Synchronization method and system of active and standby control boards based on atca architecture

Abstract

The invention discloses a main and standby control board synchronization method and system based on ATCA architecture. The method includes: managing a service board through a BASE plane, receiving service data sent by the service processing board through a FABRIC plane of the control board, processing and In response to the service data, manage the first state machine of the service data according to the service state of the service data, and send the corresponding synchronization command to the standby control board through the BASE plane according to the change of the first state machine; The standby control board receives the synchronization command through the BASE plane, and manages the second state machine of the service data according to the synchronization type. The invention has at least the following beneficial effects: the data synchronization is triggered by the business process, which ensures that the business status and information in the main and standby control boards are consistent, effectively avoids time-consuming batch synchronization, reduces the time for smooth data transition, and the specific business is insensitive to the main-standby switchover, Improve the stability of the communication system.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and system for synchronizing active and standby control boards based on an ATCA architecture. Background technique [0002] In order to improve the stability of the communication system, the 1+1 master-slave board mechanism is becoming more and more common, which are the master master board (Master) and the standby master board (Slave). Among them, the main main control board is the core of the equipment management and business processing of the whole machine, and communicates with the external and service boards to complete the normal functions of each board in the system; and the standby main control board is only used as the main main control board. backup. When the main main control board fails, the system needs to automatically perform active-standby switchover, and the standby main control board takes over the work of the main main control board to ensure the normal ...

AI Technical Summary

Problems solved by technology

[0003]In the traditional method, the synchronization process of the main and standby control boards is mainly divided into three stages: batch backup, real-time backup and data smoothing. For systems that require frequent changes in backup data, such as application In the telecommunication network system, the business information backed up in real time is large and changes frequently, which increases the system overhead and also increases the time for data smoothing

And the smooth process needs to wait for the data and status maintained by the system to be consistent before the standby device can really become the active device. Therefore, in a system that is sensitive to delay, it cannot meet the requirements of real-time processing
