To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
The method of the embodiment of the present invention is applied in NFV systems, NFV systems have automatic editing and management (Management and Orchestration, abbreviation MAMO) function, Fig. 1 is the management of NFV systems and the configuration diagram of layout function, NFV systems include NFV composers (NFV Orchestrator, abbreviation NFVO), virtual network function manager (Virtualized Network Function Manager, abbreviation VNFM), virtualized infrastructure manager (Virtualized Infrastructure Manager, abbreviation VIM), OSS (Operation Support System, abbreviation OSS) or business support system (Business Support System, abbreviation BSS), gateway management system (Element Management System, abbreviation EMS), virtual network function (Virtualized Network Function, abbreviation VNF), network function virtualized infrastructure (Network Function Virtualization Infrastructure, abbreviation NFVI).
Wherein, NFVO realizes network service descriptor (Network Service Descriptor, abbreviation NSD), virtual network function forwarding figure (Virtualized Network Function Forwarding Graph, abbreviation VNFFG) management, network service (Network Service, abbreviation NS) life cycle management, and NFVO and VNFM coordinate the global view function of the life cycle management for realizing VNF and resource.
VNFM realizes VNF life cycle management, including virtualization network function descriptor (Virtualized Infrastructure Manager, abbreviation VNFD) management, the establishment of VNF examples, VNF dilatation/capacity reducing, the termination of VNF examples, supports to receive elastic telescopic (scaling) strategy that NFVO is issued, realizes VNF elastic telescopic.
OSS/BSS is main to be made up of the part such as network management, system administration, charging, business, account and customer service, between system by unified bus organic combination together.
EMS performs traditional fault management, configuration management, accounting management, performance management, safety management (Fault Management for VNF, Configuration Management, Accounting Management, Performance Management, Security Management, abbreviation FCAPS) function.
Physical network function (the Physical Network Function that VNF corresponds in traditional non-virtualized network, abbreviation PNF), such as evolution block core net (Evolved Packet Core, abbreviation EPC) node of virtualization, the EPC nodes of virtualization include：Mobile management entity (Mobile Management Entity, abbreviation MME), gateway (Serving GateWay, abbreviation SGW) and packet data gateway (Packet Data Network GateWay, abbreviation PGW) etc..Wherein, whether the function sexual behavior and state of network virtualize unrelated with network, and VNF and PNF possess identical function sexual behavior and external interface in NFV systems.VNF can be made up of the other component of multiple even lower levels, therefore, and a VNF can be deployed on multiple virtual machines (Virtualized Machine, abbreviation VM), and each VM carries a VNF component.VNF can also be deployed on a VM.NFVI is made up of hardware resource and virtual resource and virtual level, for VNF angle, and virtualization layer and hardware resource look like one and can provide the entity of required virtual resource.
MANO data are all stored in following four repository：Network catalogue (NS Catalog)：Including all NSD loaded.Virtual network function catalogue (VNF Catalog)：Including all VNF Packages loaded.Network function virtualization example (NFV Instances)：Including all NS examples and VNF examples being currently running.Network function virtualized infrastructure resource (NFVI Resources), includes the state of all NFVI resources, for example, available/reserved/allocated NFVI resources.
MANO functions can apply the management based on strategy.For example：In NS life cycle management, OSS/BSS configures automatic dilatation/capacity reducing strategy of NS examples by Os-Nfvo interfaces to NFVO.The automatic dilatation/capacity reducing strategy indicates that NFVO performs NS dilatation/capacity reducing operation automatically under given conditions.For example, when the NFVO NS monitored performance indications " calls (Calls-per-second) per second " are more than a thresholding pre-set, NFVO moves to the NS examples from the template (Deployment Flavor) 1 of deployment the template 2 of deployment, and the difference of wherein template 1 and template 2 is to have carried out dilatation operation to one of VNF.
Similarly, in VNF life cycle management, NFVO again may be by automatic dilatation/capacity reducing strategy that Nfvo-Vnfm interfaces configure VNF examples to VNFM, indicates that VNFM performs VNF dilatation/capacity reducing operation automatically under given conditions, increases or decreases VNF virtual resource.In addition, can also configure the strategy of some other life cycle management in NFV Orchestrator or VNF Manager, such as：To tactful, load balancing of VNF examples etc. from the healing certainly for curing functional configuration of Network example.Multiple strategies can form latent when being performed in identical functional entity
Execution conflict.For example, two strategies configured in NFVO, one of them is when monitoring that the calls per second of NS examples reaches a thresholding, it is determined that implementing dilatation operation to the VNF-A for constituting NS examples；And another policy mandates NFVO monitors the VNFFG of NS examples, as certain virtual link (the Virtual Link in VNFFG, abbreviation VL) obstruction when, NFVO reduces execution priority to the end points (VNF) of the virtual link, the virtual resource of the end points is transferred to other use out and used to others VNF, and VNF-A is an end points of the virtual link, capacity reducing operation is correspondingly performed.Two strategies are generated under different conditions performs the operation of two effects of dilatation/capacity reducing conversely to same VNF-A, so as to form strategy execution conflict.
In order to solve problem of the prior art, the embodiment of the present invention one provides the strategy coordination method in a kind of NFV systems, the flow chart of strategy coordination method in the NFV systems that Fig. 2 provides for the embodiment of the present invention one, as shown in Fig. 2 the method that the present embodiment is provided may comprise steps of：
Step 101, policy execution entity obtain priority of each strategy under policy co-ordination dimension in M strategy, and M strategy, and each strategy includes：Policy condition and action is performed, the policy co-ordination dimension of m-th of strategy in M strategy includes at least one in following information：M-th strategy, the execution of m-th of strategy are acted or m-th of tactful optimization aim, and the optimization aim of m-th of strategy is the optimization aim in the policy condition of m-th of strategy, and M is the integer more than or equal to 2, and m value is 1,2 ... ..., M.
In the present embodiment, policy decision entity can for OSS/BSS or other there is the equipment of strategy decisive function.Policy execution entity can be VNFVO or VNFM.
For each strategy, if the policy co-ordination dimension of m-th of strategy is m-th of strategy itself, policy execution entity obtains the priority that the policy co-ordination dimension is directed in M strategy, and M strategy, is specially：Policy execution entity receives the M strategy that policy decision entity is sent, and each tactful priority, wherein, the priority of M strategy is not mutually different.The priority of each strategy is set by policy decision entity and is handed down to policy execution entity.
In the present embodiment, each strategy can perform action (action) including one or more, when the strategy meets different policy conditions, different actions are performed, " for the composition object (such as VNF) of same monitoring; if meeting condition A; then perform action, if meeting condition B, execution acts 2 for example, a NS strategy is expressed as.For this strategy acted with multiple execution, policy decision entity in each strategy for be handed down to policy execution entity in addition to the execution priority for being equipped with determination, also increase it is corresponding perform action, i.e., priority and tactful execution are acted and tied up
It is fixed.
For each strategy, if the policy co-ordination dimension of m-th of strategy performs action for m-th of the multiple of strategy, policy execution entity obtains priority of each strategy under the policy co-ordination dimension in M strategy, and M strategy, is specially：Policy execution entity receives the M strategy that policy decision entity is sent, and the priority of each execution action of each strategy, wherein, the priority of execution action between M strategy is different, still, and the priority of same tactful multiple execution action is identical, each policy condition being primarily due in same strategy can not possibly be while meet, therefore, execution action can not possibly be performed simultaneously, and can only perform every time in multiple execution actions one performs action.
For each strategy, if the policy co-ordination dimension of m-th of strategy is the optimization aim of m-th of strategy, policy execution entity obtains priority of each strategy under the policy co-ordination dimension in M strategy, and M strategy, is specially：First, policy execution entity receives the priority for N number of optimization aim that policy decision entity is sent, and N is the integer more than or equal to 1, and the priority of N number of optimization aim is different；Then, policy execution entity receives the M strategy that policy decision entity is sent, and each tactful optimization aim is obtained from each strategy；Finally, for each strategy, policy execution entity determines the priority of the optimization aim of m-th of strategy according to the optimization aim of m-th of strategy and the priority of N number of optimization aim.
Wherein, N number of optimization aim includes any one in following Network parameter or its combination：The business loads of NS examples, the energy consumption of NS examples, the VNFFG of NS examples business Route Selection, the virtual network function VNF failures of the VNFFG of NS examples service link congestion or NS examples.Policy execution entity can determine the priority of optimization aim according to NS example deployments demand, portfolio scale or QoS demand, and the priority of optimization aim is handed down into policy execution entity.Subsequently, during strategy is created, policy decision entity is only needed policy distribution to policy execution entity, policy execution entity obtains the tactful optimization aim from the strategy received, the priority for the optimization aim that policy execution entity is issued according to policy decision entity, obtains the priority of the optimization aim to strategy.In the present embodiment, the priority of optimization aim can also be pre-configured with policy execution entity, rather than be issued by policy decision entity.
Pass through foregoing description, when policy co-ordination dimension acts for the execution in strategy itself or strategy, priority of the strategy under the policy co-ordination dimension is bound with strategy, when policy co-ordination dimension is optimization aim, priority of the strategy under the policy co-ordination dimension not with strategy binding, only with it is excellent
The significance level for changing target execution is relevant.
Step 102, when M strategy in first strategy execution action with M strategy in second strategy execution act clash when, policy execution entity determines that target performs action according to the priority of priority and the second strategy under the policy co-ordination dimension of first strategy under the policy co-ordination dimension, and performance objective performs action.
Specifically, policy execution entity compares priority and second strategy priority under the policy co-ordination dimension of first strategy under the policy co-ordination dimension；If priority of first priority of the strategy under the policy co-ordination dimension higher than the second strategy under the policy co-ordination dimension, policy execution entity determines that the execution action of the first strategy performs action for target, and performs first and tactful perform action；If the first strategy the policy co-ordination dimension priority less than the second priority of the strategy under the policy co-ordination dimension, policy execution entity determines that the execution action of the second strategy performs action for target, and performs second and tactful perform action.
Optionally, policy execution entity is also reported because performing the strategy that conflict is not performed to policy decision entity.So that policy decision entity adjusts each priority of the strategy under the policy co-ordination dimension according to the priority of the tactful policy co-ordination dimension not being performed.
In the present embodiment, the policy co-ordination dimension that policy execution entity obtains m-th of strategy in M strategy, and each priority of the policy co-ordination dimension of strategy, M strategy includes at least one in following information：M-th strategy, the execution of m-th of strategy are acted or m-th of tactful optimization aim, when the execution action and the execution action of the second strategy in M strategy of the first strategy in M strategy are clashed, policy execution entity determines that target performs action according to the priority of priority and the second strategy under the policy co-ordination dimension of first strategy under the policy co-ordination dimension, and performance objective performs action.In methods described, by setting priority for each tactful policy co-ordination dimension, when two strategies are clashed, according to the policy co-ordination dimension priority of strategy height, implementation strategy coordinates the high strategy of priority of dimension, it is to avoid tactful execution conflict can cause to be expected inconsistent implementation effect with policy development person.
The flow chart of strategy coordination method in the NFV systems that Fig. 3 provides for the embodiment of the present invention two, the present embodiment is described from the angle of policy decision entity, as shown in figure 3, the method that the present embodiment is provided may comprise steps of：
Step 201, policy decision entity formulate each strategy in priority, M strategy for the policy co-ordination dimension of M strategy to be included：Policy condition and action is performed, m-th of plan in M strategy
Policy co-ordination dimension slightly includes at least one in following information：M-th strategy, the execution of m-th of strategy are acted or m-th of tactful optimization aim, and the optimization aim of m-th of strategy is the optimization aim in the policy condition of m-th of strategy, and M is the integer more than or equal to 2, and m value is 1,2 ... ..., M.
Policy decision entity for the policy co-ordination dimension of M strategy when formulating priority, can be according to policy co-ordination dimension setting priority of the importance of strategy for M strategy, set priority that high priority is set for the high tactful policy co-ordination dimension of importance, priority is formulated for the low tactful policy co-ordination dimension of importance, and low priority is set, to ensure that the high strategy of importance can be performed when two strategies are clashed.When policy co-ordination dimension is optimization aim, policy execution entity can be that optimization aim sets priority according to NS example deployments demand, portfolio scale or QoS demand.
M strategy, and the priority of the policy co-ordination dimension of M strategy are sent to policy execution entity by step 202, policy decision entity.
In the present embodiment, policy decision entity passes through the priority for each strategy setting under policy co-ordination dimension, and priority of each strategy under the policy co-ordination dimension is handed down to policy execution entity, with policy execution entity when two strategies are clashed, according to priority height of the strategy under the policy co-ordination dimension, implementation strategy coordinates the high strategy of priority of dimension, it is to avoid tactful execution conflict can cause to be expected inconsistent implementation effect with policy development person.
The scheme of embodiment one will be described in detail by specific embodiment below, the flow chart of strategy coordination method in the NFV systems that Fig. 4 provides for the embodiment of the present invention three, illustrated in the present embodiment so that policy co-ordination dimension is strategy itself as an example, as shown in figure 4, the method that the present embodiment is provided may comprise steps of：
Step 301, policy decision entity send priority, the priority of automatic dilatation/capacity reducing strategy 2 of automatic dilatation/capacity reducing strategy 1 (auto-scale-policy) in NSD restockings (on-boarding) stage to policy execution entity.
NS establishment includes two stages：NSD on-boarding stages and establishment NS example (create NS instance) stages, different strategies may be issued in two stage policy decision entities, and be the different priority of different strategy settings.The priority for automatic dilatation/capacity reducing strategy that policy decision entity is issued can be represented in the following way：NS on-boarding((auto-scale-policy1,priority-x1),(auto-scale-policy2,priority-x2)).
Step 302, policy decision entity are creating priority of the NS example stages to strategy 2 when strategy (runtime-policy-Info) 1 priority, operation during policy execution entity transmission operation.
The priority of strategy can be represented in the following way during the operation that policy decision entity is issued：create NS instance((runtime-policy-Info1,priority-y1),(runtime-policy-Info2,priority-y2)).
Step 303, policy execution entity inspection policies perform conflict, and target strategy, performance objective strategy are determined according to two tactful priority for occurring strategy execution conflict.
