摘要： A hierarchical round robin arbiter includes a first set of arbitration vectors, each associated with a plurality of requesters. A second arbitration vector includes one bit for each arbitration vector in the first set. The single bit informs the round robin arbiter if any of the requesters associated with the corresponding arbitration vector in the first set are requesting service. The round robin arbiter can determine whether one of a number of requesters is requesting service by examining the single bit in the arbitration vector.

摘要： An arbiter performs arbitration over a plurality of queues and provides data to a plurality of mutually exclusive destinations using combination logic that logically combines a plurality of mutually exclusive vectors into a combination vector. Each of the mutually exclusive vectors corresponds to one of the plurality of mutually exclusive destinations. A number of vector arbiters perform arbitration on each mutually exclusive vector to select a position within the mutually exclusive vector. A combination arbiter performs arbitration on the combination vector to determine a position within the combination vector, which corresponds to the next queue to be serviced. A comparison element compares the position within a mutually exclusive vector and the position within the combination vector to determine the destination of the data within the next queue to be serviced.

摘要： Output logic generates read requests using a programmable schedule that controls read bandwidth for multiple data streams and stores the read requests in a queuing device. The output logic also dequeues the read requests based on a similar programmable schedule, forwards the read requests to the memory, and reads data units from the memory based on the read requests.

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 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 processes data corresponding to multiple data streams. The system includes multiple queues that store the data, stream-to-queue logic, dequeue logic, and queue-to-stream logic. Each of the queues is assigned to one of the streams based on a predefined queue-to-stream assignment. The stream-to-queue logic identifies which of the queues has data to be processed. The dequeue logic processes data in the identified queues. The queue-to-stream logic identifies which of the streams correspond to the identified queues.

摘要： A network device constructs a notification corresponding to a received multicast data unit, where the notification includes administrative data associated with the multicast data unit that does not include a payload of the multicast data unit. The network device replicates the notification at least three different processing elements at different locations in a processing path of the network device to produce multiple replicated data items and produces a copy of the multicast data unit for each of replicated notifications. The network device forwards each copy of the multicast data unit towards a multicast destination.
