摘要： A method and system for reducing arbitration latency employs speculative transmission (STX) without prior arbitration in combination with routing fabric scheduled arbitration. Packets are sent from source locations to a routing fabric through scheduled arbitration, and also through speculative arbitration, to non-contentiously allocate outputs that were not previously reserved in the routing fabric to the speculatively transmitted packets.

摘要： For switching or transmitting data packets, one can provide communication systems which consist of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master (21), the others are slave modules (22) controlled by control signals (25) derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.

摘要： Disclosed is a method for validating a data packet by a network processor supporting a first-network protocol and a second network protocol and utilizing shared hardware. The network processor receives a data packet; identifies a network packet protocol for the data packet; and processes the data packet according to the network packet protocol comprising: updating a first register with a first partial packet length specific to the first network protocol; updating a second register with a second partial packet length specific to the second network protocol; and updating a third register with a first checksum computed from fields independent of the network protocol. The method produces a second checksum utilizing a function that combines values from the first register, the second register, and the third register. The method validates the data packet by comparing the data packet checksum to the second checksum.
