Description
Technical field
A kind of the present invention relates to communications field, more particularly to method and apparatus for rebuilding virtual network function.
Background technology
Among existing network framework, network function and the network equipment are the superpower relations for coupling, network work(
Can be realized by the proprietary equipment of specially design, manufacturer.Inconvenience is this results in, such as：
Raising of these equipment in performance, is limited to meet specific/customization demand and while keep carrier class
The development of the hardware of reliability；And for example, when operator will dispose new business, must dispose in advance and newly set
Equipment meter, that there is related special function, this can improve the service deployment cost of operator.The opposing party
Face, as the performance of CPU and internal memory is rapidly improved, runs net in a software form on universal server
Network function just possesses basic condition, network function virtualization (Network Function Virtualization,
NFV) technology is also arisen at the historic moment, and its target is exactly operational network function on general hardware device, from
And pass through deployment on a large scale, it is possible to decrease CAPEX.Virtualized technology allow network function by
Need ground deployment and update, and greatly facilitate remote management and maintenance, it is possible to decrease OPEX.
After NFV technology is introduced, the management framework of existing network there occurs great changes, referring specifically to Fig. 1.
Fig. 1 be prior art in NFV management and dispatchings (NFV Management and Orchestration,
NFV-MANO) the schematic diagram of framework.Wherein network function virtualization composer (Network Functions
Virtualization Orchestrator, NFVO) be responsible for network service life cycle management, across virtuality
The network function virtualization of architecture management entity (Virtualised Infrastructure Manager, VIM)
Infrastructure (Network Functions Virtualization Infrastructure, NFVI) scheduling of resource
Etc. function, network function virtual management entity (VNF Manager, VNFM) is responsible for VNF examples
Life cycle management, each VNF example assumes that the VNFM for having an association, VIM are responsible for control
System and the calculating of management NFVI, storage and Internet resources.Using comprising net more than conventional telecommunication network webmaster
Network management system (Network Management System, NMS), Element management system (Element
Management System, EMS) and network element three-layer pipe reason structure, wherein NMS and EMS it
Between interface be northbound interface, be southbound interface between EMS and network element.After network function virtualization,
Traditional network management is responsible for the management of virtual network function application layer.
VNF includes multiple virtual network function components (VNF Component, VNFC), VNFC
It is built upon on virtual container, the relation of typical VNFC and virtual container is 1：1 relation.Empty
Intend being assigned virtual resource on container for VNFC uses, wherein virtual resource includes the calculating of virtuality, deposits
Storage and Internet resources.The life cycle of VNF includes instantiation VNF, terminates VNF examples, flexible VNF
(contraction scale in are specifically divided into, scale out are extended, are increased capacity scale up and is reduced capacity scale
Tetra- kinds of down) and repair the processes such as VNF.Reparation generally refers to break down or property in network element or equipment
Network element and equipment can be made to return to the process of normal operation during degradation, broad sense also includes the diagnosis of problem
Process, while the mode that repairs automatically can effectively reduce the cost of operation maintenance.Fig. 2 is prior art
The interaction figure that middle VNF is repaired.As shown in Fig. 2 after determination needs to carry out VNFC reconstructions, first
Business migration is carried out to standby host, is then operated by the contraction VNF (Scale in VNF) of life cycle,
The VNFC that need to be rebuild is discharged, then is grasped by the extension VNF (Scale out VNF) of life cycle
Set up new VNFC to reach the purpose for repairing VNF examples.But if complete in the flow process
Into the operation that entirely repairs, the VNF that stretched on the interface between EM and VNFM twice is needed
Operation, corresponding VNFM needs to carry out authorization requests twice to NFVO, thus extends and repair
The multiple time.
