Abstract

The present disclosure discloses a service migration method including: sending, by a VNFM module, a virtual machine VM request command to a first VIM module, where the first VIM module manages a first host on which post-upgrade new-version software is configured; receiving, by the VNFM module, a VM request response from the first VIM module, where the VM request response includes information about a first VM that the first VIM module requests on the first host, and virtual machine own data that can run on the first host and that is configured by the first VIM module is configured on the first VM; and sending, by the VNFM module, a service migration command to a virtualized network function VNF module, where the service migration command is used to instruct the VNF module to migrate a running service on a second VM to the first VM.

First claim

What is claimed is:

1 . A service migration method in a network functions virtualization (NFV) architecture, the method comprising:
sending, by a virtualized network function manager (VNFM), a virtual machine (VM) request command to a first virtualized infrastructure manager (VIM), wherein the first VIM manages a first host on which post-upgrade new-version software is configured; receiving, by the VNFM, a VM request response from the first VIM, wherein the VM request response comprises information about a first VM that the first VIM requests on the first host and virtual machine data that can run on the first host and that is configured by the first VIM to run on the first VM; and sending, by the VNFM, a service migration command to a virtualized network function (VNF), wherein the service migration command is used to instruct the VNF to migrate a running service on a second VM to the first VM, and the second VM is deployed on a second host on which pre-upgrade old-version software is configured.

2 . The method according to claim 1 , further comprising:
receiving, by the VNFM, a service migration completion notification from the VNF; and after the VNFM receives the service migration completion notification from the VNF, releasing, by the VNFM, the second VM.

3 . The method according to claim 1 , wherein the second host is managed by the first VIM, and before the sending, by the VNFM, the service migration command to the VNF, the method further comprises:
sending, by the VNFM, a virtual machine query command to the first VIM, wherein the virtual machine query command instructs the first VIM to query information about the second VM that is running a service of the VNF; wherein the service migration command that is sent by the VNFM to the VNF carries the information about the second VM.

4 . The method according to claim 1 , wherein the post-upgrade new-version software is configured on the first VIM, the second host is managed by a second VIM on which the pre-upgrade old-version software is configured, and before the sending, by the VNFM, the service migration command to the VNF, the method further comprises:
sending, by the VNFM, a virtual machine query command to the second VIM, wherein the virtual machine query command instructs the second VIM to query information about the second VM that is running a service of the VNF; wherein the service migration command that is sent by the VNFM to the VNF carries the information about the second VM.

5 . The method according to claim 4 , wherein the post-upgrade new-version software configured on the first VIM and the pre-upgrade old-version software configured on the second VIM are homogeneous software or heterogeneous software.

6 . The method according to claim 1 , wherein the post-upgrade new-version software configured on the first host and the pre-upgrade old-version software configured on the second host are homogeneous software or heterogeneous software.

7 . The method according to claim 1 , wherein the sending, by the VNFM, the service migration command to the VNF comprises:
sending, by the VNFM, the service migration command to an element management system (EMS), so that the EMS forwards the service migration command to the VNF, wherein the EMS is configured to manage the VNF.

8 . A service migration method in a network functions virtualization (NFV) architecture, the method comprising:
receiving, by a virtualized network function (VNF), a service migration command from a virtualized network function manager (VNFM), wherein the service migration command comprises information about a first virtual machine (VM) that the VNFM instructs a first virtualized infrastructure manager (VIM) to request on a first host on which post-upgrade new-version software is configured, and wherein the service migration command further comprises virtual machine data that can run on the first host and that is configured by the first VIM to run on the first VM; and migrating, by the VNF according to the service migration command, a running service on a second VM to the first VM, wherein the second VM is deployed on a second host on which pre-upgrade old-version software is configured.

9 . The method according to claim 8 , further comprising:
after the VNF migrates the running service on the second VM to the first VM, sending a service migration completion notification to the VNFM.

10 . The method according to claim 8 , wherein the receiving, by the VNF, the service migration command from the VNFM comprises:
receiving, by the VNF, the service migration command that is forwarded by an element management system (EMS) from the VNFM.

11 . A service migration apparatus in a network functions virtualization (NFV) architecture, the apparatus comprising:
a transmitter; and a receiver, wherein the transmitter is configured to send a virtual machine (VM) request command to a first virtualized infrastructure manager (VIM), wherein the first VIM manages a first host on which post-upgrade new-version software is configured; wherein the receiver is configured to receive a VM request response from the first VIM, wherein the VM request response comprises information about a first VM that the first VIM requests on the first host and virtual machine data that can run on the first host that is configured to run on the first VM; and wherein the transmitter is configured to send a service migration command to a virtualized network function (VNF), wherein the service migration command instructs the VNF to migrate a running service on a second VM to the first VM, wherein the second VM is deployed on a second host on which pre-upgrade old-version software is configured.

12 . The apparatus according to claim 11 , wherein the second VM is released after a service migration completion notification from the VNF is received.

13 . The apparatus according to claim 11 , wherein the second host is managed by the first VIM, and wherein the transmitter is further configured to:
send a virtual machine query command to the first VIM, wherein the virtual machine query command instructs the first VIM to query information about the second VM that is running a service of the VNF; wherein the service migration command that is sent by a VNFM to the VNF carries the information about the second VM.

14 . The apparatus according to claim 11 , wherein the post-upgrade new-version software is configured on the first VIM, the second host is managed by a second VIM on which the pre-upgrade old-version software is configured, and wherein the transmitter is further configured to:
send a virtual machine query command to the second VIM, wherein the virtual machine query command instructs the second VIM to query information about the second VM that is running a service of the VNF; wherein the service migration command that is sent by a VNFM to the VNF carries the information about the second VM.

15 . The apparatus according to claim 14 , wherein the post-upgrade new-version software configured on the first VIM and the pre-upgrade old-version software configured on the second VIM are homogeneous software or heterogeneous software.

16 . The apparatus according to claim 11 , wherein the post-upgrade new-version software configured on the first host and the pre-upgrade old-version software configured on the second host are homogeneous software or heterogeneous software.

17 . The apparatus according to claim 11 , wherein the transmitter is configured to send the service migration command to an element management system (EMS), so that the EMS forwards the s
