摘要： Methods and systems consistent with the present invention provide a programmable table which allows software to define a plurality of branching functions, each of which maps a vector of condition codes to a branch offset. This technique allows for a flexible multi-way branching functionality, using a conditional branch outcome table that can be specified by a programmer. Any instruction can specify the evaluation of arbitrary conditional expressions to compute the values for the condition codes, and can choose a particular branching function. When the processor executes the instruction, the processor's arithmetic/logical functional units evaluate the conditional expressions and then the processor performs the branch operation, according to the specified branching function.

摘要： Methods and systems consistent with the present invention provide efficient packet replication in a router in order to multicast a stream of data. Packets are replicated and processed in a multithreaded environment. Embodiments consistent with the present invention implement a two-stage process for packet replication. The first stage thread will recirculate the packet to multiple second-stage threads. These second-stage threads will then create one or more outgoing copies of the packet. In this way, the copies are handled by multiple threads running in parallel.

摘要： Systems and methods of various embodiments provide mechanisms to support synchronous and asynchronous transactions. Distinct encodings allow an instruction to choose whether to perform any operation synchronously or asynchronously. Separate synchronous and asynchronous result registers hold the data returned in the most recent replies received for synchronous and asynchronous transaction requests, respectively. A status bit indicates whether an asynchronous transaction request is currently outstanding.

摘要： In one embodiment, a processor-readable medium can store code representing instructions that when executed by a processor cause the processor to receive a value representing a congestion level of a receive queue and a value representing a state of a transmit queue. At least a portion of the transmit queue can be defined by a plurality of packets addressed to the receive queue. A rate value for the transmit queue can be defined based on the value representing the congestion level of the receive queue and the value representing the state of the transmit queue. The processor-readable medium can store code representing instructions that when executed by the processor cause the processor to define a suspension time value for the transmit queue based on the value representing the congestion level of the receive queue and the value representing the state of the transmit queue.

摘要： In general, techniques are described for flexible packet processing. A network device for processing a data packet comprise a packet processing engine and a special handling unit external from the packet processing engine. The packet processing engine includes one or more of a plurality of pipelined packet processing units that, when processing the data packet, generate one or more events and determine whether to associate a trap and/or a sampling class with the data packet based on the generated events. The pipelined packet processing units then set bits of a vector that is passed between the pipelined packet processing units to associate the packet with the determined trap and/or sampling class, and processes the packet based on the set one or more bits of the vector.
