摘要： A system permits queues to use more than an allocated amount of bandwidth. The system allocates an amount of bandwidth to each of the queues and determines whether any of the queues is using less than the allocated amount of bandwidth. If so, the system reallocates the allocated bandwidth from one of the queues to at least one other one of the queues based on the amount of bandwidth used by each of the queues.

摘要： A system that processes single stream multicast data includes multiple queues, a dequeue engine, and/or a queue control engine. The queues temporarily store data. At least one of the queues stores single stream multicast data. A multicast count is associated with the single stream multicast data and corresponds to a number of destinations to which the single stream multicast data is to be sent. The dequeue engine dequeues data from the queues. If the data corresponds to the single stream multicast data, the dequeue engine examines the multicast count associated with the single stream multicast data and dequeues the single stream multicast data based on the multicast count. The queue control engine examines one of the queues to determine whether to drop data from the queue and marks the data based on a result of the determination.

摘要： A system provides congestion control in a network device. The system includes multiple queues, a dequeue engine, a drop engine, and an arbiter. The queues temporarily store data. The dequeue engine selects a first one of the queues and dequeues data from the first queue. The drop engine selects a second one of the queues to examine and selectively drop data from the second queue. The arbiter controls selection of the queues by the dequeue engine and the drop engine.

摘要： A system determines bandwidth use by queues in a network device. To do this, the system determines an instantaneous amount of bandwidth used by each of the queues and an average amount of bandwidth used by each of the queues. The system then identifies bandwidth use by each of the queues based on the instantaneous bandwidth used and the average bandwidth used by each of the queues.

摘要： A system provides congestion control and includes multiple queues that temporarily store data and a drop engine. The system associates a value with each of the queues, where each of the values relates to an amount of memory associated with the queue. The drop engine compares the value associated with a particular one of the queues to one or more programmable thresholds and selectively performs explicit congestion notification or packet dropping on data in the particular queue based on a result of the comparison.

摘要： A system selectively drops data from queues. The system includes a drop table that stores drop probabilities. The system selects one of the queues to examine and generates an index into the drop table to identify one of the drop probabilities for the examined queue. The system then determines whether to drop data from the examined queue based on the identified drop probability.

摘要： A system selectively drops data from a queue. The system includes queues that temporarily store data, a dequeue engine that dequeues data from the queues, and a drop engine that operates independently from the dequeue engine. The drop engine selects one of the queues to examine, determines whether to drop data from a head of the examined queue, and marks the data based on a result of the determination.
