    Abstract: 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.

    Abstract: 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.

    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.

    Abstract: 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.
