The disclosed invention relates to a link layer gateway computer that
operates to communicate a data packet from a source host computer in a first
network to a destination host computer in a second network.
Claim 30 is illustrative of the claimed invention, and it reads as follows:
30. A link layer gateway computer operable to communicate a data packet
from a source host computer selected from one of a plurality of host computers
coupled to a first network medium to a destination host computer selected from
one of a plurality of host computers coupled to a second network medium,
wherein:
a first network interface circuit enables connection of said link layer gateway
computer to said first network medium; and
a second network interface circuit enables connection of said link layer
gateway computer to said second network medium;
the link layer gateway computer has an assigned protocol address and a
computer protocol handler;
responsive to either of the first and second network interface circuits
receiving a data packet, the computer protocol handler evaluates a destination
protocol address in the received data packet;
the computer protocol handler is responsive to the received data packet if the
destination protocol address corresponds to the assigned address of the link layer
gateway computer;
