摘要： Embodiments of the present invention disclose a queue flushing method and a related device. The method includes: scanning, by a queue flushing processor, a flushing status of a valid queue from a queue information table, and determining a target queue whose flushing status is "to be flushed" in the queue information table, where the queue information table is used to record the flushing status of the valid queue; modifying, by the queue flushing processor, the flushing status of the target queue to "start flushing"; and flushing, by the queue flushing processor, the target queue, where the flushing status of the target queue is modified to "flushing complete" after the target queue is flushed. During implementation of the embodiments of the present invention, a priority of the target queue does not need to be considered, and multiple queues may be simultaneously scanned and flushed. This ensures a queue flushing completion time, thereby improving a queue batch flushing capability.

摘要： This application provides a data switching apparatus and a data switching method, and relates to the field of communications technologies, to reduce power consumption and a delay of data switching. The data switching apparatus includes a plurality of dies, and each die includes a divider, a switching unit, a combiner, and four interfaces. An input end of the divider is coupled to a first interface, a first output end of the divider is coupled to a first input end of the switching unit, a second output end of the divider and a second input end of the switching unit are both coupled to a second interface, a first output end of the switching unit is coupled to a first input end of the combiner, a second output end of the switching unit and a second input end of the combiner are both coupled to a third interface, and an output end of the combiner is coupled to a fourth interface. A third interface of each of the plurality of dies is coupled to a third interface of another of the plurality of dies, and a second interface of each of the plurality of dies is coupled to a second interface of still another of the plurality of dies.

摘要： A method, node, and system for traffic transmission are provided, and are applied to a ring link, where the ring link includes a first node, a second node, a third node, and a fourth node in sequence. The method includes: The first node receives first traffic, where the first node is a source node that sends the first traffic on the ring link; and the first node sends the first traffic to the third node, where two reachable paths with equal hop counts are included from the first node to the third node, the first node sends the first traffic to the third node on a preset first transmission path, the first transmission path passes through the second node, and the first transmission path is one of the two reachable paths with equal hop counts. This method can reduce computing load of nodes while implementing non-blocking switching of traffic between the nodes.
