In order to improve the reliability of data transfer, WTD is received after file identification message, sends file confirmation message extremely
BO, UID and start byte that file confirmation message is included validating that.
In theory, the UID of confirmation here and the start byte of confirmation should include file with file identification message respectively
UID be with start byte as, if different, WTD will not to BO send fault data file.
Preferably, file identification message also includes maximum load；
Then accordingly：
The maximum load that file confirmation message is also included validating that；
The method also includes：
Fault data file is divided into multiple blocks of files by WTD according to maximum load, and sends blocks of files successively；
When fault data file total data is sent completely, BO will be markd including the corresponding institute of fault data file
Labelling bag is sent to the process of WTD：
When a blocks of files total data is sent completely, BO will send out including the markd labelling bag of the corresponding institute of blocks of files
Deliver to WTD.
Specifically, the configuration and performance because BO ends may carry out data transmission with multiple WTD simultaneously, by its server
Limit, be that each file waiting for transmission is provided with maximum load, maximum load here shows to continuously transmit how many predetermined words
Both sides suspend transmission and confirm to have received the value of message amount after the data of section.The setting of the value of maximum load and the configuration of server
It is related.
Assume that fault data file here is 128KB, maximum load is 50KB, then WTD can be by fault data file
It is divided into 50KB, 50KB and 28KB.
Then the size of blocks of files is：Payload × preset byte.
Here payload refers to the number of times that content need to be sent by file message format in this fault data file, its
Less than or equal to the maximum load value that BO specifies, (the fault data file that corresponding usual WTD finally sends when being less than, for example, go up value
State the 28KB for mentioning).
In addition, after the data of a blocks of files have all been passed, judging whether that all transmission is correct, if it is, carrying out again
The transmission of next blocks of files.Otherwise, the data of loss are resend into again one time.
Specifically, for the form of initial message, refer to table 1：
The initial message table of table 1
BO is received after initial message, and to WTD file identification message, the form such as table 2 of file identification message are sent：
The file identification message table of table 2
WTD is received after file identification message, sends file confirmation message to BO, specifically, the lattice of file confirmation message
Formula such as table 3：
The file confirmation message table of table 3
| Message numbering | Message length | Message version | UID | Start byte | Maximum load confirms |
| 2Bytes | 2Bytes | 1Byte | 2Bytes | 5Bytes | 2Bytes |
BO will be sent to WTD including the markd labelling bag of the corresponding institute of blocks of files, and the form of labelling bag here is：
The labelling bag table of table 4
Complete flag data and refer to the quantity that BO has been properly received data, complete marker number and have recorded fault data text
The corresponding labelling of data of all preset bytes in part or blocks of files.
WTD starts according to start byte and unfinished labelling, by the fault data block data corresponding to unfinished labelling
File message is packaged into, and is transmitted by following file message format, 1KB data volumes (predetermined word joint number, file are sent every time
In content field), the form of file message is：
The file message table of table 5
| Message numbering | Message length | Message version | UID | Start byte | Payload | File content |
| 2Bytes | 2Bytes | 1Byte | 2Bytes | 5Bytes | 2Bytes | 1024Bytes |
After WTD completes the file message of all unfinished labelling correspondence fault datas, WTD is supplemented and is sent frame control report
Text shows that this file block is transmitted.
Table 6 controls message table
| Message numbering | Message length | Message version | UID | Code |
| 2Bytes | 2Bytes | 1Byte | 2Bytes | 1Byte |
After BO is received, transmission band completes the labelling bag of labelling and is sent to WTD, wherein, complete marker number and show ground
The state of received server-side message, if the payload bit value of the numbering is 1 shows that data have all been received correctly,
The transmission of next blocks of files is carried out until All Files piecemeal is transmitted.Otherwise WTD is retransmitted to be had before labelling packet making field
Fault data file in effect load byte corresponding to 0.
Preferably, the method also includes：
After a blocks of files has been sent, the quantity for calculating the data for completing labelling according to labelling bag accounts for place file to WTD
The ratio of the quantity of all data of block, and proportionally change transmission rate when sending next blocks of files.
If it is understood that ratio is 1, illustrating that all data are marked, i.e., all data are properly received,
Illustrate that now channel is more unobstructed, now can advance the speed to send next blocks of files, otherwise, illustrate that now channel is obstructed
Freely, can now keep or reduce the next blocks of files of transmission.
Preferably, the process for proportionally changing transmission rate when sending next blocks of files is specially：
When ratio is 1, WTD advances the speed and sends next blocks of files；
When ratio is more than predetermined threshold value and during less than 1, WTD keeps speed to send next blocks of files；
When ratio is less than predetermined threshold value, WTD reduces speed and sends next blocks of files.
Preferably, predetermined threshold value is 80%.
Certainly, predetermined threshold value here can also be other numerical value, and here of the present invention is not particularly limited, according to reality
Situation is determining.
Preferably, when the data of the fault data file of preset byte are correctly received then, marker number is completed
In reference numeral be 1, when the data of the fault data file of preset byte are not correctly received then, complete marker number
In reference numeral be 0.
By maximum load the method that the present invention is provided is described as a example by 100 below：
WTD is received after the file identification message of BO, sends file confirmation message to BO, and UID and maximum load are carried out
Confirm, and start byte 0 is sent to into BO.
BO feedback flag bags, this labelling bag sends No. UID of file, and confirms that file block start byte is 0, and maximum is negative
Carry as 100, complete marker number for 0, complete marker number for 100 0 (because now also not starting to transmit file).
WTD is received after initial labelling bag, and from the beginning of blocks of files start byte, control receives and mark is completed in labelling bag
Note position is the start byte corresponding to 0, sends file message.
After transferring the file message of 100 preset bytes, WTD sends control message and gives the BO (codes in control message
Row define a code and represent that this file block is transmitted).
BO will be carried and be completed the labelling bag of marker number and be sent to WTD, wherein complete marker number for payload (with
As a example by 100) number that has been received by individual file message (if 100, then it represents that the file message of all transmissions has been received by.
If being less than 100 (if for example, 80), represent in transmitting procedure, there are 20 file messages to lose, the document location of loss
It can be seen that complete marker number (100 0 and 1 sequence, 1 represent receive, 0 represent do not receive).WTD completes mark for labelling bag
Remember the file data that position is 0, again resend 20 unreceived file messages, and send control message and represent this text
Part piecemeal is transmitted.It is 100 that WTD and BO will steps be repeated alternatively until that BO feedbacks complete marker number, and completes labelling
In be 1 per 1.
