Abstract:
1. A method performed by a transmitting computer that originally transmits over a network comprised of links to receiving computers, the method comprising: transmitting packets over the network to destination computers, wherein the transmitting is performed at a transmitting rate that changes over time; obtaining network observations that at times indicate congestion of a portion of the network carrying packets transmitted by the transmitting computer; and changing the transmitting rate of the transmitting computer by correlating the network observations with previous rates of transmission of the transmitting computer, wherein a congestion level signal is computed based on the network observations, and wherein the changing is performed such that an amount of rate adaptation is proportional to a computed degree of correlation between the congestion level signal and computed actual congestion, and wherein an operating congestion level used for changing the transmitting rate corresponds to a rate of transmission at or above which transmitted packets will experience observable loss and/or delay as a result of congestion of the portion of the network.
