Description

NFV strategy consulting method and system

Technical field

This application involves computer field more particularly to a kind of NFV strategy consulting method and systems.

Background technique

A kind of network function that the prior art as shown in Figure 1 provides virtualizes (network functions Virtualization, NFV) architecture diagram, the framework of NFV is divided into two management domains: one is 3GPP management domain, mainly Including in left frame network management (network management, NM) and NE management (element management, EM), mainly application level can also consider the information of resource layer to the O&M of operation layer；Another is management and layout The domain (management and orchestration, MANO), left frame as shown in figure 1, which is mainly responsible for network service The Life Cycle of (network service, NS) and virtual network function (virtual network function, VNF) entity Period management is the O&M in resource level.

A kind of frame diagram of the progress tactical management in domain MANO that the prior art as shown in Figure 2 a provides, tactical management point (policy administration point, PAP) concentrates the publication for making policing rule, policy decision point (policy Enforcement point, PF) it is distributed in network function virtualization composer (network function Virtualization orchestrator, NFVO), VNF manager (VNF manager, VNFM) and Virtual base facility pipe Local decision-making is done in reason (virtual infrastructure management, VIM).This framework needs on NFV framework Increase new component.

The frame diagram of the progress tactical management in another domain MANO that the prior art as shown in Figure 2 b provides, proposes one The concept of the distributed PAP of kind, the function of PAP are separately positioned in multiple network elements.This framework NFV framework is without increasing new portion Part.

Either distributed or centralization PAP makes the life cycle of NS and VNF by MANO policy management framework Management, self-healing and virtual resource management can carry out automatically.

The accident analysis and self-healing that EM/NM can also be automated.EM from network element and VNFM acquisition warning information and on Offer the fault detection that NM, EM and NM can be automated in its range of management, failure root cause analysis and self-healing movement It issues.Therefore, if realizing automation fault management by policy-driven, NM and EM all can serve as Policy Enforcement Point.

A kind of policy-driven that the prior art as shown in Figure 3 provides realizes the automation fault management of 3GPP management domain Flow diagram, the process the following steps are included:

Step 1a: non-virtualized NE (i.e. physical network function (physical network shown in Fig. 1 Function, PNF)) network element is to EM report and alarm；

Step 1b: the NE (for example, VNF A) of virtualization to EM report and alarm: traffic bursts rise, big comprising receiving Measure abnormal service message；

Step 1c:VIM reports the alarm of resource layer inadequate resource to VNFM；

Step 2:VNFM carries out being associated between resource layer and VNF, sends the relevant virtual resource alarm of VNF A to EM, VNF A resources occupation rate reaches alarming threshold value；

The alarm being collected into from each source is sent Operation Support System (operational by step 3:EM Support system, OSS) (specifically can be NM)；

Step 4:EM carries out strategic decision-making according to the accident analysis policing rule being arranged thereon, carries out fault correlation and failure Root cause analysis.Different environmental contexts can lead to different strategic decision-making, and EM may make the different decision of following two:

A wrong business configuration on step 5a (option 1): EM discovery VNF B, causes VNF B to send out to VNF A A large amount of service message is sent, wherein the message also comprising many mistakes.EM issues change configuration order to VNF B, on VNF A Portfolio restores normal；

Step 5b (option 2): EM decision should carry out dilatation to VNF A, then EM sends relevant Life Cycle to VNFM Period management message.After VNF A dilatation, alarm is eliminated.

There are multiple policy decision point in current 3GPP network management framework (including MANO).Lead on these policy decision point The policing rule for often configuring this domain, the environmental context for doing strategic decision-making is also not global information, but letter obtained by this domain Breath.Strategy execution in MANO is operated generally by virtual resource of the VIM to NFVO.The strategy execution of NM and EM is usual It is the configuration to VNF, or operated by VNFM/NFVO to virtual resource.Different policy decision point (such as EM and VNFM the strategy between), which lacks, to be coordinated, such as:

1. business configuration causes burst a large number of services flow to issue from upper can trigger of VNF A to VNF B, EM to VNF A The order for modifying configuration, by partial service conductance to VNF C, and VNFM may be triggered according to resource policy preset in VNFD Dilatation to VNF B.

2. because resource occupation caused by operation layer internal software error is abnormal, upper can trigger of EM restarts thread to VNF, The movement such as software is updated, and the strategy of VNFM may be to carry out dilatation to the VNF of inadequate resource.

3. because of reasons such as LB configuration or user are mobile, part network element resources occupancy is too high, other part network element money Source occupancy is too low.EM is upper can be triggered to VNF configuration modification to adjust portfolio to " spare time " network element, and the strategy of VNFM may Scalable appearance operation is carried out, the movement of the two may generate conflict, form concussion.

Virtual network 4. (such as vSwitch) failure, MANO carries out resource layer processing according to preset strategy, but EM because It inputs that information input is insufficient, and erroneous judgement is VNF application layer failure, and VNF is restarted or the operations such as configuration modification.

The environmental context of 3GPP management domain and each own policy decision point of MANO management domain, implementation strategy is different, strategy The execution point of decision may also be different, may make repeated and redundant in operation layer and resource layer for the same exception, or A contradictory or correct wrong decision, and respectively according to the strategy execution of oneself.

Therefore, in NFV framework, it is to need what is solved to ask at present that how each policy decision point, which carries out correct strategic decision-making, Topic.

Specific embodiment

The embodiment of the present invention is described with reference to the attached drawing in the embodiment of the present invention.

The embodiment of the present application can be applied in the framework of NFV shown in FIG. 1, be certainly not limited to the frame of NFV shown in FIG. 1 Structure.It can be applied to the policy conferring between arbitrary two policy decision point.

As shown in Figure 1, in 3GPP management domain, from top to bottom, including Operation Support System (operational support System, OSS)/business support system (business support system, BSS), equipment management (device Manager, DM) and network function (network function, NF) entity.Wherein, OSS/BSS is the fortune of entire NFV framework Battalion/business support system is responsible for operation/business of management whole system.OSS/BSS is in addition to traditional management function, for void Quasi-ization application interacts the operation and maintenance completed to network with NFVO.It mainly include EM in DM.NF entity includes physical network function It can (physical network function, PNF) entity and VNF.VNF is related generally in the application.

In MANO management domain, from top to bottom, including NFVO, VNFM and VIM.Wherein, NFVO major function is to realize operation The function such as NS life cycle management (such as deployment/dilatation/capacity reducing/offline) and the layout of NFVI resource, tactical management in the quotient field Energy.NFVO decomposites the demand to each VNF according to NS information model descriptor (NS descriptor, NSD), and cooperation VNFM is real The deployment of existing VNF.VNFM major function is to realize the life cycle management of VNF, such as deployment/dilatation/capacity reducing/offline automation Ability.VNFM decomposites the demand to virtual resources such as virtual machines according to template and VNF capacity requirement, with Orchestrator, The instantiation of VNF is completed in VIM cooperation.VIM major function is realized to entire infrastructure layer resource (containing calculating, storage, network Resource) management and monitoring.

Network element software may operate in network element on various general hardware by NFV；And by MANO system, by net Member deployment process automation；Operator can need quickly dynamically to carry out scalable appearance according to business.

The NM and EM of 3GPP management system can be abstracted into PDP.If failure/exception is handled in EM analysis, EM is PDP；If it is cross-domain across EM scene, NM is needed to do failure/exception analysis processing, then NM is PDP.In 3GPP management system Final Policy Enforcement Point may be that VNF (executing operation layer configuration or operation) or VNFM (execute VNF Life Cycle Management Relevant operation will finally operate resource by NFVI).Inside 3GPP management system, different policy decision point holds Easily cooperation.For example, the strategy of OSS will be handed down to EM, the strategy of EM oneself can take into account the strategy of OSS, for VNF, no It will receive more than one conflicting strategy.The strategy that EM is sent to VNF is sent to the strategy of VNFM with EM, because strategy is What unification was sent out from EM, so the strategy that strategy and VNFM that VNF is executed execute will not be conflicting.

The policy decision point of MANO management system may be NFVO, VNFM or VIM, and final Policy Enforcement Point is NFVI.Three policy decision point are divided the work, and ensure that the same event will not trigger multiple policy decision point in process Carry out strategic decision-making.

The application is the establishment strategy negotiation mechanism between the PDP of the PDP and MANO management system of 3GPP management system.It keeps away Exempt from two management systems and makes contradiction or duplicate strategy.

The embodiment of the present application provides a kind of NFV strategy consulting method and system, and each policy decision point of different management domains is logical Carry out policy conferring is crossed, correct strategic decision-making can be made, the policy decision point of not same area is avoided to make contradiction or duplicate Strategic decision-making.

As shown in figure 4, be a kind of interaction flow schematic diagram of NFV strategy consulting method provided by the embodiments of the present application, it should Method can comprise the following steps that

S101, the first network element receive strategy request information, according in the local policy of the first network element and the solicited message The strategy request cause parameter of carrying generates the first strategy.

S102, the first network element sending strategy negotiation request message to the second network element, wherein first network element and institute It states the second network element and belongs to different NFV management domains, the policy conferring request message includes: strategy request cause parameter, first The priority of strategy and the first strategy.Second network element receives the policy conferring request message.

The reason of S103, second network element are carried according to policy conferring request message parameter carries out Policy evaluation, Generate the second strategy.

S104, second network element compare the priority of the first strategy and the second strategy, generate corresponding strategy instruction letter Breath.

S105, second network element send the strategy instruction information to first network element.First network element receives The strategy indicates information.

S106, first network element execute the strategy instruction information.

In S101, the first network element receives strategy request information.First network element can be the network element of 3GPP management domain, It can be the network element in the domain MANO.In the present embodiment, policy decision point of first network element as affiliated NFV management domain.This first Network element can receive the strategy request information from other network elements of the affiliated NFV management domain of the first network element.The strategy request packet Include strategy request cause parameter.The strategy request cause parameter includes resource early warning or breaks down.It makes wherein, resource early warning Alerted including resource alarm, business load etc..Resource alarm can refer to that VNF configuration is insufficient, and business load alarm can refer to some Load too low or excessively high on VNF.

The policy decision point of different NFV management domains can make difference according to local policy and the strategy request cause parameter Strategy.If such as the first network element is the policy decision point of 3GPP management domain, may be excluded in business load or application failure On make strategy；It, may be in configuration resource or virtual-machine fail row if the first network element is the policy decision point of MANO management domain Except above making strategy.In this step, the first network element is according to the plan carried in the local policy of the first network element and the solicited message Slightly reason for claim parameter generates the first strategy.

It makes in the present embodiment, it is contemplated that avoid the policy decision point of operation layer and resource layer from making contradiction or again The strategy of multiple redundancy should carry out policy conferring with the second network element when the first network element makes first strategy.Therefore, it carries out extremely S102, the first network element sending strategy negotiation request message to the second network element.First network element is in different pipes from the second network element Manage domain.For example, the second network element is the network element in the domain MANO if the first network element is the network element (for example, EM, NM) of 3GPP management domain (such as NFVO, VNFM or VIM)；If the first network element is the network element (such as NFVO, VNFM or VIM) in the domain MANO, then second Network element is the network element (for example, EM, NM) of 3GPP management domain.In addition, the first network element can also be same with the second network element with reference to Fig. 1 The network element of the different management domains of one level.For example, the second network element is NFVO if the first network element is NM；If the first network element is EM, Then the second network element is VNFM.

The policy conferring request message includes: the priority of strategy request cause parameter, the first strategy and the first strategy. Wherein, in entire NFV framework, tactful priority can be unified setting.

Second network element receives the policy conferring request message.And proceed to S103.

In S103, the reason of second network element is carried according to the policy conferring request message parameter, carry out strategy Assessment generates the second strategy.Specifically, the second network element is after receiving the policy conferring request message, according to cause parameter Difference, using different Policy evaluation modes.If the cause parameter is resource early warning, where obtaining second network element The resource and load information of each VNF of other network elements acquisition of NFV management domain, generates for the VNF's for causing resource early warning Second strategy；If or the cause parameter is to break down, and judges whether to be answering for NFV management domain where second network element With or virtual machine configuration occur mistake, generate to application or virtual machine reconfigure second strategy.For example, if cause parameter is Resource early warning, the second network element are the network elements of 3GPP management domain, then the second network element checks every dynamic value of current FCAPS, analysis The application layer configuration of each network element and the network traffic information of operation layer, generate the second strategy in network service.If the second net Member detection is the load excessive of some NFV, then makes the second strategy of transferring load, if the loading problem of NFV is not present in detection, Then indicate that the first network element executes the first strategy.If cause parameter is to break down, it may be possible to which application or virtual machine configuration cause to send out Raw failure, if the second network element is the network element of 3GPP management domain, the second network element detect whether be using caused failure, if so, Second strategy is made to application configuration, if it is not, then indicating that executing the first network element executes the first strategy

After second network element generates the second strategy, proceed to S104.In S104, the second network element compares the first strategy and first The priority of strategy generates corresponding strategy instruction information.Strategy instruction information includes at least one following instruction information: being referred to Show that first network element executes first strategy, instruction first network element does not execute first strategy and instruction institute The first network element is stated to execute to the third strategy after first Developing Tactics.

Specifically, S104 includes:

If the priority of first strategy is higher than the priority of second strategy, second network element generates instruction institute The first network element is stated to execute the described first tactful strategy instruction information or generate instruction the first network element execution to described first The strategy instruction information of third strategy after Developing Tactics；

If the priority of second strategy is higher than the priority of first strategy, second network element generates instruction institute State the strategy instruction information that the first network element does not execute first strategy.

Since the first network element belongs to different management domains, the first strategy and the second net that the first network element generates from the second network element The second strategy that member generates is the strategy of different level respectively, for example, the first strategy is the strategy for adjusting business load, the second plan It is slightly then the strategy for adjusting the resource of VNF.It is finally that the second network element agrees to that the first network element executes the first strategy or the second network element It disagrees the first network element and executes the first strategy, it is tactful by the second network element execution second, it, can be according to strategy in this implementation Priority determined, the priority of the even first strategy is higher than the priority of the second strategy, then the second network element generates instruction the One network element executes the strategy instruction information of the first strategy；If the priority of the first strategy is lower than the priority of the second strategy, the Two network elements generate the strategy instruction information that the first network element of instruction does not execute the first strategy, then the second network element executes the second strategy.

Although the priority of the first strategy, higher than the priority of the second strategy, the second network element thinks that the first network element is held The first strategy of row not can solve resource alarm or debugging, need to be adjusted the first strategy.Therefore, the second network element generates Strategy instruction information, strategy instruction information are used to indicate the execution of the first network element to the plan of the third strategy after the first Developing Tactics Slightly indicate information.For example, the first strategy is 30% load on VNF A to be reconfigured to VNF B, but the second network element combines The resource information of VNF A and VNF B, it is believed that shift 30% load it is inadequate, VNF A is still likely to occur resource alarm, then the Two network elements can indicate that the first network element transfer 40% loads to VNF B.

After the second network element generates corresponding strategy instruction information, then carry out to S105, the second network element sends the strategy and refers to Show information to the first network element.According to implementation above-mentioned, then strategy instruction information includes at least one following instruction information: Indicate that first network element executes first strategy, instruction first network element does not execute first strategy and instruction First network element executes the first strategy adjusted.

First network element receives strategy instruction information.Further the first network element executes strategy instruction information.

Specifically, in one implementation, if the strategy instruction information includes indicating that first network element executes institute The strategy instruction information of the first strategy is stated, then first network element executes first strategy.Accordingly, although the second network element is made The second strategy, but the priority due to the priority of the second strategy lower than the first strategy are gone out, then the second network element is without executing the Two strategies.

In another implementation, if the strategy instruction information includes indicating that first network element does not execute described the One strategy, then first network element does not execute the strategy instruction information of first strategy.Accordingly, due to second strategy it is excellent First grade is higher than the priority of the first strategy, and the second network element indicates that the first network element does not execute the first strategy, and the second network element itself executes Its second strategy made.

In another implementation, if the strategy instruction information includes indicating that the first network element execution is adjusted First strategy, then first network element executes the instruction information to the third strategy after the first Developing Tactics.Accordingly, the second net Although member made second strategy, due to second strategy priority lower than first strategy priority, then the second network element without The second strategy need to be executed.Simultaneously as the first strategy may not be able to solve resource alarm or debugging, need to the first strategy It is adjusted, then the second network element can be adjusted the first strategy, obtain third strategy, and the first network element of instruction executes third plan Slightly.

As it can be seen that using the NFV strategy consulting method of the embodiment of the present application, each policy decision point of different management domains by into Row policy conferring can make correct strategic decision-making, and the policy decision point of not same area is avoided to make contradiction or duplicate strategy Decision.

Describe how each decision point carries out policy conferring below by two exemplary communication scenes:

Scene 1, VNFM negotiate to EM request strategy:

By taking strategy request cause parameter is resource alarm as an example, Fig. 5 is the NFV strategy association in a kind of exemplary communication scenes The interaction flow schematic diagram of quotient's method, this method can comprise the following steps that

S201, VIM obtain CPU usage from VNFI and alarm more than the resource of threshold value.

S202, VIM notify the cpu resource to alert to VNFM.

Resource alarm is associated with VNF A by S203, VNFM.The policing rule according to described in VNFD will be triggered to VNF A Carry out dilatation.But local policy also requires the strategy to need and Element management system (element management System, EMS) carry out policy conferring.Wherein, EMS includes one or more EM.

S204, VNFM are to EMS sending strategy negotiation request message.The policy conferring request message carries following information: this The priority P ri1 of ground implementation strategy, strategy execution reason (CPU usage is more than threshold value) and strategy execution act (VNF A Dilatation is to a certain concrete specification).

After S205, EMS receive the policy conferring request message, trigger policy assessment, check current erroneous, configuration, Account, performance and safety (fault, configuration, accounting, performance and security, FCAPS every dynamic value).Analyze the application layer configuration of each network element in network service and the network flow letter of operation layer Breath is the discovery that VNF B has sent the message of a large amount of mistakes to VNF A, causes VNF A business load excessively high.According to what is set Strategy, EMS can carry out business configuration change to VNF B and solve this problem.And this tactful priority is higher.

S206, EMS negotiate response message to VNFM sending strategy, and instruction does not carry out dilatation to VNF A.

S207, EMS send business configuration order to VNF B, and the mistake configured before amendment stops VNF B to VNF A Send the message of a large amount of mistakes.

Portfolio on VNF A declines quickly, and CPU usage is normal, Failure elimination.

In this example, if VNFM does not carry out policy conferring with EMS, VNFM makes the strategy to VNF A dilatation, and EMS It does not control VNF B and stops the messages for sending a large amount of mistakes to VNF A, even if then VNF A dilatation is to fairly large, VNF A's The problem of CPU usage is more than threshold value still cannot solve, and waste resource.Negotiated by VNFM and EMS, so that in industry Business layer and resource layer will not make the decision to make mistake.

Scene 2, EM negotiate to VNFM request strategy:

By taking strategy request cause parameter is resource alarm as an example, Fig. 6 is the NFV strategy in exemplary another communication scenes The interaction flow schematic diagram of machinery of consultation, this method can comprise the following steps that

S301, EMS acquire the traffic statistics value of multiple VNF, it is found that the business load of certain VNF is very high.

S302, EMS have found that the business load of some same types VNF is very low, can by way of changing business configuration into The adjustment of row load.But the strategy for adjusting business configuration is configured to need and VNFM consulting tactical.

S303, EMS are to VNFM sending strategy negotiation request message.The policy conferring request message carries following information: this The priority P ri1 of ground strategy, strategy execution reason (VNF A load too high) and strategy execution movement (are born 30% business Load reconfigures on VNF B).

After S304, VNFM receive the policy conferring request message, the void of VNF A and VNF B are inquired in trigger policy assessment Trigger policy is carried out dilatation to VNF A by quasi- resource situation, discovery, carries out capacity reducing to VNF B.This is tactful due to local Priority is lower, determines the strategy for adopting EMS, local temporarily not trigger scalable appearance, until the effect of the strategy execution on EMS.

S305, VNFM negotiate response message to EMS sending strategy, and the strategy execution of EMS is agreed in instruction.

S306, EMS send business configuration order to VNF A and VNF B, adjust respective business load.

The upper scalable appearance strategy that will not be triggered to VNF A and VNF B of VNFM, the load of VNF A and VNF B pass through operation layer Configuration change reach balanced.

As a kind of possible implementation, S305 is also possible to be the strategy execution for indicating refusal EMS.In this case, VNFM may trigger the scalable appearance operation of strategy execution of oneself.

As alternatively possible implementation, S305 is also possible to be instruction EMS execution strategy adjusted, such as will 40% business load of VNF A reconfigures on VNF B.

In this example, if EMS does not carry out policy conferring with VNFM, EMS is made 30% business load on VNF A It reconfigures on VNF B, and VNFM makes the strategy for carrying out dilatation to VNF A, carrying out capacity reducing to VNF B.Then when VNF A's After load configuration to VNF B, discovery VNF B but by capacity reducing, alarm by the upper resource that can cause of VNF B.Then EMS again will be on VNF B Business load part reconfigure to VNF A.Since EMS and VNFM have made contradictory strategy, " table tennis effect can be caused in this way It answers ".EMS is avoided by carrying out policy conferring with VNFM so that making contradictory strategy in operation layer and resource layer.

According to a kind of NFV strategy consulting method provided by the embodiments of the present application, each policy decision point of different management domains is logical Carry out policy conferring is crossed, correct strategic decision-making can be made, the policy decision point of not same area is avoided to make contradiction or duplicate Strategic decision-making.
