Abstract
In a speed converter for an IEEE-1394 serial bus network, first and second communication device nodes are attached to first and second buses. A first transceiver node receives an inbound first packet at a first speed from the first bus and transmits an inbound second packet, which is received from the second bus by a second transceiver node at a second speed, as an outbound second packet at the first speed to the first bus. The second transceiver node transmits the inbound first packet as an outbound first packet at a second speed to the second bus. Header translation circuitry translates the destination identifier of the inbound first packet to the destination identifier of the outbound first packet according to a mapped relationship between the first transceiver node and the second communication node, and translates the destination identifier of the inbound second packet to the destination identifier of the outbound second packet.
