Description

Virtual resource management method, virtual resource management equipment and server

Technical Field

The present application relates to the field of communications, and in particular, to a virtual resource management method, a virtual resource management device, and a server.

Background

Network Function Virtualization (NFV) technology can migrate The functions of each Network element used in a communication Network from a current dedicated hardware platform to a common Commercial Off-The-Shelf (COTS) server. In the NFV scenario, a Virtual Network Function (VNF) is deployed and installed through a Virtual Network Function Manager (Virtual Network Function Manager, VNFM) by using an initially issued Virtual Network Function module Descriptor (VNFD) file, and includes Virtual resource information of a plurality of VNFs, where the Virtual resource information may specifically be specification, number, Network connection, and the like of a Virtual Machine (Virtual Machine, VM).

In the NFV scenario, when a Data Center (DC) suffers from a DC fault caused by a natural disaster such as an earthquake, a flood, etc., virtual resources of VNFs deployed by a VNFM will all fail, and after the DC fault is recovered, the VNFM deploys and installs the VNFs again using initially published VNFD files.

However, because the VNFM does not have the capability of dynamically refreshing the VNFD file, when the virtual resource of the VNF changes due to operations such as flexible scaling, capacity expansion, or upgrading before the DC fails, the VNFM cannot update the changed virtual resource information of the VNF to the VNFD file, and after the DC failure is recovered, only the initially issued VNFD file can be used to relocate and install the VNF and the virtual resource of the VNF, so that the virtual resource of the VNF after the DC failure is recovered is inconsistent with the virtual resource of the VNF before the DC failure.

Each network element used in the telecommunication network is converted into independent application through NFV technology, the network element can be flexibly deployed on a unified infrastructure platform constructed by other equipment such as a standard server, a storage and a switch, the resources of infrastructure hardware equipment are pooled and virtualized through virtualization technology, virtual resources are provided for upper-layer application, application and hardware decoupling is achieved, each application can rapidly increase the virtual resources to achieve the purpose of rapidly expanding the system capacity, or the virtual resources can be rapidly reduced to achieve the purpose of shrinking the system capacity, and the elasticity of the network is greatly improved. A shared resource pool is formed by adopting a universal COTS server, newly developed services do not need to be independently deployed with hardware equipment, and the online time of the new services is greatly shortened.

The foundation of NFV technology includes cloud computing technology and virtualization technology. Hardware devices such as a general COTS (chip on the fly) calculation/storage/network and the like can be decomposed into a plurality of virtual resources through a virtualization technology so as to be used by various upper-layer applications. The decoupling between the application and the hardware is realized through a virtualization technology, so that the virtual resource supply speed is greatly increased; by the cloud computing technology, elastic expansion of application can be achieved, matching of virtual resources and service loads is achieved, utilization efficiency of the virtual resources is improved, and response rate of a system is improved.

Fig. 1 is a schematic diagram of an NFV architecture system, and the NFV architecture system 100 may be implemented in various networks, such as a data center network, an operator network, or a local area network. The NFV architecture System 100 includes an NFV Management and Orchestration System (NFV MANO)101, an NFV Infrastructure layer (NFV Infrastructure, NFVI)130, a plurality of VNFs 108, a plurality of Element Management (EM) 122, Network services, VNFs, and Infrastructure Description (Network Service) 126, and an Operation-Support Management System (OSS/BSS). Among other things, NFV MANO101 includes NFV Orchestrator (NFV editor, NFVO)102, one or more VNFMs 104, and Virtualization Infrastructure Manager (VIM) 106. NFVI130 includes computing hardware 112, storage hardware 114, network hardware 116, virtualization layers, virtual compute 110, virtual storage 118, and virtual network 120. Network services, VNF and infrastructure description 126 and OSS/BSS 124 are discussed further in the ETSI GS NFV 002V1.1.1 standard.

The NFV MANO101 is used to perform monitoring and management of VNF108 and NFVI 130. NFVO102 may implement network services (e.g., L2 and L3VPN services) on NFVI130, and may also perform resource-related requests from one or more VNFMs 104, send configuration information to VNFMs 104, and collect VNF108 state information. Additionally, NFVO102 may communicate with VIM106 to enable allocation and/or reservation of resources and exchange configuration and status information for virtualized hardware resources. The VNFM104 may manage one or more VNFs 108. The VNFM104 may perform various management functions such as instantiating, updating, querying, scaling, and/or terminating the VNF108, among others. VIM106 may perform functions for resource management, such as managing allocation of infrastructure resources (e.g., adding resources to virtual containers) and operational functions (e.g., collecting NFVI fault information). The VNFM104 and VIM106 may communicate with each other for resource allocation and exchange configuration and status information for virtualized hardware resources.

NFVI130 includes hardware resources, software resources, or a combination of both to complete the deployment of the virtualized environment. In other words, the hardware resources and virtualization layer are used to provide virtualized resources, e.g., as virtual machines and other forms of virtual containers, for VNF 108. The hardware resources include computing hardware 112, storage hardware 114, and network hardware 116. The computing hardware 112 may be commercially available hardware and/or custom hardware to provide processing and computing resources. The storage hardware 114 may be storage capacity provided within a network or storage capacity residing within the storage hardware 114 itself (local storage located within a server). In one implementation, the resources of the computing hardware 112 and the storage hardware 114 may be pooled together. The network hardware 116 may be a switch, a router, and/or any other network device configured with switching functionality. The network hardware 116 may span multiple domains and may include multiple networks interconnected by one or more transport networks.

A virtualization layer within NFVI130 may abstract hardware resources from the physical layer and decouple VNF108 to provide virtualized resources to VNF 108. The virtual resource layer includes virtual compute 110, virtual memory 118, and virtual network 120. Virtual compute 110 and virtual storage 118 may be provided to VNF108 in the form of virtual machines, and/or other virtual containers. For example, one or more VNFs 108 may be deployed on one Virtual Machine (Virtual Machine). The virtualization layer abstracts the network hardware 116 to form a Virtual network 120, and the Virtual network 120 may include Virtual switches (Virtual switches) that are used to provide connectivity between Virtual machines and other Virtual machines. In addition, the transport Network in the Network hardware 116 may be virtualized using a centralized control plane and a separate forwarding plane (e.g., Software Defined Network (SDN)).

As shown in fig. 1, VNFM104 may interact with VNF108 and EM122 to manage the VNF's lifecycle and exchange configuration and status information. VNF108 may be configured to virtualize at least one network function performed by one physical network device. For example, in one implementation, VNF108 may be configured to provide functionality provided by different network elements in the IMS network, such as network functionality of a P-SCSCF, S-CSCF, or HSS, among others. EM122 is configured to manage one or more VNFs 108.

As shown in fig. 1, in the NFV system architecture, a distributed VNF is adopted, and virtualized resources of a virtual computing 110, a virtual storage 118, and a virtual network 120 are provided to a VNF108 in a virtual machine form, and when the VNF108 needs a service, the virtualized resources in the virtual machine are expanded or reduced, that is, a specification of the virtual machine is adjusted in a vertical capacity expansion manner. The existing method is to adopt a mode of expanding the specification of a VNF service virtual machine to improve the specification capability of the VNF, or a mode of reducing the specification of the VNF service virtual machine to reduce the specification capability of the VNF, so that all virtual machines participating in expansion and reduction need to be subjected to expansion and reduction processing, during the expansion and reduction processing, the virtual machines need to be powered off first, and then the virtual machines are powered on after expansion and reduction, so that ongoing services need to be interrupted, and the service progress is influenced.

It should be noted that, in the embodiment of the present application, the VNF is referred to as a virtual service network element, and the VNFM is referred to as a virtual resource management device.

In a current NFV scenario, when a DC is subjected to a natural disaster such as an earthquake and a flood, and a DC fault is caused, virtual resources of VNFs deployed by VNFMs all fail, after the DC fault is recovered, the VNFMs use initially issued VNFD files to relocate and install the VNFs, and the initially issued VNFD files include deployment blueprints and resource deployment profiles (dediymentfiavours, DFs) of each VNF, and the DFs reflect virtual resources of the VNFs, so that virtual resource information of the VNFs deployed and installed by using the initially issued VNFD files is necessarily consistent with the initial DFs, and if before the VNFs are relocated and installed, the virtual resources before and after the VNFs are inconsistent when operations such as elastic expansion, or upgrade of the VNFs occur.

In order to solve the problem of inconsistency of virtual resources before and after the VNF is redeployed, in the current solution, the following solutions are involved in different scenarios: 1. before redeploying the VNF, the VNF carries out capacity expansion and reduction operation and records capacity expansion and reduction DF of the capacity expansion and reduction operation, so that when the VNF is redeployed, initial DF deployment of an initially issued VNFD file is firstly used for obtaining initial virtual resources of the VNF, and then capacity expansion and reduction transformation are carried out by using the capacity expansion and reduction DF; 2. for the flexible scaling operation of the VNF, a flexible scaling DF may not be generated, so that when the VNF is redeployed, the VNF can only be redeployed through the initially published VNFD file, and for the flexible scaling operation before the redeployment of the VNF, the redeployment of the VNF cannot be performed, which inevitably results in inconsistency of virtual resources before and after the redeployment of the VNF; 3. before redeploying the VNF, the VNF is upgraded, the VNF FD file is upgraded to a high version in the upgrading process of the VNF, and when the VNF is redeployed, the VNF is deployed by using the VNFD file of the high version, however, if the expansion and contraction or elastic expansion and contraction operation is performed before the VNF is upgraded, the VNFD file of the high version is not stored for the expansion and contraction or elastic expansion and contraction operation, which inevitably causes inconsistency of virtual resources before and after the VNF is redeployed.

As can be seen from the above description, the consistency of the virtual resources before and after the redeployment of the VNF cannot be guaranteed, so to solve the problem, in the following embodiment, an entity device corresponding to the virtual resource management device of the present application is introduced first, where the entity device takes a server as an example, and in the embodiment of the present application, the VNF is referred to as a virtual service network element, the VNFM is referred to as a virtual resource management device, and the VNFD file is referred to as network element configuration information.

Referring to fig. 2, an embodiment of the present application provides a server, including:

a processor 201, a transceiver 202, and a memory 203, wherein the memory 203 may be used to store code executed by the processor 201;

the processor 201, the transceiver 202 and the memory 203 are connected by a bus system;

the transceiver 202 is configured to obtain current virtual resource information of virtual service network elements, where the current virtual resource information is used to represent current virtual resources of the virtual service network elements, and there is at least one virtual service network element;

a processor 201, configured to generate backup network element configuration information of a virtual service network element according to current virtual resource information, where the backup network element configuration information is used to deploy the virtual service network element; (ii) a

The processor 201 is further configured to, when the virtual service network element needs to be redeployed, deploy according to the backup network element configuration information to obtain a target virtual service network element, where a virtual resource of the target virtual service network element is the same as a current virtual resource of the virtual service network element.

In the embodiment of the present application, the virtual service network element is deployed by the virtual resource management device using the initially issued network element configuration information, the virtual resource of the virtual service network element is also configured by the virtual resource management device according to the initially issued network element configuration information, and in an NFV scenario, in order to adjust the service processing capability of the virtual network system and reasonably allocate the virtual resource, during the period when the virtual resource management device performs lifecycle management on the virtual service network element, the virtual service network element may perform operations such as expansion and contraction, elastic expansion and upgrade, which will change the virtual resource of the virtual service network element, and after each virtual resource change, the database of the virtual resource management device performs corresponding records, so that the transceiver 202 can obtain the current virtual resource information of all virtual service network elements from the database, since the current virtual resource information of the virtual service network element reflects the virtual resource in the current state of the virtual service network element, if the virtual service network element with the virtual resource in the current state needs to be redeployed, the use of the initially released network element configuration information cannot be done, because the initially released network element configuration information is used to redeploye the obtained virtual service network element, the virtual resource of the virtual service network element is necessarily inconsistent with the current virtual resource of the virtual resource change, the processor 201 generates the backup network element configuration information of the virtual service network element according to the current virtual resource information acquired by the transceiver 202, when the virtual service network element needs to be redeployed, the processor 201 deploys the target virtual service network element according to the configuration information of the backup network element, since the backup network element configuration information is generated according to the current virtual resource information, the virtual resources of the target virtual service network element are the same as the current virtual resources of the virtual service network element.

In the embodiment shown in fig. 2, an entity device corresponding to the virtual resource management device is described, where the entity device takes a server as an example, and a management method applied to virtual resources in the server is described below by using the embodiment.

Referring to fig. 3, an embodiment of the present application provides a method for managing virtual resources, including:

301. the virtual resource management equipment acquires the current virtual resource information of the virtual service network element;

in this embodiment, the virtual service network element is obtained by the virtual resource management device using the initially issued network element configuration information for deployment, and the virtual resource of the virtual service network element is also configured by the virtual resource management device according to the initially issued network element configuration information, in the NFV scenario, in order to adjust the service processing capability of the virtual network system, and reasonably allocate virtual resources, during the period that the virtual resource management device manages the life cycle of the virtual service network element, the virtual service network element can perform operations such as capacity expansion, elastic expansion, upgrading and the like, these operations change the virtual resources of the virtual service network element, and after each virtual resource change, corresponding records are recorded in the database of the virtual resource management device, so that the virtual resource management device can obtain the current virtual resource information of all virtual service network elements through the database.

302. The virtual resource management equipment generates backup network element configuration information of the virtual service network element according to the current virtual resource information;

in this embodiment, since the current virtual resource information of the virtual service network element reflects the virtual resource of the virtual service network element in the current state, if the virtual resource management device needs to be redeployed to obtain the virtual service network element with the virtual resource in the current state, it is impossible to use the initially issued network element configuration information, because the virtual resource of the virtual service network element obtained by redeploying the initially issued network element configuration information is inevitably inconsistent with the current virtual resource of the virtual resource change, the backup network element configuration information of the virtual service network element needs to be generated according to the current virtual resource information.

303. When the virtual service network element needs to be redeployed, the virtual resource management equipment deploys according to the backup network element configuration information to obtain a target virtual service network element.

In this embodiment, when a DC-level disaster occurs to a DC to which the virtual resource management device belongs, a DC fault may cause that all virtual service network elements managed by the virtual resource management device cannot provide services, and after the DC fault is recovered, the virtual resource management device needs to relocate the virtual service network elements at this time in order to recover the service capability of the virtual service network elements; or, a single virtual service network element fails to provide a service due to performance and other problems, and the virtual resource management device needs to relocate the virtual service network element at this time. When the virtual service network element needs to be redeployed, the virtual resource management device deploys according to the backup network element configuration information to obtain a target virtual service network element, and since the backup network element configuration information is generated according to the current virtual resource information, the virtual resource of the target virtual service network element is the same as the current virtual resource of the virtual service network element.

In the embodiment of the application, the virtual resource management device obtains the backup network element configuration information according to the current virtual resource information of the virtual service network element, when the virtual service network element needs to be redeployed, the target virtual service network element is redeployed according to the backup network element configuration information, and compared with the method for redeploying the virtual service network element by using the initially issued network element configuration information, the virtual resource of the target virtual service network element obtained by redeployment can be ensured to be consistent with the current virtual resource of the virtual service network element before redeployment even if the virtual resource of the virtual service network element changes in the period from the completion of the initial deployment to the redeployment.

It should be noted that the backup network element configuration information may be generated by a virtual resource management device initiated by a user and instructed to be generated, or a periodic automatic generation mechanism is preset in the virtual resource management device, and after the backup network element configuration information is generated, the backup network element configuration information may be exported by the user for backup, or the backup network element configuration information may be sent to a disaster recovery device, and when a virtual service network element needs to be redeployed, the user may import the backup network element configuration information to the virtual resource management device, or the disaster recovery device redeployes the virtual service network element using the backup network element configuration information.

In the embodiment shown in fig. 1, the network element configuration information is specifically a VNFD file, where the VNFD file is a configuration template of deployment and operation behaviors of one or more virtual service network elements (i.e., VNFs). The VNFD file comprises a blueprint template, a DF (dynamic function definition) and an operation script and the like, wherein the blueprint template specifically relates to the planning and the like of network resources when the VNF is deployed; DF is an overview of the virtual resources of the VNF, and the virtual resource information of the VNF may specifically be information such as the specification, number, and network connection of the VM; the running script is mainly used for performing operations such as deployment and maintenance on the VNF.

Optionally, in some embodiments of the present application, generating backup network element configuration information of a virtual service network element according to current virtual resource information includes:

acquiring initial network element configuration information of a virtual service network element, wherein the initial network element configuration information comprises initial deployment profile information, and the initial deployment profile information is used for representing initial virtual resources of the virtual service network element;

when the current virtual resource information is different from the initial deployment profile information, generating backup deployment profile information according to the current virtual resource information and the initial deployment profile information;

and generating backup network element configuration information according to the backup deployment profile information.

In this embodiment, a virtual service network element (VNF) is deployed by a virtual resource management device using initially issued network element configuration information (an initial VNFD file), a virtual resource of the virtual service network element is described by initial deployment profile information (initial DF) in the initial VNFD, and the initial DF in the initial VNFD file and current virtual resource information are both stored in a database of the virtual resource management device, so that an initial DF representing an initial virtual resource of the virtual service network element in the initial VNFD file can be obtained, the initial DF is compared with current virtual resource information, if the current virtual resource information is different from the initial DF, it indicates that the current virtual resource is different from the initial virtual resource, that is, operations such as capacity expansion, elastic scaling or upgrading are performed, a backup DF needs to be generated according to the current virtual resource information and the initial DF, and generating a backup VNFD file according to the backup DF, wherein the virtual resource management equipment uses the backup VNFD file with the backup DF and can deploy the VNF of the current virtual resource.

It should be noted that, if the current virtual resource information is the same as the initial deployment profile information, the virtual resource representing the VNF is consistent at the time of initial deployment and in the current situation, and the subsequent redeployment is not affected whether the backup DF is generated or not.

In the above-described embodiment, the virtual resource information may be described by Virtual Deployment Unit (VDU) information. VDUs are used for the construction of an information schema, which may support the deployment of subsets of VNFs and the description of the operational behavior, or the description of the entire VNF without subsets. Within the virtual machine manager (Hypervisor), the main feature of the VDU is a single VNF instance or VNF subset instance based on a construct that can be mapped to a single virtual machine VM. A Virtual Network Interface Controller (VNIC) is used to represent the virtualized network Interface controller created by the Hypervisor for the VM. Then the current virtual resource information includes VDU information for the current VDU, the initial DF includes VDU information for the initial VDU, and at least one of the current VDU and the initial VDU. With reference to fig. 4, the present application provides a method for managing virtual resources, which includes:

401. the virtual resource management equipment acquires the current virtual resource information of the virtual service network element;

in this embodiment, the virtual resource management device acquires, from the database, current virtual resource information in a current state related to the VNF, where the current virtual resource information includes VDU information of current VDUs, for example, there are 4 current VDUs, which are respectively VDU1, VDU2, VDU3, and VDU4, and the VDU information of each VDU includes a VDU identifier, a VDU specification, a VDU VNIC, and the like.

402. The virtual resource management equipment acquires initial network element configuration information of a virtual service network element;

in this embodiment, the VNF is deployed by the virtual resource management device using an initial VNFD file, where the initial VNFD file is already stored in the virtual resource management device, the initial VNFD file can be obtained, and an initial DF representing an initial virtual resource of the VNF in the initial VNFD file is obtained, where the initial DF is also represented by VDU information, for example, 3 initial VDUs are respectively a VDU1, a VDU2, and a VDU3, and the VDU information also includes a VDU identifier, a VDU specification, a VDU VNIC, and the like.

403. The virtual resource management equipment determines the number of the current virtual deployment units and the information of the virtual deployment units according to the current virtual resource information, and determines the number of the initial virtual deployment units and the information of the virtual deployment units according to the initial deployment profile information;

in this embodiment, after the virtual resource management device obtains the current virtual resource information and the initial VNFD file, the number of current VDUs and VDU information may be obtained according to the current virtual resource information, and the number of initial VDUs and VDU information may be obtained according to the initial DF in the initial VNFD file.

404. The virtual resource management device determines whether the number of the current virtual deployment units is equal to the number of the initial virtual deployment units, if so, executes step 405, and if not, executes step 407;

in this embodiment, the virtual resource management device first determines whether the number of the current VDUs is equal to the number of the initial VDUs, and if the number of the current VDUs is not equal to the number of the initial VDUs, it indicates that the virtual resources of the VNF are definitely changed, then step 407 is executed; if the number of current VDUs is equal to the number of initial VDUs, then the VDU information of each current VDU and the initial VDU needs to be further compared, and step 405 is executed.

405. The virtual resource management device compares the virtual deployment unit information of the current virtual deployment unit with the virtual deployment unit information of the corresponding initial virtual deployment unit, if the virtual deployment unit information is the same as the virtual deployment unit information, the step 406 is executed, and if the virtual deployment unit information is different from the virtual deployment unit information, the step 407 is executed;

in this embodiment, when it is determined that the number of the current VDUs is equal to the number of the initial VDUs, comparing the VDU information of the current VDU with the VDU information of the corresponding initial VDU, for example, the number of the current VDUs is 3, and the VDU identifiers in the VDU information are respectively VDU2, VDU3, and VDU 4; the number of the initial VDUs is 3, and the VDU identifiers in the VDU information are respectively VDU1, VDU2, and VDU3, which means that after the initial deployment of the VNF, operations of deleting VDU1 and adding VDU4 are performed, and it is obvious that the current virtual resource information is different from the initial DF, and step 407 is performed; if the number of the current VDUs is 3, the VDU identifications in the VDU information are respectively the VDU1, the VDU2 and the VDU 3; the number of the initial VDU is 3, and the VDU identifiers in the VDU information are respectively VDU1, VDU2 and VDU3, which indicates that the VNF does not perform operations of deleting and adding VDU after initial deployment, but the specification of the VDU1 and the VDU VNIC of the initial VDU need to be compared with the specification of the corresponding VDU1 and the VDU VNIC in the current VDU, and if all the specifications and VDU VNICs of the initial VDU and the corresponding current VDU are the same, which indicates that the current virtual resource information is the same as the initial DF, step 406 is performed.

406. The virtual resource management equipment determines that the current virtual resource information is the same as the initial deployment profile information;

in this embodiment, when it is determined that the VDU information of the current VDU is the same as the VDU information of the corresponding initial VDU, the virtual resource management device determines that the current virtual resource information is the same as the initial DF, and at this time, a backup DF does not need to be generated.

407. The virtual resource management equipment determines that the current virtual resource information is different from the initial deployment profile information;

in this embodiment, when it is determined that the number of the current VDU is not equal to the number of the initial VDU, or it is determined that the VDU information of the current VDU is different from the VDU information of the corresponding initial VDU, the virtual resource management device determines that the current virtual resource information is different from the initial DF.

408. The virtual resource management equipment obtains difference information according to the virtual deployment unit information of the current virtual deployment unit and the virtual deployment unit information of the corresponding initial virtual deployment unit, and obtains the virtual unit information of the target virtual deployment unit according to the virtual deployment unit information and the difference information of the initial virtual deployment unit;

in this embodiment, the virtual resource management device compares the virtual deployment unit information of the current virtual deployment unit with that of the corresponding initial virtual deployment unit to obtain difference information, and obtains the virtual unit information of the target virtual deployment unit according to the virtual deployment unit information of the initial virtual deployment unit and the difference information, where the number of target VDUs is at least one, for example, the number of current VDUs is 3, and VDU identifiers in the VDU information are VDU2, VDU3, and VDU4, respectively; the number of the initial VDUs is 3, the VDU identifiers in the VDU information are respectively VDU1, VDU2 and VDU3, then the target VDU is the two VDUs with the VDU identifiers of VDU1 and VDU4, the VDU information of VDU4 is obtained from the current virtual resource information, and the VDU information of VDU1 is obtained from the initial DF.

409. The virtual resource management equipment generates backup deployment general information according to the virtual deployment unit information of the target virtual deployment unit;

in this embodiment, after acquiring the VDU information of the target VDU (VDU4 and VDU1), the virtual resource management device deletes the VDU information of the VDU1 in the initial DF, adds the VDU information of the VDU4 to the initial DF, identifies the initial DF as a backup DF, and obtains the VDU information including the VDU2, the VDU3, and the VDU4 in the backup DF, so that the backup DF describes the current virtual resource of the VNF.

410. When the virtual service network element needs to be redeployed, the virtual resource management equipment deploys according to the backup network element configuration information to obtain a target virtual service network element.

In this embodiment, when the VNF needs to be redeployed, the virtual resource management device deploys the target VNF using the backup VNFD file, and since the backup DF in the backup VNFD file describes the virtual resource before redeployment of the target VNF, the virtual resource of the target VNF obtained by deployment is the same as the current virtual resource before redeployment.

In the embodiment of the application, the virtual resource management device compares VDU information of a current VDU in current virtual resource information with VDU information of an initial VDU in an initial DF, if a target VDU with VDU information difference exists, a backup DF is generated according to the VDU information of the target VDU and the initial DF, and the backup DF is stored in a backup VNFD file.

In the above embodiment, after the virtual service network element is redeployed, the virtual resources are theoretically consistent with those before deployment, but during the deployment, there may be deployment errors, and then resource check is required, which is described below by an embodiment.

Optionally, referring to fig. 5, in some embodiments of the present application, after the target virtual service network element is deployed according to the configuration information of the backup network element, the method further includes:

501. the virtual resource management equipment sends the resource checking information to a target virtual service network element;

in this embodiment, when a virtual resource management device (VNFM) redeploys a target virtual service network element (VNF) according to a backup VNFD file, a resource check interface is set in the target VNF, where the resource check information includes a network element identifier of the target VNF, and the VNFM sends the resource check information to the target VNF corresponding to the network element identifier by calling the resource check interface of the target VNF, so as to instruct the target VNF to feed back virtual resource information of the VNFM itself. The resource check may be a preset automatic triggering mechanism with periodicity, or may be initiated by a user after the target VNF deployment is completed.

502. When receiving the target virtual resource information sent by the target virtual service network element, the virtual resource management device compares the target virtual resource information with the virtual resource information of the target virtual service network element recorded in the database, and if the target virtual resource information is different from the virtual resource information of the target virtual service network element recorded in the database, the step 503 is executed; if the target virtual resource information is different from the virtual resource information of the target virtual service network element recorded in the database, executing step 504;

in this embodiment, when receiving target virtual resource information sent by the target VNF, comparing the target virtual resource information with virtual resource information of the target virtual service network element recorded in the database, specifically, in the embodiment shown in fig. 4, comparing VDU information is performed, so as to determine whether a current target virtual resource of the target VNF is consistent with virtual resource information of the target virtual service network element recorded in the database, and when the target virtual resource information is different from the virtual resource information of the target virtual service network element recorded in the database, executing step 503; when the target virtual resource information is different from the virtual resource information of the target virtual service network element recorded in the database, step 504 is executed.

503. The virtual resource management equipment generates prompt information;

in this embodiment, when the target virtual resource information is different from the virtual resource information of the target virtual service network element recorded in the database, the virtual resource management device generates a prompt message for prompting that the virtual resource of the target VNF of the user is inconsistent with the virtual resource information of the target virtual service network element recorded in the database.

504. The virtual resource management device does not generate the hint information.

In this embodiment, when the VNFM does not receive the target virtual resource information fed back by the target VNF, it indicates that the authentication fails, and the VNFM cannot perform resource check on the target VNF through the resource check interface; or, when the link fails and the target VNF cannot transmit the target virtual resource information to the VNFM, the VNF itself has a problem, and does not belong to the virtual resource check category, and it is not necessary to generate the prompt message. And when the target virtual resource information is the same as the backup DF, the virtual resource of the target VNF is consistent with the virtual resource described by the backup DF, so that the resource check is passed without generating a prompt message.

In the embodiment of the application, after the target VNF is redeployed, the virtual resources are theoretically consistent with those before deployment, but in the deployment process, deployment errors or changes of the virtual resources may occur, so that resource checking is required, and when target virtual resource information sent by the target VNF is not received, prompt information does not need to be generated; when receiving target virtual resource information sent by a target VNF, comparing the target virtual resource information with virtual resource information of a target virtual service network element recorded in a database, and when the target virtual resource information is different from the virtual resource information of the target virtual service network element, generating prompt information for prompting a user to repair the virtual resource of the target VNF; when the two are the same, no prompt information needs to be generated. Therefore, after the target VNF is deployed, whether the DF backup of the virtual resource of the target VNF is consistent or not can be checked, and a prompt is sent when the DF backup is inconsistent, so that timely modification is facilitated, and normal operation of network services provided by the target VNF is ensured.

The above embodiment describes a method for managing virtual resources, and a virtual resource management device using the method is described below by a modular device embodiment.

Referring to fig. 6, an embodiment of the present application provides a virtual resource management device, including:
