Referring to Fig.1, Fig. 1 is a kind of schematic diagram of the data transmission system 99 based on TCP provided in an embodiment of the present invention.Number
According to Transmission system 99 for running the data transmission method based on TCP.Data transmission system 99 includes source device 100 and target
Equipment 200.In the present embodiment, source device 100 is client.Target device 200 is server.Source device 100 is set to target
The data of standby 200 transmission can be but be not limited to real-time audio and video data.
Fig. 2 is the flow diagram of the data transmission method based on TCP run in source device 100.Data transmission
Method is executed by source device 100 and transfers data to target device 200 to realize.Wherein, source device 100 transmits data to target
Before equipment 20, source device 100, which with target device 200 is completed three-way handshake and establishes, to be connect.That is, the data transmission method is
Based on what is executed on the basis of source device 100 and the well-established connection of target device 200.Source device 100 and target device 200
How completing three-way handshake can carry out according to existing TCP transmission agreement, and details are not described herein.Under the data transmission method includes
Face step.
Data to be transmitted is divided into the multiple source datas packet of preset order by step S201.Specifically, source device 100 will
It needs to be sent to the data to be transmitted of target device 200 and according to the size of setting is divided into multiple source datas packet and to each source
One serial number of data packet, serial number user indicate the transmission sequence of each data packet.In the present embodiment, the size of each source data packet
It is identical, that is, the size of each source data packet is fixed.For example, the size of each source data packet is fixed as 2bit.
Each source data packet progress redundancy encoding is formed multiple coded data packets by step S203.Specifically, source device
Each source data packet is carried out redundancy encoding by 100.Wherein, source device 100 uses the information code more than the information content than source data packet
Source data packet is encoded, coded data packet is formed.It is to be appreciated that twice of the size of coded data packet than source data packet
Size it is also big.For example, the size of source data packet is 2bit, then coded data packet is greater than 4bit, for example, 5bit or more
Greatly.In the present embodiment, the information number of codes used when source device 100 carries out redundancy encoding to source data packet is identical, that is, each to compile
The size of code data packet is identical.Coded data packet also has a serial number, identical as the serial number of corresponding source data packet data.
Step S205 sends coded data packet to target device according to the preset order.Specifically, source device 100 according to
The serial number of each source data packet sends coded data packet to target device 200, ensures that coded data packet and source data packet
Serial number it is consistent.
Step S207, if currently transmitted coded data packet does not receive target device really within a preset time after sending
When recognizing information, judge that currently transmitted coded data packet has been lost.Specifically, one coded data of the every transmission of source device 100
Packet, will start timer just to wait target device 200 to receive currently transmitted coded data packet.When target device 200 receives
When to the coded data packet, the confirmation message for indicating to have received currently transmitted data packet is sent to source device 100.When source is set
Standby 100 do not receive the confirmation message within the preset time, then judge that currently transmitted coded data packet has been lost.
Step S209 sends next coding when the coded data packet lost is not the last one coded data packet
Data packet is to target device.Specifically, if the coded data packet lost is not the last one coded data packet, source device
100 send next data packet to target device 200.If the coded data packet lost is the last one data packet, stop
It sends.For example, there is packet loss when being sent to third coded data packet, then source device when coded data packet is altogether by N number of
100 continue to send the 4th coded data packet, and so on, until all coded data packets are sent.
In above-described embodiment, if currently transmitted coded data packet loss, source device 100 directly transmit next coded number
According to packet to target device 200, without retransmitting, cause subsequent transmission to the data of target device 200 so as to avoid retransmitting
Failure, and transmission speed can be promoted.In above-described embodiment, since coded data packet is using redundancy encoding, a coding
Data-bag lost only loses fraction source data, and when decoding still can be reduced to initial data.
Fig. 3 is please referred to, runs on one of target device 200 based on TCP's for what one embodiment of the invention provided
The flow chart of data transmission method.The data transmission method includes below step.
Step S301 receives the coded data packet that source device is sent according to preset order.Specifically, in the coded data packet
The source data packet that need to be sent to target device 200 including source device 100.The coded data packet is source device 100 to source data packet
Carry out redundancy encoding formation.Source data packet is that the data to be transmitted that 100 pairs of need of source device are transferred to target device 200 is divided
It cuts.
Step S303 judges when not receiving the currently transmitted coded data packet of source device within the preset time
The currently transmitted coded data packet of source device has been lost.Specifically, the currently transmitted coded data packet of source device is that target is set
Standby 200 currently need received coded data packet, if target device 200 does not receive within a preset time, judge that source is set
Standby 100 currently transmitted coded data packets have been lost.
Step S305, it is next into receiving when the coded data packet lost is not the last one coded data packet
The reception state of coded data packet.Specifically, when the coded data packet lost is not the last one data packet, target device
200 are directly entered the state for receiving next coded data packet, and source device 100 can be made to be sent to the number of target device 200
It can be received by target device 200 according to packet.
Step S307 obtains next data packet that source device is sent.
Step S309, if the coded data packet received is the last one coded data packet, all volumes for will receiving
Code data packet is decoded.Specifically, target device 200 can will be compiled to when receiving all coded data packets and being decoded
Code data packet is reduced to source data packet.Since coded data packet is using redundancy encoding, even if one of data or a small amount of
The coded data packet received is decoded the source data packet that still can include by the coded data packet of loss by data-bag lost
It decodes and.
Decoded data packet is packaged together according to preset order and is sent to application layer by step S311.
Step S313, when the coded data packet lost is the last one coded data packet, all volumes for will receiving
Code data packet is decoded, and executes step S311.

S406, when receiving coded data packet N1, the transmission of target device 200 confirmation message R1To source device 100.
S407, when receiving confirmation message R1, the transmission of source device 100 coded data packet N2To target device 200.
S408, when not receiving coded data packet N within a preset time2, target device 200 judges coded data packet N2
It has been lost that, and enter and receive coded data packet N3State, without sending confirmation message R2To source device.
S409, when not receiving confirmation message R within a preset time2, source device 100 judges coded data packet N2It has lost
It loses, directly transmits coded data packet N3。
It is to be appreciated that source device 100 continues to send coded data packet N according to above method4~N6, target device 200 presses
Coded data packet N is continued to according to above method3~N6, details are not described herein.In the present embodiment, N3~N6All set by target
Standby 200 receive successfully.
S410, when target device 300 receives the last one data packet R6When, target device 200 is to the coding received
Data packet N1,N3~N6It is decoded, available source coded data packet D1~D6。
Decoded data packet is packaged together according to preset order and is sent to application layer by S412.
In above-described embodiment, coded data packet N2It loses, source device 100 is without retransmitting coded data packet N2, and after supervention
Send coded data packet N3.Target device 200 can directly receive coded data packet N3, without waiting for reception coded data packet N2.Cause
This, can be to avoid N3~N6By coded data packet N2Losing influences and Problem of Failure.In addition, since source data packet carries out redundancy volume
Code, even if the source data packet lost can also be gone out by decoded back by being lost code segment data packet.
