Abstract:
1. A method for notifying a sending device of network congestion on a network comprising at least the sending device and a receiving device, the method comprising: interpreting, by the receiving device, at least one condition on the network as an indication of the network congestion using a network congestion notification mechanism, wherein interpreting comprises inferring that at least one intermediate device on the network is experiencing the network congestion regardless of whether the at least one intermediate device is configured to explicitly notify the receiving device of the network congestion; generating, by the receiving device, a congestion notification signal using the network congestion notification mechanism, wherein the congestion notification signal includes a reference indicative of the network congestion; sending the congestion notification signal to the sending device, wherein the sending device monitors the reference for the network congestion; and generating and sending to the sending device at least one second congestion notification signal until the sending device provides an indication to the receiving device that the sending device has reduced its rate of transmission.
