Abstract
The invention relates to a method for realizing data synchronization between a main control board and a standby main control board, comprising a cyclic backup and a manual synchronization. For the cyclic backup, the way of timing synchronization is adopted in the main control board, when a data synchronizing cycle is reached, the main control board can synchronize all data that need to be backed up presently to the standby main control board; for the manual synchronization, for compensating the inconformity of data caused by various factors, a manual instruction can be given to ensure that the main control board can synchronize all data that need to be backed up presently to the standby main control board, particularly, when the main control board and the standby main control board are switched with each other manually, the method can ensure that the system can still run normally, stably and reliably after the switching between the main control board and the standby main control board. Compared with the prior art, as the method of the invention compensates the reliability of the data synchronization technology with various forms of the original process, reliable warm backup of data between the main control board and the standby main control board can be realized, thus enhancing the reliability and stability of the whole communication system.
Description
Technical field
The present invention relates to a kind of a kind of method of data synchronization that the 1+1 hot backup function adopts of in communication system, realizing; It can realize making under the situation that data at the work mainboard change; Make the backup plate to be consistent, thereby improve the reliability and stability of system with the main board data in real time.
Background technology
In the optical communication system, especially core net because its network site of living in is extremely important, does not allow to occur Single Point of Faliure in modern times, and equipment generally all is equipped with two master control borads, is called main control board (Master) and slave control board (Slave) respectively.Wherein, main control board carries out service communication, the normal function of each module in the completion system as the core of control plane with outside and business board; Slave control board then only as the backup of main control board, is not communicated by letter with business board with outside.When main control board broke down, system carried out active and standby switching automatically, took over the work of main control board by slave control board, guaranteed professional normal operation.And the key of guaranteeing the reliable and stable operation of said system be reach active and standby between the Hot Spare of data.The traditional data method for synchronous mainly comprises the Hot Spare that starts synchronously and reach data in real time synchronously,
Although these two kinds of methods can realize most of data sync; But these synchronous prerequisites all are to be based upon synchronous mouth and not have under the prerequisite of fault; If synchronous mouth has problem in the start-up course, synchronous mouthful fault perhaps appears, though carried out synchronously in logical running; But do not reach synchronous effect, cause synchronization failure.
Summary of the invention
It is not enough that the problem that the present invention need solve is to overcome traditional data method of synchronization synchrodata reliability, proposes the mode of two kinds of data sync, can increase the reliable synchronization of data.
First kind is periodic backups, and mainboard adopts regularly synchronous mode, and when arriving data sync during the cycle, main control board can all be synchronized to slave control board with the current backed up data that needs; It may further comprise the steps:
Step 1, plank begin after powering on and bringing into operation, the counter of at first zero clearing periodic synchronous;
Whether step 2, whenever to detect oneself at a distance from one second be mainboard, if, execution in step 3, otherwise zero clearing coincidence counter, continuation execution in step 2.
Whether step 3, detect on the thronely to plate (slave board), if then the value of coincidence counter adds one, execution in step 4, otherwise zero clearing coincidence counter continue execution in step 2.
Whether the value of step 4, the current coincidence counter of detection equals synchronizing cycle, if, just carry out data sync, send portion to all synchrodatas to slave board, execution in step 2, otherwise zero clearing coincidence counter continue execution in step 2.
Second kind is manual synchronization; In order to remedy the inconsistent phenomenon of data that causes owing to various factors; Can make main control board that the current backed up data that needs all is synchronized to slave control board through the mode of manual transmitting order to lower levels, especially manually masterslave switchover the time; Can guarantee like this after the active and standby switching that system still can the normal and stable reliability service.It may further comprise the steps:
Step 1, whenever at a distance from 10 milliseconds of detections whether the manual data synch command is arranged once, if having, then execution in step 2, otherwise continue execution in step 1.
Whether step 2, to detect oneself be mainboard, if, just carry out data sync, send all synchrodatas a to slave board.Otherwise execution in step 1.
Adopt the method for the invention; Compared with prior art; Because this method has remedied the reliability of data synchronization technology multi-form in the original process, reached active and standby between the effect of reliable Hot Spare of data, improved the reliability and stability of whole communication system.

Embodiment
To combine accompanying drawing and embodiment that technical scheme of the present invention is explained in more detail below.
, may further comprise the steps with the method that the periodic synchronous explanation the present invention relates at this:
Step 1, plank begin after powering on and bringing into operation, the counter of at first zero clearing periodic synchronous;
Whether step 2, whenever to detect oneself at a distance from one second be mainboard, if, execution in step 3, otherwise zero clearing coincidence counter, continuation execution in step 2.
Whether step 3, detect on the thronely to plate (slave board), if then the value of coincidence counter adds one, execution in step 4, otherwise zero clearing coincidence counter continue execution in step 2.
Whether the value of step 4, the current coincidence counter of detection equals synchronizing cycle, if, just carry out data sync, send portion to all synchrodatas to slave board, execution in step 2, otherwise zero clearing coincidence counter continue execution in step 2.
, may further comprise the steps with the method that the manual synchronization explanation the present invention relates at this:
Step 1, whenever at a distance from 10 milliseconds of detections whether the manual data synch command is arranged once, if having, then execution in step 2, otherwise continue execution in step 1.
Whether step 2, to detect oneself be mainboard, if, just carry out data sync, send all synchrodatas a to slave board.Otherwise execution in step 1.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
