Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for reconstructing a virtual network function.
Background
In the existing network architecture, the network function and the network device are in a super-strong coupling relationship, and the network function is realized through specially designed and vendor-specific devices. This brings about a number of inconveniences, such as: the increase in performance of these devices is limited by the development of hardware that meets specific/customized requirements while maintaining carrier-grade reliability; for another example, when an operator wants to deploy a new service, newly designed equipment with related dedicated functions must be deployed in advance, which may increase the service deployment cost of the operator. On the other hand, as the performance of the CPU and the memory is rapidly improved, a basic condition is provided for operating a Network Function in a software form on the general-purpose server, and a Network Function Virtualization (NFV) technology is also developed, which aims to operate the Network Function on general-purpose hardware equipment, so that CAPEX can be reduced by deploying in a large range. The virtualization technology enables network functions to be deployed and updated as required, greatly facilitates remote management and maintenance, and can reduce OPEX.
The management architecture of the existing network has changed greatly after the introduction of NFV technology, see in particular fig. 1. FIG. 1 is a diagram of a prior art NFV Management scheduling (NFV-MANO) architecture. The Network Function Virtualization Orchestrator (NFVO) is responsible for lifecycle management of Network services, Functions such as cross-virtual Infrastructure (NFVI) resource scheduling of a virtual framework management entity (VIM), and the Network function Virtualization management entity (VNF Manager, VNFM) is responsible for lifecycle management of VNF instances, each VNF instance assumes an associated VNFM, and the VIM is responsible for controlling and managing computation, storage, and Network resources of the NFVI. The traditional telecommunication Network Management usually adopts a three-layer Management structure including a Network Management System (NMS), an Element Management System (EMS), and Network elements, wherein an interface between the NMS and the EMS is a northbound interface, and an interface between the EMS and the Network elements is a southbound interface. After the network function is virtualized, the traditional network manager is responsible for managing the virtual network function application layer.
The VNF includes a plurality of Virtual Network Function Components (VNFCs), and the VNFCs are all established on virtual containers, and a typical relationship between the VNFCs and the virtual containers is 1: 1. Virtual resources are allocated on the virtual container for use by the VNFC, wherein the virtual resources include virtual computing, storage, and network resources. The lifecycle of the VNF includes processes of instantiating the VNF, terminating an instance of the VNF, scaling the VNF (specifically, scaling in, scaling out, increasing the capacity scale up, and decreasing the capacity scale down), and repairing the VNF. The repair generally refers to a process of restoring the network element and the equipment to normal operation when the network element or the equipment has a fault or seriously degraded performance, and also includes a diagnosis process of a problem in a broad sense, and meanwhile, the automatic repair mode can effectively reduce the cost of operation and maintenance. Fig. 2 is an interaction diagram of VNF repair in the prior art. As shown in fig. 2, after it is determined that VNFC reconfiguration is required, first, service migration is performed to a standby machine, then, VNFCs to be reconfigured are released through a lifecycle contraction VNF (scale in VNF) operation, and then, a new VNFC is established through a lifecycle expansion VNF (scale out VNF) operation, so as to achieve the purpose of repairing a VNF instance. However, in this process, if the entire repair operation is to be completed, the VNF needs to be scaled twice on the interface between the EM and the VNFM, and the corresponding VNFM needs to make two authorization requests to the NFVO, which prolongs the repair time.
