Single plate master and slave switching method in cut-in layer device

Abstract

The invention provides a single-desk switching method in the access layer equipment, its core: mainframe side of access layer device determines it needs to process the main node single-desk switching of the access side, and sends switching information to the reserved main node single-desk , the mainframe side shields fault information reported form user plate of access side in the scheduled interval, after receiving the switching information, the standby node single-desk switches to the host main node single-desk. The invention avoids the dropping of users to a certain extent during reduction process of all users' plate on access side. In addition it also avoids unnecessary alarm information appearing in the maintenance of the terminal, and reduces maintenance workload of the access layer equipment.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for switching master and backup of a single board in an access layer device. Background technique [0002] In the field of access network, since user dropped calls will directly affect users' satisfaction with call quality, how to reduce the downtime of network equipment to reduce the occurrence of user dropped calls has always been a matter of great concern in the industry. [0003] In the current field of access network, the protection of the call function of the user is usually realized by means of a backup master node board provided for the master node board in the user frame. The implementation process of switching between the main node single board and the backup main node single board is shown in Fig. 1 . [0004] In Figure 1, when the master node board fails, or a communication failure occurs between the master node board and the host, and the host...

Problems solved by technology

[0005] It can be seen from the above-mentioned master-standby switchover process that since the standby master node board takes over from the original master node board to establish connections with user boards, the master-standby switchover process will be accompanied by the reset of all user boards in the entire user frame , although the master-standby switching process takes a short time, it will inevitably lead to the disconnection of all online users in the user frame, which reduces user satisfaction; at the same time, the reset of a large number of user boards will cause the equipment management center to receive a large number of User board failure alarms need to be confirmed one by one by maintenance personnel, which increases the workload of access layer device maintenance
