It should be noted that, in embodiments of the present invention, term " first ", " second ", " third " are used for description purposes only, for distinguishing different description objects, being not understood to indicate or imply relative importance or implicitly indicating the quantity of indicated technical characteristic.

The embodiment of the present invention provides a kind of dispositions method of virtual resource, as shown in Fig. 2, this method may include:

S101, management node send first resource to VIM and dispose request message, first resource deployment request message is for requesting VIM to dispose virtual resource to be disposed, it include at least one dummy unit in the virtual resource, which, which disposes, carries dependability parameter corresponding with the virtual resource in request message.

Wherein, which is used to be characterized in a region maximum quantity for allowing the dummy unit disposed.

It should be noted that in embodiments of the present invention, the expression-form of dependability parameter can include but is not limited at least one of absolute reference, relative parameter, ratio and grade.

Specifically, such as 1,2,5 etc. numerical value can indicate absolute reference, by taking absolute reference 2 as an example, 2 dummy units can be disposed by being characterized in the same region at most, for example, at most disposing 2 VM for forming the VNF on one host when instantiating some VNF, 2 VNF for forming the NS are at most disposed when instantiating some NS, within the scope of a piece of suburb.

10%, the numerical value such as 20%, 30% can indicate relative parameter, and by taking relative parameter 20% as an example, 20% dummy unit of the quantity of multiple dummy units can at most be disposed by being characterized in a region.Such as forming the quantity of the VM of some VNF is 10, when instantiation should When VNF, 10*20%=2 VM is at most disposed on one host.

1/2, the numerical value such as 1/3,2/5 can indicate ratio, and by taking ratio 1/3 as an example, 1/3 dummy unit of the quantity of multiple dummy units can at most be disposed by being characterized in a region.Such as forming the quantity of the VNF of some NS is 8, when instantiating the NS, at most disposes 2 VNF (8*1/3 round numbers) on one host.

Optionally, reliability can also be divided into multiple grades, such as reliability can be divided into highest, high, medium and low and minimum five grades, corresponding dependability parameter is 0%, 25%, 50%, 75% and 100%.

It should be noted that network maintenance staff can be pre-planned previously according to network deployment scenario, corresponding dependability parameter is set in each descriptor, and descriptor may include VNFD or NSD.To which the dependability parameter can be obtained from descriptor corresponding with the virtual resource when management node needs dispose the virtual resource wait dispose, sent so that the dependability parameter be carried and be sent to VIM in first resource deployment request message.

Specifically, dependability parameter can be set in the operational blocks which partition system in VNFD, such as the deployment of VNF module describes template (English: virtualised development unit, abbreviation: VDU), internal virtual link (English: internal virtual link descriptor, abbreviation: IVLD) or IVL descriptor (English: IVL descriptor, abbreviation: IVLD) etc..

Therefore, management node can specifically obtain preset dependability parameter from VNFC, VDU, IVL, IVLD or deployment customizedization.

Dependability parameter also can be set in the operational blocks which partition system in NSD, such as VL or VNFFG etc..

Therefore, management node can specifically obtain preset dependability parameter from VL or VNFFG.

It should be noted that in embodiments of the present invention, management node can be NFVO, it can also be with VNFM.When management node is NFVO, descriptor can be VNFD, or NSD, NFVO can carry out the deployment of virtual resource by obtaining the information in VNFD to VNF, can also carry out the deployment and maintenance of virtual resource to NS by obtaining the information in NSD.

When management node is VNFM, descriptor can be VNFD, and VNFM can lead to It crosses and obtains deployment and maintenance that the information in VNFD carries out virtual resource to VNF.

S102, VIM receive the first resource that management node is sent and dispose request message.

S103, VIM are according to the dependability parameter, the quantity at least one region that the VIM is managed, and the quantity of at least one dummy unit, determine that the request results of first resource deployment request message, the request results include the request success or failure of first resource deployment request message.

It should be noted that requesting for first resource deployment request message successfully includes VIM success according to the dependability parameter progress resource deployment carried in first resource deployment request message.The request of first resource deployment request message unsuccessfully includes that VIM can not carry out resource deployment according to the dependability parameter.

Specifically, above-mentioned S103 can specifically include:

VIM determines whether the quantity at least one region meets the dependability parameter according to the quantity of at least one dummy unit, the quantity at least one region and the dependability parameter.

Wherein, if VIM determines that the quantity at least one region is unsatisfactory for the dependability parameter, VIM determines the request failure of first resource deployment request message.

If VIM determines that the quantity at least one region meets the dependability parameter, VIM determines the request success of first resource deployment request message.

Illustratively, in order to better illustrate VIM according to the quantity of at least one dummy unit, the quantity at least one region, and the dependability parameter, determine whether the quantity at least one region meets the dependability parameter, below at least one dummy unit for 8 VM, which is illustratively illustrated for being 2.

It after VIM receives first resource deployment request message, is determined according to first resource deployment request message and needs to dispose 8 VM, and dependability parameter is 2, then VIM determines that disposing 8 VM at least needs 8/2=4 platform host.

Assuming that, at least one region that the VIM is managed is 3 hosts, due to when 8 VM are deployed on 3 hosts, need to dispose 2 or more VM on an at least host, therefore and do not meet dependability parameter 2, and according to dependability parameter 2, it disposes 8 VM and at least needs 4 hosts, since 3 less than 4, VIM determines its management The quantity of host be unsatisfactory for the dependability parameter, and then VIM determines the request failure of first resource deployment request message, i.e. VIM is determined according to the dependability parameter, can not on 3 platforms successful deployment 8 VM.

Assuming that, at least one region that the VIM is managed is 5 hosts, since 5 greater than 4, therefore, VIM determines that the quantity of the host of its management meets the dependability parameter, and then VIM determines the request success of first resource deployment request message, i.e. VIM is determined according to the dependability parameter, being capable of successful deployment 8 VM on 5 hosts.

S104, VIM send resource deployment response message to management node according to the request results, which is used to indicate the request success or failure of the first resource deployment request message.

S105, management node receive the resource deployment response message that VIM is sent.

In embodiments of the present invention, due to management node to VIM request resource deployment when, preset dependability parameter is carried and is sent to VIM in resource deployment request message, to which VIM can carry out the deployment of virtual resource according to the dependability parameter, limit the maximum quantity for the dummy unit that the VIM on a region allows to dispose, all virtual resources may be deployed on a region so as to avoid VIM in the prior art, carry out the reliability for improving resource deployment.

Further, on the one hand, in the request failure of first resource deployment request message, management node and VIM can execute the following two kinds subsequent operation.

(1) if, VIM determine first resource deployment request message request failure, then above-mentioned resource deployment response message is used to indicate the request failure of first resource deployment request message, and the quantity at least one region that VIM is managed is carried in the resource deployment response message, the quantity at least one region changes dependability parameter for the management node, so that the dependability parameter after change meets the quantity in the region that the VIM is managed.

Specifically, if VIM determines the request failure of first resource deployment request message, in conjunction with Fig. 2, as shown in figure 3, after above-mentioned S105, this method further include:

S106, management node change the dependability parameter, the dependability parameter after change meets the quantity at least one region according to the quantity of the quantity at least one region and at least one dummy unit.

Illustratively, it is assumed that at least one dummy unit includes 8 VM, which includes 3 hosts.After management node receives the resource deployment response message that VIM is sent, determine the request failure of first resource deployment request message, and determine totally 3, host that VIM is managed, and then management node can determine that capableing of the deployment scheme of 8 VM of successful deployment on 3 hosts may include " 008 " and " 017 ", it respectively indicates on same 1 host that 8 VM are deployed in 3 hosts, it is deployed on certain 1 host in 3 hosts with 1 VM, in addition 7 VM are deployed on other 1 host in 3 hosts.And so on, the confirmable deployment scheme of management node further includes " 026 ", " 035 ", " 044 ", " 116 ", " 125 ", " 134 ", " 224 ", and " 233 ".

Since the maximum quantity for the dummy unit for allowing to dispose on a region is fewer, reliability is higher, therefore, management node can determine the least deployment scheme of dummy unit in area top administration, i.e. " 233 " are the highest deployment scheme of reliability in this 10 deployment schemes, maximum quantity in the deployment scheme in the dummy unit of area top administration is 3, i.e., the corresponding dependability parameter of the deployment scheme is 3, therefore dependability parameter can be changed to 3 by original 2 by management node.Dependability parameter after change meets the quantity at least one region.

S107, management node send Secondary resource to VIM and dispose request message, carry the dependability parameter after the change in Secondary resource deployment request message.

It is worth noting that, in embodiments of the present invention, after the request failure of first resource deployment request message, management node can be according to actual physical resource, that is the quantity at least one region that the VIM is managed is modified preset dependability parameter originally, and it is changed to meet the parameter of the quantity at least one region, and the dependability parameter after change is carried in Secondary resource deployment request message, it is sent to VIM, to request VIM to be disposed according to the virtual resource that the dependability parameter after the change treats deployment again.Since the dependability parameter after change meets the quantity at least one region, after VIM receives Secondary resource deployment request message, VIM can be according to the dependability parameter after change, successful deployment virtual resource at least one region.

It is understood that in the dispositions method of virtual resource provided in an embodiment of the present invention, it, can be in the region that VIM is managed since preset dependability parameter has adjustability Quantity when being unsatisfactory for preset dependability parameter, which is modified, with guarantee virtual resource can successful deployment on the area, and guarantee the reliability of virtual resource deployment, improve the flexibility of virtual resource deployment.

Optionally, in practical applications, there are a kind of possible application scenarios, i.e., according to the needs of Practical Project, during carrying out virtual resource deployment, it is necessary to carry out resource deployment in strict accordance with preset dependability parameter, i.e., not allow to change dependability parameter.So in embodiments of the present invention, a first term can be set in descriptor, be used to indicate whether that management node is allowed to change preset dependability parameter in the descriptor.

Specifically, characterizing allows management node to change dependability parameter if first term is opened；If first term is closed, characterizing does not allow management node to change dependability parameter.

Illustratively, first term can be a flag bit, if the flag bit is assigned a value of 1, then it represents that first term is opened, if the flag bit is assigned a value of 0, then it represents that first term is closed；The closing and unlatching of the first term can also be characterized with character string off and on, in this regard, the embodiment of the present invention is with no restrictions.

Further, management node is according to the quantity at least one region and the quantity of at least one dummy unit, it changes before the dependability parameter, management node can first inquire whether preset first term in the descriptor for saving the dependability parameter is opened, if the first term is opened, the step of management node is the quantity of the executable quantity according at least one region and at least one dummy unit, changes the dependability parameter.Otherwise, management node is not modified the dependability parameter, in this case, management node can prompt the request failure of first resource deployment request message to network maintenance staff, and the quantity at least one region is notified to network maintenance staff, to which network maintenance staff can know the lazy weight in the region that VIM is managed, and then network maintenance staff can increase deployment physical resource, so that the physical resource can satisfy the demand for disposing virtual resource to be disposed, so that virtual resource to be disposed can dependability parameter as requested successfully disposed.

(2) if, the request failure of first resource deployment request message, which is used to indicate the request failure of first resource deployment request message.

Further, before above-mentioned S104, this method further include:

S1, the VIM are according to the quantity at least one region and at least one dummy unit Quantity, change the dependability parameter, the dependability parameter after change meets the quantity at least one region.

I.e. in present example, VIM can voluntarily modify to the dependability parameter, determine the dependability parameter that the quantity in the region that the VIM is managed meets.

Specifically, VIM is according to the quantity at least one region and the quantity of at least one dummy unit, change the specific method of the dependability parameter, management node be may refer in above-mentioned S106 according to the quantity at least one region and the quantity of at least one dummy unit, the specific method of the dependability parameter is changed, details are not described herein again.

Further, after dependability parameter after VIM determines the change, the dependability parameter after the change can be carried and is sent to management node in resource deployment response message, to inquire whether management node can be used the dependability parameter after the change.

Further, after above-mentioned S105, the method also includes:

S2, management node are determined whether using the dependability parameter after the change.

Illustratively, management node can save whether first term in the descriptor of the dependability parameter is opened by inquiry, if the first term is opened, management node determination allows using the dependability parameter after the change；If the first term is closed, management node determination does not allow using the dependability parameter after the change.

Management node can also by network maintenance staff prompt the VIM send the change after dependability parameter, determined whether according to the instruction of network maintenance staff using the dependability parameter after the change.

It should be noted that management node determines whether the mode using the dependability parameter after the change, the needs that can be had more in Practical Project are configured, and the present invention is with no restriction.

S3, management node send change response message to VIM, which is used to indicate whether to allow the dependability parameter using after the change.

S4, VIM receive the change response message of management node transmission.

If S5, the change response message are used to indicate the dependability parameter allowed using after the change, VIM disposes the virtual resource according to the dependability parameter after the change.

On the other hand, if the request success of first resource deployment request message, VIM is at least The deployment of virtual resource can be carried out according to dependability parameter by the following two kinds mode.

Mode one, in conjunction with Fig. 2, as shown in figure 4, before above-mentioned S104, this method further include:

S108, VIM determine at least one deployment scheme for meeting that the dependability parameter and VIM allow according to the quantity of at least one dummy unit and at least one region.

Illustratively, for dependability parameter for 4,8 VM and 3 hosts.

According to dependability parameter 4, VIM determines that all deployment schemes for capableing of 8 VM of successful deployment on 3 hosts, all deployment schemes which allows include " 044 ", " 134 ", " 224 ", and " 233 ".Wherein, the least deployment scheme of VM is disposed in these deployment schemes on a host since deployment scheme " 233 " are, deployment scheme " 233 " is the highest deployment scheme of reliability in all deployment schemes of VIM permission.

After VIM determines all deployment schemes for meeting the dependability parameter and VIM permission, at least one of all deployment schemes deployment scheme can be carried and be sent to management node in the resource deployment response message by VIM.

It should be noted that, at least one deployment scheme may include all deployment schemes that the VIM allows, that is all deployment schemes that the VIM can allow the VIM, which are carried, is sent to management node in resource deployment response message, to request management node to select a kind of deployment scheme from all deployment schemes that the VIM allows.

At least one deployment scheme may include the highest deployment scheme of reliability in all deployment schemes of VIM permission, that is VIM can first select the highest deployment scheme of reliability in all deployment schemes that the VIM allows, the highest deployment scheme of the reliability is carried again and is sent to management node in resource deployment response message, to inquire whether management node can carry out resource deployment according to the highest deployment scheme of the reliability.

Further, in mode one, after above-mentioned S105, this method further include:

S109, management node determine the first deployment scheme from at least one deployment scheme.

I.e. when management node receives resource deployment response message, determine the request success of first resource deployment request message, and after at least one deployment scheme for knowing VIM permission in the resource deployment response message, management node can randomly choose a kind of deployment scheme as the first deployment scheme from at least one deployment scheme, also can choose at least one deployment As the first deployment scheme, the present invention is not especially limited a kind of highest deployment scheme of reliability in scheme.

S110, management node send resource deployment instruction message to VIM, carry first deployment scheme in the resource deployment instruction message.

After management node determines the first deployment scheme from at least one deployment scheme, which can be carried and be sent to VIM in the resource deployment instruction message, to indicate that VIM disposes virtual resource according to the first deployment scheme.

S111, VIM receive the resource deployment instruction message that management node is sent.

S112, VIM affix one's name to the virtual resource at least one area top according to the first deployment scheme.

Illustratively, in conjunction with the citing in above-mentioned S107, it is assumed that the first deployment scheme is " 233 ", then VIM can dispose 2 VM on the wherein host in 3 hosts, in addition disposes 3 VM respectively on two hosts.

Mode two, in conjunction with Fig. 2, as shown in figure 5, before above-mentioned S104, this method further include:

S113, VIM determine the first deployment scheme according to deployment scheme selection rule from at least one deployment scheme.

It should be noted that management node also carries deployment scheme selection rule into the first resource deployment request message that VIM is sent in mode two, deployment scheme selection rule determines the first deployment scheme for VIM from least one deployment scheme.

Illustratively, deployment scheme selects rule can be to select the highest deployment scheme of reliability from least one deployment scheme, for example, the citing in embodiment as shown in Figure 4, selects deployment scheme " 233 ".Deployment scheme selection rule may be to need the least deployment scheme of the number in region, for example, the citing in embodiment as shown in Figure 4, it selects deployment scheme " 044 ", in the deployment scheme, it is only necessary to which two hosts can be according to the requirement of dependability parameter 4,8 VM of successful deployment.

S114, VIM affix one's name to the virtual money at least one area top according to the first deployment scheme Source.

Further, after VIM completes the deployment of virtual resource according to first deployment scheme, resource deployment response message can be sent to management node, to indicate the request success of management node first resource deployment request message.

It is worth noting that, the dispositions method of virtual resource provided by the invention, it can be applied in plurality of application scenes, such as the instantiation of VNF, the instantiation of NS, the expansion process of VNF, the extension of NS, the scenes such as the migration of VNF and the migration of NS include the deployment process of virtual resource in these scenes.

Wherein, the deployment of virtual resource can be the reserved of virtual resource, the distribution of virtual resource or the migration of virtual resource.

Further, if the deployment of virtual resource refers specifically to the distribution of virtual resource, above-mentioned first resource deployment request message is specially first resource allocation request message, and the first resource allocation request message is for requesting VIM to distribute the virtual resource；If the deployment of virtual resource refers specifically to the reserved of virtual resource, above-mentioned first resource deployment request message is specially first resource reservation requests, and the first resource reservation requests are for requesting VIM to reserve the virtual resource；If the deployment of virtual resource refers specifically to the migration of virtual resource, then above-mentioned first resource deployment request message is specially first resource migration request message, and at least one region that the first resource migration request message is used to request VIM that the virtual resource is moved to VIM management.

It should be noted that, due in the instantiation process of VNF or the expansion process of VNF, resource allocation request message can be sent from VNFM to VIM, requesting VIM is that VNF distributes virtual resource, therefore, when the dispositions method of virtual resource provided in an embodiment of the present invention, applied in the instantiation process of VNF or the expansion process of VNF, and the deployment of virtual resource, when referring specifically to the distribution of virtual resource, management node can be VNFM.

Particularly, when management node is VNFM, VNFM can have the function of change dependability parameter, so that VNFM can voluntarily change dependability parameter when the request of first resource allocation request message failure.Certainly, VNFM may not possess the function of change dependability parameter, so that VNFM can request NFVO to be modified dependability parameter when the request of first resource allocation request message failure.

It is understood that NFVO receives the request of VNFM if being provided with first term in descriptor, before modifying to dependability parameter, first inquire whether the first term is opened, and when switching mode is opened, the request for responding VNFM, modifies to dependability parameter.

Specifically, as shown in fig. 6, when VNFM does not have the function of change dependability parameter, and in the case where the request of first resource allocation request message failure, the method for virtual resource provided in an embodiment of the present invention deployment may include:

S201, VNFM send first resource allocation request message to VIM, carry dependability parameter in the first resource allocation request message.

S202, VIM receive the first resource allocation request message that VNFM is sent.

S204, VIM send resource deployment response message to VNFM, which is used to indicate the request failure of the first resource allocation request message, the quantity at least one region is carried in the resource deployment response message.

S205, VNFM receive the resource deployment response message that VIM is sent.

S206, VNFM send the quantity at least one region and the quantity of at least one dummy unit to NFVO.

Wherein, the quantity at least one region and the quantity of at least one dummy unit can be carried in the message for carrying out information transmission between VNFM and VNFO and be sent to NFVO by VNFM.

S207, NFVO change the dependability parameter according to the quantity of the quantity at least one region and at least one dummy unit.

S208, NFVO send the dependability parameter after change to VNFM.

After S209, VNFM receive the dependability parameter after the change of NFVO transmission, Secondary resource allocation request message is sent to VIM, carries the dependability parameter after the change in the Secondary resource allocation request message.

It in turn, can be according to change after VIM receives Secondary resource allocation request message Dependability parameter afterwards carries out the deployment of virtual resource.It is understood that since modified dependability parameter meets the quantity in the region that the VIM is managed, VIM, which can succeed, carries out the deployment of virtual resource according to modified dependability parameter.

Present example provides a kind of dispositions method of virtual resource, management node can carry dependability parameter in first resource deployment request message, due to the dependability parameter characterize allow in a region dispose dummy unit maximum quantity, therefore after VIM VIM receives first resource deployment request message, it can determine the maximum quantity for the dummy unit that can be disposed in a region, and the deployment of virtual resource is carried out according to the dependability parameter, all virtual resources may be deployed on one region by avoiding VIM in the prior art in turn, improve the reliability of resource deployment.
