Abstract
A method includes: a first node monitors a status of a connection between the first node and a center system, and switches to the standby node working mode when the status of the connection between the first node and the center system is disconnected. The center system monitors a status of a connection between the center system and the first node, and sends a switch-to-master command to a second node when the status of the connection between the center system and the first node is disconnected. The second node switches to the master node working mode based on the switch-to-master command. Accordingly, whether a master node is switched to a standby node is determined through connectivity detection between the node and the center system, and whether a standby node is switched to a master node is determined based on an indication of the center system.
