Upper described, technical solution provided in an embodiment of the present invention can reduce network overhead.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to the accompanying drawing to this
The specific embodiment of invention is described in detail.
Referring to Fig. 1, the embodiment of the invention provides a kind of transmission methods of data, may include steps of:
Step S101 obtains data packet to be transmitted.
In specific implementation, the data packet to be transmitted can be one, or multiple.
In specific implementation, when mistake occurs in transmission process when data or losing, due to existing technical solution
Network overhead is larger, therefore consideration of the embodiment of the present invention carries out joint verification to data packet to be transmitted, obtains check code, then base
The data packet of data packet or loss that mistake occurs is corrected in the check code.
In specific implementation, the data packet to be transmitted can be user packet protocol (User
DatagramProtocol, UDP) data packet, or Internet of Things (Internet of things, IOT) data packet may be used also
Think other protocol data packets, belongs to the protection scope of the embodiment of the present invention.
In an embodiment of the present invention, the data packet to be transmitted is following at least one: IOT data packet, UDP message
Packet.
Step S102 generates school identical with the data packet size to be transmitted for the data packet to be transmitted
Code is tested, and the i-th bit in the check code is by being verified to the i-th bit in the data packet to be transmitted 0
≤ i≤N-1, N are the digit of the data packet to be transmitted.
In specific implementation, when mistake occurs in transmission process when data or losing, due to existing technical solution
Network overhead is larger, therefore the embodiment of the present invention combine to the i-th bit in the data packet to be transmitted and be verified
Code is then based on the check code and corrects the data packet that mistake occurs or loses.
In specific implementation, when the data packet to be transmitted is multiple, the digit of multiple data packets to be transmitted can
, can not also be identical with identical, N is the digit of a data packet to be transmitted in multiple data packets to be transmitted.
In specific implementation, when the data packet to be transmitted is multiple, the i-th bit in the check code is by right
I-th bit in the data packet to be transmitted carries out what joint verification obtained.
For example, data packet to be transmitted includes: P1, P2 and P3, wherein the digit of P1 is N1, and the digit of P2 is N2, P3's
Digit is N3, and N2 < N1 < N3 then has:
Joint verification is carried out to the 1st of P1, P2, P3, the check value of generation is as the 1st bit check code；
Joint verification is carried out to the 2nd of P1, P2, P3, the check value of generation is as the 2nd bit check code；
…
Joint verification is carried out to N2 of P1, P2, P3, the check value of generation is as N2 bit check code；
Joint verification is carried out to N2+1 of P1, P3, the check value of generation is as N2+1 bit check code；
…
Joint verification is carried out to N1 of P1, P3, the check value of generation is as N1 bit check code.
In specific implementation, the check code can be odd check code, or even parity check code can also be circulation school
Code is tested, the protection scope of the embodiment of the present invention is belonged to.
In an embodiment of the present invention, using following at least one algorithm to the i-th of all data packets to be transmitted
Position is verified: odd, even parity check, cyclic check.
In specific implementation, the check code can be one, or multiple (two or more).
Using multiple check codes, the information of more data to be transmitted packets can be obtained, is entangled to improve based on check code
The success rate of the data packet of the positive data packet that mistake occurs or loss, further increases the robustness of data transmission.
In specific implementation, when the check code is multiple, multiple check codes can use identical checking algorithm,
Different checking algorithms can be used.
For example, carrying out joint verification using odd algorithm to all data packets to be transmitted, generating check code 1；
Using even parity check algorithm, joint verification is carried out to all data packets to be transmitted, generates check code 2.
Multiple and different check codes is generated using different checking algorithms, be can be further improved to correct based on check code and be sent out
The success rate of the data packet of the data packet or loss of raw mistake, the robustness of improve data transfer.
It is understood that check code provided in an embodiment of the present invention, substantially and a kind of FEC.
Step S103 sends the check code of the data packet to be transmitted and generation.
In specific implementation, the check code of the data packet to be transmitted and generation can be sent simultaneously, so that
Receiving end can correct the data packet or loss that mistake occurs based on the check code and the data packet being properly received
Data packet, so that transmitting terminal be avoided to retransmit the data packet that wrong data packet or loss occurs.
For receiving end, when the data packet number being properly received is more, and the data packet that mistake occurs or loses
When number is less, the data packet of data packet or loss that mistake occurs can be corrected based on check code, to avoid transmitting terminal
Retransmit the data packet of data packet or loss that mistake occurs.
For example, receiving end received correctly 9 data packets, only 1 data packet malfunctions, then can be according to check code
Restore that wrong data packet occurs by turn.
Check code identical with data packet size to be transmitted is generated for data packet to be transmitted using above scheme,
Then data packet to be transmitted and its corresponding check code are sent.Since check code is by every in data packet to be transmitted
One is verified and is obtained, therefore one side digit is less, and identical as the digit of data packet to be transmitted, network overhead is small；Separately
On the one hand receiving end can be made to correct the data packet of data packet or loss that mistake occurs based on check code, to avoid sending out
Sending end retransmits the data packet of data packet or loss that mistake occurs, reduces network overhead, the robustness of improve data transfer.It is comprehensive
