Data transmission method, data transmission apparatus and data transmission device based on Ethernet udp protocol, and medium

Abstract

The embodiment of the invention discloses a data transmission method, a data transmission apparatus and a data transmission device based on an Ethernet udp protocol, and a computer readable storage medium. The method comprises the following steps: a sending end sends a file information packet containing to-be-transmitted data size through a udp protocol format, divides the to-be-transmitted data into a plurality of grouped data packets according to a value of the number of sequences and the sequence size fed back by a receiving end, divides one grouped data packet into a plurality of sequencepackets and sends the sequence packets, and sends a grouped ending packet after completing sending of each grouped data packet; in a transmission process of one grouped data packet, when the receivingend confirms that an unreceived sequence packet exists according to a sequence number of each sequence packet, the receiving end sends a retransmission request containing packet loss information, andthe sending end retransmits the corresponding sequence packet according to the packet loss sequence number in the retransmission request. The method, the apparatus, the device and the medium providedby the invention realize that the Ethernet udp protocol lose data under a congested network environment no longer, meanwhile, can transmit large-capacity, real-time and reliable data under the non-congested environment.

Description

technical field [0001] Embodiments of the present invention relate to the field of Ethernet technologies, and in particular, to a data transmission method, apparatus, device, and computer-readable storage medium based on the Ethernet udp protocol. Background technique [0002] With the rapid development of network technology, more and more large-capacity data needs to be transmitted through the network. Ethernet is the most common communication protocol standard used in today's existing local area networks. It uses CSMA / CD (Carrier Sense Multiple Access and Collision Detection) technology and runs on various types of cables at a rate of 10M / S. [0003] In Ethernet-based data transmission, data transmission can be performed through the Ethernet tcp ((Transmission Control Protocol, Transmission Control Protocol)) protocol, but this transmission method is relatively inefficient and is not suitable for real-time, large-capacity data transmission. The Ethernet udp (User Datagram...

Problems solved by technology

[0004] However, the Ethernet udp protocol cannot guarantee reliable data transmission. When the network is congested, the possibility of data loss is extremely high. It is not suitable for data transmission scenarios with high requirements for real-time performance, large capacity and reliability.
