Changed data inside standby data generating module.
Preferably, according to the organizational form of business datum, index corresponding with the business datum is generated.
202, being indexed in preset cache structure for control unit preservation business datum is sent.
Wherein, preset cache structure includes at least: fifo queue and tree structure.Specifically, caching the business
When the index of data, storage is combined according to following two mode:
The first storage mode: it is stored according to the sequence in a manner of fifo queue for getting business datum；
Storage mode in second: index is stored according to tree structure.
It further, can be according to other storage rules of user or default come the index of storage service data.
It is worth noting that business datum can be guaranteed according to the sequence got when using the first storage mode
It is successively sent to the receiving end of business datum, to simplify the processing logic that business datum sends control with scheduling；Work as use
When second of storage mode, when removing specific index data, the search efficiency of the index of the business datum can be improved.
203, when detecting that communication channel allows to send business datum, according to the index of the business datum to be sent of caching
It obtains business datum to be sent, and generates new data to be sent, by communication channel, send and new pending transmit data to reception
End equipment.
It is worth noting that being sent in data procedures to be sent, further includes: following three kinds of situations by communication channel:
The first situation: when the data generating unit of data producer module carries out twice identical business datum to be sent
Or when multi-pass operation, due to for each time operate can all send the business datum to be sent to index transmission control single
Member sends the index that control unit only retains the business datum to be sent that data generating unit last time is sent.
Specifically, the corresponding control unit that sends will receive simultaneously when carrying out multi-pass operation to same a business datum
The index for caching the business datum to be sent of number corresponding with the number of operations of the business datum, will basis if be not processed
Multiple index gets business datum identical with the multiple groups of equivalent amount of index number of above-mentioned business datum, so
At this moment the index for the multiple identical business datums for needing to cache is deleted, and the index of the business datum is only retained, thus
Only retain one group of business datum to be sent, and the business datum of the reservation is sent to data transmission module.
Second situation: when service data manipulating to be sent variation, the data generating unit root of data producer module
It is different according to the operation of business datum to be sent, generate additional information；And the business to be sent generated according to business datum to be sent
The index of additional information and business datum to be sent is sent to transmission control unit by the index of data together；Data producer
The transmission control unit of module is generated and is sent by communication channel according to the additional information and the business datum to be sent of acquisition
New data to be sent.Send index and additional information that control unit receives business datum to be sent from data generating unit
Afterwards, when judging to preserve the index of identical business datum to be sent in preset cache structure, with currently received attached
Add the corresponding additional information of index of the business datum to be sent saved in information update preset cache structure.
Wherein, additional information is used to record the operational order or operation change to current business datum to be sent.Work as data
When generation unit modifies identical business datum to be sent twice, data generating unit is by additional information and according to be sent
The index for the business datum to be sent that business datum generates together, is sent to transmission control unit；Data generating unit according to
The index and tree-like buffer structure for sending business datum, quickly find in tree structure on present in preset cache structure
The index of primary business datum to be sent, and deleted from fifo queue and tree structure.Control unit is sent only to retain
The index for the business datum to be sent that data generating unit last time is sent.
When data generating unit is first added identical business datum to be sent, deletes afterwards, data generate single
The index of the relevant additional information of delete operation and business datum to be sent together, is sent to transmission control unit by member；It sends
Control unit quickly finds preset cache according to the index and tree-like buffer structure of business datum to be sent in tree structure
The index of the business datum to be sent of last time present in structure, and deleted from fifo queue and tree structure.If
It deletes successfully, sends the index that control unit does not retain business datum to be sent.
The change that current data occurs relative to the data of original storage, and then can be only to the changed a part
Data are handled.For example, the variation that business datum occurs are as follows: be added to data on the basis of original business datum, then root
Additional information is generated according to the data of the addition, wherein description has which number is added in the business datum in the additional information
According to, and then data described in upper additional information can be directly added on the index of the business datum of original caching, it constitutes most
Whole task data to be sent, buffered business datum before need not reacquiring again in this case have saved and are
System resource.
It is worth noting that a kind of above-mentioned only citing changed to business datum, the embodiment of the present invention is to business
The version of data is without limiting.
The third situation: when detecting communication channel exception, the index of specified services data is removed.
It is worth noting that in the first scenario, it is complete that storage is avoided in the sending ending equipment of business datum
Business datum and multiple storage to same a business datum, to reduce the waste of system resource.In the latter case,
It avoids in the same business datum of caching, when executing addition, delete operation to same a business datum, if adding or deleting
The operation service data removed are identical, can thus make data receiver first add and delete the business datum again, in this way in business
The receiving end of data executes useless action, wastes system resource.
