In order to reach the purpose of the embodiment of the present invention, can adopt the following technical scheme that in the embodiment of the present invention：
Scheme 1：
The first step：User passes through NFVO or VNFM and one VNF example is created with an elastic reducing and expansion appearance strategy (with above-mentioned
Reducing and expansion hold strategy).
Second step：VNF example periodic collection monitoring parameter data is simultaneously reported.
3rd step：In VNFM or NFVO regular check VNF example detection parameter values, when monitoring parameter meets elasticity contracting
During condition defined in dilatation strategy, related action in strategy is held in the automatic reducing and expansion of triggering, if policy definition is on NFVO,
Issue reducing and expansion appearance strategy and arrive the corresponding VNFM of VNF example.
Here trigger condition supports complex conditions scene, the annexation (such as and, or etc.) in supports conditions group.
If defining 5 kinds of deployment specifications f1, f2, f3, f4, f5 in VNF instantiation masterplate, if entering by deployment specification f1
The vnf instantiation of row, usually carries out reducing and expansion appearance according to f1 → f2 → f3 → f4 → f5, formulates when reducing and expansion hold tactful and allows across deployment
Specification executes, such as from f1 → f3 or f3 → f1.
4th step：Preparation is held in the automatic reducing and expansion that VNFM executes VNF example.
5th step：VNFM judges the mode (still directly specifying concrete VIM application by NFVO unified operation) of resource bid,
If by VNFM, VNFM issues reducing and expansion appearance request to specifying VIM, otherwise sends reducing and expansion appearance request and arrives NFVO, by
NFVO issues further according to resource service condition and asks to the VIM specifying.
6th step：VIM holds resource request according to reducing and expansion and carries out unified resource layout, and the resource information of distribution is returned to
NFVO or VNFM.
7th step：VNFM carries out deployment configuration parameter information renewal according to the resource information distributed and processes to VNF example.
8th step：Automatic deployment VNF example, carries out reducing and expansion appearance.
9th step：Hold the application parameter that later VNF example automatically configures correlation according to reducing and expansion.
Tenth step：The operation information log that VNFM and/or VNFO holds according to automatic reducing and expansion.
Wherein when execution when preparing is held in the automatic reducing and expansion of the 4th step VNF example, step is as follows：
VNFM reads monitoring parameter numerical value from directory service or configuration file and meets reducing and expansion appearance condition corresponding VNF deployment rule
Lattice or movement content (need to be converted into specific deployment specification), read deployment unit inventory according to corresponding deployment specification.
One by one read VNF example deployment specification include virtual deployment unit information (Virtual Development Unit, referred to as
For VDU) (VDU1, VDU2 ... VDUn).
Read example number and the longitudinal reducing and expansion that the horizontal reducing and expansion comprising in VDU (VDU corresponds to a VM void machine) are held
Hold resource allocation information (as central processing unit (Central Processing Unit, referred to as CPU), memorizer Memroy,
Storage Storage).
Reducing and expansion are formed according to VUD resource bid demand and holds transactions requests.
According to the reducing and expansion in VDU deployment unit inventory show mercy condition composition VNF example reducing and expansion hold affairs, request VNFM carry out from
Dynamic elasticity is stretched.
