Abstract: This application provides a packet scheduling method and a related device. The method includes: An access device receives a to-be-scheduled packet, and obtains an actual packet length of the to-be-scheduled packet; the access device determines a first compensation value and a second compensation value based on the to-be-scheduled packet, and determines a first packet length and a second packet length; and the access device schedules the to-be-scheduled packet based on the first packet length and the second packet length. By implementing the method in this application, the access device estimates a packet length of a packet received by each device on a packet forwarding path, and then schedules the packet based on the estimated packet length of the packet received by each device, so that the access device can manage bandwidth of each device on a network more accurately.
