Abstract

The invention provides a main and standby equipment switching method and device. The main and standby equipment switching method is applied to network equipment, and comprises the following steps: when first equipment works as main equipment, if all links between the equipment and opposite-end equipment are detected to be abnormal, the equipment priority of the network equipment is adjusted from afirst priority value to a second priority value, wherein the second priority value is smaller than a third priority value, the third priority value is the equipment priority of the second equipment,and the second equipment works as standby equipment at present; a heartbeat message is sent to the second equipment, wherein the heartbeat message carries a second priority value, so that the second equipment is switched from standby equipment to main equipment according to the second priority value; and the equipment is switched from the main equipment to the standby equipment according to the second priority value.

Description

technical field [0001] The present application relates to network communication technology, and in particular to a method and device for switching between active and standby equipment. Background technique [0002] As the scale of the network becomes larger and the traffic in the network becomes more and more diverse, the performance requirements for network devices become more stringent. Nowadays, with the increase of network scale, for enterprises and operators, traffic interruption at any moment will cause immeasurable losses. Therefore, a network device in a standby state is usually set up in the networking to switch to the active state when an active / standby switchover is required, and replace the original active device to complete traffic processing. [0003] At present, the active network device usually sends heartbeat packets periodically to the backup network device. After the backup network device does not receive the heartbeat message sent by the active network d...
