Abstract

The invention discloses a data transmission method, a transmitting end, a receiving end and a data transmission system and belongs to the communication technical field. The data transmission method includes the following steps that: data to be transmitted are segmented divided into a plurality of data packets according to a preset data unit, and the data packets are numbered consecutively, and the size of the preset data unit is smaller than a largest transmission unit; the transmitting end transmits the data packets to the receiving end sequentially; the receiving end receives the data packets transmitted by the transmitting end and judges whether packet loss occurs according to the continuity of the serial numbers of the received data packets, and feeds back packet loss information to the transmitting end according to a preset period; and the transmitting end retransmits lost data packets to the receiving end according to the packet loss information until the receiving end successfully receives all the data packets or the transmitting time of the data packets reaches preset time. The data transmission method, transmitting end, receiving end and data transmission system of the invention have the advantages of high data transmission speed and high reliability.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a data transmission method, a sending end, a receiving end and a data transmission system. Background technique [0002] With the accumulation of social wealth and the acceleration of the pace of life, people have put forward higher requirements for high-quality and fast quality of life. Beautiful music and good-looking videos have become an indispensable part of life, and data such as these audio and video files often need to be transmitted between smart speakers. [0003] In the prior art, data transmission mainly adopts the following two methods: [0004] Method 1: Data transmission is performed based on TCP (Transmission Control Protocol, transmission control protocol). Although this data transmission method has high transmission reliability, its disadvantage is that the transmission speed is relatively slow. [0005] Method 2: Data transmission is ba...
