Develop into the cloud communication network of software and hardware separation based on the private network device of the soft or hard combination of system, to accelerate business
Development deployment speed, is effectively reduced operation cost.
NFV system is mainly made of three parts: multiple virtual network function (Virtualised Network
Function, VNF), network function virtualized infrastructure (NFV Infrastructure, NFVI) and NFV management and layout
(Management and Orchestration, MANO).Wherein, MANO virtualizes composer (Network by network function
Function Virtualisation Orchestrator, NFVO), virtualization network function manager (Virtual
Network Function Manager, VNFM), virtualized infrastructure manager (Virtual Infrastructure
Manager, VIM) three parts composition.About VNF resource management scheme, European Communication Standard association (European Telecom
Standard Institution, ETSI) propose two kinds of mode standards:
Direct Model: operation that VNFM proposes to be managed from VNF to NFVO (such as the instantiation of VNF, dilatation, capacity reducing,
Termination, software upgrading etc.) request, NFVO is according to operation requests and whole resource situation return authorization.VNFM is obtaining NFVO's
After authorization, schedule virtual resources (such as distribution, modification, authorization of virtual resource etc.) directly is carried out with VIM.VNFM is anti-to NFVO
Present virtual resource alteration.
Indirect pattern: authorization stages are identical as Direct Model, and unlike Direct Model, VNFM is obtaining awarding for NFVO
Quan Hou, VNFM propose the relevant schedule virtual resources request of VNF to NFVO according to Authorization result, by NFVO according to the net of virtualization
Network functional module descriptor (Virtualised Network Function Descriptor, VNFD) is by schedule virtual resources
Request is decomposed into one or more schedule virtual resources and operates and interact completion realization scheduling of resource with VIM.NFVO is anti-to VNFM
The case where presenting virtual resource change.

On the basis of connecing mode, NFVO is forwarded processing as agency, by schedule virtual resources request between VNFM and VIM.Specifically
It is as follows:
Simplify indirect pattern: NFVO is that each VIM configures resource management agent.The step of authorization stages same Direct Model,
Unlike Direct Model, schedule virtual resources stage after authorizing successfully, VNFM directly with the resource management generation of NFVO
Reason interaction realizes schedule virtual resources by NFVO and VIM.VNFM feeds back virtual resource alteration to NFVO.
The shortcomings that three of the above mode, is: during to VNF resource management, when schedule virtual resources failure,
The virtual resource for participating in schedule virtual resources can be rolled back, to return to the original state before schedule virtual resources.When system again

Letter carries out resource allocation and exchanges the configuration and status information of virtualization hardware resource.
The embodiment of the present application provides a kind of method of NFV resource management, as shown in Fig. 2, this method may include S201-
S203:
S201, NFVO determine that VNF management operates corresponding at least one schedule virtual resources operation.
Wherein, VNF management operation includes instantiation, dilatation, capacity reducing, termination, the update etc. to VNF.Virtual resource includes
Virtual computing, virtual memory in NFVI virtualization layer, virtual network.
Schedule virtual resources operation is the scheduling operation that carries out to virtual resource in order to complete NFV resource management action.
Compared to VNF resource management action, it is to virtual resource most granule that schedule virtual resources operation, which is more refinement, more basic operation,
The scheduling operation of degree, can the VIM in NFV system as shown in Figure 1 execute.Schedule virtual resources operation specifically includes virtual
The operation such as computing resource, virtual storage resource, the creation of virtual network resource, deletion.
Optionally, under NFV indirect pattern, this step is specifically as follows: VNFM sends VNF management operation to NFVO.
NFVO receives the VNF that VNFM is sent and manages operation, and VNF management operation is then decomposed into several schedule virtual resources according to VNFD
Operation.
Wherein, VNFD is the deployment for describing VNF and the configuration template of operation behavior.VNF management operation is described in VNFD
With the corresponding relationship between schedule virtual resources operation.Because a VNF management operation may need multiple schedule virtual resources
It is just able to achieve, so needing that VNF management operation is refined as more refinement according to VNFD, more basic schedule virtual resources operate.
Optionally, in the case where NFV simplifies indirect pattern, this step is specifically as follows: NFVO receives the VNF management that VNFM is sent
Operate corresponding at least one schedule virtual resources operation.Determine that VNF management operates that corresponding at least one is virtual by VNFM
Scheduling of resource operation, then the operation of these schedule virtual resources is sent to NFVO.For example, NFVO receives the wound that VNFM is sent
The VNF management operation of firewall is built, then it is empty for creation to determine that the creation both firewall operations correspond to schedule virtual resources operation by VNFM
Quasi- machine, distribution network interface etc., then VNFM will create the schedule virtual resources operations such as virtual machine, distribution network interface and be sent to
NFVO。
Optionally, in the case where NFV simplifies indirect pattern, resource pipe is configured with for each VIM on the NFVO in the present embodiment
Reason agency.Resource management agent is used to forward the communication information between VNFM and VIM, and VNFM is allowed to require no NFVO master
Body can be managed VIM.Meanwhile in the present embodiment, resource management agent can also provide VNFM pipe to NFVO main body
Manage the scheduling operation information of VIM.
If the operation of S202, schedule virtual resources is creation virtual resource, NFVO is in the virtual resource for being in buffer status
Middle determination and schedule virtual resources operate matched destination virtual resource.
Specifically, NFVO is in the void for being in buffer status if schedule virtual resources operation is VNF creation virtual resource
The virtual resource type and the identical virtual resource of configuration found in quasi- resource and created needed for schedule virtual resources operation, this
The virtual resource that sample is found is destination virtual resource.
For example, when schedule virtual resources operation is the operation of one 100MB virtual memory of creation, then NFVO searching is
It is no to there is the 100MB virtual storage resource for being in buffer status.A 100MB virtual memory in buffer status provides if it exists
Source, then the virtual storage resources are destination virtual resource.Similarly, if schedule virtual resources operation is virtual for one double-core of creation
The operation of core is calculated, then NFVO looks for whether the double-core virtual computing core for having in buffer status.If it exists at one
In the double-core virtual computing core of buffer status, then the double-core virtual computing core is destination virtual resource.If virtual resource
Scheduling operation is the operation for creating a 100M Microsoft Loopback Adapter, then NFVO looks for whether virtual in the presence of the 100M in buffer status
Network interface card.A 100M Microsoft Loopback Adapter in buffer status if it exists, then the 100M Microsoft Loopback Adapter is destination virtual resource.
In the embodiment of the present application, the virtual resource in buffer status mentioned above refers in rolling back action, needs
Deletion but creation virtual resource that is not deleted but being retained.It is executed back after any VNF manages operation failure
Rolling operation, if the rolling back action includes the operation for deleting virtual resource, virtual resource to be deleted is arranged the NFVO
For buffer status.
Specifically, NFVO determines the mark for the virtual resource deleted needed for the operation for deleting virtual resource in the present embodiment.
Mark of the NFVO according to these virtual resources, the virtual resource deleted needed for finding, and be the label of its setting buffer status.Together
When, schedule virtual resources operation is not issued VIM by NFVO, i.e. VIM is for being provided with the virtual resource of buffer status without deleting
Except operation.In this way, the virtual resource deleted is needed to be retained them temporarily by being provided with buffer status originally, so as to
Operation is managed for subsequent VNF to utilize.
Optionally, the process that virtual resource to be deleted is set buffer status by above-mentioned NFVO can also be slow by establishing
State set is rushed, the mode that the buffer status set is added in the mark of virtual resource to be deleted is realized.
S203, NFVO activate destination virtual resource.
Specifically, above-mentioned activation are as follows: NFVO cancels the label of the buffer status of destination virtual resource, so that target is empty
Quasi- resource can be managed in operation in VNF and be used.By activating destination virtual resource, destination virtual resource is directly used
This creation virtual resource operation is completed, without creating a new virtual resource again.
It is worth noting that after S203 is finished, showing that the operation of this schedule virtual resources is complete in the present embodiment
At then NFVO directly sends the feedback information that this schedule virtual resources operates to VNFM, without sending virtual resource tune to VIM
Degree operation.
Optionally, after S201, if NFVO can not be determined in the virtual resource in buffer status and virtual resource
Schedule virtual resources operation is then sent to VIM by the matched destination virtual resource of scheduling operation.VIM is receiving virtual resource tune
After degree operation, is operated according to schedule virtual resources, execute corresponding schedule virtual resources.For example, schedule virtual resources operation is
2GB virtual memory is created, and does not have the virtual memory of 2GB in the virtual resource under buffer status, then NFVO is by the virtual money
Source scheduling operation is sent to VIM.VIM can create the virtual memory of a 2GB according to the schedule virtual resources.
Furthermore, it is contemplated that will cause the waste of system resource if the virtual resource of buffer status is not used by for a long time,
The present embodiment increases following steps in above-mentioned steps to solve this problem:
It is after buffer status is arranged in virtual resource in NFVO, NFVO is that timing is arranged in the virtual resource in buffer status
Device, the timer is used for after by preset time, by the virtual resource rollback in buffer status.NFVO for
After virtual resource setting timer in buffer status, the timer state of virtual resource can be monitored.If some virtual resource
The preset time of timer be already expired, then NFVO notifies VIM by the virtual resource rollback, to discharge the virtual resource.
It is corresponding, in step S203, determined and the virtual money in the virtual resource in buffer status in NFVO
After the matched destination virtual resource of source scheduling operation, further includes: NFVO deletes the corresponding timer of the destination virtual resource.
Meanwhile it being based on the above method, and in S202, NFVO determining and virtual money in the virtual resource in buffer status
When the matched destination virtual resource of source scheduling operation, if occurring multiple to operate the virtual moneys that match with schedule virtual resources
When source, a timer remaining time the smallest virtual resource can be selected according to the time of the corresponding timer of virtual resource
As destination virtual resource.
The method of NFV resource management provided by the present application, when executing the operation of creation virtual resource in NFV system,
It can be determined from the virtual resource in buffer status and operate matched destination virtual resource with the schedule virtual resources and swash
Destination virtual resource that it serves somebody right, can complete the operation of creation virtual resource.The target void of buffer status is in by calling directly
Quasi- resource, it is no longer necessary to create new virtual resource, avoid and virtual resource is scheduled again, to reduce VNF management
The time delay of operation.
