detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in Figure 1, it is a block diagram of an NFV system. The NFV system includes: network function virtualization scheduling node (English: network function virtualization orchestrator, abbreviation: NFVO), virtual network function management node (English: virtualized network function manager, VNFM), virtual machine infrastructure management node (English: virtualized Infrastructure manager, abbreviation: VIM), operation support system (English: operations support system, abbreviation: OSS) or business support system (English: business support system, abbreviation: BSS), network element management node (English: element manager, abbreviation: EM), VNF, virtual network functional infrastructure (English: network function virtualization infrastructure, abbreviation: NFVI), network Network service (English: network service, abbreviation: NS) directory, and VNF directory.

In the NFV system, NFVO, VNFM, and VIM form the NFV management and orchestration (NFV-MANO) domain. Among them, NFVO can also be called network function virtualization orchestrator, OSS/BSS. They can all be called network management nodes (English: network manager, abbreviation: NM).

The EM performs function configuration, fault management, function usage record, performance statistics, and security management for one or more VNFs.

The VNF is a virtualized logical network element, such as SGSN, MME, GGSN, SGW, and PGW in the telecom packet field. Each network element can be deployed independently and presented as a VNF.

NFVI provides hardware resources and virtualization resources and management for VNF, as well as virtualized runtime environments.

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

VNFM is responsible for the lifecycle management of VNF, and each VNF has an associated VNFM. A VNFM may manage one VNF, or it may manage multiple VNFs of the same type or even different types.

The NS directory stores the network service descriptor (English: network service descriptor, abbreviated: NSD), which is a template for describing the deployment and maintenance behavior of the NS, including the service topology and the characteristics of the NS. The service topology includes the components of the VNF. Partial and mutual relationship, virtual link (English: virtual links, abbreviated: VL), and VNF forwarding graph (English: VNF forwarding graph, abbreviation: VNFFG), etc., can be read by NFVO. NFVO usually performs virtual resource deployment and maintenance operations on the NS according to the VSD.

The VNF directory stores VNF descriptors (English: VNF descriptor, abbreviated: VNFD), software images, files, etc., where VNFD is a template describing VNF deployment and maintenance behavior, which can be read by VNFM or NFVO. VNFM or NFVO usually performs virtual resource deployment and maintenance operations on VNF according to VNFD.

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

In order to facilitate the understanding of the method flow in the embodiment of the present invention, the following keywords are further explained:

The virtual unit is a basic unit in the deployment process of the virtual resource. For example, when instantiating the VNF, multiple VMs constituting the VNF need to be deployed, and each of the multiple VMs is a virtual unit; When the NS is implemented, a plurality of VNFs constituting the NS need to be deployed, and each of the plurality of VNFs is a virtual unit.

A zone is a range of areas where reliability is limited during the deployment of virtual resources. For example, for VNF, an area can refer to a host (English: host), or a cabinet (English: shelve). For NS, an area can refer to the scope of a suburb, the scope of a city, etc. Geographical area.

The reliability parameter is specifically expressed as the maximum number of virtual units allowed to be deployed in an area during the deployment of the virtual resource. It can be understood that the smaller the number of virtual units allowed to be deployed in one area, the virtual The reliability of the NS or VNF composed of resources is higher.

It should be noted that any one of the foregoing NFV systems may be distributed on one physical device or may be distributed on multiple physical devices. Multiple functional nodes in the NFV system may be distributed on different physical devices. It may also be distributed on the same physical device. It can be understood that any functional node in the NFV system may be a logical functional module within the physical device, or may be a logical functional module composed of multiple physical devices.

Therefore, in the embodiment of the present invention, each step in the method provided by the embodiment of the present invention may be performed by an entity device, and the steps in the method provided by the embodiment of the present invention may be performed by multiple physical devices. The invention is not limited.

Further, in order to more clearly introduce the deployment method of the virtual resource provided by the present invention, the following is a logical function module (ie, a function node in the NFV system). The main body or control object is described. Those skilled in the art should understand that the logical function module depends on the hardware resources on the physical device where it is implemented.

In the embodiment of the present invention, the NFV system can be applied to a long term evolution (English: long term evolution, abbreviation: LTE) communication system, and can also be applied to an LTE evolved communication system, such as LTE-A (English full name: long term In the evolution advanced system, it can also be applied to third-generation mobile communication (English: 3rd-Generation, 3G) system such as WCDMA, and the present invention is not limited.

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 to distinguish different description objects, and are not to be construed as indicating or implying relative importance. Sexually or implicitly indicates the number of technical features indicated.

The embodiment of the invention provides a method for deploying a virtual resource. As shown in FIG. 2, the method may include:

S101. The management node sends a first resource deployment request message to the VIM, where the first resource deployment request message is used to request the VIM to deploy the virtual resource to be deployed, where the virtual resource includes at least one virtual unit, where the first resource deployment request message is carried. A reliability parameter corresponding to the virtual resource.

The reliability parameter is used to characterize the maximum number of virtual units allowed to be deployed in an area.

It should be noted that, in the embodiment of the present invention, the expression 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 level.

Specifically, values such as 1, 2, and 5 can represent absolute parameters. Taking absolute parameter 2 as an example, it can be characterized that up to 2 virtual units can be deployed in the same area. For example, when instantiating a VNF, a host has the most When deploying two VMs that make up the VNF, when instantiating an NS, a maximum of two VNFs that make up the NS are deployed in a suburban area.

The values of 10%, 20%, 30%, etc. can represent relative parameters, and take 20% of the relative parameters as an example to characterize a virtual unit that can deploy up to 20% of the number of virtual units in one area. For example, the number of VMs that make up a VNF is 10, when instantiating the At VNF, deploy up to 10*20%=2 VMs on a single host.

The values of 1/2, 1/3, 2/5, etc. can represent the scale. Taking the ratio 1/3 as an example, a virtual unit that can deploy up to 1/3 of the number of virtual units in one area can be represented. For example, the number of VNFs that make up an NS is 8. When the NS is instantiated, a maximum of 2 VNFs (8*1/3 integers) are deployed on one host.

Optionally, the reliability may be divided into multiple levels. For example, the reliability may be divided into the highest, the highest, the medium, the low, and the lowest five levels, and the corresponding reliability parameters are 0%, 25%, respectively. 50%, 75%, and 100%.

It should be noted that the network maintenance personnel may set corresponding reliability parameters in each descriptor according to the deployment situation of the network pre-plan, 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 may be obtained from the descriptor corresponding to the virtual resource, so that the reliability parameter is carried in the first resource deployment request message and sent to the VIM for sending.

Specifically, the reliability parameter may be set in any module in the VNFD, for example, a deployment description template of the VNF module (English: virtualised development unit, abbreviated: VDU), internal virtual link descriptor (English: internal virtual link descriptor, abbreviation: IVLD) Or IVL descriptor (English: IVL descriptor, abbreviation: IVLD) and so on.

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

The reliability parameters can also be set in any module in the NSD, such as VL or VNFFG.

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

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

When the management node is VNFM, the descriptor can be VNFD, and VNFM can pass. The information in the VNFD is obtained to deploy and maintain virtual resources of the VNF.

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

S103. The VIM determines, according to the reliability parameter, the quantity of the at least one area managed by the VIM, and the quantity of the at least one virtual unit, the request result of the first resource deployment request message, where the request result includes the first resource deployment. The request for the message was successful or failed.

It should be noted that the request for the first resource deployment request message succeeds that the VIM successfully performs resource deployment according to the reliability parameter carried in the first resource deployment request message. The request for the first resource deployment request message fails, and the VIM cannot perform resource deployment according to the reliability parameter.

Specifically, the foregoing S103 may specifically include:

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

If the VIM determines that the number of the at least one area does not satisfy the reliability parameter, the VIM determines that the request for the first resource deployment request message fails.

If the VIM determines that the number of the at least one area satisfies the reliability parameter, the VIM determines that the request for the first resource deployment request message is successful.

Exemplarily, in order to better explain that the VIM determines, according to the number of the at least one virtual unit, the quantity of the at least one area, and the reliability parameter, whether the quantity of the at least one area satisfies the reliability parameter, One virtual unit is 8 VMs, and the reliability parameter is 2 as an example for exemplary explanation.

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

Assume that at least one area managed by the VIM is three hosts. Since the eight VMs are deployed on three hosts, at least one host needs to deploy more than two VMs, so the reliability parameters are not met. 2, and according to reliability parameter 2, deploying 8 VMs requires at least 4 hosts. Since 3 is less than 4, VIM determines its management. The number of hosts does not meet the reliability parameter, and the VIM determines that the request for the first resource deployment request message fails. That is, the VIM determines that the eight VMs cannot be successfully deployed on three stations according to the reliability parameter.

Assume that at least one area 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 the VIM determines that the request for the first resource deployment request message is successful. That is, the VIM determines that the eight VMs can be successfully deployed on the five hosts according to the reliability parameter.

S104. The VIM sends a resource deployment response message to the management node according to the result of the request, where the resource deployment response message is used to indicate that the request of the first resource deployment request message succeeds or fails.

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

In the embodiment of the present invention, when the management node requests the resource deployment from the VIM, 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 resource according to the reliability parameter. The maximum number of virtual units that VIM is allowed to deploy in an area is limited, so that the VIM in the prior art may deploy all the virtual resources in one area, thereby improving the reliability of resource deployment.

Further, on the one hand, in the case that the request of the first resource deployment request message fails, the management node and the VIM can perform the following two subsequent operations.

(1) If the VIM determines that the request for the first resource deployment request message fails, the resource deployment response message is used to indicate that the request for the first resource deployment request message fails, and the resource deployment response message carries at least the VIM managed by the VIM. The number of one area, the number of the at least one area is used by the management node to change the reliability parameter, so that the changed reliability parameter satisfies the number of areas managed by the VIM.

Specifically, if the VIM determines that the request for the first resource deployment request message fails, as shown in FIG. 3, as shown in FIG. 3, after the foregoing S105, the method further includes:

S106. The management node changes the reliability parameter according to the number of the at least one area and the quantity of the at least one virtual unit, and the modified reliability parameter satisfies the quantity of the at least one area.

Exemplarily, it is assumed that the at least one virtual unit includes 8 VMs, and the at least one area includes 3 hosts. After receiving the resource deployment response message sent by the VIM, the management node determines that the request for the first resource deployment request message fails, and determines that the host managed by the VIM has a total of three hosts, and the management node can determine that 8 hosts can be successfully deployed on the three hosts. The deployment plan of the VM may include "008" and "017", respectively, indicating that eight VMs are deployed on the same host of the three hosts, and one VM is deployed on one of the three hosts. The other seven VMs are deployed on the other of the three hosts. By analogy, the deployment plan that the management node can determine includes "026", "035", "044", "116", "125", "134", "224", and "233".

Since the maximum number of virtual units allowed to be deployed in an area is less, the reliability is higher. Therefore, the management node can determine the deployment plan with the fewest virtual units deployed on one area, that is, "233" is the 10 deployment plans. The most reliable deployment solution. The maximum number of virtual cells deployed in an area is 3, that is, the reliability parameter corresponding to the deployment plan is 3. Therefore, the management node can set the reliability parameters from the original 2 Change to 3. The changed 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, where the second resource deployment request message carries the changed reliability parameter.

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 can be reliable according to the actual physical resource, that is, the number of at least one area managed by the VIM. The parameter is changed and changed to a parameter that satisfies the quantity of the at least one area, and the changed reliability parameter is carried in the second resource deployment request message and sent to the VIM to request the VIM again according to the reliability of the change. The sexual parameters are deployed for the deployed virtual resources. After the changed reliability parameter satisfies the quantity of the at least one area, the VIM can successfully deploy the virtual resource on the at least one area according to the changed reliability parameter after the VIM receives the second resource deployment request message.

It can be understood that, in the method for deploying the virtual resource provided by the embodiment of the present invention, since the preset reliability parameter has adjustability, it can be in the area managed by the VIM. When the number of the reliability parameters does not meet the preset reliability parameters, the reliability is changed to ensure that the virtual resources can be successfully deployed in the area, and the reliability of the virtual resource deployment is ensured, thereby improving the flexibility of virtual resource deployment.

Optionally, in a practical application, there is a possible application scenario, that is, according to actual engineering requirements, in the process of deploying virtual resources, resource deployment must be strictly performed according to preset reliability parameters, that is, no change is allowed. Reliability parameters. 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 enabled, the representation allows the management node to change the reliability parameter; if the switch item is closed, the representation does not allow the management node to change the reliability parameter.

Exemplarily, the switch item can be a flag bit. If the flag bit is set to 1, it indicates that the switch item is turned on. If the flag bit is set to 0, the switch item is turned off; or the string off and on can be used to represent The switch item is closed and opened, and the embodiment of the present invention is not limited thereto.

Further, before the management node changes the reliability parameter according to the quantity of the at least one area and the quantity of the at least one virtual unit, the management node may first query whether the preset switch item in the descriptor storing the reliability parameter is turned on, if The switch item is turned on, and the management node can 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 change the reliability parameter. In this case, the management node may notify the network maintenance personnel that the request for the first resource deployment request message fails, and notify the network maintenance personnel of the number of the at least one area. Therefore, the network maintenance personnel can know that the number of areas managed by the VIM is insufficient, and the network maintenance personnel can increase the deployment of physical resources, so that the physical resources can meet the requirements of deploying the virtual resources to be deployed, thereby enabling the virtual resources to be deployed. Successful deployment according to the required reliability parameters.

(2) If the request for the first resource deployment request message fails, the resource deployment response message is used to indicate that the request for the first resource deployment request message fails.

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

S1. The VIM is based on the number of the at least one area and the at least one virtual unit. The quantity, the reliability parameter is changed, and the modified reliability parameter satisfies the number of the at least one area.

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

Specifically, the specific method for the VIM to change the reliability parameter according to the number of the at least one area and the number of the at least one virtual unit, as described in the above S106, the management node according to the quantity of the at least one area and the at least one virtual unit The number, the specific method of changing the reliability parameter, will not be described here.

Further, after the VIM determines the modified reliability parameter, the changed reliability parameter may be carried in the resource deployment response message and sent to the management node to query whether the management node can use the reliability after the change. Sexual parameters.

Further, after the foregoing S105, the method further includes:

S2. The management node determines whether the modified reliability parameter is allowed to be used.

Exemplarily, the management node may query whether the switch item in the descriptor of the reliability parameter is enabled, and if the switch item is enabled, the management node determines that the modified reliability parameter is allowed to be used; if the switch item is closed, The management node determines that the changed reliability parameters are not allowed.

The management node may also prompt the network maintenance personnel to prompt the modified reliability parameter sent by the VIM, and determine whether the modified reliability parameter is allowed according to the instruction of the network maintenance personnel.

It should be noted that, the manner in which the management node determines whether the modified reliability parameter is allowed to be used may be set more in actual engineering, and the present invention is not limited.

S3. The management node sends a change response message to the VIM, where the change response message is used to indicate whether the modified reliability parameter is allowed to be used.

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

S5. If the change response message is used to indicate 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 for the first resource deployment request message is successful, the VIM is at least You can deploy virtual resources according to reliability parameters in the following two ways.

In the first method, as shown in FIG. 4, before the foregoing S104, the method further includes:

S108. The VIM determines, according to the quantity of the at least one virtual unit and the at least one area, at least one deployment scheme that satisfies the reliability parameter and is allowed by the VIM.

Exemplarily, the reliability parameter is 4, 8 VMs and 3 hosts as an example.

According to reliability parameter 4, VIM determines all deployment scenarios for successfully deploying 8 VMs on 3 hosts. All deployment scenarios allowed by the VIM include "044", "134", "224", and "233". The deployment scenario "233" is the most reliable deployment solution among all the deployment scenarios allowed by the VIM, because the deployment scenario "233" is a deployment scenario in which the deployment of the VM is minimal on one of the deployment scenarios.

After the VIM determines that the reliability parameter is met and all the deployment scenarios are allowed by the VIM, the VIM can carry the at least one deployment scenario of all the deployment scenarios to the management node in the resource deployment response message.

It should be noted that the at least one deployment solution may include all deployment scenarios allowed by the VIM, that is, the VIM may carry all the deployment scenarios allowed by the VIM in a resource deployment response message to the management node to request the management node to Choose one of all deployment scenarios allowed by the VIM.

The at least one deployment solution may include the most reliable deployment solution among all the deployment scenarios allowed by the VIM, that is, the VIM can select the most reliable deployment solution among all the deployment scenarios allowed by the VIM, and then the reliability is the highest. The deployment solution is sent to the management node in the resource deployment response message to query whether the management node can perform resource deployment according to the most reliable deployment scenario.

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

S109. The management node determines the first deployment scenario from the at least one deployment scenario.

That is, after the management node receives the resource deployment response message, determines that the request for the first resource deployment request message is successful, and obtains at least one deployment scenario allowed by the VIM from the resource deployment response message, the management node may obtain the at least one A deployment scenario is randomly selected as the first deployment scenario, and the at least one deployment may also be selected. A deployment solution with the highest reliability in the solution is the first deployment solution, and the present invention is not specifically limited.

S110. The management node sends a resource deployment indication message to the VIM, where the resource deployment indication message carries the first deployment solution.

After the management node determines the first deployment solution from the at least one deployment scenario, the first deployment solution may be sent to the VIM in the resource deployment indication message to indicate that the VIM deploys the virtual resource according to the first deployment scenario.

S111. The VIM receives a resource deployment indication message sent by the management node.

S112. The VIM deploys the virtual resource on the at least one area according to the first deployment scenario.

Exemplarily, in combination with the example in S107 above, assuming that the first deployment scenario is “233”, the VIM can deploy two VMs on one of the three hosts, and the other two hosts respectively deploy three. VM.

In the second method, as shown in FIG. 2, before the foregoing S104, the method further includes:

S113. The VIM determines the first deployment scenario from the at least one deployment scenario according to the deployment scenario 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 includes a deployment plan selection rule, where the deployment plan selection rule is used by the VIM to determine the first deployment plan from the at least one deployment solution. .

Exemplarily, the deployment scenario selection rule may be to select the most reliable deployment scenario from at least one deployment scenario. For example, as in the example in the embodiment shown in FIG. 4, the deployment scenario "233" is selected. The deployment plan selection rule may also be a deployment plan with the least number of required areas. For example, as shown in the example in the embodiment shown in FIG. 4, the deployment plan "044" is selected, in which only two hosts are needed. According to the requirements of reliability parameter 4, 8 VMs were successfully deployed.

S114. The VIM deploys the virtual resource on at least one area according to the first deployment plan. source.

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

It should be noted that the virtual resource deployment method provided by the present invention can be applied to various application scenarios, such as instantiation of VNF, instantiation of NS, extension process of VNF, extension of NS, migration of VNF, and NS. Scenarios such as migration, which include the deployment process of virtual resources.

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

Further, if the deployment of the virtual resource specifically refers to the 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 to request the VIM to allocate the virtual resource; The deployment of the virtual resource specifically refers to the reservation of the virtual resource, and the first resource deployment request message is specifically a first resource reservation request message, and the first resource reservation request message is used to request the VIM to reserve the virtual resource; The deployment of the virtual resource specifically refers to the migration of the virtual resource, and the first resource deployment request message is specifically a first resource migration request message, and the first resource migration request message is used to request the VIM to migrate the virtual resource to the VIM management. At least one area.

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

In particular, when the management node is a VNFM, the VNFM may have the function of changing the reliability parameter, so that when the request for the first resource allocation request message fails, the VNFM may change the reliability parameter by itself. Of course, the VNFM may also not have the 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 request of the VNFM, and before the modification of the reliability parameter, first queries whether the switch item is turned on, and responds to the request of the VNFM when the switch type is turned on. , modify the reliability parameters.

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

S201. The VNFM sends a first resource allocation request message to the VIM, where the first resource allocation request message carries a reliability parameter.

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

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

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 for the first resource allocation request message fails, and the resource deployment response message carries the quantity of the at least one area.

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

S206. The VNFM sends the number of the at least one area and the quantity of the at least one virtual unit to the NFVO.

The VNFM may send the number of the at least one area and the number of the at least one virtual unit to the NFVO in a message for information transmission between the VNFM and the VNFO.

S207. The NFVO changes the reliability parameter according to the number of the at least one area and the quantity of the at least one virtual unit.

S208. The NFVO sends the modified reliability parameter to the VNFM.

S209. After receiving the changed 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 changed reliability parameter.

Further, when the VIM receives the second resource allocation request message, it can follow the change. After the reliability parameters are deployed for virtual resources. It can be understood that, because the modified reliability parameter satisfies the number of areas managed by the VIM, the VIM can successfully deploy the virtual resource according to the modified reliability parameter.

The embodiment of the present invention provides a method for deploying a virtual resource, where the management node can carry the reliability parameter in the first resource deployment request message, because the reliability parameter represents the maximum number of virtual units allowed to be deployed in an area, After receiving the first resource deployment request message, the VIM VIM can determine the maximum number of virtual cells that can be deployed in an area, and deploy the virtual resources according to the reliability parameter, thereby avoiding the VIM in the prior art.
