Description

Virtual resource deployment method, device and system

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for deploying virtual resources.

Background

With the rapid development of virtualization technology, Network Function Virtualization (NFV) systems, which implement functions of network element devices dedicated to networks, are gaining attention on general physical devices.

In the NFV system, a function virtualization scheduling Node (NFVO) or a virtual network function management node (VNFM) sends a resource deployment request message to a virtual machine infrastructure management node (VIM) to request the VIM to deploy a virtual resource to be deployed in an area managed by the VIM. For example, when a certain Virtual Network Function (VNF) is instantiated, the NFVO or the VNFM sends a resource deployment request message to the VIM, and the VIM deploys Virtual Machines (VMs) required for forming the VNF on a host (host) managed by the VIM according to the resource deployment request message.

However, according to the foregoing method for virtual resource deployment, when the virtual resources of the VNF include multiple VMs, for example, 5 VMs, and the VIM may deploy the 5 VMs on one host, when the host fails, none of the 5 VMs may be operated, and therefore, the reliability of virtual resource deployment may be low according to the foregoing method for resource deployment.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a block diagram of an NFV system. The NFV system includes: network function virtualization scheduling Node (NFVO), virtual network function management node (VNFM), virtual machine infrastructure management node (VIM), Operation Support System (OSS) or Business Support System (BSS), network element management node (EMs, EM), VNF, virtual network function infrastructure (NFVI), network service (vnns) directory, and directory f, etc.

In the NFV system, NFVO, VNFM, and VIM form a management and orchestration (NFV-MANO) domain of the NFV system, where NFVO may also be referred to as a network function virtualization orchestrator, and OSS/BSS may also be referred to as a network management Node (NM).

Wherein, the EM performs function configuration, fault management, recording of function use condition, performance statistics, security management, and the like for one or more VNFs.

The VNF is a virtualized logical network element, such as SGSN, MME, GGSN, SGW, PGW, etc. in the field of telecommunication packet, and each network element can be deployed independently and appears as one VNF.

NFVI provides the VNF with hardware resources and virtualized resources and management thereof, as well as a virtualized execution environment.

NFVO is responsible for the life cycle management of NS and can orchestrate the resources of NFVI by instructing VIM.

The VNFMs are responsible for lifecycle management of VNFs, each VNF having an associated VNFM. One VNFM may manage one VNF and may also manage multiple VNFs of the same type or even different types.

The NS directory stores a Network Service Descriptor (NSD), which is a template for describing the deployment and maintenance behavior of the NS, and includes a service topology and characteristics of the NS, where the service topology includes various components and relationships between VNFs, a Virtual Link (VL), a VNF forwarding table (VNF forwarding graph, VNFFG), and the like, and can be read by the NFVO. NFVO operates to deploy and maintain virtual resources to the NS, typically according to VSDs.

The VNF directory stores VNF descriptors (english: VNF descriptors, abbreviated as VNFD), which are templates describing VNF deployment and maintenance behaviors and can be read by VNFM or NFVO, software images, files, and the like. VNFM or NFVO typically performs operations of deployment and maintenance of virtual resources on VNF according to VNFD.

The VIM is responsible for controlling and managing resources in the VNFI infrastructure, including: computing resources, storage resources, network resources, etc., which are typically an operator's infrastructure.

a virtual unit is a basic unit in a deployment process of a virtual resource, for example, when a VNF is instantiated, a plurality of VMs forming the VNF need to be deployed, where each VM of the plurality of VMs is a virtual unit; when an NS is instantiated, multiple VNFs constituting the NS need to be deployed, and each VNF in the multiple VNFs is a virtual unit.

The region is a region range in which reliability is limited in the deployment process of the virtual resources. For example, for VNF, a region may refer to a host (host), a cabinet (shelf), etc., and for NS, a region may refer to a specific geographic region, such as a suburban area, a city area, etc.

The reliability parameter is expressed in the maximum number of virtual units allowed to be deployed in a region in the process of deploying the virtual resource, and it can be understood that the smaller the number of virtual units allowed to be deployed in a region, the higher the reliability of the NS or VNF composed of the virtual resource is.

It should be noted that any one of the functional nodes in the NFV system may be distributed on one entity device, or may be distributed on multiple entity devices, and multiple functional nodes in the NFV system may be distributed on different entity devices, or may be distributed on the same entity device. It is to be understood that any functional node in the NFV system may be a logical functional module in an entity device, or may be a logical functional module composed of a plurality of entity devices.

Therefore, in the embodiment of the present invention, one entity device may execute each step in the method provided in the embodiment of the present invention, and a plurality of entity devices may cooperate to execute each step in the method provided in the embodiment of the present invention, which is not limited to this.

Further, in order to more clearly describe the deployment method of virtual resources provided by the present invention, the following description uses a logic function module (i.e. a function node in the NFV system) as an execution subject or a control object, and it should be understood by those skilled in the art that the logic function module depends on hardware resources on an entity device where the logic function module is located when being specifically implemented.

In the embodiment of the present invention, the NFV system may be applied to a Long Term Evolution (LTE) communication system, and may also be applied to an LTE evolution communication system, such as an LTE-a (long term evolution advanced) system, and may also be applied to a third Generation mobile communication (3 rd-Generation, abbreviated as 3G) system, such as WCDMA, and the like, which are not limited in the present invention.

It should be noted that, in the embodiments of the present invention, the terms "first", "second" and "third" are used for descriptive purposes only and are used for distinguishing different descriptive objects, and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

An embodiment of the present invention provides a method for deploying virtual resources, and as shown in fig. 2, the method may include:

s101, a management node sends a first resource deployment request message to a VIM, wherein the first resource deployment request message is used for requesting the VIM to deploy a virtual resource to be deployed, the virtual resource comprises at least one virtual unit, and the first resource deployment request message carries a reliability parameter corresponding to the virtual resource.

Wherein the reliability parameter is used to characterize a maximum number of virtual units allowed to be deployed within an area.

It should be noted that, in the embodiment of the present invention, the expression form of the reliability parameter may include, but is not limited to, at least one of an absolute parameter, a relative parameter, a ratio, and a grade.

Specifically, for example, the values such as 1, 2, 5, etc. may represent absolute parameters, and take the absolute parameter 2 as an example, to characterize that at most 2 virtual units may be deployed in the same area, for example, when a certain VNF is instantiated, at most 2 VMs constituting the VNF are deployed on one host, and when a certain NS is instantiated, at most 2 VNFs constituting the NS are deployed in a suburban area.

The values of 10%, 20%, 30%, etc. may represent relative parameters, and for example, 20% of the relative parameters may represent virtual units that represent at most 20% of the number of virtual units that may be deployed in an area. For example, the number of VMs constituting a certain VNF is 10, and when the VNF is instantiated, a maximum of 10 × 20% ═ 2 VMs are deployed on one host.

The 1/2, 1/3, 2/5, etc. values may represent ratios, with the ratio 1/3 being an example, to characterize a virtual unit that may be deployed in an area up to 1/3 of the number of multiple virtual units. For example, the number of VNFs constituting an NS is 8, and when the NS is instantiated, a maximum of 2 VNFs are deployed on one host (8 × 1/3 is an integer).

Optionally, the reliability may be further divided into a plurality of levels, for example, the reliability may be divided into the highest, high, medium, low, and the lowest five levels, which respectively correspond to the reliability parameters of 0%, 25%, 50%, 75%, and 100%.

It should be noted that, the network maintenance personnel may set a corresponding reliability parameter in each descriptor according to the pre-planned deployment situation of the network in advance, and the descriptor may include VNFD or NSD. Therefore, when the management node needs to deploy the virtual resource to be deployed, the reliability parameter can be obtained from the descriptor corresponding to the virtual resource, and the reliability parameter is carried in the first resource deployment request message and is sent to the VIM.

Specifically, the reliability parameter may be set in any module in the VNFD, for example, a deployment description template (VDU) of the VNF module, an Internal Virtual Link (IVLD) or an IVL descriptor (IVL descriptor, IVLD) of the VNF module, and the like.

Therefore, the management node may specifically obtain the preset reliability parameters from VNFC, VDU, IVL, IVLD, or deployment customization.

The reliability parameter may also be set in any module in NS D, such as VL or VNFFG.

Therefore, the management node may specifically obtain the preset reliability parameter from VL or VNFFG.

It should be noted that, in the embodiment of the present invention, the management node may be an NFVO or a VNFM. When the management node is an NFVO, the descriptor may be a VNFD or an NSD, and the NFVO may perform virtual resource deployment on the VNF by acquiring information in the VNFD or perform virtual resource deployment and maintenance on the NS by acquiring information in the NSD.

When the management node is a VNFM, the descriptor may be a VNFD, and the VNFM may perform deployment and maintenance of virtual resources on the VNF by acquiring information in the VNFD.

S102, the VIM receives a first resource deployment request message sent by the management node.

S103, the VIM determines a request result of the first resource deployment request message according to the reliability parameter, the number of the at least one region managed by the VIM, and the number of the at least one virtual unit, where the request result includes a request success or a request failure of the first resource deployment request message.

It should be noted that the request success of the first resource deployment request message includes that the VIM successfully performs resource deployment according to the reliability parameter carried in the first resource deployment request message. The request failure of the first resource deployment request message includes that the VIM cannot deploy the resource according to the reliability parameter.

Specifically, the S103 may specifically include:

the VIM determines whether the number of the at least one region satisfies the reliability parameter according to the number of the at least one virtual unit, the number of the at least one region, and the reliability parameter.

Wherein if the VIM determines that the number of the at least one region does not satisfy the reliability parameter, the VIM determines that the request of the first resource deployment request message failed.

For better illustration, in order to better illustrate that the VIM determines whether the number of the at least one region satisfies the reliability parameter according to the number of the at least one virtual unit, the number of the at least one region, the following is an exemplary description taking the at least one virtual unit as 8 VMs, and the reliability parameter as 2.

After receiving the first resource deployment request message, the VIM determines that 8 VMs need to be deployed according to the first resource deployment request message, and if the reliability parameter is 2, the VIM determines that at least 8/2 of the 8 VMs needs to be deployed — 4 hosts.

Assuming that at least one area managed by the VIM is 3 hosts, since at least one host needs to deploy 2 or more VMs when the 8 VMs are deployed on 3 hosts, the at least one host does not meet the reliability parameter 2, and since 3 is less than 4, the VIM determines that the number of hosts managed by the VIM does not meet the reliability parameter, and further, the VIM determines that the request of the first resource deployment request message fails, that is, the VIM determines that the 8 VMs cannot be successfully deployed on 3 hosts according to the reliability parameter, since the number of hosts managed by the VIM is less than 4.

Assuming that the at least one region managed by the VIM is 5 hosts, since 5 is greater than 4, the VIM determines that the number of hosts managed by the VIM satisfies the reliability parameter, and further determines that the request of the first resource deployment request message is successful, that is, the VIM determines that the 8 VMs can be successfully deployed on the 5 hosts according to the reliability parameter.

And S104, the VIM sends a resource deployment response message to the management node according to the request result, wherein the resource deployment response message is used for indicating the success or failure of the request of the first resource deployment request message.

And S105, the management node receives the resource deployment response message sent by the VIM.

In the embodiment of the invention, when the management node requests the VIM for resource deployment, the preset reliability parameter is carried in the resource deployment request message and sent to the VIM, so that the VIM can deploy the virtual resources according to the reliability parameter, the maximum number of virtual units allowed to be deployed by the VIM in one area is limited, and the situation that the VIM possibly deploys all the virtual resources in one area in the prior art is avoided, and the reliability of resource deployment is improved.

Further, in an aspect, in case of a failure of the request of the first resource deployment request message, the management node and the VIM may perform the following two subsequent operations.

(1) If the VIM determines that the request of the first resource deployment request message fails, the resource deployment response message is used for indicating that the request of the first resource deployment request message fails, and the resource deployment response message carries the number of at least one region managed by the VIM, wherein the number of the at least one region is used for the management node to change the reliability parameter, so that the changed reliability parameter meets the number of the regions managed by the VIM.

Specifically, if the VIM determines that the request of the first resource deployment request message fails, referring to fig. 2, as shown in fig. 3, after S105, the method further includes:

s106, the management node changes the reliability parameter according to the number of the at least one region and the number of the at least one virtual unit, and the changed reliability parameter meets the number of the at least one region.

Illustratively, assuming that the at least one virtual unit includes 8 VMs, the at least one zone includes 3 hosts. After receiving the resource deployment response message sent by the VIM, the management node determines that the request of the first resource deployment request message fails, and determines that 3 hosts managed by the VIM are in total, and further, the management node may determine that the deployment schemes that can successfully deploy 8 VMs on 3 hosts may include "008" and "017", which respectively indicate that 8 VMs are all deployed on the same 1 host among the 3 hosts, and 1 VM is deployed on a certain 1 host among the 3 hosts, and another 7 VMs are deployed on another 1 host among the 3 hosts. By analogy, the deployment scenarios that the management node can determine also include "026", "035", "044", "116", "125", "134", "224", and "233".

Since the smaller the maximum number of virtual units allowed to be deployed in a region is, the higher the reliability is, the management node may determine the deployment scheme with the least virtual units deployed in a region, that is, "233" is the deployment scheme with the highest reliability among the 10 deployment schemes, and the maximum number of virtual units deployed in a region in the deployment scheme is 3, that is, the reliability parameter corresponding to the deployment scheme is 3, so the management node may change the reliability parameter from the original 2 to 3. The modified reliability parameter satisfies the number of the at least one region.

S107, the management node sends a second resource deployment request message to the VIM, wherein the second resource deployment request message carries the changed reliability parameters.

It should be noted that, in the embodiment of the present invention, after the request of the first resource deployment request message fails, the management node may change the originally preset reliability parameter according to the actual physical resource, that is, the number of the at least one region managed by the VIM, and change the originally preset reliability parameter into a parameter meeting the number of the at least one region, and carry the changed reliability parameter in the second resource deployment request message, and send the second resource deployment request message to the VIM, so as to request the VIM to deploy the virtual resource to be deployed according to the changed reliability parameter again. Since the changed reliability parameter satisfies the number of the at least one region, after receiving the second resource deployment request message, the VIM can successfully deploy the virtual resource in the at least one region according to the changed reliability parameter.

It can be understood that, in the deployment method of virtual resources provided in the embodiment of the present invention, because the preset reliability parameter has adjustability, when the number of the areas managed by the VIM does not meet the preset reliability parameter, the reliability can be changed to ensure that the virtual resources can be successfully deployed in the area, ensure the reliability of virtual resource deployment, and improve the flexibility of virtual resource deployment.

Optionally, in the actual application, there is a possible application scenario, that is, according to the requirement of the actual project, in the process of performing virtual resource deployment, resource deployment must be performed strictly according to the preset reliability parameter, that is, the reliability parameter is not allowed to be changed. Then in the embodiment of the present invention, a switch item may be set in the descriptor to indicate whether the management node is allowed to change the reliability parameter preset in the descriptor.

Specifically, if the switch item is turned on, the representation allows the management node to change the reliability parameter; and if the switch item is closed, the representation does not allow the management node to change the reliability parameter.

For example, the switch item may be a flag, and if the flag is assigned to 1, it indicates that the switch item is turned on, and if the flag is assigned to 0, it indicates that the switch item is turned off; the strings off and on may also be used to characterize the turning off and turning on of the switch item, and the embodiment of the present invention is not limited thereto.

Further, before the management node changes the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit, the management node may first query whether a switch item preset in a descriptor storing the reliability parameter is turned on, and if the switch item is turned on, the management node may perform the step of changing the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit. Otherwise, the management node does not modify the reliability parameter, and in this case, the management node may prompt a network maintainer that the request of the first resource deployment request message fails, and notify the network maintainer of the number of the at least one region, so that the network maintainer may know that the number of the regions managed by the VIM is insufficient, and then the network maintainer may increase the deployment of the physical resource, so that the physical resource may meet the requirement for deploying the virtual resource to be deployed, and thus the virtual resource to be deployed may be successfully deployed according to the required reliability parameter.

(2) And if the request of the first resource deployment request message fails, the resource deployment response message is used for indicating that the request of the first resource deployment request message fails.

Further, before the step S104, the method further includes:

and S1, the VIM modifies the reliability parameter according to the number of the at least one region and the number of the at least one virtual unit, wherein the modified reliability parameter satisfies the number of the at least one region.

That is, in the present embodiment, the VIM may modify the reliability parameter itself to determine a reliability parameter that satisfies the number of areas managed by the VIM.

Specifically, the specific method for the VIM to change the reliability parameter according to the number of the at least one region and the number of the at least one virtual unit may refer to the specific method for the management node to change the reliability parameter according to the number of the at least one region and the number of the at least one virtual unit in S106, and details are not described here.

Further, after the VIM determines the changed reliability parameter, the changed reliability parameter can be carried in a resource deployment response message and sent to the management node, so as to inquire whether the management node can use the changed reliability parameter.

Further, after S105, the method further includes:

s2, the management node determines whether to allow the changed reliability parameter to be used.

For example, the management node may determine that the changed reliability parameter is allowed to be used by querying whether a switch item in the descriptor storing the reliability parameter is turned on, and if the switch item is turned on; if the switch item is closed, the management node determines that the changed reliability parameter is not allowed to be used.

The management node may also determine whether to allow the use of the modified reliability parameter according to an instruction of a network maintainer by prompting the network maintainer of the modified reliability parameter sent by the VIM.

It should be noted that, the way of determining whether to allow the modified reliability parameter to be used by the management node may be set according to the actual requirement in the engineering, and the present invention is not limited thereto.

S3, the management node sends a change response message to the VIM, the change response message indicating whether the changed reliability parameters are allowed to be used.

S4, the VIM receives the change response message sent by the management node.

And S5, if the change response message is used for indicating that the changed reliability parameter is allowed to be used, the VIM deploys the virtual resource according to the changed reliability parameter.

On the other hand, if the request of the first resource deployment request message is successful, the VIM may deploy the virtual resource according to the reliability parameter in at least the following two ways.

First, referring to fig. 2, as shown in fig. 4, before the step S104, the method further includes:

and S108, the VIM determines at least one deployment scheme which meets the reliability parameter and is allowed by the VIM according to the number of the at least one virtual unit and the at least one region.

For example, the reliability parameters are 4, 8 VMs and 3 hosts.

From reliability parameter 4, the VIM determines all deployment scenarios that can successfully deploy 8 VMs on 3 hosts, including "044", "134", "224", and "233". Among them, since the deployment scenario "233" is the deployment scenario in which the VM is least deployed on one host among the deployment scenarios, the deployment scenario "233" is the deployment scenario with the highest reliability among all the deployment scenarios allowed by the VIM.

When the VIM determines that all deployment schemes that satisfy the reliability parameter and are allowed by the VIM, the VIM may send at least one deployment scheme of the all deployment schemes to the management node by carrying the deployment scheme in the resource deployment response message.

It should be noted that at least one deployment scenario may include all deployment scenarios allowed by the VIM, that is, the VIM may send all deployment scenarios allowed by the VIM to the management node by carrying them in a resource deployment response message, so as to request the management node to select one deployment scenario from all deployment scenarios allowed by the VIM.

At least one deployment scheme may include the deployment scheme with the highest reliability in all the deployment schemes allowed by the VIM, that is, the VIM may first select the deployment scheme with the highest reliability in all the deployment schemes allowed by the VIM, and then send the deployment scheme with the highest reliability in a resource deployment response message to the management node to inquire whether the management node may perform resource deployment according to the deployment scheme with the highest reliability.

Further, in the first mode, after S105, the method further includes:

s109, the management node determines a first deployment scheme from the at least one deployment scheme.

That is, after the management node receives the resource deployment response message, determines that the request of the first resource deployment request message is successful, and learns at least one deployment scheme allowed by the VIM from the resource deployment response message, the management node may randomly select one deployment scheme from the at least one deployment scheme as the first deployment scheme, or may select one deployment scheme with the highest reliability from the at least one deployment scheme as the first deployment scheme, which is not specifically limited in the present invention.

And S110, the management node sends a resource deployment indication message to the VIM, wherein the resource deployment indication message carries the first deployment scheme.

When the management node determines the first deployment scheme from the at least one deployment scheme, the management node may carry the first deployment scheme in the resource deployment indication message and send the resource deployment indication message to the VIM, so as to indicate the VIM to deploy the virtual resource according to the first deployment scheme.

And S111, the VIM receives the resource deployment indication message sent by the management node.

And S112, the VIM deploys the virtual resource on at least one area according to the first deployment scheme.

For example, in combination with the example in S107, assuming that the first deployment scenario is "233", the VIM may deploy 2 VMs on one host of the 3 hosts, and deploy 3 VMs on the other two hosts, respectively.

In a second mode, with reference to fig. 2, as shown in fig. 5, before the step S104, the method further includes:

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

It should be noted that, in the second mode, the first resource deployment request message sent by the management node to the VIM further carries a deployment scheme selection rule, where the deployment scheme selection rule is used by the VIM to determine the first deployment scheme from the at least one deployment scheme.

Illustratively, the deployment scenario selection rule may be to select the deployment scenario with the highest reliability from at least one deployment scenario, for example, as illustrated in the embodiment shown in fig. 4, the deployment scenario "233" is selected. The deployment scheme selection rule may also be a deployment scheme that requires the least number of areas, for example, as illustrated in the embodiment shown in fig. 4, a deployment scheme "044" is selected, in which only two hosts are required to successfully deploy 8 VMs according to the requirement of the reliability parameter 4.

S114, the VIM deploys the virtual resource on at least one area according to the first deployment scheme.

Further, after the VIM completes the deployment of the virtual resource according to the first deployment scenario, a resource deployment response message may be sent to the management node to indicate that the request of the first resource deployment request message is successful.

It is worth to be noted that the virtual resource deployment method provided by the present invention can be applied to various application scenarios, for example, scenarios such as instantiation of VNF, instantiation of NS, extension process of VNF, extension of NS, migration of VNF, and migration of NS, which all include virtual resource deployment processes.

The deployment of the virtual resource may be reservation of the virtual resource, allocation of the virtual resource, or migration of the virtual resource.

Further, if the deployment of the virtual resource specifically refers to allocation of the virtual resource, the first resource deployment request message is specifically a first resource allocation request message, and the first resource allocation request message is used for requesting the VIM to allocate the virtual resource; if the deployment of the virtual resource specifically refers to the reservation of the virtual resource, the first resource deployment request message is specifically a first resource reservation request message, and the first resource reservation request message is used for requesting the VIM to reserve the virtual resource; if the deployment of the virtual resource specifically refers to migration of the virtual resource, the first resource deployment request message is specifically a first resource migration request message, and the first resource migration request message is used for requesting the VIM to migrate the virtual resource to at least one area managed by the VIM.

It should be noted that, in the instantiation process of the VNF or the extension process of the VNF, the VNFM may send a resource allocation request message to the VIM, requesting the VIM to allocate a virtual resource to the VNF, so when the deployment method of a virtual resource provided in the embodiment of the present invention is applied to the instantiation process of the VNF or the extension process of the VNF, and the virtual resource deployment specifically refers to allocation of a virtual resource, the management node may be the VNFM.

In particular, when the management node is a VNFM, the VNFM may have a function of changing the reliability parameter, so that when the request of the first resource allocation request message fails, the VNFM may change the reliability parameter by itself. Of course, the VNFM may not have a function of changing the reliability parameter, so that when the request of the first resource allocation request message fails, the VNFM may request the NFVO to change the reliability parameter.

It can be understood that, if a switch item is set in the descriptor, the NFVO receives the VNFM request, queries whether the switch item is turned on before modifying the reliability parameter, and modifies the reliability parameter in response to the VNFM request when the switch type is turned on.

Specifically, as shown in fig. 6, when the VNFM does not have a function of changing the reliability parameter, and in a case that the request of the first resource allocation request message fails, the method for virtual resource deployment provided in the embodiment of the present invention may include:

s201, the VNFM sends a first resource allocation request message to the VIM, and the first resource allocation request message carries the reliability parameters.

S202, the VIM receives a first resource allocation request message sent by the VNFM.

S203, the VIM determines that the request of the first resource allocation request message fails according to the reliability parameter, the number of the at least one region managed by the VIM, and the number of the at least one virtual unit.

S204, the VIM sends a resource deployment response message to the VNFM, where the resource deployment response message is used to indicate that the request of the first resource allocation request message fails, and the resource deployment response message carries the number of the at least one region.

S205, the VNFM receives the resource deployment response message sent by the VIM.

S206, the VNFM sends the number of the at least one zone and the number of the at least one virtual unit to the NFVO.

Wherein the VNFM may send the number of the at least one zone and the number of the at least one virtual unit to the NFVO in a message carrying information transfer between the VNFM and the VNFO.

S207, the NFVO changes the reliability parameter according to the number of the at least one region and the number of the at least one virtual unit.

S208, the NFVO sends the changed reliability parameters to the VNFM.

S209, after receiving the modified reliability parameter sent by the NFVO, the VNFM sends a second resource allocation request message to the VIM, where the second resource allocation request message carries the modified reliability parameter.

Furthermore, after receiving the second resource allocation request message, the VIM may perform virtual resource deployment according to the changed reliability parameters. It can be understood that, since the modified reliability parameter satisfies the number of the regions managed by the VIM, the VIM can successfully perform the deployment of the virtual resource according to the modified reliability parameter.

The embodiment of the invention provides a deployment method of virtual resources, a management node can carry reliability parameters in a first resource deployment request message, and the reliability parameters represent the maximum number of virtual units allowed to be deployed in a region, so that after receiving the first resource deployment request message, a VIM VIM can determine the maximum number of virtual units capable of being deployed in a region and deploy virtual resources according to the reliability parameters, thereby avoiding that the VIM can deploy all virtual resources in a region in the prior art and improving the reliability of resource deployment.

Optionally, the changing unit 13 is specifically configured to query whether a preset switch item in the descriptor is turned on, where the switch item is used to indicate whether to allow the management node to change the reliability parameter; and if the switch item is opened, changing the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit.

Optionally, the resource deployment response message received by the receiving unit 11 is used to indicate that the request of the first resource deployment request message fails, where the resource deployment response message carries the changed reliability parameter, and the management unit further includes a determining unit 14.
