Abstract
A packet forwarding method includes a first network device receiving a first message from a second network device via a second egress port of the second network device, where the first message measures a phase difference, and where the phase difference is a phase difference between a switching time of one of a plurality of first buffers of a first egress port of the first network device and a switching time of one of a plurality of second buffers of the second egress port of the second network device with a link delay taken into consideration. The first network device determines the phase difference based on the first message. Then, the first network device schedules, based on the phase difference, a second data packet sent via the first egress port.
