摘要： A buffer module includes N queues configured to buffer M data streams, where N is less than M. A counting module includes M counters, the M counters are in a one-to-one correspondence with the M data streams, and the M counters are configured to count buffer quantities for the M data streams in the N queues. The control module is configured to, when a count value on a first counter exceeds a corresponding threshold, discard a to-be-enqueued data packet of a data stream corresponding to the first counter, or control the sending module to send pause indication information to an upper-level control module.

摘要： This application provides a network device, including a buffer module, a counting module, a control module, and a sending module. The buffer module includes N queues, configured to buffer M data streams, where N is less than M. The counting module includes M counters, the M counters are in a one-to-one correspondence with the M data streams, and the M counters are configured to count buffer quantities for the M data streams in the N queues. The control module is configured to: when a count value on a first counter exceeds a corresponding threshold, discard a to-be-enqueued data packet of a data stream corresponding to the first counter, or control the sending module to send pause indication information to an upper-level control module. On one hand, resource consumption of the network device can be reduced. On the other hand, buffer pressure of the network device can be released.

摘要： 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.

摘要： Embodiments of the present invention provide a capability negotiation method, system and apparatus, which are applied to the field of communications, and can improve the flexibility of capability negotiation. The capability negotiation method is applied to a base station, including: acquiring a gateway capability identifier, where the gateway capability identifier is a description of an end to end quality of service EtoE QoS control capability of a gateway; parsing the gateway capability identifier to obtain the EtoE QoS control capability of the gateway; and determining whether the EtoE QoS control capability of the gateway matches a local EtoE QoS control capability, so that when the EtoE QoS control capability of the gateway matches the local EtoE QoS control capability, EtoE QoS control is established.
