101, when management entity increases to management and layout (the Network Function of network function virtualization Virtualization Management and Orchestration, NFV MANO) system when, obtain the management newly increased The tactful metamessage that entity needs support.

In embodiments of the present invention, NFV MANO system initial setting up has one or more management entities, management entity, Specifically can include: network service (Network Service, NS), and/or, virtual network function (Virtualized Network Function, VNF), management entity can also refer to for realizing the entity of other service functions, for initial setting up The tactful metamessage that needs support of management entity preserved in policy engine, user is by client from policy engine The tactful metamessage of middle extraction, client assembles definition strategy according to the tactful metamessage of extraction, by the plan of definition after the completion of definition Slightly setting comes into force into policy engine.Data set provider provides defined data content to policy engine, and policy engine is from number The data needed are executed according to acquisition strategy in supplier, according to the satisfaction of the data of acquisition judgement and policy-related (noun) rule condition Situation executes the movement set in the rule automatically when meeting policy-related (noun) rule condition, to change NFV MANO system Behavior is executed to the direction of the preset objective result of strategy.

But when NFV MANO system needs to realize new function, it is necessary to be newly increased in NFV MANO system corresponding The management entity of function is realized by updating policy engine in the prior art, this just needs the code to policy engine It is rewritten, to meet the new function that NFV MANO system needs to realize, but the update of policy engine will affect strategy The stability of engine, and after updating policy engine, the management entity newly increased possibly can not be adapted to updated strategy There is compatibility in engine.In embodiments of the present invention, in NFV MANO system for the management entity of initial setting up, Policy engine can adapt to very well, but work as new function and increased management entity that NFV MANO system needs to realize, will There are problems that generating compatibility and stability.

In embodiments of the present invention, first to whether there is new management entity addition to be examined in NFV MANO system in real time It surveys, there is the management entity that newly increases in NFV MANO system can determine, when having the pipe newly increased in NFV MANO system When managing entity, step 101 starts to execute, and gets the tactful metamessage (English that the management entity newly increased needs support first Entitled Policy metadata), wherein tactful metamessage is the metamessage for definition strategy, and policy definition process is exactly Pass through the process for being assembled into one group and tactful dependency rule to metamessage.Tactful metamessage is specific can include: conditional attribute member The restrict condition of information, movement metamessage and packaging strategy rule, is illustrated below: needing in NFV MANO system The management entity to be newly increased is VNF, and the tactful metamessage which needs support includes: that condition metamessage is user load (English Literary fame is known as userload), movement metamessage is dilatation (English name scaleout), and restrict condition is Userload/scaleout is only applicable to VNF object entity, then can be assembled by these metamessages and define a VNF life Life period relevant policing rule: when VNF (userload >=90%) then scaleout, i.e., as the userload of VNF Automatically scaleout movement is executed when greater than 90%.

In embodiments of the present invention, whether tactful realization device is real to there is new management entity to carry out in NFV MANO system When detect, when the management entity newly increased if it exists, tactful realization device gets this first against the management entity newly increased The management entity newly increased needs support the tactful metamessage of what content, for different management entities, the plan that needs support Slightly metamessage is different.Which type of tactful metamessage needs the management entity newly increased needs support by the hair of management entity Cloth side determines that publisher is in a template to the strategy member letter of support required for the management entity newly increased in NFV MANO system Breath is described, therefore tactful realization device can get tactful metamessage by the template in NFV MANO system, In some embodiments of the present invention, it is real to obtain the management newly increased when management entity increases to NFV MANO system for step 101 The tactful metamessage that body needs support, can specifically include following steps:

A1, when having detected that management entity increases to NFV MANO system, obtain the corresponding management entity of management entity Template, management entity template include: the tactful metamessage description content that management entity needs support；

A2, according to tactful metamessage description content generation strategy metamessage.

Wherein, it in step A1, when having the management entity newly increased in NFV MANO system, is saved in NFV MANO system There is management entity template, management entity template is being managed for the tactful metamessage that management entity needs support to be described Record has the description content to above-mentioned tactful metamessage in physical template, and management entity template is provided by publisher, and management is real Content format in body template needs to follow the agreement of NFV MANO system realization.Specifically, when being increased newly in NFV MANO system When the management entity added is NS or VNF, the corresponding management entity template of the NS or VNF newly increased specifically: network service moulding plate (Network Service Descriptor, NSD) or virtual network function template (Virtualized Network Function Descriptor, VNFD), it include the tactful metamessage description content to support required for NS, VNFD in NSD In include tactful metamessage description content to support required for VNF.Such as it will record in tactful metamessage description content The conditional attribute metamessage of management entity, management entity movement metamessage, packaging strategy when restrict condition etc., strategy Realization device executes step A2, according to tactful metamessage after getting tactful metamessage description content in management entity template Description content generation strategy metamessage, the strategy metamessage are supported required for the management entity newly increased, tactful metamessage Generating process see the prior art, details are not described herein again.

In other embodiments of the invention, step 101 obtains new when management entity increases to NFV MANO system The tactful metamessage that increased management entity needs support, can specifically include following steps:

B1, when having detected that management entity increases to NFV MANO system, obtained from tactful metamessage description template The tactful metamessage description content that management entity needs support；

B2, tactful metamessage is parsed according to tactful metamessage description content.

Wherein, in step B1, tactful realization device is detected to newly increasing management entity in NFV MANO system, When detecting the management entity newly increased, first gets the management entity and need support in which type of tactful metamessage description Hold, is determined according to tactful metamessage description content to which type of tactful metamessage management entity needs support, mentioned from publisher Carry out acquisition strategy metamessage description content in the tactful metamessage description template supplied, the tactful metamessage that publisher generates describes mould The content of plate needs to follow the regulation that NFV MANO system realizes template, and the effect of tactful metamessage description template is can to allow NFV MANO system automatically increases tactful metamessage, further, can specifically include in tactful metamessage description template as Lower step: the conditional attribute metamessage of management entity, management entity movement metamessage, packaging strategy when restrict item Part can be parsed out tactful metamessage by tactful metamessage description template.Strategy discovery device passes through tactful metamessage description Template can allow NFV MANO system automatically to increase tactful metamessage, and relevant with the tactful metamessage that these are newly increased Strategy generating.NFV MANO system provides the operation for uploading tactful metamessage description template, the strategy member letter that publisher will finish writing It ceases in content uploading NFV MANO system required for description template, is parsed by the strategy discovery device in NFV MANO system Tactful metamessage description template carries out life cycle management according to the content that the tactful metamessage description template parsed carries.

It should be noted that in previously described embodiments of the present invention, acquisition for tactful metamessage is specifically illustrated logical Crossing management entity template or tactful metamessage description template can realize, in practical applications, in NFV MANO system can be with Tactful metamessage description template is separately provided, tactful metamessage description template can also be embedded in management entity template, for example, Strategy metamessage description template is embedded in NSD/VNFD, specific implementation is without limitation.

102, tactful metamessage is sent to policy engine, so that tactful metamessage is automatically stored in policy engine, in order to Automatically from policy engine acquisition strategy metamessage and it is assembled into strategy.

In embodiments of the present invention, tactful realization device detects NFV MANO system, and to NFV MANO system Environmental change can realize adaptively, when detecting the management entity newly increased, the adaptive acquisition of tactful realization device Then the tactful metamessage needed support to the management entity newly increased will acquire tactful metamessage and be sent to strategy and draws It holds up, for policy engine under the triggering of tactful realization device sending strategy metamessage, policy engine automatically stores the plan received Slightly metamessage, client automatically from policy engine acquisition strategy metamessage and are assembled into plan under the triggering of tactful realization device Slightly.Wherein, tactful (English name Policy), strategy be executed by automatization judgement and one group of rule of policy-related (noun) come Preset terminal objective is reached, the preset terminal objective of strategy is by executing one group of relevant rule automatically come real Existing, regular (English name Rule) is the condition (English name condition) and movement (English applied to management entity Entitled action) combination, a rule is exactly for stating the setting that should be executed automatically after meeting the condition of setting Movement, rule is related to strategy, and rule is for realizing the preset terminal objective of strategy.

In embodiments of the present invention, policy engine for the assembled strategy of management client and executes the strategy, what Under the conditions of what executed act this and need user to pass through client to assemble configuration, NFV MANO system provides condition/action Deng tactful metamessage, user assembles strategy according to the requirement of oneself by client, such as provides VNF load load condition , movement includes scaleout, capacity reducing (English name scalein), some user wishes that load > 90 executes scaleout； And other user is then desirable to load > 80 and executes scaleout, condition value needs are arranged by user by client, different User require it is different, then different user will assemble different strategies by client.

It should be noted that in an embodiment of the present invention, when NFV MANO system needs to realize new function, being not required to The new function that can realize NFV MANO system is updated to policy engine, tactful realization device adaptive can obtain Get the tactful metamessage that the management entity newly increased needs support, that is to say, that strategy finds device from management entity template Or tactful metamessage is extracted in policy metadata description template, these new tactful metamessages are added in policy engine, This process is that strategy discovery device is automatically performed.Policy engine can receive the pipe newly increased from tactful realization device The tactful metamessage that reason entity needs support, the function that policy engine itself does not need to modify code again to support this new.Plan The tactful metamessage that the management entity that the acquisition that slightly realization device can be adaptive newly increases needs support, tactful realization device pair The environmental change of NFV MANO system has adaptive ability, and be capable of active gets what increased management entity needed support Tactful metamessage, policy engine also under the triggering of tactful realization device active storage strategy metamessage, client is in strategy Generation strategy under the triggering of realization device.

In some embodiments of the invention, step 101 obtains the strategy member letter that the management entity newly increased needs support After breath, strategy discovery method provided in an embodiment of the present invention can also include the following steps:

C1, the acquisition modes for obtaining the strategy execution data for needing to get when management entity is instantiated；

C2, the acquisition modes of strategy execution data are sent to data set provider, so that data set provider is held according to strategy The acquisition modes of row data get strategy execution data automatically.

Wherein, management entity it is newly-increased be added to NFV MANO system after, it is real by management that management entity, which is instantiated, For body template come what is realized, management entity also needs to get strategy execution data in instantiation, and strategy execution data are strategies Necessary data, strategy discovery device get the acquisition of strategy execution data to the strategy to come into force in engine first when being executed Mode, then the acquisition modes that data are executed to data set provider sending strategy of active, data set provider fill in strategy discovery Strategy execution data are automatically got according to the acquisition modes of strategy execution data under the triggering set.In NFV MANO system In, data set provider is for providing strategy execution data, and policy engine is according to the strategy execution data provided from data set provider Judgment rule condition meets situation, executes the movement set in the rule when meeting policy-related (noun) rule condition automatically.This In inventive embodiments data set provider strategy discovery device triggering under, according to strategy discovery device provide acquisition modes come Acquisition strategy executes data.

Be illustrated below: the policy metadata that the management entity newly increased needs support is used to assemble policing rule, The customization capability of NFV MANO system is embodied, such as: according to policy metadata: supporting { the condition userload, movement of VNF Scaluein/scaleout }, strategy can be assembled into；After strategy customization is good, trigger policy is executed with regard to needing to pass through strategy Data are executed to judge, such as: the strategy customized is if userload > 90%then scaleout, obtains different moments Strategy execution data, i.e. the value of the userload of different moments do not trigger if getting userload=80% Scaleout movement, following instant get userload value=95% item and execute, that is to say, that the different moments got Userload value is exactly strategy execution data.

It should be noted that in illustration as above, if subsequent NFV MANO system also need to increase support in addition to It can also judge to trigger scaleout by number of users usernumber (i.e. newly-increased tactful metamessage) except userload Movement just needs code of modifying to policy engine and data set provider according to the prior art, including increases usernumber Condition, and obtain different moments usernumber value (newly-increased strategy execution data), in embodiments of the present invention in order to Solution never changes the acquisition different moments that code can support the usernumber strategy metamessage newly increased and newly increase This strategy execution data of usernumber value, it is only necessary to which it is adaptive that policy enforcement means get the tactful metamessage newly increased Be sent to policy engine, get the strategy execution data newly increased acquisition modes it is adaptive data offer is provided Person, data set provider get the strategy execution data newly increased automatically.

Further, in some embodiments of the invention, abovementioned steps C1 obtains needs when management entity is instantiated The acquisition modes of the strategy execution data got, can specifically include following steps:

The corresponding management entity template of management entity is obtained, management entity template includes: to need when management entity is instantiated The acquisition modes for the strategy execution data to be got；

The acquisition modes of strategy execution data are parsed from management entity template.

Wherein, when having the management entity newly increased in NFV MANO system, it is real that management is preserved in NFV MANO system Body template, management entity template are provided by publisher, and the content format in management entity template needs to follow NFV MANO system It unites the agreement realized, includes the strategy execution data that needs are got when management entity is instantiated in management entity template Acquisition modes.Specifically, when the management entity newly increased in NFV MANO system is NS or VNF, the NS newly increased or VNF pairs The management entity template answered specifically: include the strategy execution that needs are got when NS is instantiated in NSD or VNFD, NSD The acquisition modes of data include the acquisition modes for the strategy execution data that needs are got when VNF is instantiated in VNFD.Example As recorded the location mode for the strategy execution data for thering is management entity to need support in management entity template and obtaining address, strategy Realization device parsing management physical template, so that it may therefrom get the location mode of strategy execution data and obtain address.

In other embodiments of the invention, abovementioned steps C1 obtains what needs when management entity is instantiated were got The acquisition modes of strategy execution data, can specifically include following steps:

Obtain the tactful metamessage description template, tactful metamessage description template further include: management entity is instantiated When the acquisition modes of strategy execution data that need to get；

The acquisition modes of strategy execution data are parsed from tactful metamessage description template.

Wherein, it is described in conjunction with previously described embodiments of the present invention it is found that tactful metamessage description template in the embodiment of the present invention Effect be other than automatically increasing NFV MANO system by tactful metamessage, the effect of tactful metamessage description template is also It is that the triggering of acquisition and the movement of the relevant strategy execution data of the tactful metamessage newly increased can be allowed therefore to generate Tactful metamessage description template in other than including tactful metamessage description content, also wrapped in tactful metamessage description template Include: the acquisition modes for the strategy execution data for needing to get when management entity is instantiated, strategy discovery device get plan Slightly metamessage description template, parses the acquisition modes of strategy execution data from tactful metamessage description template.
