Method and apparatus for in-service upgrading of network slices, and storage medium

An apparatus for in-service upgrading of network slices, which is deployed in a second device, the apparatus comprising a memory storing instructions and a processor in communication with the memory, wherein the processor is configured to execute the instructions to perform following operations:

• receiving, by the second device, version information and configuration information of respective network slices synchronized by a first device;
• when the synchronization of the version information and the configuration information is completed, performing master/standby switching between respective first slice control planes of the first device and respective second slice control planes of the second device, and performing master/standby switching between respective first slice forwarding planes of the first device and respective second slice forwarding planes of the second device;
• and
• when the master/standby switching between the first slice control planes and the second slice control planes and between the first slice forwarding planes and the second slice forwarding planes is completed, loading configuration data and performing configuration according to the configuration data by the second device, so as to complete upgrading of the second device.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program, when running on a processor on a second device, causes the processor to execute following operations:

• receiving, by the second device, version information and configuration information of respective network slices synchronized by a first device;
• when the synchronization of the version information and the configuration information is completed, performing master/standby switching between respective first slice control planes of the first device and respective second slice control planes of the second device, and performing master/standby switching between respective first slice forwarding planes of the first device and respective second slice forwarding planes of the second device;
• and
• when the master/standby switching between the first slice control planes and the second slice control planes and between the first slice forwarding planes and the second slice forwarding planes is completed, loading configuration data and performing configuration according to the configuration data by the second device, so as to complete upgrading of the second device.
