Abstract
A router is operative to perform the following actions for each one of a plurality of wireless devices operating in a wireless network. The router initially transmits a number of data packets matched for a window size which corresponds to a default window size. The router then measures a round trip time (RTT) associated with communication of each of the transmitted packets. The router increases the window size if the RTT associated with the communication of each of the transmitted packets is within a first threshold. On the other hand, the router decreases the window size if the RTT associated with the communication of any of the transmitted packets is more than the first threshold but less than a second threshold. The router sets or updates at least one of the first or the second thresholds based on traffic communicated to the plurality of wireless devices via the router.
