NETWORK ENCODING AND TRANSMISSION METHOD BASED ON UDP PROTOCOL

The present invention relates to a network encoding and transmission method based on the UDP protocol, comprising the following steps: establishing a network encoding layer that is connected to a transmission layer by using the UDP protocol, wherein data or a file enters from an application layer of a transmit end to a network encoding layer of the transmit end, and is processed in the network encoding layer of the transmit end to form network code, a data packet with a number is generated in a set manner by using the network code, and the data packet is sent to a receive end by the transmission layer of the transmit end; a network encoding layer of the receive end receiving the encoded data packet by a transmission layer of the receive end, identifying the number of the received data packet, returning a different response signal to the transmit end according to the received number, decoding the data packet to obtain data or a file, and transmitting the data or the file to an application layer of the receive
