Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 6 is the flow chart of the processing method taking situation according to the target resource of the embodiment of the present invention.As shown in Figure 1, the processing method that this target resource takies situation can comprise:
Step S602: the target resource obtaining VNFscaleup and/or scaledown takies situation;
Step S604: take the virtual machine for subsequent use that situation instruction VIM creates or amendment is corresponding with VNFC for subsequent use according to target resource, wherein, the business that virtual machine for subsequent use is being carried out for taking over the primary virtual machine corresponding with primary VNFC.
The detailed settlement project for graceful elastic telescopic is lacked in correlation technique.Adopt method as shown in Figure 6, in the process of scaleup/scaledown, NFVO can take situation according to the target resource of VNFscaleup/scaledown and indicate virtual architecture to manage (VirtualizedInfrastructureManager, referred to as VIM) create (being applicable to the situation that dereliction in VNF is standby) or amendment (being applicable to there is active and standby situation in VNF) virtual machine that VNFC for subsequent use is corresponding, owing to there being VNFC adapter business for subsequent use, maintain business without impact or less impact, thus solve in correlation technique VNF elasticity stretch and/or elasticity contracting process in, the problem of the business of normally carrying out cannot not be affected under the occupation condition of amendment VM, and then achieve graceful scaleup/scaledown, improve the availability of VNF.
Preferably, in step S604, after taking situation instruction according to target resource VIM creates virtual machine for subsequent use, following operation can also be comprised:
Step S1: after virtual machine for subsequent use starts startup, trigger primary virtual machine to virtual machine synchrodata for subsequent use;
Step S2: when determining that the process of synchrodata has entered stable state, triggers primary virtual machine and virtual machine for subsequent use is switched, and after switching operation terminates, deletes primary virtual machine.
In a preferred embodiment, inner for VNF VNFC can be divided into two kinds of situations: have active and standby standby with dereliction; The meaning of VNFC for subsequent use is (may be primary VNFC fault, overhaul of the equipments etc.) to take over the business performing primary VNFC as required.Whether VNF has active and standby is describe in the virtual network function descriptor (Virtualnetworkfunctiondescriptor, referred to as VNFD), and whether the VNFC that NFVO and VNFM can perceive VNF by VNFD has active and standby.There is active and standby and dereliction for two kinds of situations for VNF inside VNFC, for the situation that VNF inside VNFC dereliction is standby, active and standby function also can be utilized to reach the object of graceful scaleup and scaledown.Compared with having active and standby situation with the inner VNFC of VNF, first need the VNFC to being about to carry out scaleup/scaledown to create VNFC for subsequent use, the virtual machine that this VNFC for subsequent use is corresponding takies situation according to the target resource of scaleup/scaledown to create.Then start to start virtual machine corresponding to VNFC for subsequent use, trigger virtual machine corresponding to primary VNFC to virtual machine synchrodata for subsequent use (such as: the synchrodata function of live migration of virtual machine), after synchrodata enters stable state, trigger masterslave switchover (such as: the handoff functionality of live migration of virtual machine), after masterslave switchover terminates, delete the virtual machine that former primary VNFC is corresponding, the process of scaleup/scaledown just finishes.In this process, owing to there being VNFC adapter business for subsequent use, maintain on business without impact or less impact, achieve graceful scaleup/scaledown function.
In preferred implementation process, after switching operation terminates, VIM can be indicated to delete primary virtual machine.
For there being active and standby situation in VNF, after masterslave switchover terminates, then graceful scaleup/scaledown just completes, and for the situation that dereliction in VNF is standby, after masterslave switchover terminates, NFVO indicates VIM to delete virtual machine corresponding to new VNFC for subsequent use.
Preferably, in step S604, after taking situation instruction according to target resource VIM revises virtual machine for subsequent use, can also comprise the following steps:
Step S3: after virtual machine for subsequent use restarts, detects primary virtual machine and whether enters stable state to the process of virtual machine synchrodata for subsequent use;
Step S4: when determining to enter stable state, triggers primary virtual machine and virtual machine for subsequent use is switched;
Step S5: after the occupation condition of the virtual machine for subsequent use after switching is modified, restart the virtual machine for subsequent use after switching.
In a preferred embodiment, active and standby situation is had for VNF inside VNFC, this active and standby function can be utilized to reach the object of graceful scaleup and scaledown, namely first take situation according to the target resource of scaleup/scaledown and revise virtual machine corresponding to VNFC for subsequent use and restart virtual machine.After virtual machine activation for subsequent use, primary virtual machine is to dynamic synchronization data for subsequent use, and after synchrodata enters stable state, trigger masterslave switchover, virtual machine for subsequent use becomes primary virtual machine, and primary virtual machine then becomes virtual machine for subsequent use.Then, revise the occupation condition of new virtual machine for subsequent use, restart new virtual machine for subsequent use, the process of scaleup/scaledown just finishes, in this process, owing to there being VNFC adapter business for subsequent use, maintain on business without impact or less impact, achieve graceful scaleup/scaledown function.
In preferred implementation process, when determining that the process of synchrodata has entered stable state, notice VNF triggers primary virtual machine and virtual machine for subsequent use is switched, and takes over the current business of carrying out of primary virtual machine by virtual machine for subsequent use.
After synchrodata enters stable state, NFVO notifies that VNF triggers VNFC masterslave switchover, and taken over the virtual machine business of primary VNFC by the virtual machine of VNFC for subsequent use, former primary VNFC becomes VNFC for subsequent use, and former VNFC for subsequent use becomes primary VNFC.
In preferred implementation process, situation can be taken by NFVO or VNFM according to target resource and indicate VIM create or revise virtual machine for subsequent use.If perform Resourse Distribute by VNFM, then take situation by VNFM according to the target resource of VNFscaleup/scaledown and indicate VIM to create (being applicable to the situation that dereliction in VNF is standby) or amendment (being applicable to there is active and standby situation in VNF) virtual machine that VNFC for subsequent use is corresponding; If perform Resourse Distribute by VNFM, for there being active and standby situation in VNF, after masterslave switchover terminates, then VIM is indicated to delete virtual machine corresponding to new VNFC for subsequent use by VNFM.
