Abstract

The invention provides a method and a device for link switching and a line card. The method comprises the following steps of establishing a link between a standby main board and the line card; and sending an indication message to the line card through the link between the standby main board and the line card under the circumstance that an active main board has a fault, wherein the indication message is used for indicating the line card to switch to the link between the standby main board and the line card. Through the method and the device for link switching and the line card, a problem that the correlation technique cannot quickly carry out link switching after system switching without affecting the business is solved, so that an effect of quickly carrying out link switching without affecting the business can be realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a link switching method, device and line card. Background technique [0002] The telecommunications system has high requirements for real-time communication and business protection, so it often provides dual-machine active and standby operation at the same time. Stable and reliable business. Since the communication between the main control board and the service line card is relatively frequent, how to quickly restore the communication between the new main control board and the service line card after the active / standby switchover becomes a very important index for business stability. Business interruption due to loss of messages. [0003] Communication equipment has high requirements on business stability and real-time performance. The system architecture is generally based on active and standby protection and business distribution, so the stability of communication links is ...
