摘要： A system processes packet data received in a number of incoming streams of variable speeds. The system includes an input interface, input logic, and one or more packet processors. The input interface receives the packet data and outputs the data using a first arbitration element. The input logic includes flow control logic, a memory, and a dispatch unit. The flow control logic initiates flow control on the data output by the input interface. The memory stores the data from the input interface. The dispatch unit reads the data from the memory using a second arbitration element. The packet processor(s) process the data from the dispatch unit.

摘要： A hierarchical traffic policer may include a first policer configured to pass first packets when a first condition is met. The first policer also may alter selection information within the passed first packets. A second policer may be configured to pass second packets when a second condition is met. The second policer may be further configured to pass all of the passed first packets from the first policer based on the altered selection information within the passed first packets.

摘要： A device includes an input processing unit and an output processing unit. The input processing unit dispatches first data to one of a group of processing engines, records an identity of the one processing engine in a location in a first memory, reserves one or more corresponding locations in a second memory, causes the first data to be processed by the one processing engine, and stores the processed first data in one of the locations in the second memory. The output processing unit receives second data, assigns an entry address corresponding to a location in an output memory to the second data, transfers the second data and the entry address to one of a group of second processing engines, causes the second data to be processed by the second processing engine, and stores the processed second data to the location in the output memory.

摘要： A bandwidth divider and method for allocating bandwidth between a plurality of packet processors. The bandwidth divider includes a plurality of counters for measuring the bandwidth of data packets transferred from the bandwidth divider to a respective packet processor; and a controller for analyzing the plurality of counters and transferring a data packet to a selected packet processor based on the contents of the counters. The method monitors the bandwidth consumed by the packet processors; determines, based on the bandwidth consumed by the packet processors, which packet processor has consumed the least amount of bandwidth; and allocates a next data packet to the packet processor which has consumed the least amount of bandwidth.

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.
