Patent ID: 8004981

Claim:
A gateway between a first network and a second network, the second network comprising a TCP/IP network, the gateway comprising: a transmission buffer for first data awaiting transmission on the first network; and a reception buffer that receives second data from the second network, the gateway being configured to determine a first flow condition of the first network by inspecting the transmission buffer for packets awaiting transmission on the first network and modulate a second flow condition of the second network responsive to the first flow condition by controlling data transfers between the reception buffer and the transmission buffer, wherein data transfers between the reception buffer and the transmission buffer are controlled by generating by the gateway and sending by the gateway one or more acknowledgments to a source on the second network for a data packet that has previously been received by the gateway from the source on the second network, wherein the data packet is addressed to a receiver on the first network, wherein the gateway is a device that is separate from the receiver on the first network, wherein the first flow condition comprises congestion on the first network; wherein acknowledgments are generated and transmitted to the source on the second network in response to transferring to the transmission buffer packets originating the generation and sending of acknowledgments by the gateway.
