The cloud computing end sends to the cloud client with the synchronizing information packet that assembling obtains, so that the cloud client is carried out Synchronous Processing to local data.
9. like claim 7 or 8 described information synchronization methods, it is characterized in that, also comprise:
The cloud computing end carries out collision detection to the synchronous element that explanation obtains;
When detecting when clashing, the cloud computing end obtains the result of conflicting according to the processing that conflicts of information synchronization strategy;
The cloud computing end is carried out Synchronous Processing to the cloud client in the data of cloud computing end according to said conflict result, obtains the Synchronous Processing result;
The cloud computing end generates synchronous element according to said Synchronous Processing result, and the synchronous element that will generate is assembled into the synchronizing information packet.
10. an information synchronization method is characterized in that, comprising:
The cloud client is according to the information synchronization process of information synchronization strategy startup with the cloud computing end;
After the information synchronization process started, the cloud client was extracted the lastest imformation of cloud client data from the cloud client, generate synchronous element according to said lastest imformation, and said synchronous element is assembled into the synchronizing information packet;
The cloud client sends to the cloud computing end with said synchronizing information packet, so that the cloud computing end is carried out Synchronous Processing to the cloud client in the data of cloud computing end.
11. information synchronization method as claimed in claim 10 is characterized in that, also comprises:
The cloud client receives the synchronizing information packet that the cloud computing end sends;
The cloud client makes an explanation to the synchronizing information packet that receives, and obtains synchronous element;
The cloud client is carried out Synchronous Processing according to the synchronous element that explanation obtains to local data.
12. information synchronization method as claimed in claim 11 is characterized in that, also comprises:
The cloud client is carried out collision detection to the synchronous element that explanation obtains;
When detecting when clashing, the cloud client obtains the result of conflicting according to the processing that conflicts of information synchronization strategy;
The cloud client is carried out Synchronous Processing according to said conflict result to local data, obtains the Synchronous Processing result;
The cloud client generates synchronous element according to said Synchronous Processing result, and the synchronous element that will generate is assembled into the synchronizing information packet.
