Abstract: A queue management method and apparatus are disclosed. The queue management method includes: storing a first packet to a first buffer cell included in a first macrocell, where the first macrocell is enqueued to a first entity queue, the first macrocell includes N consecutive buffer cells, and the first buffer cell belongs to the N buffer cells; correcting, based on a packet length of the first packet, an average packet length in the first macrocell that is obtained before the first packet is stored, to obtain a current average packet length in the first macrocell; and generating, based on the first macrocell and the first entity queue, queue information corresponding to the first macrocell of the first macrocell in the first entity queue, a head pointer in the first macrocell, a tail pointer in the first macrocell, and the current average packet length in the first macrocell.

Abstract: This application discloses a method for forwarding a packet in a data center network. A first device obtains an original packet, and adds a first source label to the original packet to obtain a first packet. The first source label includes a forwarding type, an indication field, and an interface sequence. The forwarding type indicates that the first packet supports source label forwarding, the interface sequence indicates a first source label forwarding path of the original packet, and the indication field indicates information that is about an outbound interface and that should be read from the interface sequence. The first device sends the first packet to a next-hop switch through the outbound interface corresponding to the first source label forwarding path. The next-hop switch receives the first packet, and forwards the first packet based on the first source label.
