writing the destination address of the server 430 in the
destination address field 252. See page 11 of Appellants’
specification. At block 524, the broker 420 transmits to the
server 430 a packet. Since the client 410 already has

client 410 transmits packets to server 430 through the broker
420. At block 532, the broker 420 generates a pseudo
acknowledgment packet to the client 410. The pseudo
acknowledgment is generated after the broker 420 receives a
acknowledgment packet from the server 430. The pseudo

of Appellants’ specification. At block 534, for all data packets
received from the client 410, the broker 420 modifies the
destination address shown in figure 2 by writing the destination
address of the server 430 in the destination field 252. At block
