Appeal No. 2007-0028
Application No. 10/694,277
wherein the link layer gateway computer is programmed to execute a link
layer protocol handler coupled to communicate with each of the first and second
network interface circuits;
wherein, responsive to either of the first and second network interface
circuits receiving a data packet comprising an address pairing communication, the
link layer protocol handler evaluates a destination protocol address in the received
data packet;
wherein, responsive to determining that the destination protocol address
does not correspond to the assigned address of the link layer gateway computer, the
link layer protocol handler determines if a source host computer which transmitted
the received data packet and the destination host computer designated by the
destination protocol address are not on the same one of either the first network
medium or the second network medium;
wherein:
responsive to the link layer protocol handler determining that the
source host computer which transmitted the received data packet and the
destination host computer designated by the destination protocol address are not on
the same one of either the first network medium or the second network medium,
the link layer protocol handler communicates a reply data packet to the source host
computer which transmitted the received data packet;
the reply data packet comprises an address pairing; and
the address pairing comprises the destination protocol address and a
hardware physical address corresponding to a selected one of the first network
interface circuit or the second network interface circuit, wherein the selected
network interface circuit is coupled to the same network medium as the source host
computer which transmitted the received data packet.
