A method for load balancing and packet re-sequencing on a network includes an ingress node that determines an identifier of a destination chip based on a destination address of a packet flow and a forwarding table, allocates, based on the identifier of the destination chip, a channel identifier and a sequence number of each packet that is in the packet flow and that enters a channel, to generate an updated packet flow, where each packet in the updated packet flow includes a packet in a corresponding packet flow, a sequence number of the packet, and the channel identifier, and the updated packet flow is sent in a per-packet load sharing manner.

Method and apparatus for load balancing and packet re-sequencing on network

A memory management method includes: determining that available storage space of a first memory in a network device is less than a first threshold, where the first threshold is greater than 0 and the first memory stores a first packet queue; and deleting at least one packet at the tail of the first packet queue from the first memory based on the available storage space of the first memory being less than the first threshold. When the available storage space of the first memory is less than the first threshold, a packet queue, namely, the first packet queue, is selected and a packet at the tail of the packet queue is deleted from the first memory.

Buffer management method and apparatus

A method for determining a packet dequeue rate includes allocating a plurality of consecutive blocks in a first memory to a first packet, storing the first packet and a first length in the plurality of blocks, where the first length is of a first packet queue and is obtained when the first packet is enqueued into the first packet queue, and determining, based on a first span and the first length stored, a first rate at which a packet in the first packet queue is dequeued, where the first span is equal to a difference between a second time and a first time, the first time is when the first packet is enqueued into the first packet queue, and the second time is when the first packet is dequeued from the first packet queue.
