摘要： A congestion control method and apparatus is disclosed. The method includes, when usage information of a buffer in a device satisfies a preset first condition, determining at least one first queue from the buffer, and performing congestion control on the at least one first queue, where the first condition includes a first threshold corresponding to the usage information of the buffer, and the at least one first queue is a queue whose queue delay is greater than or equal to a queue delay threshold or whose queue length is greater than or equal to a queue length threshold in a plurality of queues in the buffer. In this way, the device triggers a condition of congestion control based on a buffer status.

摘要： 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.

摘要： The technology of this application relates to a flow characteristic extraction method and apparatus, and belongs to the field of network technologies. The method includes a network device that determines a burst parameter of a burst traffic segment of a received first packet flow, and determines a burst parameter of the first packet flow based on the burst parameter of the burst traffic segment of the first packet flow. The first packet flow is an elephant flow, the burst traffic segment indicates a burst degree of traffic within one period of time, the burst parameter of the burst traffic segment is a parameter used to describe the burst traffic segment, and the burst parameter of the first packet flow is a parameter used to describe at least one burst traffic segment included in the first packet flow.
