ABSTRACT:
A method and arrangement for initiating forwarding of data from a device having multiple receive and transmit ports as a function of the data received at the device includes a plurality of ports for receiving and transmitting data. A port vector FIFO forwards a data identifier to initiate forwarding from at least one of the ports of a received set of data. A holding area is controlled by the port vector FIFO and receives data identifiers and holds these data identifiers until released by the port vector FIFO. The release of a data identifier initiates the forwarding of the data, and each data identifier uniquely identifies each set of data received at the device. The port vector FIFO, upon receiving a data identifier, uses the data identifier to determine the receive port that is receiving the set of data identified by the data identifier. It then determines the mode of that receive port, and releases the data identifier in accordance with the designated mode of that receive port and the data received at that receive port.
