Description
Technical field
The present invention relates to network function to virtualize field, more particularly to a kind of method and dress for managing network function node
Put.
Background technology
Among existing network framework, network function is the superpower relation coupled with the network equipment, and network function passes through
Equipment specially design, that manufacturer is proprietary is realized.This results in inconvenience：Such as raising of these equipment in performance,
It is limited to the development for meeting the needs of specific/customization and the hardware for keeping carrier level reliability simultaneously；And for example, operator is worked as
When disposing new business, equipment newly-designed, that there is related special function must be disposed in advance, this can improve the industry of operator
Business lower deployment cost.On the other hand, as the performance of CPU and internal memory rapidly improves, transported in a software form on universal server
Row network function just possesses basic condition, network function virtualization (NFV, Network Function
Virtualization) technology is also arisen at the historic moment, and its target is exactly the operational network function on general hardware device, so as to
By disposing on a large scale, Capital expenditure (CAPEX, Capital Expenditure) can be reduced." virtualization " causes network work(
Desirably can dispose and update, and greatly facilitate remote management and maintenance, can reduce management expenditure (OPEX,
Operating Expense)。
In the environment of virtualization, existing network function will be in virtual network function (VNF, Virtual Network
Function realized on), be considered as VNF application layer.Each VNF can realize different nets according to specific application configuration
Network function.The virtualization of network function causes the management framework of existing network also there occurs great changes, as shown in figure 1, Fig. 1 shows
The Organization Chart and reference point of the NFV that anticipated out management layouts (NFV-MANO, NFV Management and Orchestration).
Wherein NFV composers (NFVO, Network Functions Virtualization Orchestrator) are responsible for network service
Life cycle management, the network of across virtual architecture manager (VIM, Virtualised Infrastructure Manager)
Virtualization of function architecture (NFVI, Network Functions Virtualization Infrastructure) resource
The functions such as scheduling, VNF managers (VNFM, VNF Manager) are responsible for the life cycle management of VNF examples, and each VNF examples are false
There are the VNFM of an association, VIM to be responsible for controlling and manage NFVI calculating, storage and Internet resources.
Traditional network management uses more and includes network management (NM, Network Management), NE management (EM, Element
Management) and network element three-layer pipe reason structure.Wherein, NM is also referred to as NMS (NMS, Network
Management System), EM is alternatively referred to as Element management system (EMS, Element Management System).NM leads to
Often it is considered the part or one kind of OSS (OSS), the interface between wherein NM/OSS and EM is northbound interface, EM
It is southbound interface between network element.
The virtualization of mobile network, it is meant that traditional network element (network function node) will be virtualized, conventional network elements
Network function will be realized by VNF, but the not necessarily man-to-man relation of traditional network element and VNF, a VNF also may be used
The function of multiple network function nodes can be realized, as shown in Figure 2.For traditional network management, increase a network function node,
It is exactly to need to increase a network element device accordingly, when conventional network elements and VNF are man-to-man relations, namely exists accordingly
Increase a single VNF in network.But when a VNF realizes multiple network function nodes, operator will increase
Or reduce by a network function node, it might not seek to increase or decrease a single VNF, may be needs pair
VNF part VNF components (VNFC, VNF Component) are operated, and current management system has to such case
The solution of effect.
