Application data migration method and network device

A network device, comprising:

• an interface;
• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• obtain a first parameter, a second parameter, and a third parameter, wherein the first parameter comprises a delay in communication between a terminal device and a first server through a first connection, the second parameter comprises a delay in communication between the terminal device and a second server through a second connection, and the third parameter comprises a time for synchronizing a context between the first server and the second server;
• if the first parameter is greater than a sum of the second parameter and the third parameter, determine that application data on the terminal device needs to be migrated from the first connection to the second connection;
• and
• if the first parameter is not greater than the sum of the second parameter and the third parameter, determine that application data on the terminal device does not need to be migrated from the first connection to the second connection.
