[0053] NFV management is based on the MANO system, which is a cloud management system proposed by the European Telecommunications Standards Institute (ETSI). The system mainly manages the life cycle of network elements required for cloud management, the loading templates required for network elements, the installation packages required for network elements, and network resources. Among them, NFVO+ is used to manage the life cycle of NS, including the instantiation, termination, expansion, and reduction of NS; VNFM is used to manage the life cycle of VNF network elements, including the management of VNF descriptions (VNFD, VNFDDescriptor), the instantiation of VNF network elements, and the expansion and reduction of VNF network elements; VIM is used to manage the hardware resources and virtualization resources of the infrastructure layer, including the execution of life cycle management operations such as power on and off, restart, hot migration, deletion, and reconstruction of virtual machines.

[0054] In the related technology, network personnel log in to NFVO to make an interface call, send the lifecycle management operations of multiple VNF network elements in NS to VNFM, and VNFM parses the VNFD template of the VNF network element to perform lifecycle management on the VNF network element. Figure 1 The instantiation process of the VNF network element in the related technology is shown. For the VNF network element that has been instantiated, the operation and maintenance personnel can obtain the service performance indicators of the VNF network element from the OMC, and can also log in to the virtual machine inside the VNF network element to view the operation status of the virtual machine. However, when the virtual machine inside the VNF network element has abnormal operation conditions such as no response, blue screen of the console, and "hanging", it is impossible to restart, power on and off the virtual machine through the Linux command inside the virtual machine. The operation and maintenance personnel need to log in to each VIM one by one, query the virtual machine inside the VNF network element, and then manage the life cycle of the virtual machine through the VIM. In the case of a large number of VIM resource pools, the above-mentioned query to the virtual machine and then manage the life cycle of the virtual machine through the VIM is cumbersome, which affects the correct use of the business.

[0055] Based on this, in the embodiment of the present application, an operation entry for operating the virtual machine in the VNF network element is newly added on the NFVO, and a first request is sent to the VNFM through the NFVO to request a first operation to be performed on the first virtual machine in the first VNF ​​network element. When the NFVO receives a first response returned by the VNFM indicating that the first virtual machine can perform the first operation, the NFVO performs the first operation on the first virtual machine in the corresponding VIM. Since the NFVO is connected to multiple VIMs, when the operation status of the virtual machine in the VNF network element is abnormal, the NFVO operates the virtual machine in the corresponding VIM, which can simplify the maintenance operation process of the virtual machine and reduce the impact of the maintenance operation of the virtual machine on the business operation of the VNF network element.

[0056] The present application embodiment provides a method for operating a virtual machine, which is applicable to a MANO system, such as Figure 2 As shown, the method includes:

[0057] Step 201: Send a first request to the VNFM through the NFVO.

[0058] Among them, the first request is used to request a first operation to be performed on a first virtual machine in a first VNF ​​network element.

[0059] Step 202: When the NFVO receives the first response regarding the first request returned by the VNFM, the NFVO performs the first operation on the first virtual machine in the corresponding VIM.

[0060] The first response indicates that the first virtual machine can execute the first operation.

[0061] Here, a new operation entry for operating the virtual machine in the VNF network element is added on the NFVO. The operations that can be performed on the virtual machine based on the operation entry include one of the following:

[0062] Creating the first virtual machine;

[0063] Deleting the first virtual machine;

[0064] Starting the first virtual machine;

[0065] Stopping the first virtual machine;

[0066] Restarting the first virtual machine;

[0067] The first virtual machine is hot migrated.

[0068] When the maintenance operation is performed on the virtual machine through NFVO, a first request is sent to VNFM through NFVO, and the request specifies the operation that NFVO needs to perform, the virtual machine to be operated, and the VNF network element corresponding to the virtual machine. After receiving the first request, NFVO detects the feasibility of the operation based on the above information specified in the first request. When it is determined that the corresponding operation can be performed on the corresponding virtual machine, VNFM returns a first response to NFVO. When NFVO receives the first response, it performs the corresponding operation on the corresponding virtual machine in the corresponding VIM.

[0069] In actual application, a new interface can be added between NFVO and VNFM to implement the above virtual machine operation solution. Table 1 shows the relevant definition of the new interface:

[0070] Table 1

[0071]

[0072] Table 2 shows the parameter definition of the new interface:

[0073] Table 2

[0074]

[0075] If the operation on the virtual machine through the newly added interface is performed correctly, the newly added interface returns status code 202; if the operation on the virtual machine through the newly added interface fails, the newly added interface returns status code 404; if the VNF network element is in other states of the life cycle causing an operation conflict, the newly added interface returns status code 409.

[0076] In actual application, the northbound interface of the corresponding VIM is called by the VNFM so that the NFVO completes the maintenance operation of the corresponding virtual machine. Based on this, when the first operation is performed on the first virtual machine in the corresponding VIM by the NFVO, the method includes:

[0077] The VNFM sends a northbound interface request of the corresponding VIM to the NFVO;

[0078] The NFVO sends the northbound interface request to the corresponding VIM.

[0079] That is to say, the indirect mode is adopted here, and VNFM sends the northbound interface request of the corresponding VIM, that is, the native openstack interface request to NFVO, and NFVO forwards the northbound interface request to the corresponding VIM, so as to perform the corresponding operation on the corresponding virtual machine in the corresponding VIM based on the corresponding northbound interface.

[0080] In one embodiment, the method further comprises:

[0081] Before or after the operation is performed on the first virtual machine in the corresponding VIM through NFVO, the VNFM and the first VNF ​​network element exchange first information; wherein,

[0082] The first information represents relevant information about the NFVO performing the first operation on the first virtual machine.

[0083] Here, before and after the NFVO operates the virtual machine, information is exchanged between the VNFM and the first VNF ​​network element, including that before executing the first operation, the VNFM sends a pre-operation request for the first operation to the first VNF ​​network element, and the first VNF ​​network element returns the post-processing result of the first operation to the VNFM. After completing the first operation, the VNFM sends the corresponding post-processing request to the first VNF ​​network element, and the first VNF ​​network element returns the corresponding post-processing result to the VNFM.

[0084] In one embodiment, after performing the first operation on the first virtual machine in the corresponding VIM through NFVO, the method further includes:

[0085] VNFM sends second information to OMC; wherein,

[0086] The second information is used to notify the status change of the first VNF ​​network element.

[0087] In actual application, maintenance operations on the virtual machine in the first VNF ​​network element will involve a state change in the life cycle of the first VNF ​​network element. Therefore, after the first operation on the first virtual machine is completed through NFVO, the VNFM sends a second message to the OMC to notify the OMC that the state of the first VNF ​​network element has changed.

[0088] Through the interaction between the VNFM and the VNF network element and OMC, real-time interactive transmission of information can be achieved. Compared with the situation where information interaction is not timely when the VM is directly operated through the VIM, the impact of the operation process of the virtual machine on the business operation in the VNF network element is reduced.
