Abstract
In one example, a method in a wireless router system for transmitting data packets to a mobile device through a wireless network based upon a round trip time is provided. A number of packets matched for a window size are transmitted to the mobile device, and a round trip time is measured. The window size for data packet transmission is re-sized by increasing the window size if the round trip time is within a first threshold, and decreasing the window size if the round trip time is more than the first threshold but less than a second threshold. The window size is also decreased if the round trip time is more than the second threshold, where each such data packet is further marked as a lost packet. A number of packets matched for the re-sized window is subsequently transmitted, including a retransmission any packets marked as lost.
