Main and standby control board synchronization method and system based on ATCA architecture

Abstract

The invention discloses a main and standby control board synchronization method and system based on an ATCA architecture. The method comprises the following steps: managing a business board through aBASE plane; receiving service data sent by a service processing board through an FABRIC plane of a control board; processing and responding to service data, managing a first state machine of the service data according to the service state of the service data, and sending a corresponding synchronization command to a standby control board through a BASE plane according to the change condition of a first state machine; and enabling a standby control board to receive the synchronization command through the BASE plane and manage a second state machine of the service data according to the synchronization type. The invention at least has the following beneficial effects that data synchronization is triggered by a service process, the service state and information consistency in the main and standby control panels is ensured, the batch synchronization time consumption is effectively avoided, the data smooth transition time is reduced, the specific service is non-inductive to main and standby switching, and the stability of a communication system is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for synchronizing active and standby control boards based on the ATCA architecture. Background technique [0002] In order to improve the stability of the communication system, the 1+1 main and standby board mechanism is becoming more and more common, which are respectively the main main control board (Master) and the standby main control board (Slave). Among them, the main main control board is the core of 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; while the standby main control board is only used as the main main control board backup. When the active main control board fails, the system needs to automatically switch between the main and standby main control boards, and the standby main control board takes over the work of the ...

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
