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

摘要

The present invention discloses an active and standby switching interface module, a network element system and a method for synchronizing and detecting link information. In the scheme of the present invention, the standby switching function interface module sends a synchronization detection request message to a synchronization module, and performs synchronization processing on the link information on the standby switching function interface module according to a synchronization detection reply message from the synchronization module, wherein the synchronization detection reply message encapsulates the link information on the active switching function interface module. The scheme provided by the present invention effectively performs the synchronization and consistent detection on the link information, thereby correctly switch the data on the active switching function interface module to the link of the standby switching function interface module when the active switching function interface module is required to perform the active and standby switching due to problems such as the failure and so on.
