Communication device and active-standby system data online exchange method for hot master control panel backup

Abstract

The invention discloses a communication device and an active-standby system data online exchange method for a hot master control panel backup. The active-standby system data online exchange method is applied to the communication devices of active and standby systems with a master control panel and a business board, and the active-standby system data online exchange method comprises the following steps of: transmitting business operation data to the master control panel of the active system by the business board of the active system via the communication module between boards; synchronizing any business operation data of the active system into the master control panel of the standby system by the hot backup module of the active system; confirming the attribution of the business operation data and in real time updating the data of the module involving in the business operation data from the business card of the standby system by the master control panel of the standby system. The technical solution of the invention can ensure that data between the active system and the standby system can be in real time synchronized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication device and a method for on-line exchange of master and backup system data in hot backup of a main control board. Background technique [0002] In the field of data communication, high-end distributed network equipment (such as high-end switches and routers) is in a very important position, no failure is allowed, and even if a failure occurs, in order to ensure the reliability of equipment and networks, a backup mechanism is generally required . The main control board and service board are designed for distributed products. The main control board controls the operation of the entire network equipment, and the service board is responsible for data forwarding. In order to improve the reliability of network equipment, the hot backup mechanism is designed so that all sectors are equally backed up 1:1, one system is in working state, and the other is in standby s...
