A data transmission method, apparatus, chip, medium, and product

Abstract

This application provides a data transmission method, apparatus, chip, medium, and product, relating to the field of data transmission technology. The method includes: acquiring a target protocol data unit; acquiring the superframe number corresponding to the target protocol data unit and determining the superframe number corresponding to the target protocol data unit as a first target superframe number; acquiring a second target superframe number corresponding to a protocol data unit to be transmitted; calculating the absolute value of the difference between the first target superframe number and the second target superframe number; and controlling the transmitting end to stop transmitting the protocol data unit to be transmitted to any of the multiple transmission paths when the absolute value of the difference between the first target superframe number and the second target superframe number is detected to be greater than a first preset value. By limiting the absolute value of the difference between the first target superframe number and the second target superframe number, the HFN out-of-sync problem between the transmitting and receiving ends can be actively avoided, ensuring the smoothness and correctness of data transmission and reception, and has advantages such as low cost, high efficiency, and simple implementation.
