Description

Method, device, equipment and storage medium for determining network element deployment information

Technical Field

The present invention relates to the technical field of IT applications, and in particular, to a method, an apparatus, a device, and a storage medium for determining network element deployment information.

Background

Management of NFV (Network Function Virtualization) is implemented by MANO (NFV Management and organization) systems. The MANO system is a brand-new cloud management system, and mainly comprises the functions of life cycle management of network elements required by cloud management, management of loading templates and installation packages required by the network elements, management and distribution of network resources and the like. The life cycle management function of the network element is related to the basic function of network/network element management, and is a new function of a network management system.

MANOs are composed of NFVO + (Network Function Virtualization orchestrator), VNFM (virtualized Network Function Manager), and VIM (virtualized Infrastructure Manager). The VNFM implements lifecycle management of a virtualized Network element VNF (virtualized Network Function module), including management and processing of a VNFD (virtualized Network Function Descriptor), initialization of a VNF instance, and capacity expansion/reduction of the VNF. The VIM is a virtualized infrastructure management system, and is mainly responsible for management of infrastructure layer hardware resources, virtualized resources, and the like.

From the prior implementation, during deployment of VNF instantiation, a virtual machine belongs to a single creation. In the process of creating the virtual machine, the scheduling mechanism in the virtual layer VIM uses the native Scheduler scheduling policy of the nova component in the OpenStack, which can only refer to the deployed virtual machine resources to decide the location of the next virtual machine deployment. However, when a large number of virtual machines are deployed, the performance of the virtual machines cannot be guaranteed by the existing scheme.

Detailed Description

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

Referring to fig. 1, fig. 1 is a flowchart of a method for determining network element deployment information according to an embodiment of the present invention, which is applied to NFVO, and as shown in fig. 1, includes the following steps:

step 101, obtaining a VNFR of at least one VNF.

In an embodiment of the present invention, the VNFR may be selected from the created VNFRs according to an input of an operator. For the VNFR that has already been created, a status identification is set, including instance ID information of the VNF, and the like. Therefore, the corresponding VNFR can be selected according to its status identifier, so that the resource pre-assembly instantiation operation, i.e. network element optimal deployment instantiation, is performed on it.

Accordingly, in an embodiment of the present invention, before this step, the method may further include: creating the VNFR. Specifically, information of a VNF network element package requiring resource pre-assembly, such as VNFD and VNFM, may be acquired according to input of an operator. And then, requesting the VNFM to create the VNFR according to the information of the VNF network element package. Specifically, the NFVO may send a VNF instance record request to the VNFM, where the request may include information such as the identifications of the NFVO and the VNFM, the VNF package ID, and the VNF instance name. After that, the VNFM returns the creation result of the VNFR, which may include the VNF Instance ID (VNF Instance identification) in the result, to the NFVO.

And 102, acquiring the input parameters of the VNF according to the VNFR.

In the embodiment of the present invention, the input parameters refer to parameters (inputs) that the VNFM needs NFVO to provide for determining each VNF.

Specifically, in this step, the NFVO may obtain, according to the VNFR, information of the input parameter corresponding to the VNFR from the VNFM. Specifically, NFVO may invoke C6 in the real instantiation process: the query VNFD Req interface includes a VNF Package ID (VNFD packet identifier) to query VNFM information.

And then, acquiring the input parameters according to the information of the input parameters. For example, an operation page may be provided to the operator, and the operator may input corresponding information on the operation page, so that the input parameters may be acquired. Specifically, C6 in the VNFM call instantiation flow: and returning parameters by the QueryVNFD Response interface, wherein the returned parameters comprise the analyzed VNFD information and input parameters needing NFVO input.

And 103, acquiring pre-assembly resource information required by pre-assembly of the VNF from the VNFM according to the input parameters.

Specifically, in this step, the NFVO may send a VNF resource query request to the VNFM, where the VNF resource query request includes the input parameter. And then, receiving the pre-assembly resource information sent by the VNFM according to the VNF resource inquiry request.

Specifically, NFVO calls new C6: the Query VNF Resource interface may include VNF network element pre-assembly list information, which may include VNFD identification, VNF instance ID, instantiation input parameter list information (e.g., inputs), and so on. And the VNFM analyzes the VNFD and inputs according to the parameters carried in the request, and calculates and analyzes the pre-assembly resource information required by the single VNF network element.

The pre-assembled resource information may include, for example, information such as a Virtual Machine specification, a Virtual Machine (VM) number, an affinity, a counter affinity, an Available Zone, a QoS (Quality of Service), whether to enable a Non Uniform Memory Access (NUMA) affinity, and the like.

And 104, acquiring the current virtual layer resource use information from the VIM.

Specifically, in this step, the NFVO may send a resource information query request to the VIM. And then, receiving the current virtual layer resource use information sent by the VIM according to the resource information query request.

Specifically, NFVO calls a newly added C7 interface, a List resource map Req interface, to query the VIM about the current resource information usage of the virtual layer.

The current virtual layer resource usage information may include, for example, virtual layer resource static basic information including AZ, HA, HOST basic information and relationship, TOR and physical server relationship, physical server and HOST relationship, and the like, and virtual layer dynamic capacity information may include querying NUMA TOPO and HOST resource capacity usage, and the like.

And 105, determining the deployment information of the VNF network element according to the pre-assembly resource information and the current virtual layer resource use information.

Specifically, in this step, the NFVO may obtain the virtual layer resource static basic information and the virtual layer dynamic capacity information included in the current virtual layer resource usage information, and then determine information of a host to be deployed by the virtual machine VM in the VNF according to the virtual layer resource static basic information, the virtual layer dynamic capacity information, and the pre-assembly resource information.

Then, the NFVO may perform an instantiation operation of the VNF according to the deployment information of the VNF. Specifically, the NFVO sends an instantiation request to the VNMF, and receives a resource authorization request sent by the VNFM according to the instantiation request. Then, the NFVO sends a resource authorization response to the VNFM, where the resource authorization response includes the deployment information of the VNF.

On the basis of the above embodiment, to improve the accuracy of creating a virtual machine, the NFVO may send a resource reservation request to the VIM, where the resource reservation request is used to request the VIM to perform resource reservation.

Specifically, NFVO may call the newly added C7 interface: the Reserve Resources interface makes resource reservations. The interface parameters for resource reservation to the VIM virtual layer may include a reserved host name, a numa list for applying for reservation, a number of CPU cores for applying for reservation, a size of a memory for applying for reservation, a bandwidth list for applying for reservation, and the like. The VIM virtual layer will return a reserve _ ID reservation ID to NFVO +.

Since the reserved resources are time-efficient, the NFVO may send a resource status query request to the VIM, where the resource status query request is used to query the status of the reserved resources, and specifically, the NFVO may asynchronously query the reserved status of the virtual layer resources through the newly added List ReserveDetails. Wherein the status may include resources being reserved, resources being reserved successfully, resources being reserved failed, resources being released failed, and the like.

Referring to fig. 2, fig. 2 is a flowchart of a method for determining network element deployment information according to an embodiment of the present invention, which is applied to a VNFM, and as shown in fig. 2, the method includes the following steps:

step 201, obtaining at least one input parameter of VNF from NFVO.

Wherein the meaning of the input parameters can refer to the description of the previous embodiments.

Optionally, before this step, the method may further include: and creating the VNFR of the VNF according to the request of the NFVO. After the VNFR is created, the creation result of the VNFR may also be returned to the VNFO.

Step 202, sending pre-assembly resource information required by pre-assembly of the VNF to the NFVO according to the input parameters.

Specifically, in this step, the VNFM may receive a VNF resource query request sent by the VNFO, where the VNF resource query request includes the input parameter. Then, pre-assembly resource information required for pre-assembling the VNF is determined according to the input parameters. Finally, the pre-assembled resource information is sent to the VNFO. The pre-assembly resource information may include, for example, information such as virtual machine specification, number of virtual machines, affinity \ inverse affinity, Available Zone, QoS, whether NUMA affinity is enabled, and the like.

On the basis of the above embodiment, the VNFM may further receive an instantiation request sent by the VNFO, and send a resource authorization request to the NFVO according to the instantiation request. Then, a resource authorization response sent by the VNFO is received, the resource authorization response includes the deployment information of the VNF, and the virtual resource of the VNF is created according to the deployment information of the VNF.

Referring to fig. 3, fig. 3 is a flowchart of a method for determining network element deployment information according to an embodiment of the present invention, which is applied to a VIM, and as shown in fig. 3, the method includes the following steps:

step 301, sending current virtual layer resource usage information to the VNFO, so that the VNFO determines deployment information of the VNF according to the pre-assembled resource information and the current virtual layer resource usage information.

Specifically, in this step, the VIM may receive a resource information query request sent by the VNFO, and then send current virtual layer resource usage information to the VNFO according to the resource information query request.

Further, on the basis of the above embodiment, the method further includes:

and receiving a resource reservation request sent by the VNFO, and reserving the virtual resources of the VNF according to the resource reservation request. By the method, timeliness of reserved resources can be guaranteed, and success of virtual machine deployment is guaranteed.

Further, on the basis of the above embodiment, the method further includes:

and receiving a resource state query request sent by the VNFO, and sending state information of a virtual layer to the VNFO according to the resource state query request.

The status information may include resources being reserved, resources being reserved successfully, resources being reserved failed, resources being released failed, and the like.

As mentioned above, from the current existing implementation, during the VNF normal instantiation deployment process, the virtual machine belongs to a single creation. In the process of creating the virtual machine, a native Scheduler scheduling policy of a nova component in an OpenStack is used by a scheduling mechanism in the virtual layer VIM, and the scheduling mechanism can only refer to the deployed virtual machine resources to decide the deployment position of the next virtual machine, so that optimal deployment can be ensured by a single step. However, when a large number of virtual machines are deployed, the above method cannot achieve optimal deployment of VNFs from a global perspective. Especially for a planned deployment scenario, how many VNF network elements need to be deployed in a future period of time can be predicted, and at this time, VNFs of different manufacturers need to be pre-assembled in advance in an instantiation process on NFVO +, so that the utilization rate of a resource pool is ensured. Therefore, the virtual machine can be optimally deployed by directly referring to the pre-assembly result in the VNF network element instantiation. The scheme is a network service planned batch instantiation scene aiming at a telecom cloud scene. Based on the above consideration, the embodiment of the present invention provides a solution that considers introducing VNF resource pre-assembly in the VNF instantiation process, so as to implement optimized deployment in the multiple network element instantiation process.

Specifically, NFVO + selects multiple VNFRs (virtualized Network Function Record). In the instantiation process, the NFVO + acquires all VNF network element resource demand lists (the number, specifications, affinity, and the like) that need to be deployed by the current time node from each manufacturer VNFM, and the NFVO + calculates the optimal deployment position of each VNF network element through internal processing of the NFVO + after acquiring the usable condition of the virtual layer resource at the current time. And then, the NFVO + continues to perform instantiation operations of the multiple VNFs through an instantiation interface in the NFVO + -VNFM interface, wherein the instantiation operations include that the VNFM requests resource authorization to the NFVO +, and the NFVO + informs the VNFM of the optimal deployment positions of the virtual machines required to be deployed by the multiple VNF network elements, so that batch network element optimal deployment is completed.

By means of resource pre-assembly in the VNF network element instantiation process, the utilization rate of a single host and the whole resource pool in the network element instantiation deployment stage can be effectively improved, and resource fragments of the single host and the whole resource pool are minimized.

The following describes specific implementation procedures of the embodiments of the present invention in detail with reference to specific embodiments. In the embodiment of the present invention, the VNF instantiation creation process is divided into two independent processes: the first procedure is that the operator selects a plurality of VNF packages for VNFR creation. The VNFR is an instance record of the VNF, which contains the instance ID of the VNF network element. The second process is that the operator selects multiple VNFRs for VNF instantiation. In the instantiation process, the NFVO + initiates a multi-network-element resource pre-assembly request, and the multi-network-element resource pre-assembly work is completed through the whole resource pre-assembly process. The key point of the whole resource pre-assembly process is workflow interaction among NFVO +, VNFM and VIM, the NFVO + acquires resource information required by deployment of each network element analyzed by each VNFM, and simultaneously acquires the residual condition of virtual layer resources at the current moment, and the optimized deployment result of the VNF network element including the virtual machine is realized through internal calculation of the NFVO +. In the subsequent instantiation process, in the process that the VNFM requests the NFVO + for authorization, the NFVO + informs the VNFM of the authorization result, and then VNF network element instantiation is continued according to the optimized deployment result. In the instantiation process, resource pre-assembly is carried out through the NFVO +, and the VNFM already knows the physical host location where the virtual machine of each VNF network element should be deployed, so that the network element instantiation action can be directly carried out at the determined deployment location.

Referring to fig. 4, fig. 4 is a schematic diagram of a process of creating a VNFR in the embodiment of the present invention, including:

step 401, an operator selects a plurality of network elements and inputs corresponding parameters.

Step 402, NFVO + initiates creation of VNF instance.

Specifically, a VNF network element package (which needs to include VNFD and VNFM) that needs resource pre-assembly is selected in NFVO +. NFVO + initiates a request to create a VNF instance record to the VNFM according to the operator's input parameters.

The request may include information such as the identities of NFVO + and VNFM, the VNF package ID, and the VNF instance name.

Step 403, the VNFM returns the creation result of VNFR to NFVO +.

The VNF Instance ID may be included in the result.

Step 404, NFVO + feeds back to the operator that creating VNFR is complete.

Referring to fig. 5, fig. 5 is a schematic flowchart of a VNF network element optimized deployment instantiation in the embodiment of the present invention. Three main functional blocks are mainly involved in this flow: NFVO +, VNFM, and VIM. The NFVO + initiates a VNF creation request message to the VNFM according to the requirement and verifies and authorizes the virtual resource required by the VNF creation; the VNFM can manage the lifecycle of the VNF; the VIM can create the required VMs for the VNF. In conjunction with fig. 5, the process includes:

step 501, an operator initiates an optimal deployment instantiation operation for a plurality of VNF network elements on an NFVO + interface.

Step 502, NFVO + selects multiple VNF instance records to operate on.

Specifically, NFVO + selects the VNFR that has been created in the flow shown in fig. 4, where the VNFR has a status identifier, and includes instance ID information of the VNF. And carrying out resource pre-assembly instantiation operation on the network element, namely realizing optimal deployment instantiation of the network element.

Step 503, NFVO +, initiates a request to query VNFD to the corresponding one or more VNFMs.

NFVO + calls C6 already present in the real instantiation flow: the query VNFD Req interface includes a VNF Package ID, and queries VNFD information from the VNFM.

Because the VNF package in the NFVO + relates to cross-vendor, the VNF package of each vendor is analyzed by the VNFM of each vendor, and the NFVO + circularly queries the VNFD related to each VNFR from each VNFM to obtain inputs (input) parameters.

And step 504, inquiring and analyzing the locally stored VNFD information corresponding to the VNF packet by each manufacturer VNFM.

Step 505, VNFM returns a response of VNFD input parameters.

Specifically, the VNFM call instantiates C6 already existing in the flow: and returning input parameters by a query VNFD Response interface, wherein the parameters comprise the analyzed VNFD information and input parameters needing NFVO + input.

In step 506, the operator inputs corresponding inputs parameters and sends them to NFVO +.

Specifically, according to the inputs parameters to be input parsed by the VNFM, the operator uniformly inputs the inputs on the NFVO + interface.

Because NFVO + circularly queries VNF inputs parameters to each VNFM uniformly, an operator can uniformly input all the inputs parameters on a page, and good interaction with users is realized.

And 507, initiating a resource pre-assembly process in the instantiation process to the VNFM by the NFVO +.

Specifically, NFVO + calls new C6: query VNF Resource interface, which may include VNF network element pre-assembly list information (which may include VNFD identification, VNF instance ID, instantiation input parameter list information, etc.), and the like.

And step 508, the VNFM analyzes the VNFD and inputs according to the parameters carried in the request, and calculates and analyzes the resources required by the pre-assembly of the single VNF network element.

Specifically, the VNFM analyzes VNFDs and inputs in the VNF package, and analyzes virtual resources required by VNF instantiation, which mainly include information such as virtual machine specification, number of Virtual Machines (VMs), affinity \ inverse affinity, Available Zone, QoS (Quality of Service), whether Non Uniform Memory Access (NUMA) affinity is enabled, and the like.

In step 509, the VNFM returns the list of parameters required for pre-assembly of each VNF to the NFVO +.

Specifically, the response return parameter information may include information such as the specification of the virtual machine, the number of virtual machines, affinity \ inverse affinity, Available Zone, QoS, whether NUMA affinity is enabled, and the like.

Step 510, NFVO + queries VIM for virtual layer resource capacity information.

Specifically, NFVO + calls a newly added C7 interface, a List resource map Req interface, to query the VIM for the virtual layer resource capacity information, that is, the current usage information of the virtual layer resource.

In particular, the parameters in the interface request may contain hostname information.

The VIM returns a query response, and the response interface parameters can comprise a region, an AZ, an HA group, a Numa topological structure, a Numa list, a Numa ID, a CPU distribution ratio, a memory distribution ratio and the like, a host bandwidth and the like to which the host belongs.

And step 511, performing optimized deployment calculation by NFVO +.

Specifically, the NFVO + performs internal processing, and for N virtual machines included in a plurality of VNFs to be deployed, pre-assembly of the virtual machines is performed according to a current virtual layer resource usage situation, so as to obtain an optimized deployment location of each VNF network element.

Specifically, NFVO + queries The virtual layer resource static basic information (including AZ, HA (high reliability), HOST basic information and relationship, TOR (The online Router, Onion Router) and physical server relationship, physical server and HOST relationship, etc.), and dynamically refreshes The query VIM virtual layer dynamic capacity information (including query NUMA TOPO and HOST resource capacity usage, etc.). Then, the NFVO + obtains id information of a host to be deployed by the VM included in the VNF network element according to each VNF pre-assembly parameter acquired by querying the VNF Resource interface, and by combining the queried global Resource capacity information of the VIM virtual layer, so that the VM is conveniently and directly deployed on the physical host when being instantiated.

And step 512, NFVO + reserves the virtual layer resources.

Aiming at the pre-assembly result obtained by the calculation of NFVO +, NFVO + calls a newly added C7 interface: the Reserve Resources interface makes resource reservations.

Specifically, the interface parameters for NFVO + to request resource reservation from the VIM virtual layer may include a reserved host name, a numa list for applying for reservation, a number of CPU cores for applying for reservation, a memory size for applying for reservation, and a bandwidth list for applying for reservation. The VIM virtual layer will return a reserve _ ID reservation ID to NFVO +.

Because the reserved resources have certain timeliness, the NFVO + can asynchronously query the reservation state of the virtual layer resources through the newly added List ReserveDetails. Meanwhile, NFVO + supports the cancellation of resource pre-assembly functionality. Accordingly, the virtual layer state of an asynchronous query may include: resources are being reserved, resources are successfully reserved, resources are unsuccessfully reserved, resources are being released, and resources are unsuccessfully released.

Step 513, NFVO + optimized deployment instantiation interface.

NFVO + calls a VNF instantiation interface, performs batch instantiation operation of VNF network elements, and prepares to call VIM virtual layer resources to pull up a virtual machine.

Specifically, before the NFVO + calls the instantiation interface, the NFVO + interface may display the resource pre-assembly result for each VNF network element, and the resource fragmentation rate of each physical host. The user can choose to continue the instantiation or cancel the resource pre-assembly and cancel the instantiation process operation.

Step 514, the VNFM sends a resource authorization request to the NFVO +.

After the instantiation request is sent to each manufacturer VNFM, the VNFM returns Job ID to NFVO +, and meanwhile, a grantLifecycle Req (authorization cycle request) interface is called to authorize resources to the NFVO +.

Step 515, NFVO + query the resource pre-assembly location.

And the NFVO + queries the position information of the VM to be deployed of each VNF, which is calculated through the internal processing of the NFVO +. The NFVO + numbers the VMs according to the VM information which is returned by all the VNFMs and is to be deployed by each VNF, and the corresponding relation between each VM and the pre-assembled host computer is recorded by an internal database. By querying the correspondence, the pre-assembled host of each VM may be obtained.

Step 516, NFVO + returns a resource authorization response to the VNFM.

Specifically, the resource authorization response parameter returned by the NFVO + to the VNFM should include a VIM ID and a VM deployment location list object, where the object includes VM number information, VM deployment host name information, and VM deployment NUMA ID information.

And 517, acquiring the specific deployment position of the VM by the VNFM, and calling a VIM northbound API (application programming interface) to create the VNF-related virtual resources through the NFVO + indirect mode.

And 518, the NFVO + completes the optimized deployment of the VNF network element, returns the successful instantiation to the user, and can check the resource use condition and the resource fragmentation rate of the virtual layer.

As can be seen from the above description, in the embodiment of the present invention, the resource pre-assembly process and function of the NFVO in the VNF network element instantiation process are realized, and the existing instantiation process can be completed, so as to achieve the function and effect of optimal deployment of multiple VNF instances. The resource pre-assembly completed by NFVO + in the instantiation process is performed, and meanwhile, the VIM virtual layer is required to lock the resource, so that the occupation condition of the deployed resource caused by abnormal conditions is considered. In addition, innovative requirements are put on the NFVO function in the whole pre-assembly process, and the computation of the optimized deployment of the multi-VNF network element can be realized through internal processing.
