Embodiment 1

[0140] Figure 18 It is a VIM upgrade according to the embodiment of the present invention. When the VNF service is in active / standby backup, it is a schematic diagram of VNF service switching and virtual machine migration, as shown in Figure 18 As shown, a VIM system manages four physical hosts, which are HOST1, HOST2, HOST3, and HOST4. VIM's virtual machine management system resides in HOST1, in which entity 4101 is NFVO, entity 4102 is VNF controller, 4201, 4202, 4301, and 4302 are business virtual machines of the VNF, and the business relationship between 4201 and 4301 is mutual Active / standby, 4202 and 4302 are mutually active / standby in terms of business relationship, 4401 and 4402 virtual machines have not been created yet, and are created during the virtual machine migration process.

[0141] The VIM notifies 4101 that an upgrade will be performed, and the issued upgrade information is: the physical machine to be upgraded is HOST2, and the virtual machines residing o...

Embodiment 2

[0151] Figure 19 According to the VIM upgrade according to the embodiment of the present invention, when the VNF business is active / standby backup and load sharing mode, the schematic diagram of VNF business switching, migration and virtual machine migration, as shown in Figure 19 As shown, a VIM system manages four physical hosts, which are HOST1, HOST2, HOST3, and HOST4. VIM's virtual machine management system resides in HOST1, in which entity 5101 is NFVO, entity 5102 is VNF controller, 5201, 5202, 5301, and 5302 are business virtual machines of the VNF, and the business relationship between 5201 and 5301 is load sharing , the business relationship between 5202 and 5302 is in master / backup mode, 5202 is master, 5302 is backup, 5401, 5402 virtual machines have not been created yet, and are created during virtual machine migration.

Embodiment 3

[0162] Figure 20 It is a VIM upgrade according to the embodiment of the present invention. When the VNF has a virtual machine in a service failure state, a schematic diagram of VNF service switching and virtual machine migration, as shown in Figure 20 As shown, a VIM system manages four physical hosts, which are HOST1, HOST2, HOST3, and HOST4. VIM's virtual machine management system resides in HOST1, in which entity 6101 is NFVO, entity 6102 is VNF controller, 6201, 6202, 6301, and 6302 are business virtual machines of the VNF respectively, and the business relationship between 6201 and 6301 is mutual Active / standby, 6202 and 6302 are mutually active / standby in terms of business relationship. The 6302 virtual machine fails and cannot run services. The 6401 and 6402 virtual machines have not been created yet, and are created during the virtual machine migration process.

Abstract

The present invention provides a physical machine upgrade method, service migration method and device. The physical machine upgrade method includes: receiving an upgrade request sent by a virtualized infrastructure management VIM, wherein the upgrade request is used to request to upgrade a first physical machine, One or more first virtual machines reside on the first physical machine; perform the process of migrating services running on one or more first virtual machines to one or more second virtual machines according to the above upgrade request; After the processing is completed, send a migration message for migrating one or more first virtual machines to one or more third virtual machines to the VIM; receive the migration result returned by the above-mentioned VIM; according to the above-mentioned migration result, notify the VIM to execute the first A physical machine upgrade process. The present invention solves the problem in the related art that when the VIM is upgraded, the operation of the service will be interrupted, thereby achieving the effect of realizing the VIM upgrade under the condition of ensuring that the service is not interrupted.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method for upgrading a physical machine, a method and a device for service migration. Background technique [0002] In traditional network devices, software and hardware are provided by one device, and Network Functions Virtualization (NFV for short) is to change this, that is, software and hardware need to be separated, so that software and hardware are independent develop. The research goal of the NFV working group is to widely adopt standardized virtualization technology, adopt industry-standard large-capacity servers, storage and switches to carry various network software functions, realize flexible loading of software, and realize virtualization in data centers, Flexible deployment and configuration of various locations such as network nodes and user terminals, thereby speeding up network deployment and adjustment, reducing the complexity of service deployment, improvin...
