Wherein, NS instantiations request is for indicating the member that is needed in the NS and the composition NS The VL examples for needing, due to introducing the concept of VNS in NVF systems, therefore, this When NS need member can specifically include VNS examples and/or VNF examples, the VNS examples And/or the number of VNF examples is unrestricted, so, NFVO just can be in subsequent step 102-110 The middle member needed according to NS and a VL examples, for the NS distributes corresponding resource, most NS examples are set up eventually, to complete the NS instantiation operations.

Exemplary, NS instantiation requests can carry the mark and specification information (example of NSD Such as Flavor-ID) mark, wherein, the mark of the NSD for indicate to need in the NS into The type of member, it is VNF that the mark of such as NSD may be used to indicate the member needed in current NS Example 1 and VNS examples 2；And the mark of the specification information is used to indicate the attribute of the NS, and The attribute of the member needed in the NS, for example, the amount of capacity of current NS, VNF examples 1 Telephone traffic size of number and VNS examples 2 etc..The design parameter of the attribute can be according to NFVO In content in the deployment template that prestores be defined, the embodiment of the present invention does not make any limit to this System.Therefore, it can determine NS according to the mark of the NSD and the mark of the NS specification informations The type of the member of middle needs and the attribute of member, i.e., specifically indicate the VNS needed in the NS Example.

Further, NFVO can determine that the NSD, Jin Ergen of the NS according to the mark of the NSD Determine at least one in VNFD, VNSD, VLD in the NS according to the NSD；Also, root The corresponding specification informations of VNFD, the corresponding specification informations of VNSD are further determined that according to the specification information At least one in specification information corresponding with VLD.

Also, NFVO can also determine the VNFFGD in the NS according to the NSD, should VNFFGD is used to describe the VNFFG of the NS, i.e. the VNFFGD is used to may be used to indicate this The VL examples that NS needs, can include one or more VNFFG in a NS example, That is multiple VNFFGD be may include in the NSD.If NS examples include multiple VNFFG, that , for each VNFFG, NFVO is repeatable to perform above-mentioned steps 103-110, finally builds The plurality of VNFFG in vertical NS examples.

The schematic diagram of VNFFG shown in Figure 3, NFVO is according at least one for determining VNFFG, just may further determine that out in the NS examples in each VNFFG, each VNS Annexation between example or VNF examples.

Step 102 is optional step, and in a step 102, NFVO checks NS instantiation requests Validity.For example, check the NS instantiation request sender whether be authorized to etc..Wherein, If current NS includes multiple VNFFG and policing rule, perhaps policing rule can cause to only have Part VNFFG is effective for the NS.

In step 103a, if the member that instruction NS needs in NS instantiation requests includes VNS Example, then NFVO the VNS examples are searched from VNSM and be whether there is.

Specifically, according in step 101 NS instantiation request in carry NSD mark and Whether the mark of specification information, NFVO includes VNS examples in can further determining that the NS examples, If including VNS examples, performing step 103a, i.e., NS is determined according to NS instantiation requests The VNS example lists for needing are instantiated, the VNS lists include at least one VNS examples； And then, NFVO can be communicated with VNSM, be determined from the example record information of VNSM VNS examples in VNS example lists whether there is, wherein, the VNS that VNSM will can have been instantiated Example carries out record and generates the example record information.So, NFVO just can be looked into from VNSM The VNS examples are looked for whether there is.

In step 103b, if the member that instruction NS needs in NS instantiation requests includes VNF Example, then NFVO the VNF examples are searched from VNFM and be whether there is.

It is similar, mark according to the NSD carried in NS instantiations request in step 101 and The mark of specification information, book is no including VNF examples during NFVO can further determine that the NS examples, If including VNF examples, performing step 103b, i.e., NS is determined according to NS instantiation requests The VNF example lists for needing are instantiated, the VNF lists include at least one VNF examples； And then, NFVO can be communicated with VNFM, be determined from the example record information of VNFM VNF examples in VNF example lists whether there is.

Step 104 is optional step, and at step 104, NFVO can be communicated with VIM, Whether the Internet resources that request VIM checks VNF examples and/or the interconnection of VNS examples and needs can use, And the resource is reserved.

For example, NFVO can generate resource-reservation operations by virtual resource management interface, and then, NFVO sends to VIM and asks, and request VIM checks that VNF examples and/or the interconnection of VNS examples are needed Whether the Internet resources wanted be can use, and these resources are reserved.VIM is checked after receiving the request The availability of the Internet resources that VNF examples and/or the interconnection of VNS examples need, and complete predetermined, enter And the result of resource reservation is returned to NFVO.

In step 105, illustrated in a step 101, by NS instantiation requests institute The mark of VNFFGD in the NS is carried in the NSD of instruction, and the VLD can be used to describe First VL examples, therefore, NFVO determines constituting the NS need according to NS instantiation requests The VL examples wanted, and then, NFVO can send VL instantiation requests, request to VIM The VIM performs VL instantiation operations, and VIM performs VL realities after receiving VL instantiation requests Exampleization is operated, and obtains a VL examples of NS needs.

It should be noted that because one or more VL in the NS examples may have been carried out Instantiation operation, therefore, that is, the VL examples having may be present, therefore, NFVO is only Needs are extended on existing VL examples.

In step 106a, if the VNS examples do not exist in step 103a, NFVO is performed VNS instantiation operations, obtain the VNS examples.

Specifically, in step 103a, NFVO determines NS realities according to NS instantiation requests The VNS example lists that exampleization needs, and search the VNS examples and whether there is, due to VNS realities VNS examples in example list may have multiple, therefore, in step 107a, for VNS realities Non-existent VNS examples in example list, the executable VNS instantiation operations of NFVO, until VNS VNS examples in example list are all instantiated.

Wherein, NFVO can send VNS instantiation requests to VNSM, to cause VNSM roots VNS instantiation operations please be perform according to VNS instantiations, the VNSM performs VNS instantiation behaviour The method of work will be elaborated in subsequent embodiment, therefore here is omitted.

In implementing, as a kind of feasible way of example, when NFVO and VNSM collection During into same entity device, NFVO itself can determine the VNF realities needed in the VNS The 2nd VL examples that example and composition VNS examples need；Now, NFVO is according to need in VNS The VNF examples wanted, perform VNF instantiation operations, to obtain the VNF examples；Also, root According to the 2nd VL examples that composition VNS examples need, VL instantiation operations are performed, to be somebody's turn to do 2nd VL examples；Finally, NFVO to VIM send the second connection request, with cause VIM according to The connection that second connection request is set up between VNF examples and the 2nd VL examples, to complete the VNS Instantiation operation.

Similar, in step 106b, if the VNF examples do not exist in step 103b, NFVO performs VNF instantiation operations, obtains the VNF examples.Wherein, NFVO performs VNF Instantiation operation is identical with the process that VNF in the prior art is instantiated, so be in not repeating.

By step 101-106, can obtain in NS examples required all in a VNFFG VNF examples, VNS examples and VNL examples are (assuming that include VNF examples simultaneously in NS examples With VNS examples), therefore, in step 107, NFVO is communicated with VIM, to VIM The first connection request is sent, the VNS examples and/or step for asking the VIM to be obtained in step 106a The VNF examples obtained in rapid 106b are set up with the VL examples obtained in step 105 and are connected.

Optionally, in step 108, NFVO can indicate NM (Network Manager, Management node) external interface of VNF examples and/or VNS examples is connected to physical network work( On energy interface.Wherein, NM can be OSS, NMS, EM or WIM.

Finally, in step 109, NFVO can set up the transmitting terminal (example of the NS examples to request Such as, OSS) NS instantiation operation completion messages are sent, to confirm that the NS instantiation operations are completed, Set up the NS examples.

Wherein, the execution step of NFVO is related in above-mentioned steps 101-109, can be by NFVO The programmed instruction stored in computing device memory in above-mentioned Fig. 5 is realized.

So far, embodiments of the invention provide a kind of method of NS instantiations, are applied to introduce VNS The NVF systems of concept, wherein, NFVO obtains the NS instantiation requests of NS, the NS examples Change request for indicating the VNS examples and a VL examples that are needed in the NS；If the NS realities The member of the NS is indicated in exampleization request includes VNS examples, and NFVO is searched from VNSM should VNS examples whether there is；If the VNS examples do not exist, NFVO performs VNS instantiations Operation, obtains the VNS examples；Finally, VNS examples are set up with a VL examples and are connected, To set up NS examples.So, in this NFV systems, NFVO can be with VNS examples One unit carries out NS instantiations, that is to say, that NFVO need to only set up the VNS needed in NS First VL examples of example and composition NS needs, and without to the VNF in VNS examples Example and the 2nd VL examples are scheduled, so as to reduce NFVO answering in operation and maintenance process Miscellaneous degree, improves dispatching efficiency.

Based on the NFV systems shown in Fig. 2, embodiments of the invention provide a kind of expansion of NS examples Appearance method, as shown in fig. 7, the method includes：

201st, NFVO receives the dilatation request of the NS examples that OSS sends, and is taken in dilatation request Mark with the specification information more than current NS capacity.

202nd, (optional) NFVO checks the validity of dilatation request.

203rd, NFVO is according to the mark of the specification information, and the indicated NSD of dilatation request, Determine expansion plan.

If 204a, the expansion plan include VNS example dilatations, NFVO enters with VNSM Row communication, dilatation operation is performed to the VNS examples.

If 204b, the expansion plan include VNS instantiation operations, NFVO enters with VNSM Row communication, performs VNS instantiation operations, to set up new VNS examples.

If 204c, the expansion plan include VNF example dilatations, NFVO and VNFM is carried out Communication, dilatation operation is performed to the VNF examples.

If 204d, the expansion plan include VNF instantiation operations, NFVO enters with VNFM Row communication, performs VNF instantiation operations, to set up new VNF examples.

205th, NFVO sends to VIM and updates request, and VIM is in the NS examples after dilatation for request A VL examples be updated.

206th, NFVO sends NS examples dilatation operation completion message to OSS.

In step 201, NFVO obtains the dilatation request of NS examples, for example, being connect from 0SS The dilatation request for the NS examples is received, wherein, carried more than current NS in dilatation request The mark of the specification information of capacity.Further, for instruction NFVO is carried out to which NS example Dilatation is operated, and the mark of the NS examples can also be carried in dilatation request.

Specifically, NSD can include multiple specification informations (for example, deployment template flavours), Each deployment template has a resource requirement of oneself, such as VNF instance numbers, VNS instance numbers and Network connection etc., it is exemplary, it is assumed that in the NSD that NFVO is used when the NS examples are set up Deployment template be：VoLTE_NSD_300W_service_deployment_flavor deployment, And dilatation to VoLTE_NSD_500W_service_deployment_flavor is needed now, that , can be carried in dilatation request The mark of the specification information corresponding to VoLTE_NSD_500W_service_deployment_flavor Know.

It is similar with the expansion method described in above-mentioned steps 201-206, based on the NFV shown in Fig. 2 System, embodiments of the invention provide the capacity reduction method of another kind NS examples.

Wherein, similar with step 201, when the operation of NS capacity reducings is carried out, NFVO obtains NS The capacity reducing request of example, carries the mark of the specification information less than current NS capacity in capacity reducing request Know.

Optionally, in step 202., NFVO checks the validity of dilatation request, for example, inspection Look into the NS instantiation request sender whether be authorized to etc..

Similar with step 201, when the operation of NS capacity reducings is carried out, NFVO can also check the contracting Hold the validity of request.

In step 203, the mark of the specification information carried during NFVO is asked according to the dilatation, really Determine the NSD corresponding to the NS after dilatation, and then according to the NSD and the mark of the specification information It is determined that specific expansion plan.

Due to one NS example of dilatation be by dilatation constitute the NS examples VNF examples and/or VNS examples are realized, and to realize a VNF example and/or the dilatation of VNS examples include two The mode of kind, as the VNF examples and/or the more resources of VNS example applications or directly newly-generated One VNF example and/or VNS examples.

Therefore, the expansion plan of a NS example specifically includes following possibility：1st, when in NS examples VNS examples when needing dilatation, dilatation (as VNS realities can be carried out to the VNS examples The more resources of example application) or a VNS example is re-established to meet the capacity need after dilatation Ask；2nd, when the VNF examples in NS examples need dilatation, the VNF examples can be carried out Dilatation (the as more resources of VNF example applications) or re-establish a VNF example with Meet the capacity requirement after dilatation.

And then, in 204a, if the expansion plan includes the dilatation operation of VNS examples, NFVO Communicated with VNSM, dilatation operation is performed to the VNS examples.

It is if the expansion plan includes VNS instantiation operations, i.e., newly-built one in step 204b Meet the VNS examples of capacity requirement after dilatation, then NFVO is communicated with VNSM, perform VNS instantiation operations, set up new VNS examples.

Wherein, the method for VNS instantiations and the expansion method of VNS examples will be in subsequent embodiments In be discussed in detail, therefore here is omitted.

In step 204c, if the expansion plan includes the dilatation operation of VNF examples, NFVO Communicated with VNFM, dilatation operation is performed to the VNF examples.

It is if the expansion plan includes VNF instantiation operations, i.e., newly-built one in step 204d Meet the VNF examples of capacity requirement after dilatation, then NFVO is communicated with VNFM, perform VNF instantiation operations, set up new VNF examples.

Wherein, VNF instantiation method and VNF examples expansion method similarly to the prior art, Therefore here is omitted.

Further, in step 205, after above-mentioned expansion plan is performed, the VNF in NS examples Annexation between example and/or VNS examples it may happen that change, for example, the VNF before dilatation Example 1 is connected with VNS examples 1 by VL1, but performs the dilatation in above-mentioned steps 204b After plan, the new preoperative VNS examples 1 of substitution dilatation of VNS examples 2 are established, therefore, NFVO needs to be sent to VIM and updates request, and request VIM is to the in the NS examples after dilatation One VL examples are updated, after VIM receives renewal request, to the VL in NS examples Example is updated, for example, be connected VNF examples 2 by VL1 with VNS examples 1.

Finally, in step 206, the hair that NFVO can be asked to the dilatation for sending the NS examples Sending end (for example, OSS) sends NS examples dilatation operation completion message, to confirm the NS examples Dilatation operation complete.

Wherein, the step of being related to NFVO to perform in step 201-206, can by NFVO according to The programmed instruction stored in computing device memory in above-mentioned Fig. 5 is realized.

Similar with above-mentioned dilatation operation, one NS example of capacity reducing is to constitute the NS realities by capacity reducing The VNF examples and/or VNS examples of example is realized, and realizes a VNF example and/or VNS The capacity reducing of example includes two ways, that is, reduce the VNF examples and/or the VNS examples resource or Directly terminate the VNF examples and/or VNS examples.

Therefore, the capacity reducing plan of a NS example specifically includes following possibility：1st, when in NS examples VNS examples when needing capacity reducing, capacity reducing can be carried out to the VNS examples and (reduce the VNS The resource of example) or terminate the VNS examples to meet the capacity requirement after capacity reducing；2nd, NS is worked as When VNF examples in example need capacity reducing, capacity reducing can be carried out to the VNF examples, and (reducing should The resource of VNF examples) or terminate the VNF examples to meet the capacity requirement after capacity reducing.

Further, if the capacity reducing includes VNS example capacity reducings in the works, NFVO is to the VNS Example performs capacity reducing operation；If the capacity reducing includes that VNS examples terminate operation, NFVO in the works Perform VNS examples and terminate operation, wherein, the capacity reduction method of VNS examples and the end of VNS examples Only method will be elaborated in subsequent embodiment, therefore here is omitted.If the capacity reducing is wrapped in the works VNF example capacity reducings are included, then NFVO performs capacity reducing operation to the VNF examples；If the capacity reducing plan Include that VNF examples terminate operation, then NFVO performs VNF examples and terminates operating.

It is similar with above-mentioned dilatation operation, after above-mentioned capacity reducing plan is performed, the VNF in NS examples Annexation between example and/or VNS examples it may happen that change, therefore, NFVO needs Sent to VIM and asked, request VIM is updated to the VL examples in the NS examples after capacity reducing, It is finally completed NS capacity reducings operation.

So far, embodiments of the invention provide a kind of transfiguration method of NS examples (i.e. dilatation operation or Capacity reducing is operated), it is applied to introduce the NVF systems of VNS concepts, NFVO can be with VNS realities Example performs the dilatation operation or capacity reducing operation of NS examples for a unit, without in VNS examples VNF examples carry out dilatation operation or capacity reducing operation, so as to reducing NFVO and run and safeguard Complexity in journey, improves dispatching efficiency.

Based on the NFV systems shown in Fig. 2, embodiments of the invention provide a kind of end of NS examples Only method.

Specifically, NFVO can obtain the termination request of NS examples, carried in termination request The mark of the NS examples.If the NS examples include VNS examples, NFVO is to VNSM Request terminates the VNS examples that NS examples include；If the NS examples include VNF examples, Then NFVO terminates the VNF examples that NS examples include to VNFM requests.And then, NFVO The VL examples in the NS examples between member are deleted to VIM requests.

It should be noted that when terminating a NS example, it is understood that there may be one or more of may： A, before NS instantiations are carried out to the NS, some VNF examples and/or VNS examples have been deposited Can not then deleted in these VNF examples of step and/or VNS examples.In b, the NS examples All VNF examples and/or VNS examples, be all the NS instantiate when generate, then, this A little VNF examples and/or VNS examples will terminate, these VNF examples and/or VNS examples it Between annexation (such as VL) also to delete.At least one VNF in c, the NS examples Example and/or VNS examples are used for others NS examples simultaneously, now, retain others NS realities Between the VNF examples and/or VNS examples and these VNF examples and/or VNS examples of example needs Network connection, while terminating VNF examples and/or VNS that those other NS examples are not used Annexation between example, and these VNF examples and/or VNS examples.

So far, embodiments of the invention provide a kind of terminating method of NS examples, are applied to introduce VNS The NVF systems of concept, NFVO can be an end for unit execution NS examples with VNS examples Only operate, without carrying out terminating operation or capacity reducing operation to the VNF examples in VNS examples, so that Complexities of the NFVO in operation and maintenance process is reduced, dispatching efficiency is improved.

Based on the NFV systems shown in Fig. 2, embodiments of the invention provide a kind of liter of NS examples Level method, as shown in figure 8, the method includes：

301st, NFVO receives the upgrade request of the NS examples that OSS sends, and the upgrade request includes The mark of the mark of VNSD to be upgraded and the VNSD for upgrading.

Wherein, the upgrade request can also include the mark of VNFD to be upgraded and for upgrading VNFD mark.

Further, to indicate NFVO carries out updating operation to which NS example, the upgrading please The mark of the NS examples can also be carried in asking.

Optionally, can also be carried in the upgrade request carries out the VNFD that upgrade request operation is relied on And/or VNSD marks and demand (demand can be version information, resource information etc.).

302nd, (optional) NFVO checks the validity of the upgrade request.

303a, NFVO determine to need the of instantiation according to the mark of VNSD for being used to upgrade One VNS lists, and the 2nd VNS for determining to need to terminate according to the mark of VNSD to be upgraded List.

Specifically, NFVO carries out resource and dependence inspection according to the mark of the VNSD for being used for upgrading Look into, it is determined that a VNS lists (needing the VNS examples for re-establishing) of instantiation are needed, And determine the 2nd VNS lists (needing the VNS examples being terminated) for needing to terminate, so, NFVO just can be by VNS examples the 2nd VNS lists of replacement new in a VNS lists VNS examples, so as to complete the updating operation of NS examples.

303b, NFVO determine to need the of instantiation according to the mark of VNFD for being used to upgrade One VNF lists, and the 2nd VNF row for determining to need to terminate according to the mark of VNFD to be upgraded Table.

304a, NFVO are communicated according to a VNS lists with VNSM, perform VNS realities Exampleization is operated, the VNS examples after being upgraded.

Wherein, the method for VNS instantiations will be elaborated in subsequent embodiment, therefore no longer be gone to live in the household of one's in-laws on getting married herein State.

304b, NFVO are communicated according to a VNF lists with VNFM, perform VNF realities Exampleization is operated, the VNF examples after being upgraded.

305th, NFVO sends to VIM and updates request, and request VIM updates the in the NS examples One VL examples, to complete the upgrading of NS examples.

Specifically, because NFVO replaces in former 2nd VNS lists the VNS examples after upgrading VNS examples, and/or, the VNF examples after upgrading are replaced into the VNF in former 2nd VNF lists Example, therefore, the annexation in the NS examples changes, therefore, NFVO needs to update A VL examples in the NS examples between member, obtain new VNFFG.

306a, NFVO are communicated with VNSM, terminate the VNS realities in the 2nd VNS lists Example.

Wherein, the method that VNS examples terminate will be elaborated in subsequent embodiment, therefore herein no longer Repeat.

306b, NFVO are communicated with VNFM, terminate the VNF realities in the 2nd VNF lists Example.

It should be noted that the present invention not holding between conditioning step 505 and step 506a-506b Row order.

And then, in step 307, NFVO sends NS examples updating operation and completes to disappear to OSS Breath, is completed with the updating operation for confirming the NS examples.

Wherein, the step of being related to NFVO to perform in step 301-307, can by NFVO according to The programmed instruction stored in computing device memory in above-mentioned Fig. 5 is realized.

So far, embodiments of the invention provide a kind of upgrade method of NS examples, are applied to introduce VNS The NVF systems of concept, NFVO can be a liter for unit execution NS examples with VNS examples Level operation, without carrying out updating operation or capacity reducing operation to the VNF examples in VNS examples, so that Complexities of the NFVO in operation and maintenance process is reduced, dispatching efficiency is improved.

Based on the NFV systems shown in Fig. 2, embodiments of the invention provide a kind of VNS instantiations Method, as shown in figure 9, the method includes：

401st, VNSM receives the VNS instantiation requests of the VNS that NFVO sends, the VNS Instantiation request is used for the VNF examples and composition VNS examples need for indicating to be needed in the VNS The VL examples wanted.

402nd, (optional) VNSM checks the validity of VNS instantiation requests.

403rd, the VNF examples that VNSM is searched in the VNS whether there is.

404th, VNSM is instantiated according to the VNS and asked, and VL instantiation requests are sent to VIM, To cause that VIM performs VL instantiation operations after receiving VL instantiation requests, VNF realities are obtained The 2nd VL examples between example.

If the 405, the VNF examples do not exist in step 403, VNSM performs VNF instantiations Operation, obtains the VNF examples.

406th, VNSM sends connection request to VIM, to cause that VIM will be obtained in step 405 VNF examples set up with the 2nd VL examples that are obtained in step 404 and be connected.

407th, VNSM sends VNS instantiation operation completion messages to NFVO, to confirm the VNS Instantiation operation is completed, and sets up the VNS examples.

In step 401, VNSM obtains the VNS instantiation requests of VNS, for example, from NFVO The VNS received for the VNS instantiates request.

Specifically, reference can be made in the embodiment of above-mentioned NS examples, in above-mentioned steps 106a, when When NFVO needs to perform VNS instantiations, VNS instantiation requests can be sent to VNSM, with So that VNSM performs following step 402-407, to set up the VNS examples.

Wherein, VNS instantiations request for indicate the VNF examples that are needed in the VNS and Constitute the 2nd VL examples of VNS examples needs.

For example, VNS instantiation requests can carry the mark of VNSD and the mark of specification information Know, wherein, the mark of the VNSD is used to indicate the type of VNF examples in the VNS；And the rule The mark of lattice information is used to indicate the attribute of the VNF examples, and VNF realities in the VNF examples The attribute of example, for example, amount of capacity, number of VNF examples 1 of current VNS etc..

Also, VNSM can also determine the VNFFGD in the VNS according to the VNSD, should VNFFGD is used to describe the VNFFG of the VNS, that is, constitute the second of VNS examples needs VL examples, can be including in one or more VNFFG, the i.e. VNSD in a VNS example May include multiple VNFFGD.If VNS examples include multiple VNFFG, then, for every One VNFFG, NFVO are repeatable to perform above-mentioned steps 403-407, finally sets up VNS examples In the plurality of VNFFG.

The schematic diagram of VNFFG shown in Figure 4, VNSM is determined to this according to VNFFGD The corresponding VNFFG of VNFFGD, and then further determine that out each VNF example in the VNFFG Between the 2nd VL examples.

So, VNSM just can determine to be somebody's turn to do according to the corresponding specification informations of VNFD and VNFD Which VNF example is needed in VNS examples, it is true according to the corresponding specification informations of VLD and VLD Which the 2nd VL example is needed in the fixed VNS examples, these VNF examples and the 2nd VL Example just constitutes the VNS.

It should be noted that step 401 is the entity being arranged in addition to NFVO with VNSM setting For what is be above illustrated, it is understood that, if VNSM is arranged in NFVO, i.e. VNSM It is integrated on an entity device with NFVO, now, in step 401, VNSM need not be obtained Above-mentioned VNS instantiations request is taken, VNSM itself can determine to carry out by calling corresponding data The 2nd VL that the VNF examples and VNS examples described in composition that VNS instantiation operations need need Example.

Step 402 is optional step, and in step 402, VNSM checks that VNS instantiations please The validity asked.For example, check the VNS instantiation request sender whether be authorized to etc..Its In, if current VNS includes multiple VNFFG and policing rule, perhaps policing rule can lead It is effective for the NS to cause only part VNFFG.

Specifically, according in step 401 VNS instantiation request in carry VNSD mark with And the mark of specification information, VNSM can further determine that the VNF examples needed in the VNS examples, Now, in step 403, VNSM can search the VNF for needing by checking historical record Example whether there is.

In step 404, illustrated in step 401, asked because the VNS is instantiated The VLD in the VNS is carried in indicated VNSD, and the VLD can be used to describe VL, Therefore, VNSM can ask the VIM to perform VL instantiation operations according to the VLD, be somebody's turn to do The 2nd VL examples in VNS.

It should be noted that because one or more VL in the VNS examples may have been carried out Instantiation operation, therefore, that is, the 2nd VL examples having may be present, therefore, VNSM is only Needs are extended on existing 2nd VL examples.

In step 405, if the VNF examples do not exist in step 403, VNSM is performed VNF instantiation operations, obtain the VNF examples.Wherein, VNF instantiation operations and prior art The process of middle VNF instantiations is identical, so be in not repeating.

By step 401-405, can obtain in VNS examples required all in a VNFFG VNF examples and the 2nd VL examples, therefore, in a step 406, VNSM and VIM is carried out Communication, connection request is sent to VIM, asks the VNF examples that the VIM will be obtained in step 405 Set up with the 2nd VL examples obtained in step 404 and be connected.

If all VNFFG in the VNS examples have been instantiated, step 407 is performed, i.e., The transmitting terminal (for example, NFVO) that VNSM sets up the VNS examples to request sends VNS examples Change operation completion message, confirm that the VNS instantiation operations are completed.

Wherein, the step of being related to VNSM to perform in above-mentioned steps 401-407, can be by VNSM The programmed instruction stored in computing device memory in above-mentioned Fig. 5 is realized.

So far, embodiments of the invention provide a kind of method of VNS instantiations, are applied to introduce VNS The NVF systems of concept, wherein, VNSM determines to carry out the VNF of VNS instantiation operation needs The 2nd VL examples that example and composition VNS examples need；And then, VNSM performs VNF realities Exampleization is operated and VL instantiates behaviour, to obtain the VNF examples and the 2nd VL examples；VNSM to VIM sends connection request, to cause that VIM sets up VNF examples and the 2nd VL according to connection request Connection between example.So, in this NFV systems, VNSM can be responsible for setting up VNS Example, and the VNF examples and the 2nd VL examples in a VNS example are managed and safeguarded, And NFVO is only needed without being scheduled to the VNF examples and the 2nd VL examples in VNS examples VNS examples where VNF examples are managed, so as to reduce NFVO operation and Complexity in maintenance process, improves dispatching efficiency.

Based on the NFV systems shown in Fig. 2, embodiments of the invention provide a kind of expansion of VNS examples Appearance method, as shown in Figure 10, the method includes：

501st, VNSM receives the dilatation request of the VNS examples that NFVO sends, dilatation request In carry the mark of specification information more than current VNS capacity.

In step 501, VNSM obtains the dilatation request of VNS examples, for example, from NFVO The dilatation request for the VNS examples is received, wherein, carry to be more than in dilatation request and work as The mark of the specification information of preceding VNS capacity.

Referring to step 204a in Fig. 7, when above-mentioned NS dilatations operation is carried out, when NFVO needs When carrying out dilatation to VNS examples, the dilatation that can send the VNS examples to VNSM is asked, with So that VNSM performs following step 502-505, to complete VNS example dilatations.
