instance assumes an associated VNFM. VIM is responsible for controlling and managing NFVI calculations, storage and network resources. . The traditional telecommunication network management system adopts a three-layer management structure including a network management system (NMS)/Operation Support System (OSS), an element management system (EMS), and a network element. The interface between the NMS and the EMS is the northbound interface, the EMS and the network element. The middle is the southbound interface. After the network function is virtualized, the traditional network management is responsible for the management of the virtual network function application layer.

网络服务(Network Service，NS)将由一系列相互连接的VNF和或物理网络功能(Physical Network Function，PNF)实现，VNF/PNF相互连接构成虚拟链路(Virtual Link，VL)，整个网络服务的VNF转发的路径(VNF Forwarding Graphs，VNFFG)由虚拟链路和VNF/PNF连接点(Connection Point，CP)构成。网络服务的生命周期包括实例化(Instantiate)NS、终止(Terminate)NS、伸缩(Scale)NS、更新(Update)NS及创建/删除/查询/更新VNFFG或VL等，VNF的生命周期包括实例化VNF、终止VNF实例、伸缩VNF及修复VNF等过程，其中Scale分为收缩(scale in)、扩展(scale out)、增加容量(scale up)和减少容量(scale down)四种。修复一般是指在网元或设备出现故障或性能严重下降时使网元和设备恢复到正常运行的过程，广义还包括问题的诊断过程，网元或设备发生故障时网络服务很有可能就会受到影响，导致服务质量下降。The Network Service (NS) will be implemented by a series of interconnected VNFs or physical network functions (PNFs). The VNF/PNFs are interconnected to form a virtual link (Virtual Link, VL), and the entire network service VNF. The VNF Forwarding Graphs (VNFFG) consist of a virtual link and a VNF/PNF Connection Point (CP). The life cycle of a network service includes instantiating NS, terminating NS, scaling NS, updating NS, and creating/deleting/query/updating VNFFG or VL, etc., and the life cycle of the VNF includes instantiation. VNF, termination of VNF instances, scaling VNF, and repairing VNF, among which Scale is divided into four types: scale in, scale out, scale up, and scale down. Repairing generally refers to the process of restoring network elements and devices to normal operation when a network element or device fails or performance is severely degraded. It also includes the diagnosis process of the problem in general. When the network element or device fails, the network service is likely to be Affected, resulting in a decline in service quality.

相关技术的网络服务修复的流程如图2所示，当确定需要修复网络服务且方式为重新实例化VNF实例后，首先将业务迁移到容灾的VNF，然后OSS需要先通过Scale in NS使NFVO请求VNFM终止需要重新实例化的VNF实例，再通过Scale out NS使NFVO请求VNFM实例化新的VNF，来达到修复网络服务的目的。The network service repair process of the related art is as shown in FIG. 2. When it is determined that the network service needs to be repaired and the VNF instance is re-instantiated, the service is first migrated to the disaster-tolerant VNF, and then the OSS needs to first make the NFVO through the Scale in NS. The VNFM is requested to terminate the VNF instance that needs to be re-instantiated, and then the NFVO request VNFM to instantiate the new VNF through Scale out NS to achieve the purpose of repairing the network service.

发明内容Summary of the invention

以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。The following is an overview of the topics detailed in this document. This Summary is not intended to limit the scope of the claims.

在相关技术的网络服务修复的流程中，如果要完成整个修复的操作，需要在OSS和NFVO之间的接口上进行两次伸缩NS的操作，对应的NFVO和VNFM需要进行两次生命周期的操作请求以及其授权的过程。同时因为VNFM在实例化新的VNF时并不知道新VNF是用来替代已故障的VNF，所以新VNF的部署参数和已故障的VNF是不相同的，那么如果要将新的VNF接入到网络服务中替换需修复的VNF，OSS需要更新与该需修复的VNF相关的VNFFG和VL，此外，在每次生命周期完成后VNFM会通知EM，EM会对VNF实例对应的管理对象进行操作，对应VNFM进行的终止和实例化操作，EM需要进行管理对象的删除和创建，这样使得整个修复的过程非常复杂，也消耗了更多的时间。In the related network service repair process, if the entire repair operation is to be completed, the NS operation needs to be performed twice on the interface between the OSS and the NFVO, and the corresponding NFVO and VNFM need to perform two life cycle operations. The process of requesting and its authorization. At the same time, because VNFM does not know that the new VNF is used to replace the failed VNF when instantiating the new VNF, the deployment parameters of the new VNF are different from the failed VNF, then if the new VNF is to be connected to Replace the VNF to be repaired in the network service. The OSS needs to be updated with the VNF to be repaired. The VNFFG and VL are closed. In addition, the VNFM notifies the EM after each life cycle is completed. The EM operates on the management object corresponding to the VNF instance, and the EM needs to delete the management object corresponding to the termination and instantiation of the VNFM. Create, which makes the entire repair process very complicated and consumes more time.
