MAIN/STANDBY SWITCHING INTERFACE MODULE, NETWORK ELEMENT SYSTEM, AND LINK INFORMATION SYNCHRONIZATION DETECTION METHOD

摘要

The present invention discloses a main/standby switching interface module, a network element system, and a link information synchronization detection method. In the solution of the present invention, the standby switching function interface module sends a synchronization detection request message to a synchronization module, and performs the synchronization processing on the link information on the standby switching function interface module according to the synchronization detection response message from the synchronization module, wherein the link information on the main switching function interface module is encapsulated in the synchronization detection response message. According to the solution provided by the present invention, the synchronization and consistency detection of link information can be effectively performed, and thereby the data on the main switching function interface module can be correctly switched to the link of the standby switching function interface module when the main/standby switching is needed due to the problem that a failure occurs on the main switching function interface module, and the like.
