Abstract:
1. An active and standby switching interface module, which is located in a network element system, the network element system further comprising a control module, the active and standby switching interface module comprising an active switching interface module and a standby switching interface module, wherein the active switching interface module comprises a first processing unit configured to, when the active and standby switching interface module is used as an active switching function interface module, directly establish/delete/modify link information according to a link establishment/deletion/modification message that is received from the control module; the standby switching interface module comprises a second processing unit configured to, when the active and standby switching interface module is used as a standby switching function interface module, send a synchronization detection request message to a synchronization module, perform synchronization processing on the link information on the standby interface module according to a synchronization detection reply message from the synchronization module, and determine whether to establish/delete/modify the link information on the standby interface module according to a synchronization detection state of the link information on the standby interface module and a type of a received message from the control module, wherein the synchronization detection reply message encapsulates the link information on the active switching function interface module, and the synchronization module is the control module and the control module comprises a memory to save link information same with the link information in the active switching function interface module; wherein, the second processing unit of the standby interface module is configured to determine whether to establish/delete/modify the link information on the standby interface module according to a synchronization detection state of the link information on the standby interface module and a type of a received message from the control module in the following way:
