  • Systems, methods and computer program products for adjusting a timeout for message retransmission based on measured round-trip communications delays
    Patent number: 6405337
    Abstract: A round-trip communications delay between two devices that communicate with one another over a communications network is repeatedly measured. An adjustable retransmission timeout is adjusted based upon at least one of the round-trip communications delays that are repeatedly measured. A message that is not acknowledged during the adjustable retransmission timeout is retransmitted. Accordingly, the overall communications speed between the two devices may be increased by accounting for the actual delay that is present in a network at a current time, and basing an adjustable retransmission timeout on this actual delay.
