NFVI 15 is made up of hardware resource and virtual resource and virtual level.For VNF angle, virtualization layer and hardware resource look like one and can provide the entity of required virtual resource.

In whole NFV MANO frameworks, VNFM 102 and VIM 103 quantity may be multiple, manage and safeguard respectively multiple VNF.

NFVO 101 is connected with OSS/BSS 13 by Os-Ma-Nfvo interfaces, NFVO 101 is connected with VNFM 102 by Or-Vnfm interfaces, VNFM 102 is connected with VIM 103 by Vi-Vnfm interfaces, NFVO 101 is connected with VIM 103 by Or-Vi interfaces, VNFM 102 is connected with VNF 12 by Ve-Vnfm-vnf interfaces, VNFM102 is connected with EMS/NMS 14 by Ve-Vnfm-em interfaces, and VIM 103 is connected with NFVI 15 by Nf-Vi interfaces.NFVO 101 is connected with NS Catalog 104, VNF Catalog 105, VNF Instances 106,107 4 databases of NFV Resources, and VNFM 102 is connected with database VNF Catalog 105.

In NFV, the capacity adjustment for VNF examples defines three kinds of basic mechanism, respectively adjust automatically, adjustment and pass through on demand and manage request triggering adjustment.In NFV MANO frameworks as shown in Figure 1, according to automatic adjustment mechanism, VNFM can monitor the state of each virtualization network function component (Virtualized Netw0ork Function Descriptor, VNFC) example of VNF examples and trigger capacity adjustment operation.VNFM meeting subscription base facility levels or VNF grades of event notice, wherein, basis is set The event for putting level notifies to be produced and reported by VIM, and VNF grades of event notifies to be produced and reported by VNF examples or its EMS.According to Regulation mechanism on demand, then VNF examples or its EMS monitor the VNF example states in VNF examples and trigger capacity adjustment operation, then send capacity adjust request to VNFM.According to by managing request triggering Regulation mechanism, then operated by top management system (such as OSS) or operating personnel's triggering capacity adjustment, and capacity adjust request is sent to VNFM.

Because a NS example is made up of multiple VNF examples, there is mutual contact before each VNF examples in a NS example, when the flow increase on a VNF example, the flow on same NS examples also can accordingly increase.The capacity adjustment of above-mentioned VNF examples is carried out for a VNF example, and capacity adjustment is only carried out to a VNF example, if the capacity is adjusted to dilatation, the flow on the VNF examples can be then set to increase sharply, the flow belonged to the VNF examples on other VNF examples of same NS examples will also increase, so as to cause other each VNF examples overloads；If the capacity is adjusted to capacity reducing, the flow in the VNF strength will be reduced, and the flow belonged to the VNF examples on other VNF examples of same NS examples will also be reduced, and can cause the wasting of resources of other each VNF examples.

Therefore, adjusted to optimize the capacity in NFV technologies, it is necessary to using NS as granularity, carry out unified capacity to all VNF examples in NS examples and adjust.And current NS capacity adjustment sends the request to NS progress capacity adjustment only by managing a kind of mechanism of request triggering adjustment, i.e., by OSS or operating personnel, need to indicate in request the NS is adjusted on that deployment template.That is each VNF examples of composition NS examples need the capacity carried out adjustment to be specified in the capacity adjust request that OSS or affected personnel send.

Fig. 2 is by managing the signaling process figure that request triggering NS capacity is adjusted.Illustrated in fig. 2 exemplified by carrying out dilatation to NS, as shown in Figure 2, in NFV MANO frameworks, when needing to carry out NS dilatation, first in step s 201, need to send NS dilatation request messages from triggering end to NFVO, ask NS dilatations to a new deployment template (deployment flavour).Wherein, triggering end here is typically OSS, that is, an operation manager of operator sends NS dilatation request messages manually；Triggering end can also be other authorized third party entities, such as third party Internet Service Provider.In step S202, NFVO verifies the dilatation request message, and whether the mandate including checking triggering end is legal, and verifies the correctness and the uniformity of strategy of the parameter entrained by the request.NFVO also need to by the request and NS Catalog still NSD be associated, find NSD corresponding with the request.In step S203, NFVO sends to each VNFM and checks request message, asks each VNFM to check the feasibility for the example number for indicating the VNF examples dilatation of each Self management to new template.In step In rapid S204, VNFM is checked the VNF examples of each Self management, determine VNF examples whether can dilatation to the template.In step S205, each VNFM sends inspection result to NFVO.It should be noted that step S203 to step S205 is optional step.

Then, in step S206, the dilatation demand of all VNF examples in NFVO analyses NS, it is determined that carrying out the concrete operations of dilatation to VNF examples.There are two kinds of different modes to the dilatation of VNF examples：One kind is to give the more resources of VNF example allocations (correspondence step S207), another is to instantiate a new VNF example (correspondence step S208 is usually to need to instantiate a new VNF example when the dilatation of VNF examples is to its maximum capacity).On earth which kind of processing mode should be selected to have corresponding description in VNFD.NFVO is received after NS dilatation request messages, to determine the dilatation mechanism of corresponding VNF examples, and step S207 or step S208 is performed according to the different dilatation mechanism of VNF examples, or two steps are carried out.In step S207, NFVO performs the dilatation flow of VNF examples by VNFM and VIM.In step S208, NFVO performs VNF by VNFM and VIM and instantiates flow.In step S209, the resource (such as the interference networks resource between VNF examples is provided in new deployment template) of NFVO request VIM distribution changes.In step S210, VIM distribution interconnection resources.In step S211, VIM is to NFVO feedback operation results.In step S212, NFVO sends NS dilatation confirmation messages to triggering end.

Due to that may occur the situation that flow is increased or decreased in virtual network at any time, the instruction according only to OSS or operating personnel carries out capacity adjustment to NS examples, it is impossible to tackle the changes in flow rate situation happened suddenly in NFV, and the automaticity of capacity adjustment is not high.

In addition, the NFV MANO frameworks shown in Fig. 1 are only the NFV MAMO frameworks that ETSI NVF ISG are defined at this stage.Next stage ESTI NVF ISG may proceed to define the NFV MANO frameworks of evolution.Possible NFV MANO evolution architectures have two kinds, and Fig. 3 is a kind of possible NFV MANO evolution architecture schematic diagrames, and Fig. 4 is alternatively possible NFV MANO evolution architecture schematic diagrames.

NFV MANO evolution architectures shown in Fig. 3 are compared with the NFV MANO frameworks shown in Fig. 1, its main distinction is, NFVO 101 network service composer (Network Service Orchestrator have been split into, abbreviation NSO) 301 and resource composer (Resource Orchestrator, abbreviation RO) 302.NFV MAMO evolution architectures shown in Fig. 3 are divided to providing network service capabilities and NFVI platform capabilities, the ability for effectively realizing NFVI platform resources is presented and the network service capabilities presentation after network service layout, it can effectively realize that network is serviced and platform services demand in the operator network, wherein NSO 301 is used to provide network service capacity of arranging movements, and RO 302 is used to provide NFVI moneys Source capacity of arranging movements.

NSO 301 is used to complete network service correlation function (such as network planning, network design, the network optimization).It is specific as follows：Network service requirement automatic configuration；Network service descriptor (Network Service Descriptor, abbreviation NSD) and VNF software kits (VNF package) upload management (such as new network service and program bag is uploaded)；Network service starts and network service life cycle management (run time of such as network service is set, and network service starts, updates, terminated, performance detection management, event collection etc.)；VNF instantiations are managed with reference to VNFM 102；The information (such as carrying out resource authorization confirmation or status inquiry to RO 302 or VNFM 102) of the related NFVI 15 of network service and the resources of VNF 12 is obtained to RO 302 or VNFM 102 inquiries；Integrality and legitimacy management in the network service instance execution cycle；Relation management between network service instance and VNF examples；Network service instance Topology Management；Network service instance automatic configuration is managed；Network service relevant policy information manages (such as business routing strategy, VNF 12 load balancing)；Network service failure is managed.

RO 302 is used for global resource management function, overall management distribution virtual resources.Maintenance management resource network topological diagram；The authentication vs. authorization of the resource requests of NFVI 15, these resources are likely distributed in multiple VIM 103.Distribution, reservation and the configuration of network service instance and the corresponding resource distributions of NFVI 15 of VNF examples are managed, these resources of NFVI 15 can be across one or more VIM 103；The management of VNF examples, the relation management between VNF examples and the resources of NFVI 15 for distributing to VNF examples；Policy management and network service instance and VNF examples perform management (such as resources accessing controls of NFVI 15, are reserved and/or distribution policy, configuration optimization, resource use etc.)；The resource relevant views of NFVI 15 record that VNF examples or example set are used；For example, collecting the situation for measuring the resources of NFVI 15 by the interfaces of NFVI 15, VNF examples and the usage records of NFVI 15 are then associated；The faulty resources of NFVI 15 are managed.

Meanwhile, increase such as lower interface newly：Os-Nso interfaces：OSS/BSS 13 arrives NSO 301 interface.If NSO 301 is deployed in inside OSS/BSS 13, Os-Nso interfaces are internal interface.OSS/BSS13 sends business demand, inquiry network service information (state, load etc.) etc. by Os-Nso interfaces to NSO 301；Transmission modification business demand instruction (configuration, renewal, termination etc.).NSO 301 is by Os-Nso interfaces to the feedback network business information of OSS/BSS 13.Nso-Ro interfaces：NSO 301 arrives RO 302 interface, and NSO 301 sends network configuration file, requesting query VNF 12 and/or the resource informations of NFVI 15 by Nso-Ro interfaces to RO 302；RO 302 feeds back VNF 12 and/or the fault messages of NFVI 15 by Nso-Ro interfaces to NSO 301.Os-Ro interfaces：OSS/BSS 13 arrives RO 302 interface.RO 302 is by Os-Ro interfaces to the reporting fault information of OSS/BSS 13 or NFVI 15 Resource view information.In addition, the Or-Vnfm interfaces in Fig. 1 are changed into Ro-Vnfm interfaces, the Or-Vi interfaces in Fig. 1 are changed into Ro-Vi interfaces.NSO 301 and RO 302 and NS catalogues (Catalog) 104, VNF catalogues (Catalog) 105, VNF examples (Instances) 106, NFV infrastructure devices (NFV Infrastructure, abbreviation NFVI) resource (Resources) 107 4 databases annexation are as shown in Figure 3.

Another evolution architectures of NFV MANO shown in Fig. 4 are compared with the NFV MANO evolution architectures shown in Fig. 3, and difference is, there is NSo-Vnfm interfaces between NSO 301 and VNFM 102.If there is this interface, then NSO 301 can inquire about VNF example informations etc. by VNFM 102, or send VNF instance managements instruction (such as foundation, dilatation, renewal, termination) to VNFM 102；As this interface is not present, VNF instance managements can be realized by RO 302 by VNFM 102.
