Data transmission method and system, computer equipment and medium

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. 本发明提供了一种以太网中的数据传输方法、系统、计算机设备和介质。该方法包括：将第一通信终端和第二通信终端之间的传输距离与至少一个预设阈值进行比较，根据比较结果确定目标数据包在第一通信终端的重复发送次数；在第一通信终端重复发送目标数据包，以使第二通信终端接收多个数据包，并将所述多个数据包通过纠错算法处理，以
