Abstract: This application provides a data transmission method and a network device. The method includes: sending, by a first network device, request information to a second network device; receiving, by the first network device, grant information sent by the second network device, where the grant information includes a first sequence number; determining, by the first network device, a first credit limit based on the first sequence number, where the first credit limit is an amount of data that is allowed to be sent by the first network device in a packet-distributed load sharing manner; and sending, by the first network device, data to the second network device based on the first credit limit.

Abstract: This application provides a link management method. The physical device includes a first memory that stores a tail pointer of a link and a second memory that stores a head pointer of the link, and the physical device supports one time of enqueue processing and one time of dequeue processing in one clock cycle. The method includes: when a first link is not empty before the enqueue processing, modifying, by the physical device, a first tail pointer that is of the first link and that is in the first memory; and when a second link is not empty after the dequeue processing, modifying, by the physical device, a second head pointer that is of the second link and that is in the second memory.
