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.

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： 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： Plural arbiters arbitrate over a set of queues. The arbiters are constructed as a series of pipelined stages. Conflict detection logic detects conflicts among the arbiters in arbitrating across the queues, and, when a conflict is detected, the conflict detection logic alters processing related to conflicting queues in one arbiter when another arbiter has not passed a predetermined commit point in processing the queue.
摘要翻译：多个仲裁者对一组队列进行仲裁。仲裁者被构建为一系列流水线阶段。冲突检测逻辑检测仲裁者之间跨越队列进行仲裁的冲突，并且当检测到冲突时，当另一个仲裁器在处理队列时尚未通过预定提交点时，冲突检测逻辑改变与一个仲裁器中的冲突队列有关的处理。

摘要： A system includes a group of devices and a shared memory that is partitioned into blocks that are capable of being allocated to the group of devices using linked lists. The system also includes check logic configured to store a group of bits, where each bit corresponds to one of the blocks, and counter logic configured to count for a predetermined period of time. The system further includes logic configured to clear the group of bits stored in the check logic, cause the counter logic to count for the predetermined period of time, monitor a de-allocation of the blocks in the shared memory, set, for each of the blocks that is de-allocated during the predetermined period of time, the corresponding bit in the check logic, identify, after the predetermined period of time, one or more bits that have not been set, and mark the blocks corresponding to the one or more bits as available for allocation.
