Description

Technical Field

[0001] The present invention relates to network function virtualization (NFV) technology, and in particular to a deployment method, device, equipment and storage medium of a virtual network function (VNF). Background Art

[0002] Network Function Virtualization (NFV) refers to software processing that carries many functions by using general-purpose hardware and virtualization technology. NFV can decouple software and hardware and abstract functions, so that network device functions no longer rely on dedicated hardware, resources can be fully and flexibly shared, and new services can be developed and deployed quickly. It can also perform automatic deployment, elastic scaling, fault isolation, and self-healing based on actual business needs.

[0003] In the related technologies, the management and orchestration system of NFV mainly includes: network function virtualization orchestrator (NFVO), virtualized network function manager (VNFM), and virtualized infrastructure manager (VIM). Among them, NFVO is responsible for the orchestration management of global resources and the management of network service life cycle; VNFM is responsible for the life cycle management of VNF, such as the parsing and processing of VNFD (Virtual Network Function Descriptor), the initialization of VNF instances, and the expansion and contraction of VNF; VIM is responsible for the scheduling and management of hardware resources and virtualized resources, and provides a virtualized resource pool to the upper layer.

[0004] During VNF instantiation, the operator triggers the instantiation process through NFVO and selects one of the resource pools for this instantiation. NFVO provides the instantiation information and the specified resource pool information to VNFM so that VNFM can complete the VNF instantiation operation. The orchestration, creation and deployment of resources are distributed in the same resource pool, which makes it impossible to complete the deployment of VNF across resource pools. If there are multiple resource pools, VNFs can only be deployed to different resource pools, resulting in repeated deployment of VNFs and the resources of the resource pool cannot be reasonably allocated and used. Summary of the invention

[0005] In view of this, embodiments of the present invention provide a method, apparatus, device and storage medium for deploying a virtual network function, aiming to implement cross-resource pool deployment of a virtual network function.

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] The embodiment of the present invention provides a VNF deployment method, which is applied to NFVO. Figure 1 As shown, the method includes:

[0034] Step 101, based on VNFD information of the instantiated VNF, determining at least two resource pools corresponding to the VDU in the VNFD information;

[0035] Step 102: Send a request for instantiating the VNF to the VNFM based on the at least two resource pools.

[0036] In the embodiment of the present invention, NFVO can determine at least two resource pools based on the VDU in the VNFD information, and can deploy multiple VNFCs under the VDU to the at least two resource pools during the instantiation process of the VNF, thereby realizing the cross-resource pool deployment of the VNF, so that the resources of each resource pool can be reasonably utilized, and it is beneficial to reduce the repeated deployment of the VNF.

[0037] In actual applications, there may be multiple VDUs in the VNFD information, and there are VDUs corresponding to at least two resource pools among the multiple VDUs, that is, some or all of the multiple VDUs correspond to multiple resource pools, so that VNFC cross-resource pool deployment can be performed on the VDUs with multiple resource pools.

[0038] In some embodiments, before determining at least two resource pools corresponding to the VDU in the VNFD information, the method further includes:

[0039] Register the VNFD information used to instantiate the VNF, the VDU in the VNFD information carrying resource pool identifiers of the at least two resource pools or trigger information for indicating external input of resource pool identifiers of the at least two resource pools.

[0040] It can be understood that in the embodiment of the present invention, in the process of designing and registering VNFD information, the user introduces resource pool identifiers of multiple resource pools or trigger information for indicating resource pool identifiers of multiple resource pools input externally in the VDU. Here, the resource pool identifier (vimid) can be the name, category, identity identifier and other information of the resource pool. In practical applications, the VNFD information can be registered by registering the VNF package on the NFVO, that is, the VNF package carries the VNFD information.

[0041] For example, when DEMO_VDU1 is instantiated, five VNFCs need to be deployed. Two resource pools are specified in vimid, which can be used for selection during instantiation. The specific examples are as follows:

[0042]

[0043]

[0044] For example, when DEMO_VDU2 is instantiated, three VNFCs need to be deployed. The vimid specifies that the resource pool identifier is obtained from the input parameter. The specific example is as follows:

[0045] DEMO_VDU2:

[0046] …

[0047] properties:

[0048] vimid:{get_input:vimid}

[0049] initial_number_of_instances:3

[0050] …

[0051] In this way, after NFVO obtains the VNFD information of the instantiated VNF, it can obtain multiple resource pools corresponding to each VDU for instantiation based on the description information of each VDU.

[0052] In some embodiments, the NFVO determines, based on VNFD information of the instantiated VNF, at least two resource pools corresponding to the VDU in the VNFD information, including:

[0053] parsing the VDU in the VNFD information, and determining the at least two resource pools based on the resource pool identifier carried by the VDU; or,

[0054] Parse the VDU in the VNFD information, receive an externally input resource pool identifier based on trigger information carried by the VDU, and determine the at least two resource pools.

[0055] For example, for the aforementioned DEMO_VDU1, NFVO can determine that the resource pools that can be instantiated are vim01 and vim02; for the aforementioned DEMO_VDU2, NFVO can determine the resource pool that can be instantiated according to the vimid input by the user in the input interface.

[0056] In some embodiments, based on the at least two resource pools, sending a request to instantiate the VNF to the VNFM includes:

[0057] Sending a request for instantiating the VNF to the VNFM, wherein the request carries resource pool identifiers of the at least two resource pools; or,

[0058] Based on the occupancy status of each of the at least two resource pools, a correspondence between the multiple VNFCs to be deployed in the VDU and the at least two resource pools is allocated, and a request for instantiating the VNF is sent to the VNFM, where the request carries the correspondence.

[0059] It can be understood that NFVO does not need to allocate the number of VNFCs required to be deployed in each of the multiple resource pools of VDU, and can send the resource pool identifiers of the multiple resource pools corresponding to the instantiation of VDU to VNFM along with the request for instantiating VNF, and VNFM determines the deployment number of VNFCs corresponding to each resource pool; or NFVO can allocate the correspondence between the multiple VNFCs to be deployed in the VDU and the at least two resource pools, and carry the correspondence in the request for instantiating VNF, so that VNFM can determine the deployment number of VNFCs corresponding to each resource pool according to the correspondence.

[0060] It is understandable that the number of VDUs in the VNFD information may be one, two, or more, and the NFVO may parse each VDU in the VNFD information to determine the resource pool for instantiation of each VDU. For each VDU, the NFVO allocates the number of VNFCs to be deployed on each resource pool according to the occupancy status of the resource pool, which is the utilization rate of resources in the resource pool, such as CPU utilization rate, storage resource utilization rate, etc. For example, for the aforementioned DEMO_VDU1, NFVO can determine that the resource pools that can be instantiated are vim01 and vim02. Since the resource consumption ratio of vim01 is higher than that of vim02, for the 5 VNFCs to be deployed in DEMO_VDU1, 2 VNFCs are deployed on vim01 and 3 VNFCs are deployed on vim02; for the aforementioned DEMO_VDU2, NFVO can determine that the resource pools that can be instantiated are vim01 and vim03. Since the resource consumption ratio of vim01 is higher than that of vim03, for the 3 VNFCs to be deployed in DEMO_VDU2, NFVO can determine that the resource pools that can be instantiated are vim01 and vim03. Since the resource consumption ratio of vim01 is higher than that of vim03, for the 3 VNFCs to be deployed in DEMO_VDU2, 1 VNFC is deployed on vim01 and 2 VNFCs are deployed on vim03. In this way, the 5 VNFCs under DEMO_VDU1 with the same function are deployed in the two resource pools of vim01 and vim02 respectively; the 3 VNFCs under DEMO_VDU2 with the same function are deployed in the two resource pools of vim01 and vim03 respectively. If vim01 fails, the VNFC deployed on it will fail. At this time, the VNFC with the same function deployed on vim02 and vim03 can continue to provide services, ensuring service reliability.

[0061] The embodiment of the present invention also provides a VNF deployment method, which is applied to VNFM. Figure 2 As shown, the method includes:

[0062] Step 201, receiving a request for instantiating a VNF sent by the NFVO;

[0063] Step 202: deploy multiple VNFCs in the VDU into at least two resource pools based on the request.

[0064] Here, based on the request, the VNFM may determine at least two resource pools that the VDU may implement, and deploy multiple VNFCs to be deployed in the VDU into the at least two resource pools.

[0065] In some embodiments, the request carries a correspondence between the multiple VNFCs to be deployed in the VDU and the at least two resource pools, and the deploying the multiple VNFCs in the VDU to the at least two resource pools based on the request includes:

[0066] Based on the corresponding relationship, the deployment quantity of the VNFCs corresponding to each of the resource pools is determined.

[0067] The corresponding relationship is allocated by the NFVO based on the occupancy status of each resource pool in the at least two resource pools. For details, please refer to the relevant description on the NFVO side mentioned above, which will not be repeated here.

[0068] In some embodiments, the request carries resource pool identifiers of the at least two resource pools, and the deploying the multiple VNFCs in the VDU to the at least two resource pools based on the request includes:

[0069] Based on the at least two resource pools, the number of deployed VNFCs corresponding to each resource pool is randomly allocated, or the number of deployed VNFCs corresponding to each resource pool is allocated according to a pre-set strategy.

[0070] Here, if the request for instantiating the VNF does not specify the number of VNFCs to be deployed corresponding to each resource pool in the VDU, the VNFM can randomly allocate the number of VNFCs to be deployed corresponding to each resource pool, or allocate them according to predefined rules. The predefined rules can come from VNFD information or from VNFM. For example, the number of VNFCs to be deployed on each resource pool is allocated according to the occupancy status of each resource pool.

[0071] In this way, VNFM can deploy multiple VNFCs of VDU into at least two resource pools, thereby realizing cross-resource pool deployment of VNF, making the resources of each resource pool reasonably utilized and helping to reduce repeated deployment of VNF.

[0072] The present invention is further described in detail below in conjunction with application examples.

[0073] Figure 3 In the application embodiment shown, the VNF deployment system includes: NFVO, VNFM and multiple VIMs (such as VIM1, VIM2, and VIMn shown in the figure). Figure 3 As shown in the figure, the deployment methods of VNF include:

[0074] Step 301, instantiate VNF;

[0075] Here, NFVO receives the instantiation VNF information input by the operator, for example, the vnf package of the selected VNF to be instantiated. It is understandable that the vnf package needs to be registered on NFVO in advance, and after registering the vnf package, NFVO creates VNFR (virtualized network function record) information.

[0076] Step 302, query VNFR information;

[0077] NFVO queries VNFR information based on the instantiated VNF information.

[0078] Step 303, query VNFD information;

[0079] The NFVO determines that the VNFR information has been queried, and sends a request to the VNFM to query the VNFD information.

[0080] Step 304, returning VNFD information;

[0081] VNFM returns VNFD information to NFVO.

[0082] Step 305, determining the vimid information in the VNFD information;

[0083] After NFVO obtains the VNFD information, it can determine the information of the resource pool of the VDU in the VNFD information in two ways, as follows:

[0084] Method 1: parse VDU and get the vimid of the resource pool;

[0085] Method 2: parse VDU and receive the vimid of the resource pool input by inputs (input interface).

[0086] Step 306, allocating the number of VNFCs deployed on each resource pool according to the vimid information;

[0087] The NFVO allocates the VNFCs to be deployed to different resource pools according to the resource pool information obtained in step 305 and in combination with the actual usage of the resource pools.

[0088] Step 307, sending a request to instantiate the VNF to the VNFM;

[0089] NFVO triggers the process of instantiating VNF and sends the inputs information and the deployment relationship between the VNFC to be deployed and the resource pool to VNFM.

[0090] Step 308, parsing inputs and VNFD information;

[0091] The VNFM parses the inputs information and the VNFD information to obtain the deployment relationship between the VNFC and the resource pool. If the deployment relationship between the VNFC and the resource pool is not specified in step 306, the VNFM allocates it randomly or according to a predefined rule.

[0092] Step 309, apply for authorization;

[0093] VNFM sends an authorization request to NFVO, which carries the relationship between VNFC and multiple deployment resource pools and requests NFVO authorization.

[0094] Step 310, returning authorization information;

[0095] NFVO returns the authorization information to VNFM.

[0096] Step 311, creating resources in indirect mode;

[0097] VNFM sends an indirect mode create resource request to NFVO.

[0098] Step 312, creating resources in VIM1;

[0099] NFVO creates resources in VIM1 based on the indirect mode creation resource request.

[0100] Step 313, creating resources in VIM2;

[0101] NFVO creates resources in VIM2 based on the indirect mode creation resource request.

[0102] Step 314, create resources in VIMn.

[0103] NFVO creates resources in VIMn based on the indirect mode create resource request.

[0104] In order to implement the method of the embodiment of the present invention, the embodiment of the present invention also provides a VNF deployment device, which corresponds to the VNF deployment method on the NFVO side mentioned above, and each step in the above-mentioned VNF deployment method embodiment is also fully applicable to the VNF deployment device embodiment.

[0105] like Figure 4 As shown, the VNF deployment device 400 includes: a determination module 401 and a request module 402, wherein the determination module 401 is used to determine at least two resource pools corresponding to the VDU in the VNFD information of the instantiated VNF based on the VNFD information of the instantiated VNF; the request module 402 is used to send a request for instantiating the VNF to the VNFM based on the at least two resource pools.

[0106] In some embodiments, the determination module 401 is specifically used to:

[0107] parsing the VDU in the VNFD information, and determining the at least two resource pools based on the resource pool identifier carried by the VDU; or,

[0108] Parse the VDU in the VNFD information, receive an externally input resource pool identifier based on trigger information carried by the VDU, and determine the at least two resource pools.

[0109] In some embodiments, the request module 402 is specifically configured to:

[0110] Sending a request for instantiating the VNF to the VNFM, wherein the request carries resource pool identifiers of the at least two resource pools; or,

[0111] Based on the occupancy status of each of the at least two resource pools, a correspondence between the multiple VNFC virtual network function components to be deployed in the VDU and the at least two resource pools is allocated, and a request for instantiating the VNF is sent to the VNFM, where the request carries the correspondence.

[0112] In some embodiments, the VNF deployment device 400 also includes: a registration module 403, used to register the VNFD information, the VDU in the VNFD information carries the resource pool identifiers of the at least two resource pools or trigger information indicating external input of the resource pool identifiers of the at least two resource pools.

[0113] In actual application, the determination module 401, the request module 402 and the registration module 403 can be implemented by a processor in the VNF deployment device 400. Of course, the processor needs to run the computer program in the memory to implement its function.

[0116] In some embodiments, the request carries a correspondence between a plurality of VNFCs to be deployed in the VDU and the at least two resource pools, and the deployment module 502 is specifically configured to:

[0117] Based on the corresponding relationship, the deployment quantity of the VNFCs corresponding to each of the resource pools is determined.

[0118] In some embodiments, the request carries resource pool identifiers of the at least two resource pools, and the deployment module 502 is specifically configured to:

[0119] Based on the at least two resource pools, the number of deployed VNFCs corresponding to each resource pool is randomly allocated, or the number of deployed VNFCs corresponding to each resource pool is allocated according to a pre-set strategy.

[0120] In actual application, the receiving module 501 and the deployment module 502 can be implemented by a processor in the VNF deployment device 500. Of course, the processor needs to run the computer program in the memory to implement its function.

[0121] It should be noted that: the VNF deployment device provided in the above embodiment only uses the division of the above program modules as an example when deploying VNF. In actual applications, the above processing can be assigned to different program modules as needed, that is, the internal structure of the device is divided into different program modules to complete all or part of the processing described above. In addition, the VNF deployment device provided in the above embodiment and the VNF deployment method embodiment belong to the same concept.
