摘要： In general, the invention is directed to techniques for reducing deadlocks that may arise when performing fabric replication. For example, as described herein, a network device includes packet replicators that each comprises a plurality of resource partitions. A replication data structure for a packet received by the network device includes packet replicator nodes that are arranged hierarchically to occupy one or more levels of the replication data structure. Each of the resource partitions in each of the plurality of packet replicators is associated with a different level of the replication data structure. The packet replicators replicate the packet according to the replication data structure, and each of the packet replicators handles the packet using the one of the resource partitions of the packet replicator that is associated with the level of the replication data structure occupied by the node that corresponds to that particular packet replicator.

摘要： In one embodiment, a method can include receiving at an egress schedule module a request to schedule transmission of a group of cells from an ingress queue through a switch fabric of a multi-stage switch. The ingress queue can be associated with an ingress stage of the multi-stage switch. The egress schedule module can be associated with an egress stage of the multi-stage switch. The method can also include determining, in response to the request, that an egress port at the egress stage of the multi-stage switch is available to transmit the group of cells from the multi-stage switch.

摘要： A network device receives traffic associated with a network of intermediate network devices and user devices, classifies the received traffic, and allocates the classified traffic to traffic queues. The network device also schedules particular queued traffic, provided in the traffic queues and bound for particular intermediate network devices, using a hybrid weighted round robin (WRR) scheduler where the hybrid WRR scheduler schedules the particular queued traffic according to one of a 1-level WRR schedule, a 1.5 level WRR schedule, or a 2-level WRR schedule. The network device further provides the particular queued traffic to the particular intermediate network devices based on the scheduling of the hybrid WRR scheduler.

摘要： A network device includes one or more sprayers, multiple packet processors, and one or more desprayers. The sprayers receive packets on at least one incoming packet stream and distribute the packets according to a load balancing scheme that balances the number of bytes of packet data that is given to each of the packet processors. The packet processors receive the packets from the sprayers and process the packets to determine routing information for the packets. The desprayers receive the processed packets from the packet processors and transmit the packets on at least one outgoing packet stream based on the routing information.

摘要： In general, techniques are described that insert one or more bits into a digital bit stream to maintain an overall transition density in the digital bit stream. Maintaining the overall transition density facilitates the generation of a recovered clock by a phase-locked loop (PLL) circuit of a receiver. For example, when a data transition ratio for a portion of the digital bit stream is less than a desired data transition ratio, the techniques insert additional bits to increase the overall transition density of the digital bit stream.
摘要翻译：通常，描述了将一个或多个比特插入到数字比特流中以保持数字比特流中的总体转移密度的技术。维持整个转换密度有助于通过接收机的锁相环（PLL）电路产生恢复的时钟。例如，当数字比特流的一部分的数据转换比小于期望的数据转换比时，该技术插入附加比特以增加数字比特流的整体转换密度。
