Problems solved by technology

In fact, when the VIM needs to restart the virtual machine, a VM change process will cause all the related virtual machines to restart, causing the business units running on these virtual machines to fail to work, causing business interruption
[0005] Aiming at the problem in the related technology that the change of the virtual machine of the VNF leads to the interruption of the business units running on these virtual machines, no effective solution has been proposed so far

Embodiment approach 1

[0088] In this preferred implementation manner, VNFM implements the VNF custom VM change policy.

[0089] Figure 4 is the flow of a preferred method for changing virtual machine resources according to an embodiment of the present invention Figure 1 ,like Figure 4 As shown, the process of virtual machine resource change includes the following steps (step S402 to step S408):

[0090] When the user executes the VNF change process (such as expansion, shrinkage, upgrade, etc.) through NFVO, NFVO initiates a VNF change request to VNFM, and the request carries change parameters, such as the changed virtual network element, operation type and other parameters related to the operation Wait. VNFM changes virtual machine resources. The VNFM performs necessary preparatory work, such as verifying whether the virtual network element in the request is legal or not.

[0091] Step S402, the VNFM determines the VM that needs to be changed according to the VM change policy of the VNF. Fo...

Embodiment approach 2

[0098] In this preferred implementation manner, VNFM implements the VNF custom VM change policy.

[0099] Figure 5 is the flow of a preferred method for changing virtual machine resources according to an embodiment of the present invention Figure II ,like Figure 5 As shown, the process of changing virtual machine resources includes the following steps (step S502 to step S508):

[0100] When the VNFM actively initiates a VM change, for example, the VNFM determines the list of virtual machines that need to be changed according to the load of the VNF, and according to the VM change policy of the VNF, for example, the VNFM according to the pre-configured rules or the attributes of the VNF virtual machines recorded locally. Backup mechanism, load sharing mechanism, etc., to determine the batch of VMs that need to be changed.

[0101] In step S502, the VNFM requests the NFVO to change the VM, and the request carries the changed VM information, such as the list of VMs to be cha...

Embodiment approach 3

[0107] In this preferred implementation manner, the VNFM negotiates with the VNF to realize the VM change policy.

[0108] Image 6 is the flow of a preferred method for changing virtual machine resources according to an embodiment of the present invention Figure three ,like Image 6 As shown, the process of virtual machine resource change includes the following steps (step S602 to step S614):

[0109] When the user executes the VNF change process (such as expansion, shrinkage, upgrade, etc.) through NFVO, NFVO initiates a VNF change request to VNFM, and the request carries the information of the changed VNF, such as the changed virtual network element, operation type and other related operations parameters etc. The VNFM performs necessary preparatory work, such as verifying whether the virtual network element in the request is legal or not.

[0110] In step S602, the VNFM initiates a VM change request to the VNF (if the VNFM determines the virtual machine information to ...

Abstract

Disclosed are a virtual machine resource changing method, device and virtual network function device, the virtual machine resource changing method comprising: determining a virtual machine changing strategy of a VNF; changing virtual machines in batches according to the changing strategy. The present invention solves the problem of interruption of service units running on the virtual machines resulting from virtual machines changing of the VNF, thus allowing the service units running on some or all of the virtual machines to be uninterrupted.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for changing virtual machine resources, and a virtual network function (Virtualized Network Function, VNF for short) device. Background technique [0002] In order to improve equipment resource utilization, service deployment efficiency, and reduce operation and maintenance costs, the European Telecommunications Standards Institute (ETSI) has formulated a network function virtualization (Network Functions Virtualization, NFV) protocol standard. The end-to-end reference architecture introduces Network Functions Virtualization Orchestrator (NFVO for short), Virtualized Network Function Manager (VNFM for short), and Virtualized Infrastructure Manager (Virtualized Infrastructure Manager for short). VIM), Network Functions Virtualization Infrastructure (NFVI for short), VNF and other functional units. [0003] NFVO is mainly responsible for network services, vir...
