Abstract: Embodiments of the present invention provide a packet processing method and apparatus. After receiving a packet, a first network device processes the packet, and determines a first latency of the processed packet in a FIFO memory, where: the first latency is equal to a difference obtained by subtracting a second latency from a target latency, the second latency includes a third latency, and the third latency includes a time interval for processing the packet.

Abstract: A time synchronization method and a device, where the method includes generating, by a first device, a first time synchronization frame according to a first coding scheme, where the first time synchronization frame includes a first frame header and a first time of day (TOD), the first frame header carries an identifier of the first coding scheme, and the first coding scheme defines a boundary of the first time synchronization frame and a location of the first TOD in the first time synchronization frame, and sending, by the first device, the first time synchronization frame to a second device using a first single line to trigger the second device to identify the first time synchronization frame according to the identifier of the first coding scheme, to obtain the first TOD from the first time synchronization frame, and to trace a time of the first device according to the first TOD.
