Abstract
A method and system for Transmission Control Protocol (TCP) packet loss recovery over a wireless link where the packet loss is due to a high Bit Error Rate (BER). Such a method and system allows the exponential growth of a TCP congestion window for every acknowledgement packet that is received after a retransmission timers expires and/or three duplicate acknowledgement packets are received. In such a scenario, a maximum amount of data is transmitted via the exponentially growing TCP congestion window thereby optimizing and increasing packet throughput. A method and system for setting the congestion window to a greater amount than originally set of the maximum allowed window size is also presented. Further, a method and system for, as the BER changes between low and high, automatically adjusting the congestion window size to be a variable of the maximum allowed window size and dynamically adjusting the packet size is presented.
