Description
Technical field
The present invention relates to network virtualization technology, more particularly to a kind of virtualization network function instantiation method and device.
Background technology
In the management domain of wireless telecommunication system, NMS (NMS, Network Management System)
Interface between Element management system (EMS, Element Management System) is referred to as northbound interface (Itf-N).
EMS mainly completes International Telecommunication Union (ITU, International Telecommunication Union) telecommunication administration
NE management layer (EML, Element in network (TMN, Telecommunications Management Network)
Management Layer) function, that is, the management function of one or more mobile communication equipments is completed, is typically different equipment supply
EMS between business can not be general.NMS mainly completes the NML functions in ITU TMN, is responsible for all network elements in a managed network
Management.For multiple equipment supplier be present in managed network (being referred to as subnet), can be managed by respective EMS
Reach the purpose for managing whole subnet.
At present, in order to improve the flexibility of communication network, management cost is reduced, is initiated to propose network function by operator
(NFV, Network Functions Virtualization) concept is virtualized, in the case of using NFV technologies, originally
Physical NE equipment is replaced by virtualization network function (VNF, Virtualized Network Function) so that network work(
It can be decoupled with particular hardware, as shown in figure 1, the network function of VNF and bottom virtualization architecture (NFVI, Network
Functions Virtualization Infrastructure) isolation.Management for VNF, VNF examples are entered by EMS
The traditional maintenance management function of row, and VNF life cycle management function is then completed by VNF managers VNFM.The void of bottom
Intend architecture to be managed by Virtual base architecture management device (VIM).And specific Network, then typically by one or
Multiple VNF examples are completed.Management to Network, then carried out by NFV composers NFVO.Realize that network function is virtual
After change, from the point of view of application, it is necessary to the reality for the VNF that Mr. needs into Network when establishing a Network example
Example, then a Network example is formed by one or more VNF examples, provide Network by Network example.
Traditional network management structure generally includes NMS/ OSSs (OSS, Operation support
System), the three-layer pipe of EMS and network equipment reason structure；Wherein, the interface between NMS and EMS is northbound interface, EMS and net
Interface between network equipment is southbound interface.NMS will turn to one on northbound interface per class network device model
Management information object class, each network equipment can have the information object example of an affiliated object class, with mark (DN,
Distinguish Name) represent, include the configuration information of belonging network equipment in information object example；Management system passes through
Establishment, deletion and renewal to information object example are operated to complete the management to configuring information of network appliance, and the network equipment is made
Will not dynamic change for management entity.
After network equipment virtualization, network function is realized on VNF, and the configuration information of network function also only exists
In VNF life cycle effectively.VNF life cycle management includes：VNF instantiations (Instantiate VNF), VNF examples
Terminate (Terminate VNF), VNF examples adjust (Scale VNF) and the renewal of VNF examples etc..
The foundation of instantiation and its corresponding management object for VNF, current scheme is first to instantiate VNF, in NMS
Or after EMS receives the message that VNF instantiations are completed, then initiate to create corresponding management object.But this mode is with traditional net
Network way to manage difference, it is necessary to which operator has bigger change to existing management process.And promoting network function
At the initial stage of virtualization, operator needs to change its existing management process as little as possible, and there is an urgent need to corresponding VNF instantiation sides
