Problems solved by technology

[0005] In the above prior art, the redundancy of encoding depends on N. If the redundancy is to be low, N needs to be large, and to restore a data packet needs to wait for N data packets, resulting in a long delay
And because FEC encodes only one redundant packet in one row or column, at most one data packet is lost in the same row or column, which cannot resist continuous packet loss
In addition, even if the N*M model can resist continuous packet loss through iterative recovery, it may require N*M recovery delays. Therefore, the data packet transmission method provided by the prior art has a long delay in recovering lost packets, and the recovery ability Difference

Embodiment 1

[0036] Since the network environment is different at different times, during the transmission of data packets through the network, if the network environment is poor at this time, data packet loss may occur, resulting in missing data packets received by the receiving end. , resulting in low reliability of transmitted data packets.

[0037] In order to prevent the above situation, the embodiment of the present invention provides a data packet transmission method, which can be applied to devices that need to perform network transmission, including but not limited to terminals, servers, etc. limited. see figure 1 , taking the sender of the data packet as the execution subject as an example, the method flow provided by this embodiment includes:

[0038] 101: Obtain at least one data packet to be sent, and obtain RS code redundancy;

[0039] Among them, the RS code redundancy is obtained, including but not limited to:

[0040] Receive the redundancy confirmation information sen...

Embodiment 2

[0049] An embodiment of the present invention provides a data packet transmission method. Combining with the content of the first embodiment above, this embodiment takes the execution subject as a receiving end as an example to illustrate the method provided by this embodiment. see figure 2 , the method flow provided by this embodiment includes:

[0050] 201: Receive at least one encoded data packet sent by the sender;

[0051] Wherein, it can be seen from the process of sending data packets by the sending end in the first embodiment above, after the encoded data packets are determined by the sending end according to the acquired RS code redundancy The number of and the determined number of redundant packets are obtained by encoding the data packets to be sent according to the RS algorithm.

[0052] Optionally, in order to enable the sending end to encode the data packet to be sent according to the specific packet loss situation, in the method provided by this embodiment, b...

Embodiment 3

[0058] An embodiment of the present invention provides a method for transmitting a data packet, and the method provided in this embodiment is described with an example in combination with the contents of the first and second embodiments above. see image 3 , the method flow provided by this embodiment includes:

[0059] 301: The sender acquires at least one data packet to be sent;

[0060] Specifically, this embodiment does not specifically limit the method of obtaining at least one data packet to be sent, including but not limited to, the sending end organizes the data in the data packet according to its own business logic, and at the same time determines the number of data packets to be sent according to the actual situation. number, so as to determine the data packet to be sent, and use the determined data packet to be sent as the acquired data packet.

[0061] Further, the data packets to be sent obtained by the sending end in this step are the data packets to be sent th...

Abstract

The invention discloses a data packet transmission method and a device, and belongs to the technical field of an internet. The method comprises that: at least one data packet to be sent is acquired, and RS code redundancy is acquired; number of redundant packets is confirmed according to the acquired RS code redundancy; the data packets to be sent are encoded on the basis of an RS algorithm according to the number of the redundant packets and the number of the data packets to be sent so that the encoded data packets are obtained; and the encoded data packets are sent to a receiving terminal. The number of the redundant packets can be confirmed according to the acquired RS code redundancy. After the data packets to be sent are encoded on the basis of the RS algorithm according to the number of the redundant packets and the number of the data packets to be sent, the obtained encoded data packets are sent to the receiving terminal so that packet loss data can be recovered according to any data packets in the received data packets sent by a sending terminal when packet loss occurs. Therefore, delay in recovery of the lost packets is short, recovery capability is high and data packet transmission is relatively high in reliability.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data packet transmission method and device. Background technique [0002] With the popularization of the Internet, there are more and more data packets in the network. In different network application services, the transmission quality of the data packets directly affects the user's use experience of the network application. Wherein, during the transmission of the data packet, the packet loss of the data packet seriously affects the transmission quality of the data packet. For example, when video data packets are being transmitted, if the video data packets are lost during the transmission process, the video picture may be blurred or paused, which seriously affects the user's video viewing effect. Therefore, in order to solve the above problems, it is generally necessary to adopt a certain data packet transmission method to make the data packet more reliable during transm...
