Description
Technical field
The present invention relates to technical field of data transmission more particularly to a kind of data transmission methods.
Background technology
Traditional TCP-IP agreements be not only used as transmitting message sequence the byte count of transmission but also as transmittings
Confirmation mark, this method relies on the accumulative confirmation of multiple DACK or ACK overtime timers come trigger data repeating transmission, while client
End faces extremely complex network environment in the process carried out data transmission with server, as data are easily touched in network transmission
To network congestion and the influence of packet loss, it is particularly likely to encounter in remote transmission, this leads to the number of client and server
According to transmission speed it is slow, be not sufficiently stable, real-time is poor, success rate is not high.
Therefore, the prior art is defective, needs to improve.
Invention content
The technical problem to be solved by the present invention is to：A kind of data transmission method is provided, promotes the number of client and server
According to transmission speed, stability, success rate.
Technical scheme is as follows：A kind of data transmission method is provided, is included the following steps：
S1：The data for needing to send are divided into data packet by a certain fixed word joint number and numbered by data sending terminal, and by volume
Number sequence sends several data packets to data receiver, to package number, it is convenient to each data packet into line trace.
S2：Data receiver is received with numbered data packet, and to the total data that data sending terminal transmits and receives
The number of packet, the data packet that data receiver has received to data sending terminal feedback.
S3：Data sending terminal receives the number of data packet that data receiver is sent, and the package number that will be received
Compared with the package number sent, judge data transmission procedure whether lost data packets.
S4：When data sending terminal judges the non-lost data packets of data transmission procedure, data sending terminal continues suitable according to numbering
Sequence sends subsequent several data packets to data receiver；When data sending terminal judges data transmission procedure lost data packets, number
The data packet of loss and subsequent several continuation are sent to data receiver according to the data packet of number order according to transmitting terminal.
S5：The numbered data packet of band that data sending terminal is sent in data receiver receiving step S4, and sent out to data
The number for the entire packet that sending end transmits and receives.
S6：After data sending terminal receives the total data packet number of data receiver transmission, data sending terminal terminates
Data are sent.
Further, the data transmission method in step S6, further includes：When data sending terminal receives data receiver
During the package number that the package number sent is held to be not all of, data sending terminal repeats step S4 and step S5.
Further, the fixed word joint number is 1024 bytes.
Further, the data are encrypted before step S1, avoid being stolen by data.
Further, the data sending terminal is client or server, the data receiver also for client or
Person's server；When transmitting file is to server in client, client is data sending terminal, and server is data receiver；When
Client from server download file when, the server be data sending terminal, the client be receiving terminal.
Using the above scheme, the present invention provides a kind of data transmission method, and data are pressed a certain byte number by data sending terminal
It is divided into data packet and numbers, then data receiver is delivered a packet to by the number order of data packet, data receiver will connects
The package number received feeds back to data sending terminal, and the package number that data sending terminal is fed back according to data receiver is sentenced
Disconnected packet drop and the data re-transmitting to packet loss, and accumulative confirmation or ACK overtime timers without relying on multiple DACK come
Trigger data is retransmitted, and greatly promotes data transmission bauds, stability, real-time and success rate.
Description of the drawings
Fig. 1 is the flow chart of the present invention；
Fig. 2 is a kind of application scenario diagram of the present invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Referring to Fig. 1, the present invention provides a kind of data transmission method, include the following steps：
S1：The data for needing to send are divided into data packet by a certain fixed word joint number and numbered by data sending terminal, and by volume
Number sequence sends several data packets to data receiver, to package number, it is convenient to each data packet into line trace.
S2：Data receiver is received with numbered data packet, and to the total data that data sending terminal transmits and receives
The number of packet, the data packet that data receiver has received to data sending terminal feedback.
S3：Data sending terminal receives the number of data packet that data receiver is sent, and the package number that will be received
Compared with the package number sent, judge data transmission procedure whether lost data packets.
S4：When data sending terminal judges the non-lost data packets of data transmission procedure, data sending terminal continues suitable according to numbering
Sequence sends subsequent several data packets to data receiver；When data sending terminal judges data transmission procedure lost data packets, number
The data packet of loss and subsequent several continuation are sent to data receiver according to the data packet of number order according to transmitting terminal.
S5：The numbered data packet of band that data sending terminal is sent in data receiver receiving step S4, and sent out to data
The number for the entire packet that sending end transmits and receives.
S6：After data sending terminal receives the total data packet number of data receiver transmission, data sending terminal terminates
Data are sent.
The data transmission method in step S6, further includes：When data sending terminal receives the number that data receiver sends
During the package number being not all of according to packet number, step S4 and step S5 is repeated.
The fixed word joint number is 1024 bytes.
The data are encrypted before step S1, avoid being stolen by data.
Referring to Fig. 2, the data sending terminal is client 10 or server 20, the data receiver is also client
End 10 or server 20；When transmitting file is to server 20 in client 10, client 10 be data sending terminal, server 20
For data receiver；When client 10 from server 20 download file when, the server 20 be data sending terminal, the client
End 10 is data receiver.
Referring to Fig. 2, when user needs the file being locally stored in disk 30 being transmitted to cloud disk, client 10 is then number
According to transmitting terminal, server 20 is data receiver, and data are divided into data packet and numbered by client 10, are then sent to server
20, the number of data packet that then 20 feedback reception of server arrives is to client 10；When user downloads the file into this from cloud disk 40
During ground storage dish 30, server 20 is data sending terminal, and client 10 is data receiver, and data are divided into data by server 20
It wraps and numbers, be then sent to client 10, the number of data packet that then 10 feedback reception of client arrives is to server 20.
In conclusion the present invention provides a kind of data transmission method, data are divided by data sending terminal by a certain byte number
Data packet is simultaneously numbered, then delivers a packet to data receiver by the number order of data packet, and data receiver will receive
Package number feed back to data sending terminal, the package number that data sending terminal is fed back according to data receiver judges to lose
Packet situation and the data re-transmitting to packet loss, and triggered without relying on accumulative confirmation or the ACK overtime timers of multiple DACK
Data re-transmitting greatly promotes data transmission bauds, stability, real-time and success rate.
The foregoing is merely a prefered embodiment of the invention, is not intended to restrict the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should all be included in the protection scope of the present invention.
