Embodiment
Basic thought of the present invention is: GSPC card business module backs up registration to the backup module of self place Slave Processing Unit, controls GSPC card business module by the backup module of place Slave Processing Unit and backs up; Further, the Backup Data of GSPC card can directly transmit between GSPC master is with card and GSPC standby card.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is further detailed explanation below in conjunction with accompanying drawing.
Referring to Fig. 3, GSPC card business module mainly comprises following step to the process that the backup module of self place Slave Processing Unit backs up registration among the present invention:
Step 301:GSPC card business module sends register requirement to the backup module of self place Slave Processing Unit;
The registration function that the business module of Slave Processing Unit self can directly call self backup module backs up registration, but the GSPC card is the plug-in card on the Slave Processing Unit, and the registration function that GSPC card business module can not directly be called the Slave Processing Unit backup module backs up registration.Owing to can directly carry out the message communication by communication channel between plate between GSPC card and the Slave Processing Unit, therefore, GSPC card business module can send register requirement to the backup module of GSPC card self place Slave Processing Unit by communication channel between plate.
Step 302: described Slave Processing Unit backup module provides registration function to GSPC card business module after receiving register requirement;
The registration function that step 303:GSPC card business module invokes self place Slave Processing Unit backup module provides backs up registration.
The backup module of GSPC card place Slave Processing Unit is after GSPC card business module provides registration function, GSPC card business module can be as the business module of Slave Processing Unit self, the registration function of calling the Slave Processing Unit backup module backs up registration, and GSPC card business module is similar to the backup registration process that the backup module of self place Slave Processing Unit backs up the process of registration and existing Slave Processing Unit own service module.
After above backup registration process is finished, GSPC card business module just can be regarded as the business module of GSPC card place Slave Processing Unit, when needs backed up, unified backup module by Slave Processing Unit notified the business module and the GSPC card business module of Slave Processing Unit self to back up by the backup control messages.Referring to Fig. 4, the solid line between Slave Processing Unit backup module and Slave Processing Unit business module and the GSPC card business module represents to back up the transmission channel of control messages.
As can be seen from Figure 1, Backup Data transmission between SPU main board and the SPU standby plate is all undertaken by backup module, correspondingly, the Backup Data of GSPC card also can be by the backup module transmission of Slave Processing Unit, but because actual needs backed up data amount is bigger, if GSPC master with the Backup Data between card and the GSPC standby card also via the backup module of Slave Processing Unit, then will certainly influence the communication bandwidth between Slave Processing Unit and the GSPC card, and because GSPC master is with can directly carrying out communication by network processing unit between card and the GSPC standby card, therefore, for the transfer resource that reduces between Slave Processing Unit and GSPC card takies, GSPC master can receive directly exchange backed up data of backup notice back with card and GSPC standby card, be that GSPC master can directly carry out by network processing unit with the Backup Data transmission between card and the GSPC standby card, and need not be again by the backup module of Slave Processing Unit, efficient is higher like this.The activestandby state of GSPC card is consistent with the activestandby state of place Slave Processing Unit, and promptly the GSPC card on the SPU main board is that GSPC master uses card, and the GSPC card on the SPU standby plate is the GSPC standby card.Referring to Fig. 4, the solid line of band arrow is represented the transmission channel of Slave Processing Unit Backup Data between SPU main board backup module and the SPU standby plate backup module, GSPC master represents the transmission channel of GSPC card Backup Data with the solid line of band arrow between card and the GSPC standby card, the Backup Data that is the GSPC card directly transmits between GSPC master is with card and GSPC standby card, and no longer the backup module by Slave Processing Unit transmits.
The above business module backs up registration and backup module control business module carries out data backup to backup module, all at GSPC master with blocking and the SPU main board.
If there are a plurality of business modules on the GSPC card, then each business module can adopt said method to back up.
As seen, the present invention effectively utilizes the data backup that the Slave Processing Unit backup module has been realized the GSPC card, need not to add backup module on the GSPC card, has guaranteed the service feature of GSPC card.
The above has carried out further detailed description to purpose of the present invention, technical scheme and beneficial effect; institute is understood that; the above is not in order to restriction the present invention; within the spirit and principles in the present invention all; any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
