The invention discloses a data communication method, device and system and a storage medium, and relates to the technical field of Ethernet communication, and the data communication method comprises the steps: firstly obtaining a plurality of data packets generated by an upper-layer application, and then constructing corresponding communication sub-packets according to the data length, the content and the check code of the data packets; and extracting a standard Ethernet frame header, inserting a combined identification field, splicing the communication sub-packets to the identification field in sequence, adding a frame verification sequence to generate a combined packet, and sending the combined packet to a receiving end. And the receiving end executes first integrity check through the frame check sequence, splits the communication sub-packets according to the merging identifier after the first integrity check passes, and executes second integrity check through the communication sub-packet check code to process the effective communication sub-packets. According to the invention, the redundancy overhead is reduced through merging and packaging of multiple small data packets, the equipment compatibility is guaranteed by the standard frame header, the anti-error-code capability is improved through double-layer verification, and the transmission efficiency and the anti-error-code performance of the small data packets can be optimized while the compatibility is considered.
