Abstract
In a data transmission method, if a to-be-transmitted second data frame exists in a process in which a network device transmits a first data frame, and a priority of the second data frame is higher than a priority of the first data frame, the network device determines a frame type of the second data frame as an express frame. The network device adjusts a frame type of the first data frame to a preemptable frame if the frame type of the first data frame is an express frame. Then, the network device stops transmitting the first data frame, and starts to transmit the second data frame.

A method comprising:
- determining, in response to a second data frame existing in a process of transmitting a first data frame and in response to a second priority of the second data frame being higher than a first priority of the first data frame, a second frame type of the second data frame as an express frame type, wherein the first data frame comprises a start m delimiter (SMD) field, and wherein the SMD field comprises a value;
- determining a first frame type of the first data frame based on the value;
- adjusting, in response to the first frame type being the express frame type, the first frame type to a preemptable frame type by adjusting a first frame type mark of the first data frame to a second preemptable frame mark;
- stopping transmission of the first data frame;
- and
- starting transmission of the second data frame.
