Abstract
A network device for transferring data from a first network to a second network comprises a switch comprising a first port adapted to receive a frame of the data from the first network and a second port adapted to transmit the frame to the second network. The frame comprises a plurality of words including a first word comprising a first portion of an internet protocol address and a second word comprising a second portion of the internet protocol address. The switch adds one or more bits to the frame so that the first and second portions of the internet protocol address appear within a single word of the frame. A processor receives the frame from the switch, and to modify the internet protocol address in the frame. The switch receives the frame from the processor, and removes the one or more bits from the frame before the second port transmits the frame to the second network.
