[0002] Network Function Virtualization (NFV) refers to network functions deployed and running on a telecom cloud platform. The resources used by network functions are managed by a Management and Orchestration (MANO) system, which consists of three subsystems, namely a NFV Orchestrator (NFVO), a Virtualized Network Function Manager (VNFM), and a Virtualized Infrastructure Manager (VIM). The infrastructure of a telecom cloud platform (Network Function Virtualization Infrastructure (NFVI)) consists of physical machines (including a master node and physical machines managed by the master node), network devices, and cloud system software. After network function virtualization, how to ensure that the normal operation of network functions running on the cloud platform is not affected during the upgrade of physical machines is a major problem faced by telecom clouds and network function virtualization.

[0064] The steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And, although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0065] See Figure 1 , an embodiment of the present invention proposes an upgrade method, including:

[0066] Step 100: Determine N physical machines to be upgraded, where N is an integer greater than or equal to 1.

[0067] Step 101: For each physical machine, migrate the services of the network elements of the virtual machines on the physical machine, evacuate the virtual machines on the physical machine to other physical machines, upgrade the physical machine, and notify the Network Function Virtualization Infrastructure (NFVI) to incorporate the upgraded physical machine into management and application.

[0070] The above steps for different physical machines are independent of each other and do not affect each other. The above steps for different physical machines can be run in parallel, or after the above steps are completed on one physical machine, the above steps of another physical machine can be executed.

[0071] In another embodiment of the present invention, determine the upgrade order, and for each physical machine in sequence according to the upgrade order, migrate the services of the network elements of the virtual machines on the physical machine, evacuate the virtual machines on the physical machine to other physical machines, upgrade the physical machine, and notify the Network Function Virtualization Infrastructure (NFVI) to incorporate the upgraded physical machine into management and application.

[0077] Among them, the NFVI is the master control node of all physical machines, on which a cloud platform runs.

[0078] In an embodiment of the present invention, upgrading a physical machine includes: sending an upgrade request to the physical machine; receiving the third response task completion of the physical machine.

[0079] Among them, an upgrade agent can be set in the physical machine to implement the upgrade of the physical machine, that is, receive the upgrade request, download the new version and upgrade the physical machine, and send the third response task completion.

When one execution process corresponds to each physical machine, it is considered that the migration of the services of the network elements of the virtual machines on the N physical machines is completed only when the first reply tasks of the N physical machines are received and completed.

[0107] In the embodiment of the present invention, evacuating the virtual machines on the N physical machines to other physical machines includes:
