Communication device and main/standby switchover method thereof

Abstract

Provided are a communication device and active / standby switchover method thereof, the communication device comprising a line card, an active main control board, and a standby main control board. The line card is connected to the active main control board and the standby main control board respectively via two ports; the line card comprises a switchover detection module and a switchover processing module; the switchover detection module is configured to detect whether an active / standby switchover is triggered, and transmit a switchover notification to the switchover processing module upon the detection of the trigger of the active / standby switchover; the switchover processing module is configured to add, during initialization, the port connecting the line card to the active main control board into a specified logical port group, such that the source port of an MAC address learned by the downlink data on the line card is the logical port group; and the switchover processing module is configured to delete the port connecting the line card to the active main control board from the logical port group upon receipt of the switchover notification, and add the port connecting the line card to the standby main control board into the logical port group. The present invention greatly improves user satisfaction for service experience.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication device and an active / standby switching method thereof. Background technique [0002] Communication equipment (such as OLT in optical access equipment) is generally composed of chassis, backup board, power card, main control board, line card, and uplink board. The task of the main control board is business exchange, Convergence and centralized control, while the line card is responsible for the realization of specific business requirements or functions. [0003] In order to improve the reliability of communication equipment, the main control board often adopts the active and standby mechanism. In the active / standby mechanism, there are usually two main control boards, one is the active main control board, and the other is the standby main control board. When the active main control board fails, service control and service forwarding are switched to the standby main contr...

AI Technical Summary

Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to provide a communication device and its active-standby switchover method, which solves the problems of long interruption time of uplink and downlink data and services during active-standby switchover, poor performance of system master-standby switchover, and poor user experience. The problem of low satisfaction
