As shown in Fig. 1, the invention provides a kind of dual link data transmission method based on network reliable transport protocol,
Methods described comprises the following steps
Step S101, sets a single transmission data length.
Step S102, the data cutting transmitted will be needed as one or more numbers according to the single transmission data length set
According to block.
Step S103, if last data block data length is not equal to single transmission data length, at last
Individual data block afterbody adds 0 so that its length is equal to single transmission data length.
Step S104, sets up storing between the device of data of transmission in need and the device for needing reception corresponding data
Two can reliable serially-transmitted data link.
Described storage it is in need transmission data set can be one or two so that realize two can
Link with reliable serially-transmitted data is that the device for the data for connecting a storage transmission in need and one need to receive phase
Answer the device of data.
Described dual link data transmission method, the link that can be reliable serially-transmitted data is based on tcp connections
The link of data link or reliable serially-transmitted data is the data link based on http connections, can also be reliable
The link of serially-transmitted data is people by communication equipment reads data to another person, or reliable serially-transmitted data
Link is telegraph network.
Step S105, it would be desirable to which the data length and single transmission data length of transmission, which are sent to, to be needed to receive respective counts
According to device, it is necessary to which the device for receiving corresponding data calculates the data number of blocks after cutting in step S102.
Step S106, it is long according to single transmission data successively according to order from first to last on the first data link
Degree, by data from the devices of the data for storing transmission in need to needing the device for receiving corresponding data to send, inside data block
The order of each byte is constant.
Step S107, it is long according to single transmission data successively according to the order from tail to head in Article 2 data link
Degree, by data from the devices of the data for storing transmission in need to needing the device for receiving corresponding data to send, inside data block
The order of each byte is constant.
Step S108, receives data block from two data links on the device for needing to receive corresponding data and counts.
Step S109, data number of blocks after needing the device for receiving corresponding data to receive cutting in step S102
After data block, data block is connected according to original order, and behind remove in last data block that afterbody is unnecessary 0,
Complete DRP data reception process.
Step S110 is, it is necessary to which the device for receiving corresponding data sends stop signal to the need that are stored with two data links
The device of the data to be transmitted.
Step S111, the device of the data of storage transmission in need stops hair after receiving the stop signal in step S110
Packet is sent, and cuts off the link of corresponding transmission data.
As shown in Fig. 2 instantiation
A single pair of list of the invention introduced below, one double to list, and two instantiations are reliable based on network to illustrate
The dual link data transmission method of host-host protocol.
Example 1
Assuming that needing the packet transmitted to be 64k sizes, it is long to set single transmission data according to the requirement in step S101
Spend for 4k.16 are divided into according to step S102 requirement 64k packet（64/4）Individual data block.Step S103 benefit 0
Work is not suitable for this example.In this example, it is separate unit storage transmission data set in need using Transmission Control Protocol and needs to receive
Two, the device of corresponding data can reliable serially-transmitted data link, such as Fig. 2.The requirement for being first according to S105 sends data
The total size and single transmission length of bag.Reception device is according to just can be according to data block size（64k）With segmentation length（4k）, can
Equally calculate total data block number（16）.
Data block is sent from the beginning to the end according to step S106 requirement on link 1, each byte in data block is suitable
Sequence is constant.Data block is sent to the end from tail according to step S107 requirement on link 2, also required that every inside data block
Individual byte order is constant.Assuming that the transmission rate of link 1 is very fast, totally 10 data blocks are transmitted, link 2 transmits 6.According to step
Start to receive data in rapid S108 description, reception device and count, when the device for needing to receive corresponding data receives step
Data number of blocks in rapid S102 after cutting（This example is 16）Data block after, data block is connected according to original order,
Complete DRP data reception process.
It is consistent as described in step S109.After data receiver is finished, according to step S110 requirement, it is necessary to receive corresponding data
Device device of the stop signal to the data for storing transmission in need is sent on two data links.Storage transmission in need
The devices of data receive and stop sending packet after stop signal in step S110, and cut off corresponding transmission data
Link.As step S111 descriptions are consistent.
In whole transmitting procedure, both links coordinate automatically, and the property caused by link-speeds are inconsistent can be made up automatically
The loss of energy, is maximized efficiency of transmission.
Example 2
Assuming that needing the packet transmitted to be 59K sizes, it is long to set single transmission data according to the requirement in step S101
Spend for 4k.15 are divided into according to step S102 requirement 59K packet（59/4 carry is rounded）Individual data block.Because most
The size of latter data block wants supplement 0 also big for 4k to the 15th data block less than 4K according to step S103.In this example,
For two storage transmission data sets in need, two, device for receiving corresponding data using http protocol and needing can
By the link of serially-transmitted data, such as Fig. 3.The total size and single transmission for being first according to S105 requirement transmission packet are long
Degree.Reception device is according to just can be according to data block size（59k）With segmentation length（4k）, can equally calculate total data block number
（15）.
Data block is sent from the beginning to the end according to step S106 requirement on link 1, each byte in data block is suitable
Sequence is constant.Data block is sent to the end from tail according to step S107 requirement on link 2, also required that every inside data block
Individual byte order is constant.Assuming that the transmission rate of link 1 is slower, totally 4 data blocks are transmitted, link 2 transmits 11.According to step
Start to receive data and count in rapid S108 description, reception device to transmit, when the device for needing to receive corresponding data connects
Receive the data number of blocks after cutting in step S102（This example is 15）Data block after, data block is connected according to original order
Get up, and behind remove in last data block that afterbody is unnecessary 0, that is, complete DRP data reception process.
It is consistent as described in step S109.After data receiver is finished, according to step S110 requirement, it is necessary to receive corresponding data
Device device of the stop signal to the data for storing transmission in need is sent on two data links.Storage transmission in need
The devices of data receive and stop sending packet after stop signal in step S110, and cut off corresponding transmission data
Link.As step S111 descriptions are consistent.
In whole transmitting procedure, both links coordinate automatically, and the property caused by link-speeds are inconsistent can be made up automatically
The loss of energy, is maximized efficiency of transmission.
