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.

Abstract: An information sharing method includes that a first redundancy device generates a first supervision frame that includes device information of the first redundancy device, where the first supervision frame detects whether a second redundancy device on a transmission link on which the first redundancy device is located in the redundancy network is in a working state, where the first redundancy device is any redundancy device in the redundancy network; and where the first redundancy device sends the first supervision frame to the second redundancy device in a multicast manner. The device information of the redundancy device is carried in the supervision frame.

Abstract: A power management method includes power sourcing equipment (PSE) supplying power to a plurality of powered devices (PDs), and determining reserved power of the PSE based on a power usage status, where the reserved power is used to continue supplying power to the plurality of PDs when actual available power of the PSE is exhausted, and where the reserved power varies with the power usage status of the PSE.
