Embodiment Construction

[0044] In order to make the purpose, technical methods and advantages of the embodiments of the present invention clearer, the technical methods of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] Currently, network coding techniques can be mainly divided into two categories: inter-stream network coding and intra-stream network coding. The network coding technology mainly involved in the embodiments of the present invention is in-stream network coding, and the following network coding specifically refers to the in-stream network coding technology.

Abstract

The invention provides a hybrid transmission method based on linear network coding, electronic equipment and a storage medium, and relates to the technical field of network coding, including obtaining n original data packets in the current group, and sending the n original data packets to a receiving end; When the n original data packets are sent, then m coded data packets calculated during the sending process are sent to the receiving end, where m≤n; when x out of the n original data packets are lost, the receiving end Set the encoding coefficient matrix, the received encoded data packet and the original data packet, and restore x lost data packets, where x<m, so that the reliability of data transmission can be enhanced as a whole, and at the same time the mixed transmission of encoded data and original data The feature can greatly reduce the encoding and decoding operation time, and the preset encoding coefficient matrix can reduce the decoding failure rate and reduce the transmission load.

Description

technical field [0001] The invention relates to the technical field of network coding, in particular to a hybrid transmission method based on linear network coding, electronic equipment and storage media. Background technique [0002] Network coding technology is a new technology produced by the combination of information theory and network transmission engineering practice. The network coding technology implements some kind of encoding on the transmission information on the transmission node, so as to realize the high throughput rate and reliable transmission of the link. [0003] In existing network coding transmission applications, the purpose of restoring the original data packet is often achieved by using random coding coefficients and then transmitting the coded data packet, but the above method has a high decoding failure rate and a long delay. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a hybrid transmissi...
