Problems solved by technology

At present, in order to increase the transmission distance of point-to-point data transmission between communication terminals, it is usually necessary to reduce the data transmission rate
However, directly changing the data transmission rate of point-to-point data transmission between communication terminals requires multiple digital signal processing for transmission data of multiple different data transmission rates, which increases the cost and time of data transmission in Ethernet

Abstract

The invention provides a data transmission method and a system in Ethernet, computer equipment and a medium. The method comprises the following steps: comparing a transmission distance between a first communication terminal and a second communication terminal with at least one preset threshold value, and determining the number of repeated sending times of a target data packet at the first communication terminal according to a comparison result; and repeatedly sending the target data packet at the first communication terminal to enable the second communication terminal to receive the plurality of data packets, and processing the plurality of data packets through an error correction algorithm to obtain the target data packet. The data transmission method provided by the embodiment of the invention reduces the cost and time of data transmission in the Ethernet.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a data transmission method, system, computer equipment and medium in Ethernet. Background technique [0002] In the Ethernet communication system, data transmission is performed between communication terminals through the physical layer. The transmission distance of point-to-point data transmission between communication terminals is related to the transmission frequency of the data carrier signal. The higher the frequency, the greater the channel attenuation, the more serious the intersymbol interference, and the shorter the transmission distance. Taking the 802.3ab Ethernet standard formulated by IEEE as an example, when transmitting data at a transmission rate of 1Gbps on four pairs of Category 5 twisted pair lines, the limit transmission distance of data is about 160 meters. However, in the actual application of Ethernet, it is often necessary t...
